Bought this with many expectations, Never imagined it would help clean bathroom tiles, but at least hoped for kitchen tiles and top-side of kitchen shelves (wardrobe), where dust accumulates a lot. This is not useful for cleaning long accumulated dust from any surface. I tried this on plywood, tiles, granite, bathroom floor and wall tiles etc. But this is not effective in removing dust from any of these.
After this, we tried scrubber - both manual, and as an attachment to driller. It worked better
than this brush. So I did not find any use of this brush, and returned this.
