Also looking into this , few choices there is the RX20e from Hydramaster which also does hard floors,there is the Drimaster from Hydramaster too which looks good,there is something called a rotovac which i just looked at , they are so confident that you will love it they give you a free trial for a week. And prochem do a Powerglide and another bigger machine .
Would also like some info on thease machines as looking into getting something myself
