Pentair Prowler 920 Robotic Pool Cleaner Review - Worth It?

The Pentair Prowler 920 is a mid-price robotic pool cleaner that is somewhat less well-known than other brands. This machine carries a slightly higher price point than some machines available on the market, but how well does it clean?

In this Pentair Prowler 920 review, we’ll cover the pros and cons of this machine, compare it to other similar products on some main features, and answer frequently asked questions about this model to help you decide if this model of pool cleaner would be right for your pool.

Pros & Cons


  • Easy to use and clean
  • Works well on walls and waterline
  • Caddy for easy transport and storage
  • Great with small or large debris
  • Fairly lightweight (7.5kg)


  • Can get stuck temporarily on drains, steps, ledges
  • Cord prone to tangling and breaking down
  • Some issues covering entire pool
  • Heavy water output that disturbs nearby debris


The Pentair Prowler 920 is a mid-size, fairly lightweight pool cleaner for pools that are no more than 12 metres in length. This cleaner is not one of the lightest models available, but is not particularly heavy either at 7.5kg. Most consumers who have owned this cleaner suggest that it is relatively easy to lift and transport.

This robotic pool cleaner is capable of climbing walls and cleaning the waterline of your pool. It is supposed to clean steps and ledges, but there are mixed reviews about how well it cleans these types of areas. The Pentair Prowler 920 comes with a caddy included.

This cleaner has a sleek design that is primarily grey with blue elements such as the top handle. This colour scheme makes the cleaner blend into your pool’s environment somewhat, making it less of an eyesore than bright or bold colored cleaners.

Cleaning Performance

The Pentair Prowler 920 is great at cleaning the floors, walls, and waterline of your pool. Compared to other robotic pool cleaners on the market, this machine has much more favourable reviews regarding the climbing and waterline cleaning ability.

The Prowler 920 is specifically designed for in-ground pools. Of these, it is compatible with almost all pool liners. This cleaner is equipped with a top-loading filter basket cartridge that works well on both small and large debris.

Many consumer reviews of this product discuss how satisfied owners are with the machine’s ability to pick up large tree-borne debris, such as leaves, twigs, and pine needles.

This machine, like other pool cleaners, can occasionally struggle with debris that is found on corners, steps, or ledges, but overall receives positive reviews in these areas as well.

The Pentair Prowler 920 can be set up on a cleaning schedule during which it will automatically activate. This machine will climb the walls during each cleaning cycle; there is no setting for this cleaner that will allow it to focus on the floors of the pool exclusively.

The 920 model of the Pentair Prowler is not bluetooth compatible and does not have remote control capabilities.

Build Quality & Warranty

Pentair Prowler 920 Problems

The Pentair Prowler 920 is not known to have any major problems with the build quality or structural integrity of the machine. A couple of reviews about this cleaner have noted that they are dissatisfied with the quality of the power cord, stating that it becomes tangled more easily than cleaners by other brands.

Additionally, the power supply unit is not thoroughly waterproofed. Although this unit is not meant to come near your pool’s water (as is outlined in the operating manual), if it were to fall into the water accidentally, it would likely sustain severe damage.

Another very minor problem of the Pentair Prowler 920 is that it has a strong outflow point where cleaned water re-enters your pool. Although this signifies a high-quality motor, the strong jets of water that it gives off may disturb nearby debris, making it harder for the cleaner to pick this up later.

Pentair Prowler 920 Warranty

The Pentair Prowler 920 has a two-year warranty, which is fairly standard among robotic pool cleaners. Compared with machines by other brands (such as the Zodiac CX20), this model has much fewer customer reviews about breakage occurring, either during or after the warranty has expired, suggesting that it is designed with longevity in mind.

Pentair Prowler 920 Price

The Pentair Prowler 920 is somewhat more expensive than other cleaners, costing about $1,700. Although this is a premium price point for a cleaner of this size, we find that the quality of this product makes it a worthy investment.

Pentair Prowler 920 - FAQ

Can I Leave The Pentair Prowler In The Pool?

The Pentair Prowler 920 can be set up on a cleaning schedule, suggesting that it is fine to keep this robotic pool cleaner in your pool when it is not in use.

However, like all robotic pool cleaners, certain elements of the construction of the machine may wear out faster if they are exposed consistently to pool water. This is usually the result of UV degradation.

To reduce wear on your machine, remove it from the water when it is not being used.

If you opt to leave the machine in the pool so it can come on daily for its scheduled cycle, you should ensure that your pool’s chemistry is well-balanced in order to decrease the likelihood of chemical-related deterioration.

How Do I Reset My Pentair Prowler 920?

To reset your Pentair Prowler 920, press the ‘weekly timer’ button four times in a row. You should then immediately select your ideal scheduling setting, or else the cleaner will default to running one single cycle without syncing up to a schedule.

How Long Is The Prowler 920 Cleaning Cycle?

The Pentair Prowler 920 has a cleaning cycle of two and a half hours. If you are using a pool that is larger than this cleaner is intended for, you may need to run two cleaning cycles to achieve best results.

Final Thoughts - Pentair Prowler 920 Review

The Pentair Prowler 920 makes a great choice if you are willing to invest in a higher-quality pool cleaner. Although cheaper options are definitely available, comparable products tend to lack the consistently positive customer reviews that can be found for this model of machine.
