Dolphin Triton PS Review (2026): Discontinued Since 2023 — Still Worth Buying?

Quick Answer: The Dolphin Triton PS is a Maytronics robotic pool cleaner that cleans floor, walls, and waterline on inground pools up to 50 ft, with a 2-hour cycle and a programmable weekly timer — but per Poolbots’ own tracking, it has been discontinued since 2023. Maytronics’ current US store no longer lists it at all, yet retailers like Sunplay, Wellbots, and Pool360 still sell remaining stock, which is why “dolphin triton ps” still pulls real search volume years after the model left production. Poolbots’ verdict is blunt: skip it, since sellers often charge up to a 20% restocking fee and the currently-manufactured Dolphin Sigma or Dolphin Premier both out-clean it with active manufacturer support.

Every other Dolphin family covered on this site — Nautilus CC, Explorer, Advantage, Proteus — is a currently-sold lineup. The Triton is different: it’s a product people are still actively searching for and buying from leftover retailer stock, without realizing Maytronics itself walked away from it years ago.

By the numbers

• Discontinued since 2023, confirmed directly: Maytronics’ own current US store no longer lists the Triton PS or Triton PS Plus at all — the lineup it now shows under “best-seller cleaners” is the Nautilus Titan, Explorer E50, EON 100, and Liberty series. Poolbots independently confirms the discontinuation date as 2023.
• Restocking fees eat into any “deal”: Poolbots flags that sellers of remaining Triton PS stock “charge up to a 20% restocking fee” if a buyer wants to return it — a real cost that doesn’t show up in the sticker price, and one that doesn’t apply to a currently-sold robot bought through a standard 30-day retailer trial.
• Price spread reflects the sell-through chaos: Maytronics’ pricing history put the Triton PS around $899-$999, while Poolbots documents $1,049 — a wider spread than this site typically sees on actively-manufactured models, where retailers usually track within $50 of each other.

Where it falls short

• No manufacturer support, full stop. Unlike the handoff this site documented between Hayward’s discontinued AquaVac 650 and its supported TigerShark QC replacement, Maytronics hasn’t named a direct Triton successor — buyers are left comparing it against whatever’s currently in Maytronics’ lineup rather than a clear 1-to-1 upgrade path.
• No NanoFilters. Per Poolbots, the Triton PS “lacks NanoFilters™ and cannot clean smaller debris and algae” as effectively as current Dolphin models that include them, a real cleaning-performance gap, not just a missing convenience feature.
• Lower suction than current models. Poolbots’ review also notes “lower suction power compared to current models” — consistent with the Triton PS predating the motor platforms used in the Sigma and Premier.
• Base PS has no app at all. Even the Plus variant’s Wi-Fi control is basic smartphone remote access, not the scheduling and spot-clean modes current Dolphin app-connected robots offer through MyDolphin Plus.

What it still gets right

Full floor-walls-waterline coverage for a 50 ft pool. Whatever its age, the Triton PS’s core coverage claim matches what Maytronics’ current mid-tier robots still promise — it just does it with older hardware.

A genuine weekly timer on both variants, including the base PS without Wi-Fi — something several of Maytronics’ current entry-tier Explorer and Liberty models still don’t include at their lowest price points.

PowerStream Technology for turning and climbing. Per Maytronics’ own marketing copy for the model, the Triton PS used active-brush scrubbing at twice the robot’s driving speed for wall traction — a real engineering feature, not just a cycle-time number.

Dolphin Triton PS vs. Dolphin Sigma

The price gap is smaller than it looks once the Triton’s restocking-fee risk and lost manufacturer support are priced in. For roughly $450-$600 more, the Dolphin Sigma adds a second and third motor, gyroscope-guided navigation, and an active 3-year warranty — the exact upgrade path Poolbots points buyers toward instead of the Triton. Buyers who specifically want to stay closer to the Triton’s original price point should look at the Dolphin Nautilus CC Plus (~$749, also floor-walls-waterline, also currently manufactured) before considering discontinued sell-through stock.

Who should buy the Dolphin Triton PS

Buy it only if you find genuinely cheap sell-through stock (well under $899) and fully accept zero ongoing manufacturer support, no NanoFilter upgrade path, and a possible restocking fee if it doesn’t work out.

Skip it if you’re comparison-shopping from scratch. A currently-manufactured robot like the Dolphin Sigma or Dolphin Premier covers the same floor-walls-waterline job with active Maytronics support, better filtration, and a longer warranty — see our best Dolphin pool cleaner guide for the current lineup.

The bottom line

The Dolphin Triton PS cleaned floor, walls, and waterline on a 50-ft pool with a genuine weekly timer and active-brush scrubbing — solid hardware for its era. But Maytronics discontinued it in 2023, and the retailers still listing it as “available” are selling down leftover stock with no NanoFilters, no manufacturer warranty backing, and sometimes a 20% restocking fee if it goes wrong. If you’re searching for it because it showed up in a retailer listing, treat that as a yellow flag rather than a deal — see our Dolphin Sigma review or our pool cleaner clearance guide for how this kind of sell-through pricing compares to every other discontinued model this site tracks.
