The way a carpet should be cleaned depends primarily on what it’s made of. If it’s thick, polyester carpet, I use a tough brush and a towel. If it’s a wool rug, I’ll generally use a soft pad in lieu of a brush. If it’s cheap and flat, it really shouldn't be brushed at all. Synthetic carpets clean better than animal ones, and some spots and stains just don’t come out. It takes more time to properly clean some carpets, so I charge extra for wool to make sure I can take the time to do it right. The bottom line is, no matter what your carpet is made of, our system is made to handle it.
