I don't know about the other brands, but I've used the Barwalt system for about three years now, and I like it. The sponges last a good while if you clean them after every use, and the bucket holds about 4 1/2 gallons. The whole setup includes the bucket, a large sponge and handle, a smaller sponge and handle, and a scrubber pad, and it costs around $110.

Actually Randy, it is the same sponge from a few years ago. It was a Rubi, that I got from Prosol. It was 11 bucks for the sponge, but how often to you get a few years out of a sponge. Now, I only do the final rinse with this sponge. I do the main wash with the Not So GOod sponge.

Gee .... thats a good sponge. Don't suppose you remember the product number of it eh?

Are we talking about the grout system? At least thats what we've been calling it. If it's the same thing make sure you spend the extra money for the metal rollers. Wayyyy nice and you can put some pressure on it to get that extra water out.
