No he is not.
He now has the opportunity to set himself apart from ALL of his competitors, LM or HWSE, by offering a higher specification clean that could encompass both systems, dry vac, pre-spray, agitate, HWSE followed by dry padding. This isn't about technicalities, it's about marketing and producing results that have your customer believe that they can't get what you do anywhere else, do that and you'll have customers coming back to you.
