The Blue Diamond Pro is an all-inclusive pool cleaning system. Other robotic cleaner manufacturers offer up to 7 different commercial cleaners, each with different accessories and add-ons. This makes choosing the perfect cleaner very difficult, an expensive risk to take by making the wrong choice. Water Tech Corp. knows cleaning a commercial pool poses a technical challenge, and is the only manufacturer to incorporate 21st century technological advances into a single universal commercial pool cleaner. The Blue Diamond Pro incorporates EVERY feature and option offered by other companies, along with an array of exclusive ones not available elsewhere, such as its Time Delay System that automatically commences cleaning several hours after a pool has closed, only after dirt and debris have settled on the floor and walls.
