Review on 🛁 Upgraded 7.4V Cordless Electric Spin Scrubber for Bathroom with 5 Replaceable Cleaning Brush Heads and Extension Handle - Powerful Shower Scrubber for Tub, Tile, Shower, Kitchen by Alyssa Grinager

My wife got it to clean the shower which is tiled with granite. It did its job well, but it wasn't the miracle tool she was hoping for. The device itself looks well made and is comfortable to hold, but you really need two hands as it slips away if you don't. She used it without extension because it was easier to use. This meant she had to bend down to do the floor in the shower, and even with an extension cord she would have done so. The head recommended for flat surfaces is only 4 inches wide and had to be held in one spot for a while to clear the area. As a result, she took more time with the tool than with a sponge with a scraper on one side. The sponge also had the advantage over the brush of retaining the detergent while the brush did not. She uses cleaning bubbles, which tend to dissipate shortly after spraying. The sponge will absorb the cleaner and keep the surface damp, but the brush will not. The corner brush did a good job on corners and where the walls meet the floor. Given the smaller surface area, the brush worked quite well. The manual only mentioned the appointment of three brushes. GRP surfaces, such as bathtubs or shower stalls, but with granite tiles this doesn't work any better or faster than with a sponge.
