Does what it says on the tin
Excellent scrubber for what I used it for. Floor Tiles in a 40sqm kitchen with tile stain remover. The green bristles were just soft enough it wouldn't harm the finish on the tiles, but if you want to scrub outdoor patio furniture, tables, etc. It's probably best to go with the one level up on bristle hardness. The 4ah battery I have from my other ryobi tools lasted a very long while, as the gearing is low enough it doesn't drag on the motor with the green brush. the harder brushes would consume more power.
