Robotic, Suction, or Pressure Cleaner: Which Type?
Short answer: Pool cleaner listings state the type in the title or first bullet. A robotic cleaner is a self-contained unit powered by low-voltage electricity with built-in filters; it does not run off the pool pump. A suction-side cleaner attaches to the skimmer or a dedicated line and uses the pool pump, sending debris into the pool filter. A pressure-side cleaner runs off the return water flow and often collects debris in its own bag. Read the type word first; it decides how the cleaner is powered and how it connects to the pool.
The three pool cleaner types
Pool cleaner listings state the type in the title or first bullet: robotic, suction-side or pressure-side. The type word tells you how the cleaner is powered and where the debris it collects goes. Identifying the type is the first step before you compare model names, cord length or wall climbing words.
This article reads those three words as listing terms and explains what each means for a pool owner choosing equipment. It compares stated details in listings; it has no data on how a cleaner performs in water.
Robotic cleaners: self-contained
A robotic cleaner is a self-contained unit with its own motor and built-in filter. The ENERGY STAR pool pump page describes robotic pool cleaners as powered by low-voltage electricity rather than the pool pump or a booster pump; the owner plugs the unit in and places it in the pool. The debris goes into the cleaner's own filter, not into the pool filter.
Because the robotic cleaner does not run off the pump, the listing does not ask you to match it to the pump's flow figure. The type word robotic is followed by other listing words: cordless or corded, wall climbing, and a stated pool type such as above ground or inground. Those words stay the seller's claims; this site compares how they read, not how they behave. See how a cleaner connects to the pump for the equipment pad angle.
Suction-side cleaners: run off the pool pump
A suction-side cleaner attaches to the pool's skimmer or a dedicated suction line and moves using the suction of the pool pump. Debris drawn in by the cleaner goes into the pool's own filter, so the pump, the filter and the cleaner work as one system.
The listing for a suction-side cleaner will say suction-side or describe the connection to the pump. Read whether it names the skimmer or a dedicated line, and whether the title states a pool type. The pump choice matters here because the cleaner depends on the pump to run; the suction-side cleaner matching page and the pump suction versus pressure page read those words in pump and cleaner titles.
Pressure-side cleaners: powered by return water
A pressure-side cleaner connects to the pool's return line and uses the pressure of water flowing back into the pool to move. Many pressure-side models collect debris in their own bag, so the dirt does not pass through the pool filter.
Some pressure-side listings name a booster pump. A booster pump is a separate pump that raises the water pressure for the cleaner. Whether your pool needs one is an installer's question; the listing only tells you that the cleaner expects one. The cleaner-to-pump connection page explains how each type is powered on the equipment pad.
Reading model names and maker lines
Maker model lines repeat the type word in their titles. Maytronics sells the Dolphin line of robotic cleaners and describes the units on its site; Aiper also sells robotic cleaners and titles many models with cordless and wall climbing words. Hayward lists pool cleaners as a product category next to pumps and filters.
When a title shows two type words or two figures, the type word is the shopping question. A title that says robotic tells you the unit is self-contained; a title that says suction-side tells you it uses the pump; a title that says pressure-side tells you it uses return flow. Compare model names only after the type word is clear, and read the Dreame cleaner guide or the wall climbing inground cleaner guide for model-level comparisons.
Above ground and inground in the title
Cleaner listings state a pool type with words such as above ground or inground. The type word decides which pool the seller lists the unit for; this site repeats the seller's pool type word rather than judging fit.
For a suction-side cleaner, the pool type also points to the pump. The sand filter pump guide reads the above ground pairing, and the inground pump guide reads the inground pairing. The above ground versus inground cleaner page covers the same words in both cleaner and pump titles.
What this site cannot say about cleaning
This site has no data on how a cleaner removes debris, how long it runs between charges, or how it behaves on a floor or wall. A listing's wall climbing word, run time figure or flow figure is the seller's statement, not a measured result. The site compares those stated details and leaves the rest to the maker's manual; the wall climbing capability page reads the wording only.
For questions about drains and suction outlets, this site points to the Pool Safely campaign; it does not cover drain or entrapment standards.
Checklist before you choose a type
Use this checklist to turn a title into a shopping decision. The type word comes first; the other words in the title are the seller's stated features, not promises of how the cleaner will work in the water.
- Read the type word first: robotic, suction-side or pressure-side.
- For a robotic cleaner, note whether the listing says cordless or corded, and which pool type it names.
- For a suction-side cleaner, note whether it connects to the skimmer or a dedicated line, and that it uses the pool pump.
- For a pressure-side cleaner, note whether the listing names a booster pump.
- Ask the maker for the product manual and any sizing page before purchase.
- Ask an installer about any new plumbing or pump connection the cleaner expects.

Questions
Does a robotic cleaner use the pool pump?
No. A robotic cleaner is powered by low-voltage electricity and collects debris in a built-in filter, so it runs independently of the pool pump, as the ENERGY STAR pool pump page explains.
What does suction-side mean in a listing?
It means the cleaner attaches to the pool's suction, either the skimmer or a dedicated line, and is driven by the pool pump. Debris it collects goes into the pool's own filter.
What does pressure-side mean in a listing?
It means the cleaner is driven by water pressure from the return line, and many models collect debris in their own bag. Some listings name a booster pump that provides that pressure.
Which type fits an above ground pool?
The listing states the pool type. Robotic and suction-side units are listed for both above ground and inground pools; read the pool type word in the title before buying.
What is a booster pump in a cleaner listing?
A separate pump that raises water pressure for a pressure-side cleaner. Whether your pool needs one is a question for an installer, not something to decide from the title alone.
Can a robotic cleaner climb walls?
Some robotic listings include the words wall climbing. That is the seller's stated capability; this site compares the wording and does not verify cleaning behavior.
