Spending $45 to $60 every month at laundromats gets old fast when you live on the road. I burned through hundreds of dollars and wasted entire afternoons sitting in fluorescent-lit laundromats before I decided enough was enough. My team and I spent three months testing 12 different models to find the best RV washing machine for different setups, tank capacities, and budgets.
Whether you are a full-time RVer, a weekend warrior, or someone who boondocks off-grid for weeks at a time, having clean clothes without leaving your rig changes everything. The right portable washer saves money, time, and the hassle of hauling laundry bags across unfamiliar towns. If you are also outfitting your rig with camping and RV lifestyle gear, getting your laundry sorted is a big quality-of-life upgrade.
In this guide, I break down 12 washing machines we tested specifically for RV life. I cover capacity, water usage, power draw, vibration during spin cycles, and how each one handles the realities of gray tanks and limited freshwater. Every model here runs on standard 120V power, so you can plug it into any RV outlet.

I ran the BLACK+DECKER BPWM09W through 40-plus loads over six weeks in my Class C motorhome, and it handled everything from sweaty hiking clothes to bed sheets without complaint. The 983 RPM spin cycle is the real standout here. Clothes came out barely damp, which meant I could hang them on a drying rack inside the rig and have them ready in about three hours.
Setup took about 10 minutes. The quick-connect sink adapter threaded onto my RV faucet without any leaks, and the drain hose hooked into my shower drain with a simple clamp. The LED display shows remaining cycle time, which is genuinely useful when you are planning your day around laundry and freshwater usage.

The five wash cycles cover most situations well. I used Heavy for muddy outdoor gear, Normal for everyday clothes, and Gentle for delicates. The auto unbalance detection worked as advertised. When I accidentally overloaded one side, the machine paused, redistributed the load, and resumed without slamming around the interior of my RV.
At 64 decibels, it is quieter than most portable washers I tested. I could run it during campground quiet hours without worrying about neighbors. The child lock feature is a nice bonus if you travel with kids who like to push buttons.

How Much Water Does It Use Per Load?
The BLACK+DECKER uses roughly 12 to 18 gallons per load depending on the water level you select. For RV owners with a 40-gallon freshwater tank, that means you can get two full loads before needing to refill. I typically ran laundry on medium water level, which used about 15 gallons and still got clothes clean.
Your gray tank capacity matters just as much. Each load adds the same volume to your gray tank, so plan your dumping schedule accordingly. If you are boondocking with limited tank space, stick to small loads on the low water setting.
Will It Shake My RV During Spin Cycle?
Thanks to the auto unbalance detection, vibration is well controlled. I noticed minimal shaking compared to twin tub models. Placing the unit on a level surface is critical. I used a small bubble level to check, and once leveled, the spin cycle produced a gentle hum rather than a violent shake.
For extra stability, I added a set of anti-vibration pads under the feet. That reduced transfer of any residual vibration into the RV floor. Overall, this is one of the most stable washers I tested for RV use.
2. Auertech 28lbs Twin Tub Washer – Best Twin Tub Value
- ✓ Built-in drain pump eliminates gravity drain hassles
- ✓ Massive 18lbs wash tub handles family loads
- ✓ Powerful 1300 RPM spin removes most water
- ✓ Lint filter included
- ✓ Overheat protection for motor safety
- ✕ Semi-automatic requires manual transfer between tubs

The Auertech 28lbs twin tub gave me the most capacity per dollar of any model in this test. With an 18-pound wash tub and 10-pound spin tub, I could wash a week’s worth of clothes for two people in about three loads. The separate tubs mean you can start washing a second load while the first one spins, which saves serious time.
The built-in drain pump is what makes this unit stand out from cheaper twin tubs. Instead of relying on gravity to drain water (which means finding a spot lower than your drain point), the pump pushes water up and out through the hose. In my RV, I could drain directly into the shower pan without any height tricks.

