Speaking of which,
@TConway does you wand work on a 2-3stage portable? I have a big hotel job with small rooms and some tight areas... A swivel wand would be the best... My 13" Zipper is doing a fantastic job on them, but having to move all the furniture in every room sucks... Good thing is all the carpets get protection applied after..
How tall is the head on the Devpro? Same as a PCTI? I'm using plastic saw horses to lift the end of the beds because my Zipper top where the hose goes doesn't fit under the bed..
