I would stay away from Hoover. I have a two year old Steamvac that works great, but the hose broke recently and you can't get parts in Canada. The hose is 42 bucks and I have to throw away the unit because I have no way to get it in Canada.
It sucks because it is a good unit and I am fully willing to repair it and continue using it.
Also make sure you don't get fooled by the use of the word 'Steam'. The steam vac does not steam anything. It sprays hot water onto the surface and vacuums it up. The water is only as hot as you put it in the reservoir. The unit does not heat or evaporate it. All these home units are the same. Only large industrial units actually use steam. The difference is noticably, but since you will probably use your steamvac more often, you carpets and furniture always look good. And you can clean up nasty spills immediately.
