Before You Start: Prerequisites & Tools
Sequence matters in pool vacuuming. If you skip these steps, you’ll stir up sediment you were trying to remove, or vacuum into a filter that’s already at capacity — neither gets you a clean pool.
Step one is always to skim and brush before you vacuum. Use a leaf net to clear the surface, then brush the walls and floor to knock contaminants into the water column or settle them on the bottom where the vacuum can reach them. Skipping this step means you’re vacuuming a moving target.
Check your filter pressure gauge. If it reads 8–10 PSI higher than your normal “clean” baseline, backwash or clean the filter before you vacuum. A dirty filter at the start means you’ll clog it even faster mid-session.
Required tools for manual vacuuming:
- Vacuum head
- Telescopic pole (long enough to reach the deepest point of your pool)
- Vacuum hose
- Vacuum plate (optional — used to connect hose to skimmer without losing suction)

Filter vs. Waste: The Most Important Decision
Before you connect a single hose, you need to make a decision: are you vacuuming to Filter or to Waste? This one choice determines whether your session succeeds or makes your water worse.
Algae = Always Vacuum to Waste
Sending dead algae into your filter lets spores recolonize the media and return to the pool. Bypass completely — even if it means refilling the pool afterward.
Use the Filter setting for routine, light-debris vacuuming — dirt, sand, leaves that have sunk. Water goes through the filter media and back to the pool, which is ideal for normal maintenance.
Use the Waste setting whenever you’re dealing with algae, pool floc (the white cloudy sediment from flocculation treatments), or heavy post-storm debris. The Waste setting bypasses the filter entirely and sends dirty water out of the system rather than through the media. Yes, your pool level drops — but the alternative is clogging your filter immediately and sending algae spores straight back into the water.
Important: Never Move the Valve While the Pump is Running
Rotating a multiport valve handle while the pump is running destroys the internal spider gasket — a $20 part that requires complete filter disassembly to replace. Always turn the pump off first, make your valve adjustment, then restart.
Manual Vacuuming: Step-by-Step Technique
Manual vacuuming gives you the most control over where you clean and how thoroughly — which is why it’s the preferred method for post-algae treatment cleanup and anything the automatic cleaners can’t handle. Follow these steps in order.
Skim & Brush First
Use a leaf net to remove floating debris, then brush all walls and the floor to move settled dirt into the water column. Wait 10–15 minutes for the water to settle before vacuuming. Skipping this step means you’ll vacuum up half the debris and leave the rest stirred up in suspension.
Assemble the Vacuum Head and Hose
Attach the vacuum head to your telescopic pole. Connect one end of the vacuum hose to the vacuum head. Make sure the connection is tight — any loose fitting will let air in and break your suction during the session.
Prime the Hose (Critical)
Lower the vacuum assembly into the pool. Hold the open end of the hose against a return jet and let pool water fill the hose completely until all air bubbles stop. Only then connect the open end to the skimmer or suction port. This creates the siphon that powers the vacuum. If you skip hose priming, you’ll suck air into the pump — which causes overheating, seal failure, and potentially $500+ in pump damage.
Set Your Filter Valve (Before Turning On)
With the pump off, set the multiport valve to Filter or Waste depending on the debris type. See the brand-specific section below for exact valve positions. Turn the pump back on once the valve is set.
Vacuum with Slow, Overlapping Strokes
Move the vacuum head across the floor using long, slow, overlapping strokes — like mowing a lawn. Moving too fast stirs the debris into suspension rather than collecting it, making your water cloudier and forcing you to re-treat with chemicals. Work methodically from one end to the other.
Monitor Your Pressure Gauge
If the pressure gauge climbs 8–10 PSI above your baseline while vacuuming, the filter is getting loaded. Stop the vacuum, backwash or clean the filter, and then continue. Ignoring a rising pressure gauge forces the pump to work harder than it was designed to and reduces suction at the vacuum head.
Disconnect and Store the Hose Properly
Turn off the pump before disconnecting the hose from the skimmer. Hang the hose in a straight line or large loops — never coil it tightly. Coiled hoses develop “memory,” creating kinks and curves that cause the vacuum to skip over sections of the pool floor on your next use.