Cleaning performance impressed me. The 1300 RPM motor agitated clothes thoroughly, and even muddy pants from a desert hike came out clean on the first cycle. I used about a tablespoon of detergent per load, and the rinse cycle left no residue.
The spin tub is the secret weapon. At 1300 RPM, it extracted so much water that my clothes were only slightly damp coming out. I hung them on a retractable clothesline inside the RV, and they dried in about four hours on a dry day.

How Hands-On Is the Wash Process?
Being semi-automatic means you are involved in every step. You fill the wash tub manually, set the timer, let it agitate, then manually move clothes to the spin tub. After spinning, you return clothes to the wash tub for a rinse cycle, then back to the spin tub for a final spin.
It sounds tedious, but I got into a rhythm after two loads. The advantage is total control over water usage and cycle length, which matters a lot when boondocking. You can use exactly as much water as you need and no more.
Is the Noise Level Acceptable for Campgrounds?
The Auertech is louder than the fully automatic models on this list. During the spin cycle, I measured about 70 decibels, which is similar to a vacuum cleaner running in the next room. I would not run it during quiet hours.
During the wash cycle, the agitator produces a steady hum that is less noticeable. I typically ran loads during mid-afternoon when campgrounds are naturally busier and no one seemed bothered by the sound.
3. SUPER DEAL Compact Twin Tub – Best Budget Pick
- ✓ Lowest price point of any tested model
- ✓ Twin tub design for simultaneous wash and spin
- ✓ 1300 RPM motor cleans effectively
- ✓ Extremely lightweight at 26.5 lbs
- ✓ Pays for itself in under 2 months vs laundromat
- ✕ Gravity drain limits placement options
- ✕ Spinner basket is small at 5 lbs
- ✕ Hose may not fit all faucets
- ✕ Can run hot with back-to-back loads
- ✕ More manual involvement required

At under $90, the SUPER DEAL twin tub is the model I recommend to RVers who want to test whether on-board laundry works for their lifestyle without a big investment. One Reddit user in the Frugal community put it perfectly: they bought a similar unit for $250 brand new and said it was well worth it. At this price point, you are paying even less.
I tested this unit for three weeks in a travel trailer. The 8-pound wash tub is enough for about four days of clothes for one person. The 5-pound spin tub is smaller, so I had to spin in two batches per wash load, but the 1300 RPM motor got clothes surprisingly dry.

The gravity drain is the main trade-off. You need to place the washer above your drain point, or the water will not flow out. In my RV, I set it on a folding table next to the shower and ran the drain hose down into the shower pan. It worked, but it is less flexible than a pump-driven model.
Build quality is what you would expect at this price. The plastic tub feels lightweight, and the translucent lid lets you monitor the wash. After 25 loads, everything still worked fine, though I noticed the motor area got warm during back-to-back loads.

Is the Capacity Enough for Two People?
For two people living full-time in an RV, the 8-pound wash capacity means doing laundry every two to three days. That is more frequent than a larger unit, but each load takes only 15 minutes of wash time plus 5 minutes of spin. You can knock out a week’s laundry in about 90 minutes of active time.
If you travel solo or only need laundry for weekend trips, this capacity is plenty. For families of three or more, consider stepping up to the Auertech 28lbs or the COSTWAY 20lbs.
How Long Will This Budget Washer Last?
Based on forum reports and my testing, expect 1 to 2 years of regular use before something needs replacement. The most common failure point is the spin motor bearings, which wear faster under heavy use. For the price, even one year of service pays for itself many times over compared to laundromat costs.
To extend its life, avoid overloading, let the motor cool between loads, and store it inside during freezing weather. Several RV forum users reported their units lasting over two years with careful use.
4. Auertech 14lbs Fully Automatic Portable Washer
- ✓ Fully automatic means no manual water filling or tub transfers
- ✓ 10 wash cycles including Quick and Bulky
- ✓ Glass soft-close lid prevents slamming
- ✓ Child safety lock included
- ✓ 95 percent spin dry efficiency
- ✓ Drain pump with 4.1 ft hose
- ✕ Some users report shorter drain hose than expected
- ✕ Water pressure sensitivity on some setups
- ✕ 35 lb unit is heavier than twin tubs
- ✕ Load capacity may be limited for bulky items

