Very pleased with this machine, I've used it on all the carpets throughout the house and im very pleased with the results, my carpets come up lovely and I'm shocked at how dirty the water is that comes out of the carpets, even my living room carpet which has only been down for 7 months and we are a no shoes in the house kind of people and the dirt it lifted out is amazing. Definitely recommend this product and the larger tank is worth it less water changes/refills
