Review on Electric Spin Scrubber 360 Cordless Tub and Tile Scrubber: Upgraded Power and 4 Replaceable Scrubber Brush Heads for Effortless Cleaning of Bathroom, Floor, Wall, Kitchen, Tub, and Tile with Extension Arm by Faith Miller

Works great. I was worried it wouldn't be strong enough as some heads have softer bristles. Don't worry because he started walking on that tiled floor right away. LOVE IT. If you charge it up and don't use it right away, it will hold a charge for a few days later. It also has a handy charge indicator. Love the softer curved head for the shower glass, the hard flat for the bottom and the pointed one for the corners. Excellent purchase.
