The Basic Process for Cleaning an Intex Pool

Vacuuming an Intex pool means using a pool vacuum to remove debris from the bottom and sides without draining the water. Most Intex pools use a manual vacuum system that connects to your pool's filtration system or a separate pump. The vacuum head sits on a pole, a hose runs from the head to either your filter pump or a dedicated vacuum pump, and you push the head across the pool floor like you would a household vacuum.

The process takes 20 to 45 minutes depending on pool size and how much debris has settled. You do not need to drain the pool, and you can vacuum while the pool is in use—though it works better when swimmers are out. The key is connecting the hose correctly so water and debris flow toward the filter or waste line, not back into the pool.

Key Takeaways

  • Intex pools use a manual vacuum head on a pole connected by hose to either the filter pump intake or a separate vacuum pump.
  • You must prime the hose by filling it with water before starting so air does not break the suction.
  • Push the vacuum head slowly across the pool floor in overlapping rows, working from the deep end toward the shallow end.
  • Check your filter pressure during vacuuming and backwash if it rises more than 8 to 10 pounds per square inch above the starting pressure.
  • Empty the pump basket and rinse the filter after vacuuming to prevent clogs and maintain water flow.

What You Need Before You Start

Gather these items before you begin: a pool vacuum head (usually 14 to 18 inches wide for Intex pools), a vacuum pole that extends to 8 or 10 feet, a vacuum hose that fits your pool's intake port, and either a filter pump already running or a separate vacuum pump. Most Intex pools come with a filter pump that has a skimmer basket and a main drain intake—either one can connect the vacuum hose.

Check that all connections are hand-tight and the hose has no cracks or holes. A small leak in the hose will kill your suction and waste time. If you are using a separate vacuum pump (not the pool's filter pump), make sure it is plugged in and ready to run. Have a bucket or waste line ready if your pump has a backwash valve—debris will need somewhere to go.

Priming the Hose So Suction Works

Before you connect the hose to the pump intake, you must fill it with water to remove the air inside. Air in the hose breaks the seal and kills suction. Lay the hose on the pool deck, submerge one end in the pool, and let water flow through it until it comes out the other end. This takes 30 seconds to a minute depending on hose length.

Once the hose is full of water, quickly connect the end without the vacuum head to the pump intake port—either the skimmer intake or the main drain intake on your Intex filter pump. Do this while the hose is still wet so water seals the connection. If air gets back into the hose during connection, you will lose suction and have to prime again. Some people cover the intake end with their hand while connecting to keep air out.

Connecting to Your Intex Filter Pump

Most Intex pools have a filter pump with two intake points: the skimmer basket (the floating basket that catches leaves) and the main drain (the intake at the pool bottom). You can connect the vacuum hose to either one, but the main drain gives stronger suction because it pulls from the lowest point in the pool.

To connect to the main drain, locate the intake valve on the side of your filter pump housing—it usually has a threaded port. Screw the hose connector onto this port by hand until it is snug. Do not over-tighten or you may crack the plastic fitting. If you are connecting to the skimmer, remove the skimmer basket, insert the hose connector into the opening, and find it with the collar or clip that came with your vacuum kit. Turn on the filter pump and listen for suction—you should hear a slight hum and feel the vacuum head pull toward the pool floor when you place it in the water.

Vacuuming the Pool Floor in the Right Pattern

Place the vacuum head on the pool floor at the deep end. Push it slowly across the bottom in straight, overlapping rows—like mowing a lawn. Move at about one foot per second so the head has time to pick up debris. Overlap each pass by about 6 inches so you do not miss strips of the floor.

Work from the deep end toward the shallow end. This way, any debris you stir up will naturally flow toward the intake. If you vacuum from shallow to deep, you push debris away from the suction. When you reach the shallow end, lift the head out of the water, reposition it at the deep end, and start another row. The entire floor should take 20 to 45 minutes depending on pool size and debris load.

If the vacuum head loses suction mid-pool, stop and check the hose for kinks or the pump basket for clogs. A full basket will block water flow and kill suction. Empty it and resume. Do not drag the hose across sharp pool edges or rough concrete—it will puncture and leak.

Monitoring Filter Pressure and Backwashing

If your Intex filter pump has a pressure gauge on top, watch it while you vacuum. The pressure will rise as debris collects in the filter. When it climbs 8 to 10 pounds per square inch above where it started, stop vacuuming and backwash the filter. Backwashing reverses water flow through the filter to flush out trapped debris.

To backwash, turn off the pump, locate the multiport valve on top of the filter tank, and turn the handle to the "Backwash" position. Turn the pump back on and run it for 30 to 60 seconds until the water in the sight glass (the clear tube on the valve) runs clear. Then turn off the pump, switch the valve back to "Filter," and resume vacuuming. If your Intex pump does not have a multiport valve, you may need to empty the pump basket by hand instead—unscrew the basket housing, dump the debris, rinse the basket, and reinstall it.

Cleaning Up After Vacuuming

Once you finish vacuuming, turn off the pump and disconnect the hose from the intake port. Drain the hose by holding one end up and letting water run out into a bucket or back into the pool. Rinse the vacuum head and pole with fresh water to remove chlorine residue, which can degrade plastic over time.

Empty the pump basket one more time and rinse it thoroughly. A basket clogged with debris will reduce water flow and put strain on the pump motor. Hang the hose in a coil in a shaded spot to dry—do not leave it kinked in the sun, as UV light and heat will crack the plastic. Store the vacuum head and pole indoors or under a cover. If you leave them in direct sun for weeks, they will become brittle and crack.

Frequently Asked Questions

Why does my vacuum lose suction halfway through?

The pump basket is full of debris. Turn off the pump, unscrew the basket housing on the side of the filter tank, empty the basket into a trash can, rinse it, and reinstall it. Suction should return when ready. If it does not, check the hose for kinks or holes—a leak will kill suction even with a clean basket.

Can I vacuum while people are swimming?

You can, but it works better when the pool is empty. Swimmers will stir up debris and make it harder for the vacuum to pick it up. If you must vacuum during use, ask swimmers to stay in the shallow end and avoid the area you are cleaning.

What if my Intex pool does not have a main drain?

Connect the hose to the skimmer intake instead. Remove the skimmer basket, insert the hose connector, and find it. Suction will be slightly weaker than using a main drain, but it will still work. You may need to vacuum more slowly to give the head time to pick up debris.

How often should I vacuum my Intex pool?

Vacuum once a week during swimming season if the pool is in a yard with trees or heavy use. If the pool is in a clean area with light use, once every two weeks is usually enough. Vacuum more often if you see visible debris on the floor or if the water looks cloudy.

Can I use a robotic pool vacuum in an Intex pool?

Some robotic vacuums are designed for Intex pools, but they are not the same as manual vacuums. Robotic models are cordless, move on their own, and cost more upfront. Manual vacuums are cheaper and give you more control, but require more work. Either type will clean the pool—it depends on your budget and how much effort you want to spend.
