I inherited 2 of them....long story. My DSisIL recently moved back to this area and purchased an old house from an even older lady. The house needed spruced up before she moved in. I brought over that machine after she pulled out the old linoleum and rugs and I used it to clean the wood floors that were underneath, thinking that we would have to refinish them when we were done. That machine stripped off centuries of crud and old wax off those floor to reveal the hardwood floors. After a light sanding and a fresh coat of the stuff you cover wood with (I can't remember what we used)she has The most beautiful floors. I am hooked on using it now. It works particularly well on greasy buildup in the kitchen and beats scrubbing any day without any harsh chemicals.
