Kind of clunky. It holds a LOT of water/solution. I want to know the ratio of water to cleaning solution, so that I don't have to fill it all the way. I don't need that much and would rather not store it with a nearly full tank. Operating was simple! Machine is quite loud, especially while using hand piece. Wear ear plugs. Easy to remove the dirty water, slightly more difficult to clean out the dirty water tank, as it is large so you need to use a kitchen sink or a sink with a lot of space. Overall a great vacuum! I was amazed at how dirty the water was from a small area of one-year old carpet.