Pool Net (Leaf Rake)
Step one before every vacuum session. Clearing floating debris first prevents your vacuum hose from clogging and protects the pump basket. Deep-bag design holds a full session’s worth of leaves without needing constant emptying.
Brand-Specific Valve Settings
Each filter brand has its own valve positions, pressure baselines, and model-specific requirements. Using the wrong setting — even briefly — can damage the filter media or cause a complete blockage. Use the section for your equipment below.
Valve positions use the Hayward VariFlo multiport handle:
- FILTER — Use for routine, light-debris vacuuming. Water goes through filter media and returns to pool.
- WASTE — Use for algae, pool floc, or heavy post-storm debris. Water bypasses the filter completely and exits the system.
Model-specific notes:
- Pro-Grid (DE filter): Ensure the filter is pre-coated with D.E. powder before beginning any vacuum session in Filter mode. Without a fresh D.E. “cake” on the grids, fine particles pass directly through and return to the pool. Never run the Pro-Grid for more than 3 minutes without D.E. on the grids.
- SwimClear (Cartridge): Vacuum directly into the filter in Filter mode. Watch the pressure gauge — clean the cartridge if pressure rises 7–10 PSI above your baseline, even mid-session.
- S-Series (Sand): Switch to Waste for heavy spring or post-winter cleanups to avoid clogging the sand bed. Backwash after every significant vacuum session.
- FILTER — Standard maintenance vacuuming.
- WASTE — Bypass for heavy debris or pool level reduction.
Model-specific notes:
- Triton II (Sand): Monitor your flow rate during vacuuming. If flow decreases more than 30% from your clean baseline, stop and backwash — the sand bed is loaded.
- Clean & Clear Plus (Cartridge): If you have a variable-speed pump, record the Original Pump RPM and its corresponding startup pressure before your first session. This is your baseline for determining when the cartridge needs cleaning. Pressure thresholds mean nothing without a recorded baseline.
- FNS Plus (DE): Always recharge with the correct D.E. dosage after backwashing before resuming vacuum in Filter mode.
- FILTER — Normal vacuuming operation.
- WASTE — Vacuum directly to waste line for algae or heavy debris.
Model-specific pressure thresholds:
- SF/SFTM (Sand): Clean (backwash) when pressure increases 10–12 PSI above your original starting pressure. Jandy sand filters have a slightly higher tolerance than Hayward before requiring a backwash.
- DEV (DE): Never operate for more than 3 minutes without D.E. powder on the filter grids. Vacuuming without a proper D.E. “cake” will damage the grids — replacement grids run $150–$300 depending on the model.
- CL/CV (Cartridge): Vacuum in Filter mode; monitor gauge and clean cartridge when pressure rises 8–10 PSI over baseline.
Suction-Side Automatic Cleaners
Suction-side cleaners connect to your skimmer or a dedicated suction port and draw power from your existing pump. They’re simpler and less expensive than pressure-side units, but they send all debris through your filter — so filter condition matters more with these cleaners than any other type.
The most common calibration issue with suction-side cleaners is incorrect flow. Too little flow and the cleaner barely moves; too much and it races around erratically and misses sections. Each brand has a specific target speed you should verify during the first deployment.
| Brand / Model | Flow Target | How to Check |
|---|---|---|
| Hayward Navigator / PoolVac | Flow gauge disk between MIN and MAX | Observe the built-in flow gauge indicator on the cleaner body |
| Hayward TracVac | 11–14 RPM (large right wheel) | Count wheel rotations per minute after 5 minutes in the pool |
| Pentair Rebel / Warrior | 11–13 RPM | Count wheel rotations per minute |
| Pentair ‘Lil Rebel | 18–26 RPM | Count wheel rotations per minute; higher RPM target for smaller unit |
| Zodiac MX6 / MX8 | 10 rotations in 20–25 seconds | Time 10 wheel rotations with a stopwatch after deployment. 26–50 seconds = increase flow. |
Pro Tip
If your suction-side cleaner is circling in one area or climbing the walls repeatedly instead of covering the floor, the most common cause is too much flow. Install or adjust the regulator valve at the skimmer or suction port to reduce flow until the cleaner pattern normalizes.
