Routine maintenance and cleaning
Vacuuming a pool
Vacuuming lifts what brushing and skimming leave on the floor. Choosing where that debris goes — the filter or waste — is the decision that matters.
Manual vacuuming connects a vacuum head and hose to a skimmer or dedicated vacuum point, using the pump’s suction. The hose has to be filled with water first, so the pump draws water rather than air. Slow, overlapping passes across the floor stop fine debris being stirred into the water.
Routine guides describe one part of regular pool care and how to do it properly.
Light debris can go through the filter as normal. Heavy loads — sand after a storm, dead algae after a green pool treatment, fine dust — are better sent straight to waste using the filter valve, so they do not clog the filter or pass back into the pool. Vacuuming to waste removes water, so the level is topped up afterwards.
The short version
Prime the hose first
A hose full of air can make the pump lose prime.
Filter or waste
Light debris to the filter; heavy sand, dust or algae to waste.
Slow passes
Fast movement stirs fine debris back into the water.
Step by step
Set up
Attach head and pole, lower the head and feed the hose in so it fills with water before connecting to the suction.
Vacuum
Work in overlapping lines from shallow to deep, watching the pump basket and pressure.
Finish
Return the valve to filter, top up the water level if you vacuumed to waste and clean the baskets.
Before you start
- 01
Empty the baskets
Full baskets reduce suction.
- 02
Check the water level
Especially before vacuuming to waste.
- 03
Brush first
Brushing lifts debris so vacuuming collects it.
Common questions
Why does the pump lose prime when I vacuum?
Usually air in the hose, a small leak in the hose or a water level too low for the skimmer.
When should I vacuum to waste?
For sand, heavy dust, dead algae or debris the filter cannot hold.
Can a cartridge filter vacuum to waste?
Many cartridge systems do not have a waste setting; a separate pump or careful filter cleaning is used instead.
