Designed to transform the tediousness of clothes washing into something that's at least a little more efficient, Twin Wash allows you to run simultaneous cleaning cycles. The general idea is that you can stash your bulky items up top and smaller, delicate items below with less time wasted. And since they are technically standalone units, they have separate water hookups, so the water that's cleaning your bright red towels in the upper machine won't mix with the water that's cleaning your white t-shirts in the lower one.
