If robot vacuums are what keep your home looking fine day-to-day, a wet & dry cleaner is what deals with the real messes. In this video I tested the UWANT D600 through the stuff that usually exposes weak machines: mixed debris like cat litter + crumbs + hair, thick sauces that love to smear, and big liquid spills that robot vacs either avoid or choke on. What surprised me is how consistently it lifts mess instead of pushing it forward—debris gets pulled in as the roller passes, and liquids recover fast so the floor doesn’t stay soaked. The other big problem in this category is maintenance and smell. The D600’s self-cleaning base is the reason I call it underrated: it runs a four-stage cycle with hot water washing (up to around 200°F), electrolyzed deep cleaning, UVC sterilization, and hot-air drying with periodic roller turning so it dries evenly. After the cycle the roller feels dry to the touch, which matters a lot for preventing that “wet vacuum funk.” I also cover daily-use stuff you actually feel: strong edge cleaning along walls, going flat to reach under furniture (about 12 cm height), and a supported handle design that makes longer sessions less annoying. I also briefly show the HOTO PixelDrive screwdriver I’ve been using at my desk for builds and fixes.
