Quick Answer: The Pentair Prowler 920 is a corded, low-voltage robotic pool cleaner rated for inground pools up to about 50 ft, with dual interchangeable fine/coarse filter cartridges and a 1-year warranty. Pentair has discontinued the model at the manufacturer level, but US retailers are still selling remaining stock for $1,097.99-$1,299 — well above the roughly $799 figure sometimes quoted for it, and well above the sale price several third-party blogs describe. It’s also frequently mislabeled online as a cordless, battery-powered robot with a 2-hour runtime; Pentair’s own spec sheet and an independent CHOICE test both confirm it’s actually corded.
The Prowler 920 has been listed in our best Pentair pool cleaner guide as the pick for smaller and above-ground setups, but it never had its own dedicated review — and digging into current availability and specs turned up a more complicated (and more expensive) picture than the marketing copy suggests.

By the numbers
- Price reality check: Discount Pool Supply lists the Prowler 920 at $1,299 (13% off $1,499.99) and PoolZoom lists it at $1,097.99 (22% off $1,399, currently temporarily out of stock) — both well above the roughly $799 figure some guides (including an earlier version of ours) have quoted.
- Discontinued status: Pentair’s own product page for SKU 360322 marks the Prowler 920 as discontinued, confirming the retailer listings above are sell-through of remaining inventory rather than an active product line.
- Cleaning range: Pentair rates the Prowler 920 for a maximum cleaning length of about 15.3 m (50 ft), per CHOICE’s independent Australian test — the same coverage Pentair quotes for the flagship Prowler 930, not a scaled-down above-ground-only range.
- Warranty: Just 1 year, confirmed by both CHOICE’s test and Discount Pool Supply’s listing — shorter than the 2-3 year warranties typical of Dolphin and Beatbot robots covered elsewhere on this site.
What it does well
Dual-cartridge filtration adapts to debris type. Swap in the fine cartridge for pollen and dust, or the coarse cartridge for leaves and twigs — a simple, no-tools way to match filtration to what’s actually in your pool that season.
Wall-to-floor scrubbing with a dedicated high-speed brush. Pentair’s spec sheet lists a scrubbing brush that spins at twice the speed of the drive tracks, aimed specifically at breaking up stuck-on algae and scum rather than just vacuuming loose debris.
Self-contained and low-voltage, like the rest of the Prowler line. No hoses, no booster pump, and no added load on your pool’s main pump or filter — the same independent-operation advantage as Pentair’s Prowler 930 and the robotic cleaners from Dolphin, Beatbot, and WYBOT covered in our best robotic pool cleaner guide.
Built-in scheduling. The weekly timer lets you set daily cleaning cycles without needing an app, useful if you’d rather not manage a Wi-Fi connection for a pool robot.
Where it falls short
- Discontinued, with no manufacturer replacement announced. Pentair has pulled the Prowler 920 from its current lineup, which means no more new units, and long-term parts and warranty support will likely get harder to find as retailer stock sells through.
- Real prices run well above older $799 estimates. At $1,097.99-$1,299 for remaining stock, the Prowler 920 now competes directly with premium robots like the Dolphin Nautilus CC Plus (
$799) and even edges toward Dolphin Sigma territory ($1,499) — a much tougher value case than the price this model is often quoted at. - Short 1-year warranty. Competing robots on this site, including several Dolphin and Beatbot models, typically carry 2-3 year warranties — a meaningful gap on a $1,000+ purchase, especially one the manufacturer has already discontinued.
- Widespread misinformation online. Several third-party review sites describe the Prowler 920 as a cordless, ~2-hour-battery robot, which contradicts Pentair’s own spec sheet and CHOICE’s independent test. Buyers relying on those descriptions may be surprised to find an 18.3 m power cable in the box instead of a charging dock.
- No Wi-Fi/app control. Unlike the 930 W variant in Pentair’s own lineup, the 920 relies on its built-in timer only — no remote spot-cleaning or smartphone scheduling.
Pentair Prowler 920 vs Prowler 930
| Spec | Prowler 920 | Prowler 930 |
|---|---|---|
| Pool type | Inground, up to ~50 ft | Inground, up to ~50 ft |
| Power | Corded, low-voltage | Corded, low-voltage |
| App/Wi-Fi | No (timer only) | Yes, on the 930 W variant |
| Filtration | Interchangeable fine/coarse cartridges | Top-load cartridge |
| Warranty | 1 year | Longer, varies by retailer |
| Availability | Discontinued; sell-through only | Current flagship, per our guide |
Both share the same corded, self-contained design and roughly 50-ft coverage — the 920 was never the above-ground-specific model it’s sometimes described as. With Pentair’s whole Prowler line now winding down, the practical question isn’t 920 vs. 930 on paper; it’s whichever one a retailer still has in stock at a real discount.

Who should buy the Pentair Prowler 920
Buy it if you’re already invested in the Pentair ecosystem, find one in stock at a genuine discount, and want a straightforward corded robot with swappable fine/coarse filtration and no Wi-Fi dependency.
Skip it if you’re comparison-shopping from scratch — at $1,097.99-$1,299 for a discontinued, 1-year-warranty model, a currently-supported robot like the Dolphin Nautilus CC Plus offers a longer warranty and active manufacturer support for similar or less money. See our best inground pool cleaner guide for the current field.
The bottom line
The Pentair Prowler 920 is a competent corded robot — dual-speed scrubbing, adaptable filtration, and Pentair’s low-voltage self-contained design — but the model Pentair has already discontinued now costs considerably more on the sell-through market than older estimates suggest, carries just a 1-year warranty, and is commonly misdescribed online as a cordless battery robot it never was. If you can find genuine remaining stock at a strong discount and want to stay inside the Pentair ecosystem, it still cleans well. Most other buyers are better served by an actively-supported robot with a longer warranty — see our best robotic pool cleaner guide for the current field.