The Auertech 14lbs fully automatic washer is the upgrade path from twin tub models. Instead of manually moving clothes between wash and spin tubs, you load it, select a cycle, and walk away. For RVers who want the experience closest to a home washing machine, this is the sweet spot of price and convenience.
I tested 10 wash cycles over four weeks, and the ones I used most were Standard for everyday clothes, Quick Wash for lightly soiled items, and Bulky for bedding and jackets. The 360W motor cleaned effectively across all cycles, and the 1300 RPM spin left clothes about 95 percent dry.

The soft-close tempered glass lid is a detail I did not know I needed. In an RV where space is tight, a lid that will not slam shut from road vibration or a bump is genuinely useful. The transparent glass also lets you check on the wash without opening the lid.
The built-in drain pump with its 4.1-foot hose gave me flexibility in placement. I positioned the washer next to my RV bathroom vanity and ran the drain hose into the shower drain without any height issues.

Does the Fully Automatic Cycle Save Water?
The automatic water level selection helps manage consumption. On the lowest setting, I measured about 10 gallons per load. The medium setting used about 14 gallons, and the highest used about 18 gallons. For RV use, I stuck to low and medium almost exclusively.
Compared to manually filling a twin tub, the automatic system actually uses slightly more water because it fills and drains for each rinse cycle. However, the convenience of walking away during the cycle is a fair trade for most RVers.
Can You Run It While Driving?
No, and you should never run any washing machine while the RV is in motion. The vibration from driving combined with the spin cycle could damage both the washer and your RV. Always run laundry when parked and leveled. The 24-hour delay start feature is handy for setting a load to begin when you arrive at your destination and get hooked up.
5. COMFEE 1.6 Cu.Ft Portable Washing Machine
- ✓ Saves up to 84 percent energy compared to similar models
- ✓ Stainless steel inner tub for durability
- ✓ Child Lock and Delay Start features
- ✓ Reloading feature lets you add clothes mid-cycle
- ✓ Quiet at 62 decibels
- ✓ Built-in wheels for easy movement
- ✕ 79.4 lbs is heavy for some RV floors

Built-in wheels
The COMFEE 1.6 cu.ft washer earned its spot as the most energy-efficient model I tested. According to the manufacturer, it uses up to 84 percent less energy than comparable portable washers. For RVers running on solar or generator power, that translates to fewer amp-hours consumed per load.
I measured actual power draw during a Normal cycle at about 280 watts during wash and 350 watts during spin. Over a 45-minute cycle, that is roughly 0.2 kWh per load. Running it off my 2000-watt inverter generator was no problem at all.

The 11-pound capacity is enough for a couple’s daily laundry. The six wash programs cover Normal, Heavy, Delicate, Quick, Bulky, and Spin Only. I used Quick most often for lightly worn clothes and Heavy for towels and jeans after outdoor adventures.
The stainless steel tub is a step up from the plastic drums found in cheaper twin tubs. It resisted staining and odor buildup even after a month of use. The clear lid lets you watch the cycle progress, which is oddly satisfying.

How Quiet Is 62 Decibels in an RV?
At 62 decibels, the COMFEE is about as loud as a normal conversation. I could run it while watching TV without turning up the volume much. During the spin cycle, noise increased slightly but stayed below what I would call disruptive.
For comparison, the BLACK+DECKER measured 64 dB and the twin tub models all exceeded 68 dB. If campground courtesy is a priority, the COMFEE and BLACK+DECKER models are your best options.
Will My RV Floor Support 79 Pounds?
At 79.4 pounds plus a full load of wet clothes and water, this washer can weigh over 100 pounds in operation. Most RV floors handle this fine, but check the area near your planned installation spot. Slide-out floors and areas above the gray tank are typically reinforced.
I placed mine on a rubber anti-vibration mat over the vinyl flooring in my RV bathroom. The built-in wheels made it easy to roll into position, and the unit stayed stable once leveled. If your floor flexes noticeably when you walk on it, consider a plywood reinforcement panel.
6. BLACK+DECKER 2.0 Cu.Ft Portable Washer
- ✓ Largest capacity among tested portable models
- ✓ 3 temperature settings including hot wash
- ✓ 15.4 lb load handles bedding and bulky items
- ✓ Very quiet operation
- ✓ Delay start up to 24 hours
- ✓ Adjustable leveling legs included
- ✕ Drain hose must be elevated 34 inches or water drains prematurely

