Why it's worth it
The TUYU is a lightweight cordless scrubber with a stainless handle that extends from 26 to 45 inches and a motor with a low and a high setting. It's fully sealed to IPX7, so you can rinse the whole thing under the tap when you're done.
Two speeds matter more than one fast speed. The low setting runs around 350 RPM and the high setting around 450 RPM. Use low on shower glass, chrome, and an acrylic tub, where a stiff brush at full speed can leave fine scratches you'll notice later. Save the high setting for the ring around a porcelain tub or scale on a shower floor. Single-speed scrubbers force you to manage that with pressure alone, which is harder than it sounds.
The handle is the part you'll appreciate on day one. It telescopes from 26 inches down to a stubby length for sinks and out to 45 inches for the top of a shower wall. Owners consistently describe the same before-and-after: they used to clean the tub on their knees, and now they don't. If you have a bad back or a bad knee, this is the whole reason to own one of these.
