I hate to contribute to the thread hijacking but I got my Poolbuster last week and it's great for spot cleaning. Wouldn't want to use it for the whole pool and it really needs a finer filter for sand (available for extra cost) but other than that it works wonderfully.

I usually put my Dolphin in at night but by the time morning rolls around a number of bugs have managed to crawl their way into my pool. I take 2 minutes with the buster and it looks great.
