I was concerned at first that the clean water/solution tank was small, but it's prefect for my needs. I was able to clean up 4 puppy-pee spots perfectly, and still have half the solution left over that I loaded in. I like that it is really compact so stores easily, that the cord and hose wind up nice and tight, and it can fit in a small space. Cleaning the dirty water tank was a breeze and took 2 minutes. Would recommend for spills and spot cleaning. Very handy and affordable.
