My 175 never leaves the shop. I use it for scrubbing rugs, that's it. My 15 inch
crb gets used constantly in homes and on commercial. It's lighter, scrubs well and goes up and down much easier than the 175. For me, the 2 must haves are a
crb and a Rotovac with brush head. The rv brush head is more aggressive than the
crb in my opinion. I have a small commercial job next week for an old property management customer. Carpets haven't been done for over 5 years. The Rotovac xl with brush head will be my tool or choice. If you can imagine what a 175 would be like if it also flushed and vacuumed, that's what the rv does.