Pressure-Side Automatic Cleaners
Pressure-side cleaners use water pressure — typically from a dedicated booster pump — to propel themselves around the pool and collect debris into an onboard bag rather than routing it through your main filter. This makes them gentler on your filtration system and effective at collecting larger debris like leaves.
Most pressure-side cleaners require a separate 3/4 HP booster pump operating between 28–32 PSI. Without the correct pressure, the cleaner either won’t move at all or will cycle erratically. To verify RPM, mark one wheel with a marker, submerge the cleaner just below the surface with the pump running, and count rotations for exactly one minute. Compare to your model’s target range.
| Brand / Model | Target RPM | Notes |
|---|---|---|
| Polaris 280 / 380 | 28–32 RPM | Industry-standard range for Polaris pressure units |
| Polaris 3900 Sport | 30–36 RPM | Slightly higher target due to three-wheel drive design |
| Pentair RACER (with sweep hose) | 31–33 RPM | Sweep hose slightly slows the unit; account for this when adjusting |
| Pentair RACER (without sweep hose) | 33–36 RPM | Higher RPM target without the drag from the sweep hose |
| Pentair Legend II | 25–32 RPM | Wider acceptable range; adjust to lower end for carpeted pools |
| Kreepy Krauly Platinum | 34–38 RPM | Higher target range; confirm booster pressure is within 28–32 PSI |
Robotic Pool Cleaners
Robotic cleaners are self-contained units powered by low-voltage electricity plugged into a GFCI outlet. They operate completely independently from your pool’s filtration system — they have their own motor, pump, and filter canister. This means they don’t pull suction from your pump and don’t send debris through your filter.
They’re the easiest to use, but they require specific deployment and storage procedures that many pool owners get wrong — and the mistakes can void your warranty or burn out the motor entirely.
Critical: Turn Off Your Main Filter First
For models like the Hayward AquaVac 250, turn off the filtration system at least 15 minutes before deploying the robot. Running the main pump while a robotic cleaner is in the pool can interfere with the robot’s navigation and suction — and for some models, creates competing water currents that prevent wall coverage.
How to properly deploy a robotic cleaner:
Submerge and Purge Air
Hold the robot vertically and rock it side-to-side as you lower it into the water. This releases all trapped air from the internal chambers. Continue rocking until air bubbles stop rising. If air remains inside, the robot will float or fail to climb walls — and will spend the entire cleaning cycle covering only the center of the pool floor.
Allow Time for Pool Mapping
Most modern robots spend an initial period calculating the size and layout of your pool before beginning systematic coverage. The exact time varies by model: the Hayward SharkVac requires the first 10 minutes per the manual, while the Hayward TigerShark may take up to 30 minutes to measure pool configuration before climbing the walls fully. Polaris robots (including the 9550) also confirm pool parameters during an approximately 10-minute initial window. This is normal — do not pull the cleaner out thinking it’s not working.
Select the Right Cycle Length
Most robots offer a Quick Clean (1.5 hours) for light maintenance and a Full Clean or Deep Clean (2.5–3 hours) for thorough coverage. Use the Quick Clean for weekly maintenance and the Full Clean after storms, heavy use, or if the pool has been left for more than two weeks.
Remove and Rinse Immediately After the Cycle
Do not leave the robot in the pool after the cycle ends. Remove it using the handle — never by the floating cable, which will damage the internal waterproof seals and electrical connections. Rinse the filter canister with fresh water immediately. Debris that dries inside the canister hardens and restricts airflow in future cycles, straining the motor over time.
Brand-specific indicator lights and error codes:
- Code 1: Pump short-circuit — contact service
- Code 2: Right traction motor short-circuit — contact service
- Code 3: Left traction motor short-circuit — contact service
The 9550 Sport features a Lift System where the cleaner drives forward and up the wall to the waterline for easier removal without bending over.
The LED indicator blinks blue during normal operation. If the light pattern changes, consult the manual — the Prowler 920/930 does not display numeric error codes but uses different blink patterns to indicate fault conditions.
On the Prowler 830, pull out only one float on the handle before deploying. Using both floats makes the unit harder to turn effectively in the pool and reduces wall coverage.
