How Pool Cleaners Connect to Your Pump
Short answer: Pool cleaners connect to your pool equipment in one of three ways. A suction-side cleaner runs off the pool pump, pulling water through the cleaner as the pump draws from the skimmer or a dedicated suction line. A pressure-side cleaner connects to a return line and may need a separate booster pump. A robotic cleaner does not use the pump at all: it is powered by low-voltage electricity and collects debris in its built-in filters. Reading the listing tells you which type you are buying.
What a pump connection means in a cleaner listing
A pool cleaner listing names the connection type in one of three ways: suction-side, pressure-side, or robotic. Those words describe how the cleaner gets its water moving, and they are the first thing to read in a title. The connection type decides what the rest of the equipment pad must provide.
A suction-side cleaner uses the pool pump as its power source. A pressure-side cleaner uses water from a return line and may ask for a separate booster pump. A robotic cleaner is self-contained and does not tie into the pump. The site's comparison of cleaner types covers the shopping differences between the three.
The listing also states the intended pool type. A title for an above ground pool and a title for an inground pool each name their pool, and the words "fits" or "compatible with" in a cleaner listing are the seller's words, not a site claim. If the pool type is not stated, the listing is not complete for a buying decision.
- Suction-side: runs off the pool pump through a skimmer or a dedicated suction line
- Pressure-side: runs off a return line and may need a booster pump
- Robotic: self-contained, no pump connection
Suction-side cleaners: the pump does the pulling
A suction-side cleaner connects to the pool's suction path. The pump draws water through the skimmer or a dedicated suction line in the pool wall, and the cleaner is attached to that path with a hose. The pump pulls water through the cleaner body, and the debris travels with the water toward the pool's filter.
The ENERGY STAR pool pump page notes that filtration requires half the flow rate of running a pool cleaner. That stated comparison explains why a cleaner title and a pump title are read side by side: the pump must be able to deliver what the cleaner needs, and the maker's sizing page is the place to compare them.
The suction side of a pool includes the skimmer and other wall openings, and the U.S. Consumer Product Safety Commission's Pool Safely campaign is the national reference on suction safety.
A suction-side cleaner title often names the hose rather than the connection type. Words like "skimmer" and "hose" in a title are clues, and "fits" with a pool size or a pump figure is the seller's statement of the cleaner's intended system.
Pressure-side cleaners and booster pumps
A pressure-side cleaner connects to a return line. Water from the pump flows through a return fitting in the pool wall, and the cleaner rides that flow around the pool floor and walls. The cleaner trails a hose that attaches to the return fitting, and debris is pushed into a bag on the cleaner itself.
Some pressure-side cleaners are designed to run on the main pump's flow alone. Others are designed for a separate booster pump, a second pump on the pad that raises the water pressure sent to the cleaner. ENERGY STAR lists "pressure cleaner booster pumps" as a product category in its pool pump program, alongside inground and above ground pool pumps.
A listing that says "pressure-side" or names a booster pump as a companion part tells you the pad may need that second pump. A title that says "no booster pump required" is the seller's statement of the cleaner's design. Read the title for those words before buying. The inground pool pump guide and the above ground pool pump guide cover the pump side of the pad.
Robotic cleaners: no pump, no booster
A robotic cleaner is a self-contained unit with its own motor, intake, and filter. It does not use the pool pump or a booster pump. The ENERGY STAR pool pump page states that robotic cleaners are powered by low-voltage electricity rather than the pool pump or a booster pump, and that they collect dirt and debris in built-in filters.
Robotic cleaner titles use words like "cordless" and "corded" to describe power, and model lines such as Dreame or Aiper are often the only name in the title. "Wall climbing" appears in some titles as the seller's word for the robot's ability to drive up the walls. The wall climbing cleaner guide covers that feature.
Because a robotic cleaner does not connect to the pump, the pump and the cleaner are separate purchases. The only shared choice is the pool type: an inground robot is written for an inground pool, and an above ground robot for an above ground pool.
Hoses, fittings and what each title states
A suction-side or pressure-side cleaner listing often includes a hose length in the title, stated in feet. The hose connects the cleaner to the skimmer, the suction line, or the return fitting. A longer hose serves a larger pool, but the site does not match hose length to pool size; the maker's manual does that.
Fittings appear as listing words: quick connect, swivel, threaded adapter, or universal. These words describe how the hose joins the pool wall fitting or the cleaner body. They are stated details, and the part list is in the maker's manual.
A pump title and a cleaner title state different things. The pump title names speed type, horsepower, and voltage, as the pump horsepower article explains. The cleaner title names the connection type, the hose, and sometimes a booster requirement. The two are read as one system, and the suction versus pressure comparison explains the pump-side terms.
| Listing | What the title states |
|---|---|
| Pool pump title | Speed type, horsepower, voltage, pool type |
| Suction-side cleaner title | Connection type, hose length, skimmer or suction line |
| Pressure-side cleaner title | Connection type, return fitting, booster pump wording |
| Robotic cleaner title | Corded or cordless, wall climbing words, model line |
Questions to ask before buying
Before choosing a cleaner, read the listing's connection words and then the maker's manual. The manual states the cleaner's requirement: a skimmer connection, a dedicated suction line, a return fitting, or a booster pump.
Ask the pool builder which connection your pool has, and for a replacement cleaner, ask which type the previous cleaner used. The title of the previous cleaner is a good starting point.
Buying a pump and a cleaner together starts with the same reading: the pump title and the cleaner title are two parts of one system, and the maker's sizing page is the place to compare them. The variable speed pump guide covers pump shopping, and the Dreame cleaner guide covers a self-contained robotic option.

Questions
What is a suction-side pool cleaner?
A suction-side cleaner connects to the pool pump through the skimmer or a dedicated suction line. The pump pulls water through the cleaner, and debris travels toward the pool's filter. The listing states the connection with words like "suction-side" or names the hose and skimmer.
Do pressure-side pool cleaners need a booster pump?
Some do, some do not. A title that names a booster pump as a companion tells you the pad may need a second pump, while a title that says "no booster pump required" states the cleaner runs on the main pump's flow. ENERGY STAR lists "pressure cleaner booster pumps" as a product category in its pool pump program.
Do robotic pool cleaners connect to the pool pump?
No. A robotic cleaner is self-contained and is powered by low-voltage electricity rather than the pool pump or a booster pump, as the ENERGY STAR pool pump page states. It collects debris in its built-in filters.
What hoses and fittings does a pool cleaner need?
A suction-side or pressure-side cleaner title states a hose length in feet and may name fittings such as quick connect, swivel, or threaded adapter. The maker's manual shows the exact parts. Robotic cleaners do not use pad hoses.
Can an above ground pool use a cleaner that connects to the pump?
Yes, if the title states above ground compatibility. An above ground pool cleaner connects through the pool's skimmer or return fitting, and the pump title must also state above ground compatibility. Read both titles before buying.
