At the rental house I'm in, the owner had an Aquabot in the (inoperable) hot tub. He said it didn't work very well, but I decided to fire it up anyway. It seemed to work ok, then I looked at the instructions and saw the part about emptying the filter bag. The filter bag and filter bracket were in the hot tub too, so I installed those and let it do it's thing. Wow, it works so much better with that on it!
This really makes me want to go to work on the allegedly inoperable hot tub.
