I have a vacuum system that works off the pool circulation pump; It won't pick up leaves or bugs, and tends to stir up quite a bit fine dirt back into the water. It also tends to repeat the pathway it is on, so I have to babysit it to cover the entire pool floor. It won't do walls at all. The PC10 picks up Everything! It only stirs up a little fine stuff, due to its powerful suction. Watching it climb the walls, cleaning to above the water line, was a joy! I put it in the water and went to lunch. The PC10 cleaned every square inch of the pool, without my help! The debris basket is super easy to clean- just rinse it under a hose or faucet. This PC10 was loaned to me to test out, so maybe I'll start a "Go-Fund-Me" so I can buy my own!
