Quick Answer: As of September 2026, four robotic pool cleaners tracked on this site are officially discontinued but still findable as retailer “clearance” or sell-through stock: the Pentair Prowler 930 W ($1,699.00), Beatbot AquaSense Pro / AquaSense 2 Pro (remaining Amazon/retailer listings), Hayward AquaVac 650 ($1,467.99, Walmart), and WYBOT Osprey 200 (under $150). None of them currently beat their best actively-manufactured equivalent on price plus warranty — the Prowler 930 W, in particular, now costs more than the currently-sold Dolphin Sigma despite losing all manufacturer support. Clearance pricing on a discontinued robot isn’t automatically a bargain; it’s sell-through inventory priced however the last seller wants.
“Clearance” implies a discount deep enough to offset what you’re giving up, but robotic pool cleaners don’t work like clearance racks at a department store. Once a manufacturer discontinues a model, remaining units become sell-through inventory — priced by whichever retailer still has stock, not marked down on any predictable schedule. That means a “clearance” robotic pool cleaner can just as easily be priced at or above its original list, with none of the manufacturer support that justified the price when it was current. Below is exactly where that math works, and where it doesn’t, across every discontinued model this site has reviewed.
Discontinued models still on shelves, at a glance
| Model | Status | Clearance / sell-through price | Currently-sold alternative | Real verdict |
|---|---|---|---|---|
| Pentair Prowler 930 W | Fully discontinued, no successor named | $1,699.00 (down from $1,759.99 list) | Dolphin Sigma, ~$1,499, 3-yr warranty | Avoid — costs more than the current alternative |
| Beatbot AquaSense Pro / 2 Pro | Both generations discontinued in a row | Varies — remaining Amazon/retailer stock only | Beatbot AquaSense 2 Ultra, ~$2,649-$3,150 | Only at a steep, verified discount — no Beatbot warranty backing |
| Hayward AquaVac 650 | Discontinuation signals; sell-through only | $1,467.99 (Walmart, 19% off $1,812.50 list) | Hayward TigerShark QC, $1,199-$1,202 | Skip — pricier than Hayward's own steered replacement |
| WYBOT Osprey 200 | No longer listed on WYBOT's own site | Under $150 street price | WYBOT A1, ~$299 | Only if budget is the sole priority — independent testing found it underpowered even new |
Pentair Prowler 930 W: the clearest clearance trap
Pentair’s entire robotic Prowler lineup — the above-ground 910, the 920, the 930, and the Wi-Fi 930 W — is discontinued at the manufacturer level, per Pentair’s own product pages, with no replacement robotic model named. That should mean deep discounts on remaining stock. Instead, per our full Prowler 930 review, EZ Test Pools currently lists the last available 930 W stock at $1,699.00, down only slightly from a $1,759.99 list price — and frequently out of stock entirely. That’s more than the actively-manufactured Dolphin Sigma, which typically runs around $1,499 with three commercial-grade motors, gyroscope navigation, and a full 3-year warranty from Maytronics. A discontinued robot with no manufacturer support shouldn’t cost more than a supported one doing the same job — this is the single clearest example of “clearance” pricing failing to reflect what you’re actually giving up.
Beatbot AquaSense Pro and AquaSense 2 Pro: two discontinued generations in a row
Beatbot’s mid-flagship cordless line has an unusual history: the original AquaSense Pro (A100PRO) was discontinued and replaced by the AquaSense 2 Pro — which Beatbot’s own product page has since also marked “no longer available,” per our AquaSense Pro review. Any remaining stock of either model now comes from Amazon or third-party retailers rather than Beatbot directly, meaning Beatbot’s standard warranty coverage doesn’t reliably apply. Beatbot’s actively-sold flagship today is the AquaSense 2 Ultra (~$2,649 sale/$3,150 list) — so a clearance AquaSense Pro or 2 Pro listing is only worth considering if it’s priced dramatically below that, with the buyer accepting that Beatbot itself no longer backs the unit.
Hayward AquaVac 650: priced above Hayward’s own recommended replacement

Hayward’s own support documentation for the sibling AquaVac 600 states that model “has been discontinued” and directs buyers to the TigerShark QC instead — a strong signal the whole 6 Series, including the AquaVac 650, is winding down in the US even though Walmart still lists it new at $1,467.99 (19% off a $1,812.50 list), per our full AquaVac 650 review. The catch: Hayward’s own currently-supported TigerShark QC sells for $1,199-$1,202 — hundreds less than the “discounted” discontinued model it replaces, with a full 3-year parts-and-labor warranty through authorized dealers. Buying the AquaVac 650 on clearance means paying more for less support than Hayward’s own recommended current pick.
WYBOT Osprey 200: the one case where clearance pricing is at least honest
The WYBOT Osprey 200 is the exception that proves the rule: it’s no longer listed on WYBOT’s own current product pages, but remaining street stock sells for under $150 — genuinely the cheapest robotic pool cleaner this site tracks, discontinued or not. The trade-off is real, though: independent testing found it underpowered even when it was current, and WYBOT’s own above-ground successor, the WYBOT A1 (~$299), is the brand’s actively-supported pick for the same job. The Osprey 200 is worth considering only if price is the single deciding factor and you’re comfortable with weaker cleaning performance and zero ongoing manufacturer support.
By the numbers
- $1,699.00 vs. ~$1,499: the discontinued Pentair Prowler 930 W’s sell-through price versus the actively-manufactured Dolphin Sigma’s typical street price — a discontinued, unsupported robot costing more than a supported one, per EZ Test Pools and Maytronics’ own pricing.
- 19% off, but still pricier than the replacement: the Hayward AquaVac 650’s $1,467.99 Walmart price is a genuine 19% cut from its $1,812.50 list — yet it’s still $265-$269 more than the TigerShark QC that Hayward’s own support team steers buyers toward instead.
- Two generations, one discontinuation pattern: Beatbot has discontinued both the original AquaSense Pro and its direct successor, the AquaSense 2 Pro, in back-to-back product cycles — a rare case of a flagship’s replacement getting pulled from sale within the same era, per Beatbot’s own product pages.
Dolphin Nautilus CC Plus
- Currently sold new by Maytronics with full manufacturer parts and warranty support — no discontinuation risk.
- The safer default when a discontinued "clearance" listing doesn't clear the bar on this page.
The bottom line
“Clearance” on a discontinued robotic pool cleaner doesn’t carry the same guarantee it does in other categories — there’s no manufacturer marking these down to move volume, just whatever price the last retailer with stock decides to charge. Of the four discontinued models tracked on this site, the Pentair Prowler 930 W and Hayward AquaVac 650 both currently cost more than the actively-manufactured, fully-warrantied model each brand steers buyers toward instead, making them the clearest traps. The Beatbot AquaSense Pro/2 Pro and WYBOT Osprey 200 are only worth it at a genuinely steep discount, with the buyer knowingly accepting reduced or nonexistent manufacturer support. Before buying anything advertised as “clearance” in this category, check what the same brand’s current-generation model actually costs — see our best robotic pool cleaner guide for the full current field, or our robotic pool cleaner deals guide for verified sale prices on models still in production.
