Maytronics Dolphin Triton PS

Name: Maytronics Dolphin Triton PS
Brand: Maytronics

PowerStream steering jets hold the unit against the surface, which keeps the brush in contact on floors and walls and in moving water. Deployment is manual and there is no app: cycle selection and the weekly timer sit on the poolside power supply unit. Trade-off: the model is discontinued, with Maytronics moving the segment to the Dolphin ACTIVE line, so a new unit is no longer ordered from the manufacturer.

Autonomy Ladder

Why Level III.

One five-rung scale, every category, from acting only on command to working unsupervised anywhere.

VGeneralized AutonomyAny task, any setting. No consumer robot has reached it.
IVEnvironmental AutonomyCopes with everyday clutter and frees itself, shown by independent testing.
To reach Level IVIndependent testing shows it avoids ordinary obstacles before contact, copes without the space being cleared, and frees itself when stuck.
IIIConditional AutonomyThis robot

Maytronics Dolphin Triton PS finishes whole jobs in a space it already knows, and still needs a person at the edges.

Navigation and control

Two independent motors: floor and wall via PowerStream jet pressure
Why this level
- Two motors drive the brush and the drive system on deterministic cycles, with PowerStream jets holding the unit to the surface rather than adapting the route.
- The operator selects the cycle and sets the weekly timer.
- Navigation does not respond to pool layout or debris concentration, but coverage of the defined surfaces completes without intervention once a cycle is running.

Our assessment did not establish an independent source for coverage and navigation, operating envelope on this machine, so those inputs are left out of the score rather than guessed at, and the rest re-weighted to fill the space. A gap in what we have been able to verify is not evidence against the robot. Where a whole pillar has nothing measured, we publish no number at all.

Capability40% of the score45What it does without you.

Task completion16% of the score55

Evidence

Two separate JustAnswer owner threads on the Triton PS report it flipping over and not coming out, and stopping mid-cycle often. No retrieved independent source documents a completed full-pool cycle; the wellbots, poolzoom, poolsupplyunlimited and marinapoolspaandpatio pages all carry the same Maytronics marketing paragraph and are vendor copy on dealer servers.

Coverage and navigationnot countedno source verified46

Evidence

Deterministic cycles, and the record is explicit that navigation does not respond to pool layout or debris concentration and that PowerStream holds the unit to the surface rather than adapting the route. Below the re-established-every-run anchor because there is no scan and no survey either: the pattern is fixed and the same pattern runs in every pool, so a missed area is missed the same way each time.

Edge-case recovery10% of the score30

Evidence

The JustAnswer thread on the Triton PS stopping mid-cycle reports it halting without displaying any error at all, and a second thread reports it powered but immobile until the owner cleared debris from the drive wheels. That is the found-stalled and unreported pattern, not self-recovery, and no source shows it freeing itself.

Operating envelopenot countedno source verified56

Evidence

In-ground only to 50 ft, with above-ground and shallow installations excluded outright because the two-motor pressure design is engineered for in-ground depth and wall angle and would run into pressure imbalance elsewhere. Significant floor debris or algae buildup produces incomplete pickup. The genuine credit is narrow but real: it holds wall contact in moving water, which is the condition that defeats lighter cleaners.

Dependability40% of the score61Whether it keeps doing it.

Field failure rate16% of the score81

Evidence

Eight years since May 2018 with no major recall documented and owner reports describing consistent multi-season operation. Cut by one documented job-stopping mode with a hard price attached: PowerStream pump seal leakage, inspected on a 2 to 3 year cadence and remedied at roughly $400 of professional service, which against a $1,049 machine sits at the edge of proportionate. Manufacturer documentation is pending and the owner and service-professional evidence is unlinked, so the forum and retail cap applies.

Software stability14% of the score33

Evidence

The no-update-channel anchor. Connectivity is empty and the record is emphatic: no account creation, no app pairing, no network step, with everything set on the poolside power supply. There is no owner-facing update path, so under rule 1 this earns nothing rather than credit for simplicity.