The BLACK+DECKER 2.0 cu.ft is the largest capacity washer in this lineup, handling up to 15.4 pounds per load. For RV families or couples who want to wash bedding and bulky items, this is the model that eliminates the need for laundromat visits entirely.
I tested it with queen-size sheets, a sleeping bag, and a week of clothes for two people. Everything fit and came out clean. The three temperature settings are a meaningful upgrade over cold-water-only models. Warm wash made a visible difference on stained clothes.

The drain hose elevation requirement is the most important thing to know before buying. The hose must be positioned at least 34 inches above the floor, or water will drain continuously during the wash cycle. I looped the hose over a towel bar in my RV bathroom and it worked perfectly.
At 72 decibels during spin, it is louder than the 0.9 cu.ft BLACK+DECKER but still manageable. The auto unbalance detection kept vibration in check, and the stainless steel tub felt solid and well-built.

Does the Larger Capacity Justify the Price?
If you wash for two or more people, yes. The jump from 6.6 pounds (0.9 cu.ft) to 15.4 pounds (2.0 cu.ft) cuts your number of loads nearly in half. Over a year of full-time RV living, that saves significant time, water, and power.
For solo travelers or weekend campers, the 0.9 cu.ft model at half the price is the better value. You would be paying for capacity you do not use.
How Does the Temperature Selection Work?
The three temperature settings mix hot and cold water from your RV’s supply. For hot wash, the unit draws from your water heater. Keep in mind that RV water heaters typically hold only 6 to 10 gallons, so a hot wash cycle may deplete your supply.
I learned to run the water heater for 15 minutes before starting a hot wash. That ensured enough hot water for a full cycle without running the tank dry mid-wash.
7. COMFEE 0.9 Cu.Ft Compact Washer
- ✓ Compact 18.1 inch width fits tight RV spaces
- ✓ Built-in wheels for easy repositioning
- ✓ Auto unbalance detection prevents violent shaking
- ✓ DOE certified for energy efficiency
- ✓ Customizable wash program settings
- ✓ Rust-resistant stainless steel inner tub
- ✕ 840 RPM spin is slower than competitors
- ✕ Cycles may stop with severely unbalanced loads
- ✕ Short drain hose reported by some users
- ✕ 44 lbs may need floor reinforcement consideration

The COMFEE 0.9 cu.ft washer is the narrowest full-size automatic washer I tested at just 18.1 inches wide. That makes it ideal for RVs where every inch of cabinet or bathroom space matters. I slid it into a gap between my RV shower and the bathroom vanity with less than an inch to spare.
The five wash cycles cover the essentials: Heavy, Soft, Normal, Rapid, and Soak. I relied on Rapid for quick refreshes of lightly worn clothes and Heavy for towels after beach trips. The customizable program lets you adjust load size, wash time, rinse time, and spin time independently.

The auto unbalance detection (AUD) is what makes this unit RV-friendly. When clothes cluster on one side during spin, the AUD system pauses, redistributes the load, and restarts. This prevents the violent shaking that can damage RV cabinetry and send the washer walking across the floor.
At 840 RPM, the spin speed is slower than the 1300 RPM twin tubs, so clothes come out slightly wetter. I found that adding an extra 5 minutes of spin time in the custom settings improved dryness noticeably.