The AquaVac 250 uses a battery charge indicator rather than an error code system:
- 4 green lights: Full charge — up to 120 minutes of runtime
- Last light blinking: 10 minutes of usage remaining — retrieve and recharge
Always ensure the unit is fully charged before deployment. Running out of battery mid-cycle means incomplete coverage and the robot sinks to the bottom without the motor to hold it at the cleaning position.
Filter-Type Considerations
Your filter type determines what you can and can’t do during a vacuum session. The rules differ significantly between sand, D.E., and cartridge filters.
| Filter Type | Vacuum to Waste? | Backwash/Clean Trigger | Replacement Interval |
|---|---|---|---|
| Sand | Yes — via multiport valve | 8–10 PSI above baseline | Sand replacement: 3–5 years |
| D.E. (Diatomaceous Earth) | Yes — with fresh D.E. recharge after | 8–10 PSI above baseline | Grid inspection annually; replacement varies |
| Cartridge | Not standard — requires custom bypass valve | 7–10 PSI above baseline | Chemical clean annually; replace every 2–5 years |
Sand filters are the most forgiving for heavy-debris vacuuming. They can handle significant dirt loads when you vacuum to Waste, and backwashing takes only a few minutes. If pressure stays high after backwashing, the sand may be “mud-balled” — clumped together by oils and fine particles — requiring a chemical cleaner or full sand replacement.
D.E. filters trap particles as small as 3–5 microns (the finest filtration of the three types) but require careful handling. Always recharge with fresh D.E. after backwashing, before continuing vacuum operations. Running even 3 minutes without a D.E. cake on the grids will damage them.
Cartridge filters are the most common in newer residential pools. They cannot vacuum to Waste without a custom-installed bypass valve. This means algae treatment must involve the full filter cycle — which is why ensuring the cartridge is clean before you start an algae cleanup is critical. Plan to clean the cartridge mid-session for severe algae blooms.
How Often Should You Vacuum?
The standard recommendation is to vacuum at least once per week during swim season, combined with weekly brushing. But the actual trigger should be based on what you’re seeing — not just the calendar.
Signs you need to vacuum now:
- Visible dirt, sand, or dust on the pool floor (yellow or green “dust” is often early algae)
- Cloudy or hazy water that doesn’t clear after chemical treatment
- Reduced water flow from return jets (30% reduction indicates a loaded filter)
- Pressure gauge reading 8–10 PSI above your clean baseline
✅ Seasonal Vacuuming Schedule
-
Weekly (swim season): Manual or suction-side clean, brush walls, check filter pressure -
After storms or heavy rain: Vacuum to Waste to remove phosphates and metals before they enter filter -
Spring opening: Manual vacuum to Waste for heavy debris before restarting normal filtration -
Summer (above 85°F): Increase pump run time to 12+ hours/day; more frequent debris checks -
Winter (freeze climates): Drain all water from equipment; store cleaners in shaded, dry area to prevent UV damage
What happens if you skip vacuuming for weeks or months? Within a few weeks, a neglected pool begins turning green. Within a few months, algae blooms and phosphate buildup can cause permanent staining on plaster surfaces, vinyl liner shrinkage, and plaster etching — damage that costs hundreds to thousands to repair and isn’t covered under any warranty.
Common Mistakes & What They Cost
These are the mistakes pool owners make most often — with the real-world cost attached to each one so you understand why the correct technique matters.
| Mistake | Consequence | Repair Cost |
|---|---|---|
| Vacuuming algae into the filter | Algae spores recolonize the media and return to the pool. Causes recurring green water and can choke the filter immediately. | $100–$250+ (repeated chemical treatments + filter cleaning) |
| Not priming the hose | Air sucked into the pump causes loss of prime, overheating, melted shaft seals, warped baskets, and damaged PVC fittings. | $100–$150 (seal rebuild) to $500+ (full pump replacement) |
| Lifting robotic cleaner by the cable | Damages internal electrical connections and waterproof seals; water intrusion destroys the motor. | Voids warranty; variable parts cost |
| Running robot out of water | Immediate and irreversible motor seal damage — the motor relies on water for cooling. | Voids warranty; full motor replacement |
| Leaving robot in pool permanently | Chronic chlorine exposure oxidizes metal parts and deteriorates plastic and rubber components, shortening lifespan significantly. | Early unit replacement ($500–$1,500+) |
| Coiling hoses for storage | Hose develops “memory” — kinks and curves that cause the vacuum head to skip areas on the next use. | $50–$150 (new hose sections) |
| Vacuuming too fast | Stirs debris into suspension instead of collecting it; results in cloudier water and additional chemical cost. | Extra chemicals + repeat session |
Safety Warnings: What to Never Do
Pool vacuuming involves pump systems, electrical equipment, and pressure vessels. These aren’t hypothetical hazards — they’ve caused deaths. Read these before your next session.
