I absolutely loved this machine after I shampood my carpets with ease, reloaded the tank with ease and changed the scrubber heads with ease, then came the bare floors.  For some reason it decided it had had enough of me and refused to start!  I tried everything and finally started shaking the thing and it finally came on!  This was the first day I had it.  Then it started smelling a faint odor of burning machinery, so now I will take it to a hoover repair place.  What a hassle!  I am not happy!
