Propeller vs Pressure Boosted Pool Cleaners

What pressure-side pool cleaners are

A pressure-side pool cleaner is a type of automatic cleaner that connects to the pool's return line, using the force of water pushed through it to move and collect debris. Unlike suction-side cleaners that rely on the pool pump's suction, pressure-side cleaners are powered by water pressure. This pressure can come from the main pool pump or a separate booster pump, depending on the model.

On a listing, the title often says 'pressure-side' or 'pressure cleaner'. This tells you the cleaner is designed to work with water pressure, not suction. The listing may also mention 'booster pump required' or 'works with existing pump', which indicates how the cleaner gets its power. Understanding this helps you match the cleaner to your pool's equipment. For a broader comparison of cleaner types, see the best pool cleaner guide.

Propeller-driven cleaners: how they work

Propeller-driven pressure cleaners use the water flow from the pool pump to spin an internal propeller. This propeller drives the cleaner's wheels or tracks, moving it across the pool floor and up walls. The water that powers the propeller also carries debris into the cleaner's bag or canister.

On a listing, you might see 'propeller' or 'turbine' in the title or description. This indicates the cleaner uses water flow to generate motion. Propeller-driven models typically work with the pool's existing pump, so they don't require a separate booster pump. However, they need sufficient water flow to operate effectively, which the listing may specify as a minimum flow rate. If you're considering a suction-side alternative, check the best suction pool cleaner guide.

Pressure-boosted cleaners: the role of a booster pump

Pressure-boosted cleaners are a type of pressure-side cleaner that requires a dedicated booster pump to increase water pressure. The booster pump provides a higher, more consistent water flow than the main pool pump alone, which helps the cleaner move more effectively and pick up debris. These cleaners often have a separate hose and connect to a dedicated pressure line.

On a listing, 'booster pump required' or 'pressure-boosted' signals that you need this additional equipment. The booster pump is a separate unit that is installed near the pool's pump system. If you don't already have one, you'll need to factor that into your purchase. The listing may also mention 'booster pump included' or 'sold separately', so check the details carefully. For inground pools, the best inground pool cleaner guide can help you compare options.

Comparing propulsion methods on listings

When comparing propeller-driven and pressure-boosted cleaners, the key difference is how they generate propulsion. Propeller-driven models rely on the main pump's water flow, while pressure-boosted models use a booster pump for higher pressure. This affects the cleaner's movement, debris collection, and the equipment you need.

On a listing, look for terms like 'propeller', 'turbine', 'booster pump', and 'water flow'. These words tell you how the cleaner is powered. A listing that says 'works with your pool pump' suggests a propeller-driven model, while 'requires booster pump' indicates a pressure-boosted one. Also, check the 'hose' and 'connections' sections to see if the cleaner needs a dedicated pressure line. For above ground pools, the best above ground pool cleaner guide offers specific advice.

What to look for on a listing

When reading a pressure-side cleaner listing, focus on the propulsion details. Look for the type of drive (propeller or booster), the pump requirements, and the hose setup. The listing may state 'booster pump required' or 'uses existing pump', which is crucial for compatibility with your pool's equipment.

Also, check the 'debris bag' or 'canister' size, as this affects how much debris the cleaner can hold. The 'hose length' and 'float' details matter for maneuverability. If the listing doesn't specify the propulsion method, it may be a generic pressure-side cleaner, so you'll need to read the maker's page for more details. The best pool cleaner guide covers all types and can help you decide.

Matching the cleaner to your pool setup

The right pressure-side cleaner depends on your pool's pump system. If you have a single-speed pool pump and no booster pump, a propeller-driven cleaner that works with the existing pump might be a simpler choice. If you have a variable-speed pump or are willing to install a booster pump, a pressure-boosted cleaner could be an option.

On the listing, check the 'pump requirements' section to see if the cleaner needs a booster pump or a minimum flow rate. The ENERGY STAR page on pool pumps explains that pool pumps re-circulate water through a filter, and that filtration requires only half the flow rate of running a pool cleaner. This means your pump's flow rate matters for pressure-side cleaners. If you're unsure, contact the maker or a pool professional for guidance.

What to pick for your situation

Questions

What does 'propeller-driven' mean on a pool cleaner listing?

It means the cleaner uses water flow from the pool pump to spin a propeller, which drives the cleaner forward. This type typically works with the existing pump and doesn't need a booster pump.

What does 'pressure-boosted' mean on a pool cleaner listing?

It means the cleaner requires a booster pump to increase water pressure for movement and debris collection. The booster pump provides higher pressure than the main pool pump alone.

Do pressure-side cleaners need a booster pump?

Not all of them. Propeller-driven models can work with the main pump's flow, while pressure-boosted models require a dedicated booster pump. Check the listing for 'booster pump required' or 'works with existing pump'.

How do you know if a pressure cleaner will work with your pool pump?

Look for the pump requirements on the listing, such as minimum flow rate or booster pump needs. The ENERGY STAR page on pool pumps explains that pool pumps re-circulate water, and that filtration requires half the flow rate of running a cleaner. If unsure, contact the maker.

What is the difference between propeller-driven and pressure-boosted cleaners?

Propeller-driven cleaners use the main pump's water flow to spin a propeller, while pressure-boosted cleaners use a booster pump for higher pressure. This affects the equipment needed and how the cleaner moves.
