Awesome For Cleaning Dirty Concrete
[[VIDEOID:22a8ddf995d93e5fad420e96ba460887]] We live in a high rise with a large outdoor balcony. We've been contained to clean it as we cant have the water draining down to another balcony. Bought this tool - incredible.  Comet, a little  water, drill away, clean with a towel - good as new. Highly recommend!!  I left a few dirty patches so you can see the different in the pictures.
