I have one clean's decent without restrictor, not sure if its skip's around on gluedown with restrictor leaves carpet really dry. You could pre spray with encap juice use a rotary to scrub it in light rinse HWE then post bonnet and use fans.
PS I have a commmercial job next time I do it Ill use my drymaster. I like Environex Brush and bonnet cleaner works well as a pre spray on commercial. I have a quad jet PC wand I'll put Joe Bristors shear kit with 4 flow key on the back stroke only clean nice dry's fast no wick back.
Take the drymaster but have a back up plan!
