An automatic cleaner is the single best quality-of-life upgrade for a pool owner. But the three types work very differently, and the price gap is huge. Here's how to choose.
The three types, explained
Robotic cleaners ($500–$1,300)
Self-contained robots with their own motor, filter, and power supply. You drop one in, plug it into an outlet, and it drives itself around the pool — scrubbing floors, climbing walls, and cleaning the waterline. It doesn't touch your pump or filter system at all.
Suction-side cleaners ($200–$500)
These plug into your skimmer or a dedicated suction line and let your pump's suction drag them around in a random pattern. Cheap and simple, but they clean mostly floors, put extra load on your pump, and can't climb walls well.
Pressure-side cleaners ($400–$800)
These connect to a return line (often needing a separate booster pump) and use water pressure to move, collecting debris in an attached bag. Better than suction-side at walls, but the booster pump adds energy cost and complexity.
Head-to-head comparison
| Factor | Robotic | Suction-side | Pressure-side |
|---|---|---|---|
| Cleans floors | Excellent | Good | Good |
| Cleans walls | Excellent | Poor | Fair |
| Waterline scrubbing | Yes (most models) | No | No |
| Energy use | Very low (~180W) | High (runs your pump) | High (+ booster pump) |
| Filter load | None (own filter) | Loads your filter | Bag (less load) |
| Typical price | $500–$1,300 | $200–$500 | $400–$800 |
What to look for in a robotic cleaner
- Wall climbing + waterline cleaning — the waterline is where grime builds up; budget robots skip it
- Filter type — fine filter baskets or cartridges catch more than basic mesh bags
- Cycle options — floor-only quick cycles save time on light debris days
- Cord vs cordless — corded robots run longer; cordless (battery) models are newer and more convenient but need recharging
- Warranty — 2+ years is the mark of a manufacturer that stands behind the product
Our take: for most residential pools, a mid-range robotic cleaner ($600–$800 on sale) is the best value in pool equipment. It cleans better than the alternatives, slashes energy use, and extends the life of your pump by reducing its workload.

Frequently asked questions
Are robotic pool cleaners worth the money?
For most pool owners, yes. Robotic cleaners scrub floors, walls, and the waterline independently of your pump, use very little electricity, and reduce pump run time. A mid-range robot ($600–$800 on sale) typically pays for itself in energy savings and avoided pump wear within a few seasons.
What is the difference between robotic, suction, and pressure-side cleaners?
Robotic cleaners are self-powered and plug into an outlet — they clean floors, walls, and waterline with their own motor and filter. Suction-side cleaners attach to your skimmer and use pump suction, cleaning mostly floors in a random pattern. Pressure-side cleaners use return-line water pressure (often with a booster pump) and collect debris in a bag.
How long do robotic pool cleaners last?
A quality robotic cleaner lasts 5–8 years with normal use. The most common failure points are the power supply and drive tracks. Rinsing the unit after use and storing it out of the sun extends its life significantly.
Do robotic cleaners climb walls?
Most mid-range and premium robotic cleaners climb walls and scrub the waterline. Budget robots may only clean floors. Check the specs for "wall climbing" and "waterline cleaning" if that matters for your pool.
Can a robotic cleaner replace my pool pump's cleaning cycle?
Largely, yes. Because robots filter independently, many owners cut daily pump run times significantly, which is where the energy savings come from. You still need the pump for circulation, heating, and chemical distribution.
