Rotovac BH most aggressive I should've turned psi down from using the zipper and devastator wands.
It lift jet streaks, the zipper left faint jet streaks nothing like the Rotovac and there's was no jet steaks from the devastator wand.
That's said the really trashed room needed the RE, hell it all did, but my
CRB and wand did awesome.
It's hard to explain you use a wand then try something new and it's crazy how it's just seams to clean faster and better. The Devastator wand.
Looking forward to zipping some commercial carpets after CRBing
