Meet WaterGuru.

The only smart poolside device that automatically tests and treats pool water—every day.

This ingenious device works great.

"Over the past 20 years we encountered several water disasters that cost us thousands of dollars to repair including recently emptying and refilling the pool. We installed WaterGuru to ensure our pool water is in perfect conditions every single day. This ingenious device works great. I just wish it was invented years ago… "

WaterGuru doesn’t just skim the surface.

It fits on top of your pool skimmer to monitor pH and chlorine with a patented sensor. Then it treats your pool for you by automatically dispensing the right amount of balancing agents.

Safe, clean water is a system of checks and balances.



WaterGuru automatically maintains daily pH and chlorine levels to keep your pool from losing its balance. And precise water balance means your pool stays consistently clean, clear and safe.
