That's pretty impressive, 7 minutes for both sides???? How abrasive is the brush, notice some spattering in the pics, and what was the condition of the brush when you were done?
the brush is a little stiff so I don't use it on chrome, the brush holds up really well, the bristles spread open and it really works so well on so much it is pretty cool, carpets, I cleaned the bottom of our shop lawn mower in like 4 minutes. I jsut did the carpet on my stairs at home. I am going to scrub bath tub with it tomorow. I cleaned a filthy cooler with it today it lloked like new when i was done.
