This is the 3rd robot pool cleaner I've owned and is by far the best and the cheapest! It efficiently cleans the floor of the pool and easily climbs the walls, stairs and ledge. It's much lighter than the others so it's much easier to manage into and out of the pool. Being cordless also helps a lot with handling the cleaner easily. I have 2 minor issues with it. A few times some larger leaves have locked open the flap to the basket, so when I took the cleaner out of the water, a lot of litter fell back into the pool. I now make sure to scoop out any larger leaves out of the pool before using the cleaner. The second issue is that you need to be prepared when wanting to use the cleaner. It takes about 2 hours to charge, so you either need to charge after you just used it, or be prepared to wait 2 hours before using it. A little bit of planning will help with your efficiency.
