Yeah, scrubs good. Leaves little bits inbeded in the carpet. Can be a bitch to vac out. Fiberpads ware out way faster then under a rotary.
In most cases its more then a PIA then its worth compared to other options
What are you trying to accomplish?
Just looking to scrub and run?
If you just want to scrub and run, Tuway's or Micro fibers, work better then cotton/glads with out falling apart. You can always use cottons or glades on the high traffic areas and the tuways or Micros on the bulk of the job.
Or work over heavy traffic areas better?
Hit those high traffic areas with a
CRB or even you carpet brush on you 175 then mop up with a glad.