How Does It Compare to the BLACK+DECKER 0.9?
The COMFEE and BLACK+DECKER 0.9 cu.ft washers are direct competitors. The BLACK+DECKER wins on spin speed (983 RPM vs 840 RPM) and brand reputation. The COMFEE wins on price and the customizable wash program feature.
If you prioritize getting clothes as dry as possible, go BLACK+DECKER. If you want more control over cycle parameters and a lower price point, the COMFEE is the better pick.
What About the Built-In Wheels?
The wheels are a genuine convenience feature for RV use. I rolled the COMFEE out of its storage spot, connected it to the sink, ran a load, drained it, and rolled it back into storage. This works well if you do not have a dedicated laundry space.
One caution: the wheels lock to prevent rolling during operation, but on a slick RV floor, I still recommend checking that the unit has not shifted after a spin cycle.
8. Giantex Full Automatic Portable Washer
- ✓ Fully automatic operation requires no manual intervention
- ✓ Built-in aluminum drain pump for flexible drainage
- ✓ Honeycomb-shaped inner tub protects fabrics
- ✓ 60 decibel quiet operation
- ✓ Six wash programs for different fabric types

The Giantex full automatic washer is a dependable choice for solo RVers or couples who want a set-and-forget laundry experience. The 8-pound capacity is modest, but the six wash programs and built-in drain pump make it a capable machine for daily use.
I ran the Giantex through 30 loads over a month of testing. The honeycomb-shaped inner tub is designed to protect delicates from snagging, and I confirmed this with silk scarves and lightweight athletic wear. Everything came out clean without damage.

The built-in aluminum drain pump is reliable and moves water efficiently. I never experienced a backup or slow drain during testing. The three water levels (16L, 23L, and 30L) let you match water usage to load size, which is essential for managing freshwater tank levels.
At 60 decibels, the Giantex is one of the quietest automatic washers on this list. I could run a load during a Zoom call without the background noise being noticeable.

How Reliable Is the Giantex Long-Term?
With over 4,000 reviews and a 4.2-star average, the Giantex has a solid track record. The most common long-term issue reported is the water inlet valve developing leaks after 18 to 24 months. Replacing the valve is a $15 part and a 20-minute DIY job.
The aluminum drain pump is more durable than plastic alternatives found in cheaper models. Several users reported theirs lasting 3-plus years with regular use.
What Faucets Does the Inlet Hose Fit?
The included inlet hose comes with a standard adapter that fits most RV sink faucets with a threaded aerator. If your faucet does not have threads, you will need a universal faucet adapter (about $8 on Amazon). I had to buy one for my RV bathroom sink, and it solved the connection issue immediately.
9. COSTWAY Twin Tub 20lbs Washer
- ✓ Large 12 lb wash tub handles big loads
- ✓ 330W motor provides strong cleaning power
- ✓ Effective high-speed spin removes most water
- ✓ Lightweight at 29 lbs total
- ✓ Saves significant money versus laundromat visits
- ✓ Handles multiple fabric types well
- ✕ Gravity drain limits placement flexibility
- ✕ Spinner basket goes off balance easily
- ✕ Can be noisy during spin
- ✕ No built-in drain pump
- ✕ Short inlet hose may need extension

The COSTWAY 20lbs twin tub sits in the sweet spot between budget twin tubs and more expensive fully automatic models. The 12-pound wash tub and 8-pound spin tub give you enough capacity for a couple’s weekly laundry, and the 330W motor delivers noticeably stronger agitation than the 250W motors in cheaper models.
I tested the COSTWAY alongside the Auertech 28lbs, and the cleaning performance was comparable. The main difference is the COSTWAY lacks a drain pump, so you need gravity to work in your favor. In my RV, I placed it on a counter near the sink and let the drain hose empty into the basin.

The three-knob control system is straightforward. One knob selects wash mode, one sets the timer, and one controls the spin timer. No learning curve, no digital displays to decipher. Just set it and let it run.
The spin cycle’s tendency to go off balance was the most annoying issue. With unbalanced loads, the spinner would vibrate violently. I learned to distribute clothes evenly around the spinner basket, which solved the problem in most cases.

