Homitt Electric Spin Scrubber Power Brush With Adjustable Extension Arm and 3 Brush Heads For an upgrade on the model I have, I'm eying this Homitt Electric Spin Scrubber Power Brush With Adjustable Extension Arm and 3 Brush Heads ($70) next. Because it extends longer (up to 42 inches), it would be easier to reach the upper walls of my shower without stretching my arms and to clean the floor without even bending down. Win-win.
