Dolphin Triton PS Automatic Robotic Pool Vacuum Cleaner, Alw
✅ PROS
- Active scrubbing brush tackles algae and stubborn film on walls and floor, not just loose debris
- AlwaysClean technology means no charging cycles — just drop it in and let it run for hours
- Filter basket is easy to empty with a quick rinse; no messy bag changes
❌ CONS
- No remote or app control — you get one cleaning mode, and that's it
- Several owners report premature motor failures within 12-18 months, often past warranty
- Doesn't climb walls — only scrubs them at the waterline, so upper walls need manual attention
The Verdict
The Dolphin Triton PS isn’t trying to be everything. It’s a workhorse that does one thing — scrub your pool floor and lower walls — and does it without ever needing a charge. That “AlwaysClean” pitch is genuinely compelling if you’re tired of babysitting a robot. But with a 3.9-star average across 195 ratings, the story isn’t that simple. Let’s break down what you’re actually getting.
What’s in the Box
You get the Triton PS unit itself, a 40-foot swivel cable, and a small filter basket. That’s it. No caddy, no remote, no wall-climbing module. The power supply is built into the cable plug, which keeps the above-ground footprint minimal. Assembly is genuinely five minutes — clip the cable, drop it in, plug it in. The unit is powered continuously, meaning it runs until you pull it out, not until a battery dies.
Performance and Build Quality
The Triton PS uses what Dolphin calls “active scrubbing” — a rotating brush that agitates surfaces rather than just sucking up loose debris. This matters. If your pool has that slippery film on the steps or algae patches on the floor, this robot will actually work them off, not just glide over them. In that regard, it outperforms cheaper suction-side vacuums that purely rely on water flow.
The cleaning pattern is algorithmic but not smart. It doesn’t map your pool; it just bumps around until it covers ground. For a rectangular pool, this works fine. For an odd-shaped or kidney pool, you’ll watch it miss corners and repeat the same lane over and over. Owners consistently note it takes 2-3 hours to do what a smarter unit does in 60-90 minutes. That’s fine if you run it overnight, less fine if you want a quick pre-party cleanup.
The AlwaysClean system is the headline feature, and it delivers. No charging dock, no battery degradation, no “oops, it died halfway through.” You plug it in, it runs until you unplug it. For pool owners who just want the water clear every morning, this is a legitimate convenience.
What Buyers Praise
The cleaning power gets real love. One verified buyer put it plainly: “This thing scrubs better than anything I’ve owned. The algae line on my steps disappeared after two runs.” Another noted, “I’ve had mine for three years. It’s slow, but it’s consistent. I just leave it in overnight and wake up to a clean pool.” Filter maintenance is also a recurring plus — the basket pops out, rinses clean, and goes back in. No bags, no hoses to backwash.
Where It Falls Short
Here’s the honest part. The most consistent complaint isn’t cleaning ability — it’s longevity. Multiple reviewers report the motor dying between 12 and 18 months. One frustrated owner wrote: “Worked great for a year. Then it just stopped mid-cycle. Dolphin’s warranty process took three weeks and they still charged me for shipping.” That’s a real pattern, not a one-off.
Also, the “PS” in Triton PS stands for “Pool Shape” — it’s designed for pools up to 50 feet, and it does not climb walls. It scrubs the cove and waterline but doesn’t ascend. If your pool has significant algae above the waterline, you’ll still be brushing by hand. And there’s no remote, no app, no scheduling. You get one button. Some shoppers will see that as simplicity; others will see it as a $700 paperweight that can’t be directed to a dirty spot.
Who Should Buy This
Buy it if you have a straightforward in-ground pool (up to 50 feet), you want set-and-forget cleaning, and you’re okay with a slower, dumber robot that scrubs aggressively. It’s also a good fit if you hate dealing with batteries and charging schedules.
Skip it if you have a complex pool shape, want app control, or expect wall-climbing. Also skip it if you’re factoring in multi-year reliability — the failure reports are too frequent to ignore.
FAQ
Q: Does the Dolphin Triton PS climb walls? No. It scrubs the floor, coves, and waterline but does not ascend vertical walls. You’ll need a separate solution for upper-wall algae.
Q: How long does the cable reach? It ships with a 40-foot swivel cable. That’s enough for most residential pools up to 50 feet, but measure your distance from the outlet to the far end of the pool before buying.
Q: Is it really “never charging”? Yes. It’s corded and runs continuously off the power supply. There’s no battery to degrade or recharge. Just unplug it when you want it to stop.
The Verdict
Buy it if you want aggressive scrubbing power and hate charging batteries. The cleaning performance is genuinely strong, and the AlwaysClean design removes a whole class of hassles.
Skip it if you need wall climbing, smart navigation, or a device you expect to last beyond two years without a repair.
Rating: 3.7/5 — A capable cleaner with a real design flaw in durability. At this price, you’re gambling on the motor. If you win, it’s great. If you lose, you’ll be calling support.
