Personaly i cant fault it.
Had one for almost 15 months and not had any problems or issues. Apart from from both vacs and pump head going, but i have put close to 850 hours on it and use powdered detergents. And also just discovered the beauty of changing carbon brushes
Plus, the vacs and pumphead are the universal and would of worn out the same in any machine.
Suction seems to be great too, not just cos of the 3 vac's but also because of the round shaped waste tank.
Got other good wee features on it like a brake, which has come in handy many many times! Never thought i'd use it before.
Two major factors for me are the looks of it and the ease of mantiance. << Within 20 seconds you can have the whole thing open and staring at the vac motors without the need of tools!
Never changed a vac motor in my life before getting the airlfex but i was able to di it in around 40 minutes. Saves me £40 an hour +vat to a techian + over charged for parts..
And the looks, personaly i think this is important. Its what i call a "2nd type of cool" (first being functionality and performance) but you need to give that wow factor to customers and show you mean business! << sounds cheesy i know but i've hand many great comments from customers.
Customer service at cleansmart is second to none also.
