Description
Spend more time swimming and less time vacuuming with the Pentair Prowler 360321. It is designed for above-ground pools with a 40 ft hose.
Prowler 910 is a Pentair robotic cleaner for above-ground pools (powered by Dolphin) that runs independently of the pool pump with a scrubbing brush and top-access filter basket. Below we explain how robotic cleaners work, how to choose one for your pool and how to keep it running well.
Quick Answer: What Is the Pentair Prowler 360321?
The Pentair Prowler 360321 is a robotic automatic pool cleaner for above-ground pools. It moves around the pool on its own, collecting dirt and debris so you do not have to vacuum by hand.

How Automatic Pool Cleaners Work
- Suction cleaners connect to the skimmer or a dedicated suction line and use the pump's suction to move and vacuum. Debris goes to the pump basket or an inline leaf canister.
- Pressure cleaners connect to a return line, often with a booster pump, and collect debris in an onboard bag.
- Robotic cleaners are self-contained, with their own motors, filters and a low-voltage power supply. They do not rely on the pool pump and are the most energy-efficient option.
This model is a robotic cleaner.
How to Choose a Pool Cleaner
Match the cleaner to your pool type (in-ground or above-ground), surface (plaster, pebble, vinyl or fiberglass), size and shape, and the kind of debris you get. Fine dust and sand favor robotic cleaners with fine filters; heavy leaves favor cleaners with large debris capacity or an inline leaf canister. Make sure the hose or cord reaches the farthest point of the pool.
Good, Better, Best: Where the Pentair Prowler 360321 Fits
At HVAC365 we organize every category into a simple Good, Better, Best framework so you can compare options without wading through jargon. Within our pool cleaner lineup, this model sits in the Better tier: Enhanced comfort and smarter control.
The Better tier steps up efficiency and adds smarter control. It balances up-front cost with lower operating cost and more convenience, which is why property managers and owners who plan to keep their equipment for years often land here.
Not sure the Better tier is right for you? Compare it with the Good and Best options in the same category. Whatever tier you choose, the equipment is brand new and covered by the full manufacturer warranty, and our team is here to help you weigh features against budget.
Setup Tips
Suction cleaners need a properly adjusted suction port and a clean pump basket. Pressure cleaners need the right return-line pressure, often from a dedicated booster pump. Robotic cleaners plug into a GFCI-protected outlet, with the power supply kept at a safe distance from the water as described in the manual. Our team can help you set up the right connection for your system.
Maintenance
- Empty the debris bag, canister or filter after each use or as needed.
- Inspect hoses, tires, tracks, brushes and wear parts, and replace them when worn.
- Store robotic cleaners out of direct sun when not in use.
- Keep the pump and filter clean so suction and pressure cleaners perform their best.
Cleaners by Region
Pools in the South and Southwest face year-round dust, pollen and leaves, so a cleaner that runs often pays for itself in time saved. In northern areas, a cleaner makes spring opening and leaf season far easier.

Suction vs Pressure vs Robotic: Side-by-Side
| Factor | Suction | Pressure | Robotic |
|---|---|---|---|
| Power source | Pool pump suction | Return line, often a booster pump | Own low-voltage motor |
| Where debris goes | Pump basket or leaf canister | Onboard debris bag | Onboard filter |
| Up-front cost | Lowest | Moderate | Highest |
| Operating cost | Requires pump run time | Booster pump adds energy | Lowest energy use |
| Best for | Budget, small debris | Leaves and larger debris | Fine dirt, walls and waterline |
Each type keeps a pool clean when it is matched to the pool and set up correctly. Suction cleaners are the simplest and most affordable way to automate cleaning, especially for above-ground pools and pools with light debris. Pressure cleaners handle heavier leaf loads without clogging the pump basket. Robotic cleaners cost more up front but clean the most thoroughly, scrub walls and waterlines, and use the least energy because they run independently of the main pump. A cleaner also helps your filtration system by picking up debris before it breaks down, which can reduce chlorine demand and keep the filter cleaner for longer.
Getting the Best Results
Run the cleaner after storms, heavy use and leaf drop, and brush steps, corners and other areas cleaners cannot reach. Keep water balanced so surfaces stay smooth and debris releases easily. Check that the skimmer weir and valves are set correctly for suction cleaners, and that the cleaner is not getting stuck on drains, steps or lights; most manufacturers offer adjustment parts and accessories for tricky pools.
Above-ground pools have their own needs. Their walls and floors are usually vinyl liners, so cleaners designed for above-ground pools use gentle brushes and tracks that will not damage the liner, and they are sized for smaller, simpler floor plans. In-ground pools with steep slopes, deep ends or textured finishes need cleaners with stronger climbing and traction.
