Using a pool vacuum
The process is straightforward: get the water ready, prime the hose and follow your manual to make the proper connections, then work the head in slow, overlapping sweeps over the floor of the pool. Do not open the skimmer area with the pump on, and be sure to stop if you notice any loss of suction or something that does not seem right.
Pre-vacuuming preparation
Some prep work will ensure the vacuum is collecting debris rather than just churning it around.
- Remove any floating leaves or insects.
- Give the walls, steps, ladders and floor a good brushing to dislodge dirt.
- Verify the water is at a level that allows the skimmer to function properly.
- If necessary, turn off the pump and clear out the skimmer basket and pump strainer.
Following this routine is good for maintenance and keeps the system from clogging. You may also find in some manufacturer literature a suggestion to brush sediment down to the bottom for easier pickup.
Setting up a manual vacuum
With a manual unit, you want the hose full of water before it goes on the suction side of the system; that way air is bled out and the suction will engage without trouble. While you should defer to the sequence in your equipment manual, the typical procedure is as follows:
1. Put together the pole, head and hose. 2. Get the head and hose completely under water. 3. Let the hose fill to expel the air. 4. Make the connection at the skimmer or vacuum plate as indicated in the manual. 5. See that the hose stays submerged to prevent the pump from drawing in air.
Never put your hands in an operating skimmer or fitting. If you are in any doubt about where to connect things, put it aside and consult the manual or a pool pro.
The proper way to move the head
You cannot rush it. Quick strokes will only agitate the dirt. A better approach is to be methodical:
- Begin at one end and cross the floor at a steady pace.
- Overlap your passes in the manner of mowing a lawn.
- Linger on areas with more debris.
- Re-brush and re-vacuum any stubborn spots.
This holds true for both inground and above-ground pools. Should the water become too cloudy, let the matter settle and come back to it.
Dealing with a stuck vacuum or poor suction
When a vacuum clings to the bottom or starts to pull air, there is likely a problem with the flow or setup. Run through these:
1. Is the pump on the correct setting for this job? 2. Is the hose primed and under water? 3. Have you checked the skimmer basket and strainer? 4. Look for kinks or a loose fit in the hose. 5. Listen for anything odd with the pump or weak circulation.
If a bit of cleaning does not restore the suction, or if you think there is a fault with the equipment, have a technician look at it. In the event of an electrical problem, do not use the pool.
Once you are done
Shut the pump off first before you go to the skimmer to put the hose away. After that, empty the baskets and give the filter a backwash or clean per the maker’s directions. Put the head, pole and hose in storage after a rinse and see how the water looks before anyone gets in. If the pool is still not up to standard despite a thorough job, you may be looking at a filtration or circulation issue that calls for professional eyes.
