I was thinking on buying one of these aswell in the beginning. I tried it out and it really gets rid 100% rid of the odour IF you stay within a certain circle around the suction! It is very quite running. looks nice... But i am only wondering if i could actually manage keeping my liquid, wipes, brush and customers fingers all the time in this circle where the suction is strong enough. I think aswell that it is quite expensive when you look on other more industrial websites you can find the same type of unite but for a lower price. It is actually the carbon filter that makes that unit so effective. Im still thinking about it aswell....
