A Cleaner Pool.
A Simpler Routine.

Flat-bottomed above-ground pools. Lower the HTH™ Above-Ground Pool Robotic Cleaner into the water wheels-down so the shell never touches your vinyl liner. This above-ground pool cleaner cleans the pool floor, so a smooth, even bottom gives you the best results. Deep wrinkles or objects on the floor can stop it, since the cleaner is not designed to climb obstacles.

No. The HTH™ Above-Ground Pool Robotic Cleaner filters pool water on its own as it works, with no hose, no pump and no cord to connect. Keep the two separate: run your pool filter on its own schedule, and run the cordless pool robot when the filter is off.

The HTH™ Replacement Filter for the Above-Ground Pool Robotic Cleaner is the pool vacuum filter your cleaner was engineered around. It matches the original suction and debris pickup, down to the housing dimensions. Drop it in, close the lid, done. Search results for pool robot filters fill with aftermarket copies, and quality varies widely between them. Filters clog fastest when your cleaner works the hardest, right after a storm or a week of heavy pollen, so keep a spare on hand. Between changes, rinse the pool vacuum filter and reinstall it.

Nothing is wrong. Every HTH™ Above-Ground Pool Robotic Cleaner is water-tested before it leaves the factory, then cleaned and dried before packing. A few drops can stay behind. Wipe it down and get started.

Start with a charge. Plug in the charger and watch the LED. A pulsing red light means the battery in the rechargeable pool cleaner is charging, so let it charge fully before you try again. If nothing happens at all with the charger connected, contact customer service and we will take it from there.

That pause is on purpose. The above-ground pool vacuum robot holds off on starting its pump until it confirms it is fully in the water, and the sensors take a moment to calibrate. Give it a few seconds and it will get to work.

Three quick checks. Look at the wheels and suction ports for trapped debris. Check the pool floor for deep wrinkles or an uneven base. Then look underneath the HTH™ Above-Ground Pool Robotic Cleaner for anything caught there. The above-ground pool cleaner is not designed to climb obstacles, so clearing the floor usually gets it moving again.

Usually it is the pool vacuum filter. Pull the filter screen, rinse it and reinstall it. If performance is still down, charge the battery fully, since a low charge slows the cordless pool robot too. Clean the filter after every use and you will rarely see this.

Keep the port dry and it will not. Wipe the charging pin on the rechargeable pool vacuum after every use and dry it with a paper towel or cotton swab. Press the silicone plug back in tightly after each charge so water cannot reach the port.

Give the shock time to work first. Your pool filter needs to run to circulate shock through the water, and the above-ground pool vacuum robot should not run while the filter is running. Shock in the evening and let your filter run overnight. Run the HTH™ Above-Ground Pool Robotic Cleaner the next day, once the filter cycle is done. Clean both filter screens when you finish.

Floors and seats in your pool or spa. The HTH™ Cordless Handheld Pool & Spa Vacuum picks up settled debris, so use it for routine maintenance rather than dirt that has built up over a long stretch. This hot tub vacuum is not a surface skimmer, and it is not built for large, hard or sharp objects.

Wait until everyone is out. The HTH™ Cordless Handheld Pool & Spa Vacuum creates suction, so keep hair, fingers and loose clothing away from the openings while it runs. Take extra care around steps.

Rinse the spa vacuum with fresh water after every use, and skip the detergent. Dry the body and accessories with a cloth, then store it indoors at room temperature, away from sunlight, heat, rain and pool chemicals. Never leave the rechargeable pool vacuum sitting in the water or plugged in. Charge it fully before you put it away for the season, and top it off at least once every three months.

The HTH™ Replacement Filter for the Cordless Handheld Pool & Spa Vacuum is built to this vacuum's suction spec, not adapted from a universal size. It seats correctly the first time, with no trimming and no gaps for debris to slip past. Aftermarket filters vary in media and fit, and a loose one lets debris bypass the filter entirely. Rinse the spa vac filter under a hose after each clean and put it straight back in. Replace it when fine sand stays lodged in the media and rinsing stops bringing suction back, or any time the filter is damaged. Never run the vacuum without one.

Two things. Make sure the ON/OFF switch on the handheld pool vacuum is toggled fully into position until it clicks. Then shine a flashlight into the water outlet and look for anything caught in the impeller. If neither is the cause, the battery pack may need factory service.

The HTH™ Cordless Handheld Pool & Spa Vacuum needs to be fully underwater to pull suction. Submerge the whole body, including the indicator light and the water intake port. If the pool vacuum is fully under and still not pulling, check the brush suction opening for a large object blocking it.

