Overview
The Superday portable washer is an 18 pound twin tub machine, an 11.6 pound wash side and a 6.4 pound spin side, aimed at apartments, dorms, RVs and other spaces without a hookup for a full-size machine.
Superday's listing describes a water inlet system containing silver flakes that release silver ions during operation, a detail from the manufacturer rather than independent testing. Each tub runs on its own timer, with wash options for gentle, normal or drain and a spin timer that runs up to five minutes.
- 18lb total capacity (11.6lb wash + 6.4lb spin)
- Independent wash and spin timers
- Silver-ion water inlet per manufacturer
- Compact twin tub design
Who it's for
Works for anyone doing light to medium laundry loads in a small space, since the twin tub layout lets you spin one load while washing the next. Not a replacement for a full-size machine on heavier loads or for anyone who needs completely dry clothes straight out of the spin cycle.
What buyers say
From Amazon customer reviews.
Most reviewers describe the machine as quiet and stable, handling around ten loads without trouble and fitting into small spaces like a shower stall, closet corner or RV. Several note the spin cycle leaves clothes damp rather than dry, needing an overnight or few-hour air dry afterward, which matches the manufacturer's own guidance. One buyer wished the power cord were longer and the drain hose wider, and a different buyer reported a grinding noise developing by their second use, a contrast to the otherwise consistent praise for quiet operation.
Strengths and trade-offs
Drawn from this product's published specifications.
- Twin tubs let you wash and spin together
- Reviewers call it quiet and stable
- Compact enough for a shower stall or RV
- Clear cover lets you check the load
- Spin cycle leaves clothes damp, needs air-drying
- One unit developed a grinding noise quickly
- Cord and drain hose felt short to one buyer
Performance notes
Multiple reviewers describe the machine as quiet and stable through both the wash and spin cycles, with one buyer running about ten loads without issue. The spin tub does not fully dry clothes, matching the manufacturer's own note that items need roughly one to three hours of air drying afterward, something reviewers confirmed by finding clothes dry by morning. Draining works best into a bucket so the water flows out slowly rather than all at once.
