Water Tech Blue Diamond Pool Cleaner is a great choice for any in-ground pool, quickly scrubbing clean your entire pool without your having to lift a finger. Its on-board computer learns the most efficient way to clean your in-ground pool, resulting in cleaning speeds of about an hour, making it the fastest robotic cleaner made by Water Tech. Its rotating PVA scrubber has more than enough muscle to break loose any dirt, algae, and other debris that can accumulate on pool surfaces, while lasting twice as long as traditional brushes. Climbing pool walls, inclines and even pool steps is no problem thanks to its tank tracks, which virtually eliminate slipping that can lengthen cleaning times. Best of all, Blue Diamond Pool Cleaner is made by Water Tech, an industry innovator for over 40 years, allowing you to buy with confidence.
