What some people don't seem to realize, is that a RV 360 with a brush head can actually be used to scrub with, without flushing. You can activate the brush only to scrub in your prespray, then pull the trigger and start flushing it out. Very effective.If you want a tool for residential, and decide on 175, at least go with rotovac
360. You can change the head for 175 effect. Light to carry up those steps.
But still, crb and rotovac is killer combo. I Do Not have a Dev., Board du jour, or not,
but I’m guessing that’s a tool to have.
