Muriel Gatlin - 5 Stars

Works better than any other robotic cleaner I’ve owned.

Mike_Fla - 5 Stars

This bad boy vacuums like crazy. Climbs the walls and stairs like nobody’s business. Highly recommended

GK - 1 Stars

Used this 5 times in a couple of months. It worked but small collection bins don't pick up reasonable size leaves, etc. Then died just after the three month return warranty expired! So I'm out $2K. Horrible poorly written instructions don't explain how the control unit works. Do not buy!!!

Don - 5 Stars

Our pool is 35' wide by 75' long. We do drop it in every other night and it does a great job keeping up.

ALB - 5 Stars

The company has been so helpful and it’s a great product for our neighborhood pool!
