Quick Answer

Yes, you can absolutely vacuum a pool without a skimmer. There are four reliable methods: using a dedicated suction line port, connecting a manual vacuum with garden hose suction, employing a submersible pump system, or using a robotic cleaner. Each method has specific steps and equipment requirements.

Method 1: Using a Dedicated Suction Line

Many pools have a dedicated vacuum port or suction line separate from the skimmer system. This is the most common alternative method.

1. Locate the dedicated suction port, usually found on the pool wall near the bottom or on the pool deck
2. Remove the port cover by unscrewing it counterclockwise
3. Attach your vacuum hose to the vacuum head and connect the telescopic pole
4. Prime the vacuum hose by holding it against a return jet until water fills the entire length
5. Quickly move the primed hose end to the suction port and insert firmly
6. Turn on your pool pump to create suction
7. Begin vacuuming in overlapping strokes, moving slowly to avoid stirring up debris
8. Monitor the pump basket and empty as needed during cleaning

Method 2: Manual Vacuum with Garden Hose

This method creates suction using a garden hose and venturi effect, perfect when no suction ports are available.

1. Purchase a garden hose vacuum attachment (venturi-style vacuum head)
2. Connect your garden hose to the attachment following manufacturer instructions
3. Attach the vacuum head to your telescopic pole
4. Turn on the water supply to full pressure to create suction through the venturi effect
5. Lower the vacuum head into the pool and begin cleaning
6. Move systematically across the pool bottom, allowing the suction to pull debris into the collection bag
7. Empty the debris bag frequently to maintain optimal suction
8. Monitor water level as this method adds water while cleaning

Method 3: Submersible Pump System

A submersible pump can create powerful suction for thorough pool cleaning without any pool plumbing connections.

1. Select an appropriate submersible pump (minimum 1/3 HP recommended for pools)
2. Connect a standard pool vacuum hose to the pump's intake
3. Attach the vacuum head to the other end of the hose
4. Lower the pump into the deep end of your pool
5. Connect the pump's discharge hose to drain away from the pool area
6. Plug in the pump (ensure GFCI protection) and verify suction at the vacuum head
7. Begin vacuuming methodically, working from shallow to deep areas
8. Monitor the discharge to ensure proper drainage away from the pool
9. Check the pump's intake screen periodically and clean if clogged

Method 4: Robotic Pool Cleaner

Robotic cleaners operate independently without any connection to your pool's circulation system.

1. Choose a robotic cleaner appropriate for your pool size and surface type
2. Charge the unit fully according to manufacturer specifications
3. Remove any large debris manually before deploying the robot
4. Lower the robotic cleaner into the pool at the shallow end
5. Allow it to sink and begin its programmed cleaning cycle
6. Let the unit run for the recommended cycle time (typically 2-3 hours)
7. Remove the robot and clean its filter cartridge or debris bag
8. Store the unit in a shaded, dry location between uses

Important Considerations and Tips

Safety Warning: When using electrical equipment near water, always ensure proper GFCI protection and never handle electrical connections with wet hands.

Pump Basket Maintenance

Regardless of method chosen, monitor your pool pump's strainer basket closely during vacuuming. Heavy debris loads can clog the basket quickly, reducing suction and potentially damaging your pump motor. Turn off the pump and clean the basket whenever suction decreases noticeably.

Water Level Management

Some methods (like garden hose vacuum) add water while others (submersible pump) remove water. Monitor your pool's water level throughout the process and adjust as necessary to maintain proper skimmer and return jet function.

Debris Management Strategy

For heavily contaminated pools, consider removing large debris manually with a leaf rake before vacuuming. This prevents clogging and improves cleaning efficiency regardless of the vacuum method used.

Troubleshooting Common Issues

If you experience poor suction, check all connections for air leaks, ensure hoses aren't kinked, and verify that strainer baskets are clean. For garden hose methods, confirm adequate water pressure at the source.

When vacuum heads won't stay on the pool bottom, the suction may be too strong. Partially close any valve in the suction line or reduce pump speed if using a variable speed pump.