How Much Water Per Load?
The 12-pound wash tub holds about 10 gallons of water when filled to the recommended level. For RV use with a 40-gallon freshwater tank, that means three to four wash loads per tank. Each rinse cycle adds another 8 to 10 gallons.
I typically did two wash loads and one rinse per tank fill, which used about 25 gallons total and left enough water for dishes and a quick shower.
Is It Suitable for Boondocking?
For boondocking, the COSTWAY works if you are conservative with water. The semi-automatic design gives you precise control over how much water goes in. You can fill the wash tub with just 5 gallons for small loads, which is ideal when every drop counts.
However, the gravity drain means you need to be parked somewhere where you can drain into a container or approved gray water disposal. Plan your boondocking laundry days around your dump station visits.
10. INTERGREAT Portable Twin Tub Washer
- ✓ Large 9.6 lb wash tub for a twin tub
- ✓ Lid safety switch prevents operation with lid open
- ✓ Filter net catches lint and debris
- ✓ Multiple wash modes including Gentle
- ✓ Lightweight and portable design
- ✓ Saves time and money versus laundromat
- ✕ Spinner basket is small relative to wash tub
- ✕ Hoses may not fit all faucet types
- ✕ Can be loud when load is unbalanced
- ✕ Requires multiple spin loads per wash
- ✕ Some report motor smell initially

The INTERGREAT 18lbs twin tub offers a solid balance of capacity and price. The 9.6-pound wash tub handles more per load than the SUPER DEAL’s 8-pound tub, and the 1300 RPM motor spins clothes nearly dry. The lid safety switch is a thoughtful feature that prevents the spinner from running when the lid is open.
I noticed a slight motor smell during the first two loads, which is normal for new motors burning off manufacturing oils. By the third load, the smell was gone. The filter net on the side of the wash tub caught lint and pet hair effectively, which I appreciated since my dog travels with me.

The Gentle mode was gentle enough for my wool sweaters and synthetic hiking shirts. Normal mode handled everyday cottons and jeans. The gravity drain worked fine when I positioned the washer above my shower drain.
The mismatch between wash tub capacity (9.6 lbs) and spin tub capacity (5.4 lbs) means you need two spin cycles per wash load. This adds about 10 minutes to each load but is a common limitation of twin tub designs at this size.

How Does It Handle Delicates?
The Gentle mode reduces agitation speed and shortens the cycle duration. I tested it with silk camisoles, lace items, and a cashmere blend sweater. Everything came through undamaged and clean. For best results with delicates, use cold water and minimal detergent.
The spin tub can be too aggressive for very delicate items. I recommend hand-squeezing excess water from silks and wool instead of using the spinner.
What About Initial Motor Smell?
The motor smell some users report is from protective oils burning off the motor during the first few uses. It is harmless and dissipates quickly. Run two empty cycles with just water and a cup of white vinegar before your first real load to eliminate the smell faster.
11. Superday Portable Twin Tub Washer
- ✓ Silver ion technology provides antibacterial cleaning
- ✓ Quiet operation for a twin tub design
- ✓ Stable during wash and spin cycles
- ✓ Large 11.6 lb wash tub capacity
- ✓ Clear lids for monitoring
- ✓ Good for delicates and small loads
- ✕ Spinner basket is smaller than wash tub
- ✕ Power cord and drain hose may be too short
- ✕ May need multiple spin cycles for thorough drying
- ✕ Some long-term durability concerns reported

The Superday twin tub stands out for two reasons: silver ion cleaning technology and quieter-than-average operation for a twin tub. The metallic silver flakes in the water inlet system generate silver ions during washing, which the manufacturer claims provides antibacterial benefits.
I cannot verify the antibacterial claims scientifically, but I can confirm that clothes came out smelling fresher than with other twin tubs I tested. Even damp clothes left in the tub for an hour did not develop the musty smell I noticed with the SUPER DEAL model.

The Superday was noticeably quieter than the other twin tub models. The wash cycle produced a gentle sloshing sound rather than the aggressive churning of the COSTWAY or SUPER DEAL. During spin, vibration was controlled and the unit stayed planted on the counter where I positioned it.
The five wash time options (0, 3, 6, 9, 12, and 15 minutes) and five spin time options (0, 1, 2, 3, 4, and 5 minutes) give you precise control over cycle length. I used the 9-minute wash setting for most loads, which was plenty for everyday cleaning.

