I see someone has a post on Rick G's forum suggesting the challenger T&G brushes don't work really well. Just wondering what you folks that use them think. I just recently ordered mine... at $35 it's certainly money well spent if they work well.

Grant, I like mine. I have no basis for comparison though with other brushes. I agree that for $35 they are well worth their price. Very easy to put on and off and they scrub very well I think. I sure wouldn't want to have to switch pad drivers just to clean some grout unless that process was made easier somehow.

I have a competitors machine and they also offer additional weights for tile & grout. Have tried it without the weight and results were mediocre at best. The additional weight made all the difference.
