Key takeaways
- Measure vertical clearance, not just floor space: Top-loading lids need 12 to 18 inches of swing room above the machine. A unit that fits your galley footprint may still be unusable under an overhead cabinet, so check lid-open height before width.
- Match the drain method to your setup: Machines with a built-in drain pump can push water upward into a sink or out a window, which is essential when your gray tank inlet sits above floor level. Gravity-only drain hoses require the washer to sit higher than the drain point — rarely possible in an RV.
- Respect your amperage budget: Cold-fill portable washers typically draw 200 to 400 watts, which most 30-amp RV services handle comfortably alongside a fridge. Run the numbers if you’re on a small inverter or shore power shared with an A/C unit.
- Weigh spin quality over drum capacity: A high-extraction spin cycle is what makes RV laundry viable, since you’ll likely air-dry. Twin-tub machines with dedicated spinners generally wring out more water than compact single-tub automatics.
- Decide how much water you can spare: Fully automatic units fill and rinse on their own schedule, using more water per load. Twin tubs let you reuse wash water across multiple loads, which is a genuine advantage when you’re tank-dependent.
What's inside
Laundry in an RV is a logistics problem before it’s a cleaning problem. You’re working with a cabinet-sized footprint, a fresh water tank that empties faster than you’d like, a gray tank that fills faster than you’d expect, and a power system that may or may not tolerate a heating element. Most people solve it by hauling duffel bags to campground laundromats, which works until you’re three days into a boondocking stretch and every shirt smells like campfire. A portable washer changes that calculation, but only if you pick one that actually fits the way an RV works.
This guide looks at portable washers through a small-space lens: how much floor and vertical clearance each unit demands, how they handle drainage without a permanent hookup, what they draw on a 15-amp circuit, and whether they can spin clothes dry enough to line-dry in a day. I’ve grouped the picks by the two real design families — fully automatic single-tub machines and twin-tub manual units — because that choice matters more than capacity numbers on the box.

The Best Portable Washing Machine For Rv (2026)s Reviewed
28 lbs Fully Automatic Washer and Spin Dryer Combo
This is the machine for RVers with full hookups and a slide-out or wet bay to park it in — 10 cycles, five selectable water levels, and a 24-hour delay start mean you can set a load to finish right as you wake up. The 28-pound rating and drain pump make it the closest thing to a residential washer in this class, though its footprint demands real planning.
17.7 lb Full Automatic Portable Washer
The sweet spot for most travel trailers: enough drum for a two-person load of clothes without the bulk of the larger automatics, plus a 24-hour timer and 10 programs. The off-white finish and included drain hose make it easy to tuck into a bathroom corner and roll into position on wash day.
28 lb Twin Tub Washer with Drain Pump
Twin tubs are the pragmatist’s choice for boondocking, and this one pairs an 18-pound wash tub with a 10-pound spinner so you can wash one load while spinning the last. Water reuse and the built-in drain pump mean substantially less draw on your fresh tank than any automatic here.
14 lb Fully Automatic Washer with Glass Lid
Small rigs and Class B vans benefit from this one’s genuinely compact body, and the glass lid lets you spot an unbalanced load before it starts thumping against a cabinet wall. Ten cycles and a drain pump in this size class is unusual and worth the tradeoff in capacity.
COMFEE’ 1.6 Cu.ft Portable Washer
COMFEE’ builds this one with caster wheels standard, which solves the store-it-then-use-it shuffle that defines RV laundry better than any spec sheet feature. Eleven pounds of capacity and six programs suit light, frequent loads — the realistic rhythm for full-time travel.
Frequently Asked Questions
Can I run a portable washer while driving or dry camping?
Never while in motion — water sloshing in an unsecured drum is a real hazard. Dry camping is workable with a twin tub and a generator or adequate battery bank, since those units use the least water and power.
Where does the wastewater go?
Most RVers drain into the shower pan or bathroom sink, which routes to the gray tank. Confirm your tank capacity first: a single automatic wash cycle can add 10 to 15 gallons.
Do these connect to my RV water system?
Most include an inlet hose with a faucet adapter, which works with a standard galley or bathroom faucet. Some twin tubs can simply be filled by bucket or pitcher.
How long does a typical load take?
Fully automatic cycles run 30 to 60 minutes start to finish. Twin tubs are faster in raw wash time but require you to move laundry between tubs manually.
Final Thoughts
For most RVs with hookups, the 17.7 lb Full Automatic Portable Washer hits the right balance of capacity and footprint, while the COMFEE’ 1.6 Cu.ft is the better fit for vans and smaller rigs thanks to its wheels and modest power draw. If you spend real time off-grid, the 28 lb Twin Tub earns its space by letting you stretch a single tank of water across several loads.
