Help! My Polaris Pool Cleaner Stopped Moving!

When I post videos on the Swim University YouTube Channel, I encourage viewers to ask me questions about their pool problems on Facebook. I got this question, and I figured I’d answer here so you can benefit if you have the same issue.

Hi! I have a question. My Polaris is not working. My booster pump had quit working, so I replaced it. There is water going to the Polaris, but it is not moving. What do I need to look for to see what is wrong?

Thanks for your question, Kim!

There are five things you can troubleshoot when your Polaris pool cleaner seems slow or stops moving all together.

5 Reasons Your Polaris Pool Cleaner Stopped Moving

I’m going to assume that the pressure coming from your return line, where you hook up the Polaris cleaner If you click this link and make a purchase, we earn a commission at no additional cost to you. , is working fine. If you’re not getting strong pressure, it could either be your pump, filter, or booster pump.

If this is the case, it might be a broken booster pump, which you’ll have to replace, or as simple as air in your system.

1. Check The Quick Disconnect

The quick disconnect If you click this link and make a purchase, we earn a commission at no additional cost to you. is the piece you use to attach the Polaris hose to the return jet. Inside this piece, there’s a screen to catch debris coming from your filter so that it doesn’t enter the cleaner. Make sure this is clean and free of any sand or debris. A clogged screen could be your problem.

Also, make sure the piece isn’t broken. A broken quick disconnect will leak water preventing the right amount of pressure to power the pool cleaner. If it’s broken, you’ll need to replace it.

The back-up valve If you click this link and make a purchase, we earn a commission at no additional cost to you. is a large white device located on the Polaris Hose.

4. Check The Belts

There are drive belts inside the Polaris that allow the wheels to turn. Sometimes these belts break and will stop the cleaner in its tracks.

An easy way to tell if this is your problem is by lifting the cleaner off the bottom of the pool and seeing if all the wheels are turning. If the back-up valve is working, and the tail is waving back and forth, but the wheels aren’t turning, open up the cleaner and look for the belts. They may be missing if they’ve snapped.
