I wish I had some device which would clean my pool without any assistance. Ideally, this device would float in the pool and filter the water collecting leaves, seeds and other garbage in itself. It would have photo cells to work from the sun energy; the energy would be also accumulated so as the cleaner could be used in the rain or at night. All I'd need to do would be to clean the devise of the collected garbage.

I want to have some device which can automatically test the pool for its chemicals and then fix them accordingly. It could be placed near the filter in my pool and should have a timer.