Suction Entrapment Hazard
Powerful pumps can trap hair, loose clothing, or limbs against drains and vacuum ports. Always install ANSI-compliant safety drain covers on dedicated suction lines. Never use a vacuum head connected to the main drain as the suction source without a safety vacuum release system (SVRS).
Pressure Vessel Rupture Risk
Filter systems can rupture or “pop their lids” if started with closed valves, or if the filter clamp is not properly seated. This has caused fatal injuries. Always open the return-side valve before starting the pump and visually confirm the filter clamp is fully engaged before pressurizing the system.
Electrical Shock — Robotic Cleaners
Never handle a robotic cleaner or its power supply while it is plugged in or with wet hands. Always unplug the power supply before retrieving the robot. Robotic cleaners must be plugged into a GFCI-protected outlet only.
The Complete NEVER List:
- NEVER rotate the multiport valve while the pump is running — destroys the spider gasket
- NEVER vacuum algae or pool floc into the filter — always vacuum to Waste
- NEVER leave a robotic cleaner in the pool during chemical shock treatments
- NEVER mix pool chemicals together — can produce toxic gas or explosive reactions
- NEVER allow the pump to run dry — warps the housing and melts the shaft seal
- NEVER lift a robotic cleaner by its floating cable — use the handle only
- NEVER run a D.E. filter without D.E. powder on the grids — even 3 minutes damages them
Frequently Asked Questions
Should I vacuum my pool to Filter or Waste when dealing with algae?
Always vacuum algae to Waste. Sending dead algae spores through your filter media allows them to recolonize and return to the pool, causing the green water to come back within days. Set your multiport valve to Waste before starting, accept that your water level will drop, and refill afterward — it’s the only way to clear an algae bloom permanently.
How often should I vacuum my pool?
Vacuum at least once per week during swim season, combined with weekly wall brushing. Increase frequency after storms or periods of heavy use. The real signal is visual: if you can see dirt or “dust” on the floor, or if your water is hazy despite balanced chemistry, it’s time to vacuum regardless of your schedule.
Why does my suction-side cleaner keep circling in one spot?
Circling behavior in suction-side cleaners is almost always caused by excessive flow. Too much suction makes the cleaner “stick” to areas with higher suction and creates erratic patterns. Adjust the regulator valve at the skimmer or install one on the suction port to reduce flow until the cleaner moves in a systematic pattern across the floor and walls.
Can I leave my robotic pool cleaner in the pool overnight?
No. Leaving a robotic cleaner in the pool exposes it to sustained chlorine concentrations that oxidize metal components and degrade rubber and plastic seals over time. Remove and rinse the robot after every cycle. Staying in the pool during a shock treatment (high chlorine) is especially harmful and can void your warranty on most brands.
What size robotic cleaner do I need for my pool?
Match the robot’s cable length to your pool’s longest dimension, with at least 10 feet of extra cable. For example, a 50-foot pool requires a robot with at least a 60-foot cable. A cable that’s too short means the robot can’t reach the far end of the pool and will only partially clean it despite running a full cycle.
Why does my robotic cleaner float instead of sink when I put it in the pool?
Trapped air inside the unit is preventing it from sinking. Hold the robot vertically and rock it side-to-side as you lower it into the water to release all trapped air from the internal chambers. Continue until air bubbles stop rising from the unit. If air remains, the robot will float or only cover the pool floor without climbing the walls.
How long should I run my pump each day?
Run your pump long enough to turn over the entire pool volume at least once daily — for most residential pools this means 8–12 hours per day. In summer when temperatures exceed 85°F, increase run time to 12 or more hours because higher temperatures accelerate chlorine consumption and algae growth. Use off-peak hours (overnight) to reduce electricity costs.