How Effective Is the Silver Ion Feature?
Silver ions have documented antimicrobial properties and are used in various consumer products. While I noticed fresher-smelling laundry, I would not rely on this feature alone for sanitizing heavily soiled items. Use hot water and proper detergent for sanitation.
The silver flakes are embedded in the water inlet system and do not require replacement or maintenance. They should last the lifetime of the machine.
Is It Stable During the Spin Cycle?
Yes, compared to other twin tubs, the Superday was one of the most stable. The wider base and lower center of gravity help. I still recommend placing it on a non-slip mat and ensuring the surface is level before starting a spin cycle.
With very unbalanced loads, some vibration is inevitable. Distribute clothes evenly in the spinner basket to minimize this. I found that wrapping large items around the spinner wall rather than stuffing them in the center produced the best balance.

Foldable design
The Minwoch foldable washer is a different category entirely from the other 11 models. It is designed for small items only: socks, underwear, baby clothes, and washcloths. Think of it as a supplemental washer that handles the daily essentials while you save bigger loads for a laundromat or a larger unit.
I tested it for two weeks using it exclusively for socks, underwear, and my dog’s travel blankets. The three modes (3-minute quick rinse, 5-minute gentle care, and 10-minute deep cleaning) cover the range from freshening up to actual cleaning. The 45-decibel noise level is nearly silent.

The foldable design is where this unit shines for RV use. When not in use, it collapses to about 4 inches tall and slides into a cabinet or under a seat. When deployed, it stands 12.9 inches tall and holds 20 liters of water.
The one-button operation is brilliantly simple. Press once for quick rinse, twice for gentle care, three times for deep cleaning. No knobs, no displays, no complicated settings. Fill it with water, add clothes and detergent, press the button.

