Nitro Wall Scrubber
The Nitro Wall Scrubber manufactured by SmartPool Inc. is the best cleaner I have ever owned. My inground pool is 22' X 44" with an 8.5' deep end. The surface is vinyl and the shape is free- form.
The Nitro Wall Scrubber completely cleaned my pool in under 2 hours. It was able to get into areas that historically had to be cleaned manually. I also noticed that the cleaner never got stuck! The filter bag is very large and captures sand, leaves, acorns and anything else it passes by. I must mention the weight of the cleaner as well. This cleaner is so light that my wife can remove it from the pool very easily. (This was a major problem with our previous robotic cleaner.)
As far as repairing the Nitro, it can't be easier. All you need is a screwdriver and you can replace anything inside the unit from the pump motor to the drive motors, or anything else in under 20 minutes!
All in all, we love our Nitro Wall Scrubber and would highly recommend buying it for your inground pool. It's very affordable especially when compared to all other robotic cleaner on the market today!
