Interesting looking machine. Of course we had nothing like this in the US. Reminds me a little of the Thermax, but not nearly as bulky. Thermax started out as a hot water extraction carpet cleaner (they invented the process), and a very good one. But then they decided they could fill the recovery tank with water, add some cheap generic attachments, and sell it as a water filtration vacuum. Most of their sales force are disaffected former Rainbow dealers because the sales pitch, if not the machine, is similar. What does this Hoover use to collect the dirt?
