A genuinely useful stand-in for a full washer if you lack hookups, but expect real noise and a hand-fill routine, not a plumbed-in appliance.

Overview
A twin-tub portable washer with an 18lb wash tub and an 8lb spin tub that run at the same time, built for apartments, dorms, RVs, or anywhere without hookups. Total rated capacity is 26lbs across both tubs.
Costway's own spec sheet is upfront that the spin cycle only gets clothes to about 90 percent dry, with line drying still needed to finish. Reviewers largely confirm that tradeoff is worth it for the space saved, though the unit runs loud enough that apartment neighbors may notice.
- 26lb combined capacity (18lb wash / 8lb spin)
- Soft, standard, and drain modes
- Built-in drain pump plus 51-inch hose
- Transparent lid for monitoring cycles
Who it's for
Fits renters or RV owners without washer-dryer hookups who are willing to hand-fill the tub and finish drying on a line. Not a good match for anyone in thin-walled housing who needs a quiet machine, or who wants a fully automated fill-and-drain cycle.
What buyers say
From Amazon customer reviews.
Reviewers who lack in-unit hookups say it performs close to a full-size washer, with the spin cycle in particular praised for leaving clothes nearly dry. Common complaints are noise loud enough to carry to neighbors, zippered or long items balling up unless separated, and one owner reporting the motor failed after roughly 14 months of use.
