I have. On a scale of 1 - 10 I would rate it at 8. I liked the way it worked. The only problem I had was that the suction cups would come off every week or so. I have read many posts saying they are no good becuase the rotating motion will quit working after a short time but I had mine for like 6 months. I gave it away but it still was working good.
Pure junk. I've only heard of a few success stories with them and a whole bunch of bad. I had one and the sweep feature worked for 24 hours and was noisey when it did. I took it apart and cleaned it like everyone recommended and it worked for exactly one half of a sweep. I e-mailed the manufacturer and got no response from them.
maxijets are my favorite. I have had a power sweep for well over a year and it still works fine. My only complaints are that the suction cups do not stick at all so I have to rest it on a piece of rock. The rotating mechanism also clogs up a lot but it is easy to clean. I have to take it apart and rinse it with hot water at least once a week, but it does work.