Support longevity10% of the score67

Evidence

Discontinued, which this input weighs directly: Maytronics has moved the segment to the Dolphin ACTIVE line and retailers list this one sold out or refurbished only. What keeps it well above an orphan is that the record is specific about the channel surviving the model: replacement parts and filter cartridges are still stocked by pool parts retailers at $40 to $60 a cartridge, and pump seal replacement remains an available professional service, so an owned unit stays serviceable. No warranty term or support window appears.

Ownership burden20% of the score53What it asks of you.

Routine maintenance12% of the score53

Evidence

Heavier than its Dolphin siblings on items none of them carry: a monthly inspection of the PowerStream pump housing for drips or pressure leaks, a monthly silicone lubrication of the cable swivel joint, an annual pump seal inspection for degradation or mineral accumulation, and a winterization that drains the pump lines as well as the cable. On top of the usual cable and swivel check after every use and a filter rinse weekly in debris season, on an 18.7 lb machine. The power supply's weekly timer is the offsetting credit.

Consumables8% of the score54

Evidence

The worst consumables position of any corded Dolphin here and the only one with a genuine calendar. The filter cartridge is replaced annually at $40 to $60 rather than washed and refitted like the two-kit models, and behind it sits a pump seal at roughly $400 every 2 to 3 years where leakage is observed. That is conditional rather than scheduled, which is why this is not lower, but on a machine that listed at $1,049 a single seal service is nearly 40 percent of the purchase price.

OWNERSHIP

Living with it.

Eight years in market with stable two-motor operation. PowerStream pump and independent floor motor create dual failure vectors, but documented field performance shows rare pump seal failures.

Owner reports from eight-year user base document consistent performance with minimal unplanned service calls. PowerStream pump replacement (rare, ~$400 if needed) is the most common service intervention. No documented motor failures in field data. Filter cartridge is annual consumable.

Common questions

What people actually ask.

6 answered

OperationWhat is PowerStream, and does it damage plaster or tile?

PowerStream is Maytronics’ mobility system, not a cleaning jet. Directional water jets hold the unit against the surface and steer it, which keeps the brush in contact on floors and walls and holds a line when pool return flow or wind would push a lighter cleaner off course. Scrubbing is done by the brush and the suction intake. Nothing is aimed at the wall as a pressure wash, and there is no intensity setting to adjust for surface type.

OperationDoes the Triton PS require a separate dock motor or power supply compared to the E10?

It runs from a poolside power supply unit, a low-voltage transformer carrying on/off, cycle selection and a weekly timer. There is no dock, no external pump and no installation wiring: the power supply plugs into a standard GFCI outlet, and the pump driving suction and the PowerStream jets sits inside the robot.

OperationCan I use a 40-foot cable on the Triton PS, or does it require the full 60 feet?

The Triton PS ships with a 60-foot floating cable, rated for pools up to 50 feet. Cable length has no bearing on jet performance: the jets are fed by the robot’s own onboard pump, and the cable carries low-voltage power and control only.

ComparisonHow does the Triton PS compare to the E70 if I want wall and waterline coverage?

The E70 adds Wi-Fi app control and a dedicated waterline cycle. The Triton PS is deployed by hand, with the cycle chosen on the power supply unit and no app layer. Both climb and clean walls. The Triton PS listed at roughly half the E70’s price, though it is now discontinued and the E70 remains in the current line.

OperationIs the Triton PS still in production, or should I expect the model to be discontinued?

It has been discontinued. Maytronics has moved this segment to the Dolphin ACTIVE line, and retailers now list the Triton PS as sold out or refurbished only. Replacement parts and filter cartridges are still stocked by pool parts retailers, so an existing unit remains serviceable.

OperationWhat can the operator adjust on the Triton PS?

Everything is set on the poolside power supply unit: on/off, cleaning cycle selection and a weekly timer. There is no pressure adjustment, no surface-type setting and no app. Once a cycle starts, the unit runs it to completion.
