Received a replacement unit after the first one's pump broke and I was unable to find a replacement part. We've used it a few times now and it is cleaning really well. Kids spilled chocolate milk on carpet and didn't tell us for more than a day - they tried to hide it with a cloth and toys. It was dry when I discovered it. Took a few minutes to go back and forth but it is almost entirely gone now. So hoping that the pump lasts!
