ACIT - 5 Stars

I purchased this for a 14x33' pool and it works great. Completely cleans the pool and the waterline in one cycle. Easy to use and easy to clean.

Corry - 5 Stars

It is very light robot to carry in and out of the pool. I wanted a robot that clean the waterline around my pool. Anyway this robot climb up to the waterline and front brush is rubbing against slightly above the waterline. I am quite happy with it.

Purchased the product from Doheny pool supply. Purchased it to replace my old Kreepy Krauley that operated on the pools filtration system. The main reason I purchased the product was to reduce the burden on the main DE filtration system I was very disappointed to find out that the robotic cleaner does not really clean your pool. It picks up larger debris like leaves, worms, bugs, etc. but does not remove fine dirt. The fine dirt is blown through the fine screen back into the pool where the pool's main filtration system catches and removes the dirt. The water would become cloudy when I operated the Dolphin Advantage Ultra and is further evidence that the unit was merely re-suspending the fine dirt. It should referred to as a scrubber not a cleaner. That said, I still had to scrub the pools water line even after running the robot for 3-3hour cycles. I contacted product support at Doheny and their response was "I needed to run it longer". DUH!! Running it longer keeps the dirt suspended so that my main DE filter removes the dirt. They also want a 20% re-stocking fee to return the item. VERY DISAPPOINTED!!!!