What Can You Actually Wash in It?
Realistically, the Minwoch handles about 4 to 6 pairs of socks, 3 to 4 pairs of underwear, or 2 to 3 baby outfits per load. T-shirts and shorts are the upper limit of what fits. Jeans, towels, and bedding are out of the question.
For full-time RVers, this unit is best paired with a larger washer for big items. Use the Minwoch for daily small-item washing and save your main washer (or laundromat trips) for larger loads once a week.
Is It Worth It for Weekend Campers?
For weekend warriors who want clean socks and underwear without packing a week’s supply, absolutely. The foldable design means it takes up almost no space, and the quiet operation means you can run it at any hour. At under $50, it is an inexpensive convenience upgrade.
For anyone expecting to wash full outfits, look at the other 11 models instead. The Minwoch is a specialty tool, not a primary washer.
How to Choose the Best RV Washing Machine
Choosing the right portable RV washing machine comes down to five factors that directly impact your daily life on the road. Here is what to evaluate before buying.
Capacity: Match It to Your Household
Capacity is measured in pounds or cubic feet, and it determines how many loads you will do per week. For solo travelers, 6 to 8 pounds (0.9 cu.ft) is sufficient. Couples should aim for 10 to 14 pounds, and families need 15 pounds or more.
Remember that smaller capacity means more frequent loads, which means more water usage over time. Sometimes a slightly larger washer that does fewer loads is more water-efficient than a small one running constantly.
Water Usage and Tank Management
Every gallon that goes into your washer comes out of your freshwater tank and goes into your gray tank. A typical portable washer uses 10 to 18 gallons per load. If your freshwater tank holds 40 gallons and your gray tank holds 35 gallons, you can do roughly two full loads before needing to refill and dump.
Semi-automatic twin tubs give you the most control over water usage because you fill them manually. Fully automatic models are more convenient but may use more water per cycle since they handle rinsing automatically.
Power Requirements
All 12 washers on this list run on standard 120V household power, which means any RV outlet can handle them. Most draw between 250 and 400 watts during operation, well within the capacity of a 2000-watt generator or inverter. For broader power management solutions in your RV, a quality power strip with surge protection is worth adding near your washer setup.
One important note: never plug a washing machine into a GFCI outlet that also powers your RV refrigerator or air conditioner. The combined startup surge can trip the breaker and leave you without cooling or refrigeration mid-cycle.
Vibration and Floor Stability
This is the number one concern I hear from RV owners on forums. A washing machine that shakes violently during spin cycle can damage cabinetry, loosen screws, and even crack RV walls over time. Look for models with auto unbalance detection (AUD), which pauses and redistributes loads automatically.
Anti-vibration pads under the washer feet make a significant difference. I use rubber pads rated for washing machines on every unit I test. They cost about $15 and reduce vibration transfer to the RV floor by an estimated 40 percent.
Drain Pump vs Gravity Drain
Gravity drain washers require the unit to be positioned above the drain point. This works if you have a counter or elevated surface near a sink or shower. Drain pump models can push water upward through the hose, giving you more placement flexibility.
If your RV bathroom or kitchen layout does not easily accommodate an elevated washer position, spend the extra money on a model with a built-in drain pump. Models with pumps include the Auertech 28lbs, Auertech 14lbs, Giantex, COMFEE, and BLACK+DECKER units.
Frequently Asked Questions
What is the best RV washing machine?
The best RV washing machine overall is the BLACK+DECKER 0.9 cu.ft Portable Washer for its reliability, 983 RPM spin speed, auto unbalance detection, and trusted brand warranty. For budget-conscious RVers, the SUPER DEAL Compact Twin Tub offers excellent value at under $90. For maximum capacity, the BLACK+DECKER 2.0 cu.ft handles up to 15.4 pounds per load.
Is it worth having a washer and dryer in an RV?
Yes, for most RVers it is worth it. A portable washing machine saves $45 to $60 per month in laundromat costs, meaning a $150 washer pays for itself in about three months. Beyond money, the convenience of doing laundry without leaving your campsite saves 2 to 3 hours per week and eliminates the hassle of transporting dirty clothes to unfamiliar laundromats.
How much water do RV washing machines use?
Most portable RV washing machines use between 10 and 18 gallons per load depending on capacity and water level settings. Twin tub semi-automatic models give you the most control, allowing you to use as little as 5 gallons for small loads. Fully automatic models typically use 12 to 18 gallons per complete cycle including rinse.
Do portable washers really work for RV use?
Yes, portable washers work effectively for RV use when matched to the right situation. Models like the BLACK+DECKER and COMFEE deliver cleaning performance comparable to residential units. Twin tub models require more hands-on involvement but offer better water control for boondocking. All models tested here run on 120V power and connect to standard RV faucets.
Can you add a washer and dryer to any RV?
Most RVs can accommodate a portable washing machine if they have a 120V outlet, access to a water source (sink faucet), and a drain point (shower or sink). Portable units do not require permanent plumbing or modification. Built-in RV washers require pre-plumbed washer hookups, which are found in higher-end motorhomes and fifth wheels. Always check your RV floor weight rating before installing any washer.
Final Recommendations
After testing 12 models over three months of RV living, my top recommendation for the best RV washing machine is the BLACK+DECKER 0.9 cu.ft Portable Washer. It hits the perfect balance of cleaning power, spin efficiency, quiet operation, and brand reliability. The 983 RPM spin cycle leaves clothes nearly dry, and the auto unbalance detection keeps vibration to a minimum.
For RVers who want maximum capacity at the best price, the Auertech 28lbs Twin Tub is hard to beat. The built-in drain pump and 18-pound wash tub handle family laundry loads without breaking the budget. And if you just want to test whether on-board laundry works for your lifestyle, the SUPER DEAL Compact Twin Tub at under $90 is the lowest-risk entry point.
Whichever model you choose, the freedom of doing laundry in your own rig transforms the RV experience. No more laundromat runs, no more quarters, no more waiting for machines in unfamiliar places. Just clean clothes whenever you want them, wherever the road takes you.
