www.rawlins.co.ukthis Uk company supply an excellent water filtration vac at a very attractive price and it's easy to use - some others are not - and i can reccomend it from personal use.
As part of the ' healthy homes ' concept, there have been a number of these machines around for some time, with some selling for as much as fifteen hundred pounds.
the hydro vac is less than two hundred pounds and will do what the others do.
if you want to get into the Allergen control market, I believe this is an essential tool, as it's the only vac system that truly encapsulates allergens, mites. etc and you can show your client the evidence.........you can olso add a fragrance which will remain in the atmosphere long after the machine has been used.
Obviously, I'm a fan.....it also does what a well known vac company claims, but fails to deliver.......you get max power 100% of the time.