Give the filter rack and dust box a clean. Debris left sitting is the usual cause. If the handheld pool vacuum is new, a faint plastic smell is normal and fades once it airs out.

First confirm the spa vacuum is switched on, then watch for the light at startup. Blue means you are good to go. If the light still does not come on, charge the HTH™ Cordless Handheld Pool & Spa Vacuum for no more than two hours and check again.

That is the automatic shutdown protection doing its job. The cordless pool vacuum turns itself off when it is not fully submerged. Keep the whole body underwater, including the indicator light and the water intake port, and it will keep running.

Vacuum it out. Sand settles into the footwell and along the seats where a skimmer never reaches, and draining the tub costs you a full fill of water and a full round of chemicals. Use the HTH™ Cordless Handheld Pool & Spa Vacuum with the floor brush attached. Submerge the whole hot tub vacuum, including the indicator light and the water intake port, then work slowly across the floor and along each seat. The brush lifts settled sand and the filter captures it, so you can clean a hot tub without draining it. Empty and rinse the filter when you finish.

Lift the filter out of the HTH™ Above-Ground Pool Robotic Cleaner and rinse both layers with a garden hose until the water runs clear. The pool vacuum filter is built to rinse and go back in, so cleaning it is part of the routine rather than a replacement.

After every run is the habit worth keeping. Debris left in the mesh dries in place and gets harder to rinse out. Rinsing the auto pool vacuum filter while it is still wet takes a minute at the hose.

Replace it when rinsing no longer brings the mesh back to clean, or when either layer is torn or misshapen. Keeping a spare HTH™ replacement filter on hand means a worn filter does not cost you a week mid-season.

A loaded filter is the first thing to check. When the mesh is packed, water cannot move through it and the cleaner stops collecting. Rinse the filter, reseat it, then run the robot again before looking at anything else.

The HTH™ Above-Ground Pool Robotic Cleaner filter runs a 240-micron nylon mesh over an ultra-fine sponge. The mesh catches leaves and larger debris, the sponge takes the fine particles, so the two layers work as one pool vacuum with filter.

No. This replacement filter is made for the HTH™ Above-Ground Pool Robotic Cleaner and fits that cleaner only. Check the model before ordering above ground pool vacuum parts.

Yes. The filter is built to rinse clean with a garden hose and go back into the HTH™ Above-Ground Pool Robotic Cleaner. A replacement is for a filter that is worn or damaged, not for one that is simply dirty.

Micron is the measure of how fine the mesh openings are. The 240 micron layer is the outer nylon mesh on the HTH™ Above-Ground Pool Robotic Cleaner filter. Behind it sits an ultra-fine sponge that takes what the mesh lets through.

Genuine HTH™ replacement parts are sold through HTH™ Pools retailers. Match the part to your cleaner, since above ground pool vacuum replacement parts are built for a specific model rather than fitting across brands.

A spare keeps the above ground pool vacuum robot running while the first filter dries or if one gets damaged mid-season. Rinsed filters go back in wet, so a second filter is about having a backup, not about drying time.

A loaded filter is the usual cause. Fine debris packs the media until water cannot pass through it. Suction drops off from there. Pull the filter from the HTH™ Cordless Handheld Pool & Spa Vacuum, rinse it clean, then put it back.

Remove the filter from the HTH™ Cordless Handheld Pool & Spa Vacuum and rinse it with a garden hose until the water runs clear. The media is built to rinse clean for reuse, so this is routine care rather than a replacement.

Rinse it at the hose after each use, before the debris dries into the media. The HTH™ Cordless Handheld Pool & Spa Vacuum filter catches sand, silt and hair. All of it comes out easier wet than dry.

Replace it once rinsing stops restoring suction, or when the media is torn, flattened or will not seat properly. Until then the filter rinses clean and goes back in.

Fine-particle media that catches the sand, silt and hair a skimmer leaves behind. That is the debris the HTH™ Cordless Handheld Pool & Spa Vacuum is built for, in a hot tub or along a pool step.

No. The filter is made for the HTH™ Cordless Handheld Pool & Spa Vacuum and fits that model only. Match the part to your vacuum before ordering.

Yes. The filter rinses clean with a garden hose and goes back into the spa vacuum. Replace it when it is worn or damaged rather than when it is simply dirty.

When the filter is loaded, the finest debris passes rather than being held. Rinse the filter clean and the HTH™ Cordless Handheld Pool & Spa Vacuum goes back to catching sand, silt and hair.

After each use. Rinsing while the debris is still wet keeps the media clear, which is what keeps suction consistent from one clean to the next.

The filter is the part that wears with use, since it takes the sand, silt and hair every time you vacuum. Keeping a spare on hand means a worn filter does not stop the clean.
