Replacing a pressure-side pool cleaner with a robot: energy and upkeep
A pressure-side cleaner runs off the pool pump, and many need a booster pump too. Here two robots that carry their own motors show what a person takes on in power and upkeep when one replaces it.

Questions
What readers ask
Do these robots use less power than a pump-driven cleaner?
The robots carry their own supply: 120 W for the Dolphin, 150 W max for the Polaris, for runs of about two hours. No measured comparison with a pump-driven cleaner was found.
Does a robot mean turning the pool pump off?
A robot does not need the pump to clean. The pump still does the pool’s filtering.
Can a robot use the skimmer or suction line the old cleaner used?
No. Each robot plugs into its own power supply on a GFCI outlet, set 10 to 12 ft from the pool edge.
