The thing with doing carpets as a bolt on is having to load up every time from scratch every time the dog rings. You can't with your damp van leave the gear on it, especially the electric portable. So you need to wheel it out, load it up, get your vac, , envirodri (or whatever you use for agitation) all of the wands, chems, attachments, sprayers, tools your air mover maybe and your bag of tricks. And you only need to forget one thing, as you do, to throw a spanner in. The lads using the Prowlers don't have that problem. They don't need to pre vac for starters coz of the heat they're getting. They don't need to empty the waste tank, coz it emptys as it sucks. They don't need to plug the vac side in downstairs and then the heater side in upstairs so as not to trip the switch. They mightened even need a turbo dryer as the sheer power would nearly leave them dry.
Its like the van mounted wc system, the quicker I can get water onto the glass the better. As opposed to the trollie dollies. I hate bringing the Advance into the customers home, its too noisy and awkward. I hate having to load it back into the van and then off back into the shed. I'm saving for a prowler.
