Pump Speed and Booster Pump


Jun 28, 2020

I have a pressure side cleaner which requires a booster pump. My question is - does the speed of my normal pump matter? Will my cleaner work better if I increase the RPM speed of my pool pump when running the booster pump, or will that actually hurt performance? I'm thinking it's not useful to increase my pool pump speed since the booster goes directly in the line where the cleaner hose is attached.

No, I don't think so. But more importantly, see if you can find in the cleaner manual how one determines the cleaner's performance. Sometimes it's expressed as how fast its wheels are turning (revolutions or feet per minute sort of thing). Sometimes the cleaner comes with a little gauge to measure pressure or flow (my suction cleaner did, not sure about pressure cleaners). If the cleaner is performing correctly at the main pump speed you prefer to use, then you're good-to-go.

And @guinness is correct, most pressure cleaners need both pumps to be running, the booster is correctly named, as it is boosting the pressure supplied by the main pump to what the cleaner needs. Which is why I got rid of both my booster and my pressure-side vac, had the cleaner line replumbed to suction-side and installed a suction vac. Works the same, but I don't have to empty the a bag, no tail spraying my windows, and no extra pump.

Others here use robots, which require no pumps to be running.
