Debated between the medium soft green or the coarse red and ultimately chose the green, deciding that I was unwilling to risk damaging the surface I spent over a month preparing, stenciling and preserving 2 years ago. The green was an excellent choice in scrubbing out accumulated dirt and mold in the zillion crevices of a textured concrete pad, yet with zero damage to the poly or paint. That painted surface has returned to its bright color as though it were new again. I used the same attachment for the front porch (similarly painted and poly'd) with identical results and the attachment still looks nearly new, so despite being used on over 200sqft of concrete, that single attachment held up perfectly with no problems whatsoever. In a couple spots when I pressed down too hard, the bit would spin and skip. Just stop, retighten and then resume with less pressure. What I really needed to do in those spots was change the angle so the bristles could reach the bottom of the divots in the concrete rather than simply pressing harder. Also, incidentally, despite not being rated for carpet/upholstery, the green also did a magnificent job on a short fiber, densely piled entryway rug that I was going to throw out, but it cleaned up so well that it looks like new again. I'm really, really happy I bought this.

My daughters having potty regression, and her bedroom is very humid. This gave me the power to really clean the rug that trying by hand just wasn’t cutting. It looks and smells so much better now!I used it in both wall to wall carpet and a pink and white throw rug, no damage to either.

Handy to use for different cleaning jobs. It saves your arms, elbows and hands from heavy scrubbing.

Made cleaning carpet in the car very easy

Worked great on my foormats

I never thought I would use a power tool to clean the toilet but wow what difference in time and efficiency. Love these brushes.

It’s doing the job cleaning stuff,.

They work really good and stay attached to drill I would highly recommend
