How to Clean a Polaris Pool Cleaner Tailsweep
Turn off the pump, remove the Polaris tailsweep per the manual, and rinse away grit and debris. If it still drags or sprays poorly, inspect related wear or clogging.

A dirty Polaris pool cleaner tailsweep is best put right in the simplest way: shut down the pump, take the part out as the manual says and give it a good rinse with fresh water to get rid of any hair, grit or debris. Should that not be enough to get things moving normally again, then you are likely looking at some wear, a clog or another kind of pressure-side trouble.
The function of the tailsweep
On a Polaris pressure-side unit, the tailsweep is what channels water and detritus behind the cleaner. It is a small component but one that will gather buildup from the hose, the walls or the bottom of the pool. You can expect to find your share of leaves, fine dirt, scale or even a sticky film left by algae or an unbalanced pool. Then there is hair or stringy material.
Do not assume the cleaner has given up just because the sweep is soiled. More often than not, a sluggish unit is down to a clogged hose, something in the filter or valve, or poor flow from the booster pump.
Safe cleaning procedure
Because the process for removal can differ from one Polaris model to the next, it is wise to have the cleaner’s manual on hand.
1. Make sure the pump is off before going near the skimmer or the cleaner. 2. If your model permits, lift the unit from the water, being careful to stay clear of any suction that is still in operation. 3. Take out the tailsweep per the instructions. 4. A thorough rinse with clean water will handle the loose matter; for anything more tenacious, a soft cloth or gloved hand should do. 5. Put it back in place and verify it has free movement before you fire up the system.
Wear the appropriate PPE when dealing with sharp grit or biofilm and never put a hand into a live suction opening.
Further troubleshooting
If the cleaner is still acting up or leaving a trail of debris, run through the rest of the Polaris system methodically. With the pump off, see if the baskets in the skimmer or pump are clogged. Examine the hose for kinks or a loose connection. Have a look at the nozzle and tailsweep for any blockage or cracks. If your setup has a booster pump and valve assembly, make sure they are in order. You may also notice the unit going in circles, which is usually a sign of a flow problem. As a rule of thumb, maintaining clean filtration and skimmers will help the circulation system along.
Time to replace or call in a professional?
There is only so much a cleaning can do. Engage a qualified pool pro if you find the tailsweep is worn or cracked, or if the unit is still not behaving after you have done your due diligence. The same goes if you think there is a leak, a problem with the valve or booster pump, or damage to the fittings and wall connector.
And if you are in any doubt as to whether your particular Polaris has a removable tailsweep or a different kind of sweep hose, leave it to the experts. Do not attempt any electrical work or structural alterations. For safety’s sake, turn the pump off to access the skimmer basket and heed the chemical labels. If the water is unsafe or there is an electrical fault, do not swim.
