We bought the dual power pet advance carpet cleaner and with a maximum of 6 uses roughly every 3-4 months the machines belt has snapped and the belt tensioner has melted. We have been told this part cannot be replaced and the whole unit must be replaced instead. The burning smell is so strong and quite frankly a hazard and the machine only has a 1 year warranty. This is our second Vax product which has piled in early. Avoid and spend more money on a better unit.
