It works really well on grout. It does all the hard scrubbing for me. This tool is a work saver.

The hurricane spin scrubber is awesome. No backbreaking bending or getting on my knees. My shoulders, wrists and hands are grateful that i purchased this products.

This is supplied with ancient ni-cad batteries, which have long ago have been replaced by lithium-ion batteries in all power tools. It can run while plugged into an outlet. It now recharges without the lag.

Tried different outlets but still nothing. The light show reds for a couple of minutes, which means it is charging but then the light turns green. Media could not be loaded.

The battery/power is so bad that i couldn't get one shower stall done, let alone clean. Would barely get soap scum or dirt off. The batteries and connections are corroded. Put any pressure while scrubbing and it will stop.
