The only reason I got the valve was because I had no confidence in our shop to actually fix the scrubber. Even though I had no experience in the maintenance of this equipment, the instillation was really straightforward and with a little work, I was able to replace the old one within 15-20 minutes.
These are great vacuums. Lighter than the past ones we have had and the suction power is better. These are our everyday go to vacuums in our school district
