I've used Wonderwash tubs since 2021. Am now on my fourth repurchase (fourth tub is a backup). I use the tub (along with a spinner) to wash an average of two loads per week of personal items and linens for work.
Heavily soiled work, workout clothing and linens are soaked for an hour, agitated, drained; but require a minimum of ten-twelve rinses before water drains clear. Less soiled clothing and linens require a brief presoak, wash and roughly eight rinses. I usually set it up for the day and work with one or two loads as I'm working out or doing housework.
More rinsing is absolutely required to get items clean, but I still love the product because it is compact, off-the-grid and still saves me money. I also love the new transparent design so I can see how clear the water is.
So long as I can continue to afford them, I will definitely be back for more.
