Review: Works brilliantly. I have just received this item so am reporting only on first usage. A few hours to charge then put it in our pool - easy to do with hook supplied (which fits a 'normal' pool pole). Was set for random motion over the floor of our flat, tiled pool. The pool had quite a lot of fine (filter) sand on he bottom, which we'd never been able to get out, plus a few leaves, some quite big. I didn't check how long the battery lasted but certainly well over an hour. Easy to get the device out again - parked at the side of the pool: the buoyancy makes it light to raise to the surface, when you can then grab the handle to pull it out of the water - easier than I had expected. The revelation was when we opened the robot up. The pool bottom looked clean, but the fine debris had not been that easy to see; however inside the robot was far more fine debris, mainly very fine sand but also other gunge, than I had expected, plus the leaves. (Easy to open up the robot, via a couple of clips). The detachable filter itself looked quite clean, with all the debris in the bottom of the robot. Only negative is that the bottom has lots of nooks and crannies (a lot to do with keeping the base strong, I suspect) where the debris sits, so a bit fiddly to wash out with a garden hose - but this is trivial. Really impressed, and I trust that longer term my views won't change. (Bought with next day delivery, which compensated for a previously ordered device which appears tohave got lost in transit.) My early opinion is that this device is great value for money and works extremely well, removing debris from the very finest to large leaves.
