Quick Answer: The Ecovacs Ultramarine P1 ($499.99-$660 depending on bundle) is Ecovacs’ first-ever robotic pool cleaner — a notable entry since Ecovacs is better known as a robot-vacuum brand (a direct Roborock/iRobot rival) now crossing into pool robotics. It delivers 4,800 GPH suction, dual-layer 3-micron filtration, and SmartNavi navigation, but reviewers genuinely disagree on whether it cleans the waterline: retailer listings claim full floor-wall-waterline coverage, while an independent hands-on test found it skips the waterline and that wall-climbing depends on surface texture.
Robot-vacuum brands moving into pool cleaning is a real 2026 trend — Ecovacs got there first with the Ultramarine P1, and Roborock has since announced its own first pool robot (the RockAqua P1, debuted at IFA 2026, not yet available in the US). Here’s what Ecovacs’ first pool-cleaning attempt actually delivers, and where the marketing claims and independent testing part ways.

Ecovacs Ultramarine P1
- Ecovacs' first-ever robotic pool cleaner — built by a company best known for robot vacuums, not pool gear.
- Four synchronized roller brushes scrub floor and walls, with dual-layer 3-micron filtration you can empty mid-cycle.
- IP68-rated, ~23 lb dry, with an included return hook to help lift it out of the water.
- 2-year warranty, but waterline coverage is genuinely disputed between retailer listings and independent testing — check the FAQ before assuming full coverage.

By the numbers
- Suction: 4,800 GPH — identical to Aiper’s own floor-only Scuba V3, placing the Ultramarine P1 squarely in the mid-tier of this site’s coverage, not flagship territory.
- Runtime: Ecovacs advertises up to 180 minutes, and a Basic Tutorials hands-on test in Germany confirmed roughly 3 hours in Eco mode — one of the few specs on this robot that independent testing and marketing actually agree on.
- Weight: ~10.5 kg (~23 lbs) dry. The same German review flagged this as genuinely double-edged: easy to lower into the pool, but a real workout to lift back out — especially still full of water — which is exactly why Ecovacs ships a dedicated return hook rather than relying on the handle alone.
- Filtration: Dual-layer 3-micron filtration in a basket Ecovacs says can be emptied mid-cycle without interrupting the cleaning run, a convenience feature several of this site’s reviewed Aiper/Beatbot flagships don’t offer at this price.
The waterline disagreement, explained
This is the most important thing to know before buying: retailers and independent testers don’t agree on what the Ultramarine P1 actually cleans.
Multiple Australian and New Zealand retailer listings (Harvey Norman, JB Hi-Fi, The Good Guys) describe the robot as cleaning the pool bottom, pool wall, AND waterline — the same full-coverage claim you’d expect from a flagship all-surface cleaner. But Basic Tutorials’ independent hands-on review reached a different conclusion: the P1 skips the waterline, and whether it climbs walls at all depends on the pool’s surface texture — smoother surfaces work better than rougher ones, a limitation retailer copy doesn’t mention.
This is a newly launched first-generation product from a brand with zero prior pool-robot track record, so some disagreement between marketing copy and real-world testing isn’t surprising. The practical takeaway: if waterline scum removal is your main reason for buying a robotic cleaner, verify current coverage claims (and ideally your own pool’s wall surface compatibility) before buying, rather than assuming the retailer-listing version of events.
Who should buy the Ecovacs Ultramarine P1
Buy it if you want a budget-to-mid-tier cordless floor-and-wall cleaner from a major electronics brand, and you’re comfortable being an early adopter of that brand’s first pool-specific product — Ecovacs’ track record is in robot vacuums, not pool gear, so there’s less of a multi-generation history to lean on compared to Dolphin, Aiper, or Polaris.
Skip it, or wait for more independent reviews, if waterline cleaning is a must-have: the disputed coverage claim is a real risk at this price point. Buyers who specifically need confirmed floor+wall+waterline coverage from a cordless robot may be better served by the proven Aiper Scuba X1, which this site’s own testing-sourced research confirms covers all three zones at a similar price tier.
Ecovacs Ultramarine P1 vs. the established cordless field
| Model | Cleans | Suction | Runtime | Price |
|---|---|---|---|---|
| Ecovacs Ultramarine P1 | Floor, walls (waterline disputed) | 4,800 GPH | Up to 180 min | $499.99-$660 |
| Aiper Scuba V3 | Floor only (confirmed) | 4,800 GPH | Up to 210 min Eco | ~$1,199 list |
| Aiper Scuba X1 | Floor, walls, waterline | 6,600 GPH | 180 min | $949.99 MSRP |
| WYBOT C1 | Floor, walls, waterline | N/A | Up to 110 min | $429.99-$569.99 |
The honest read: on paper the Ultramarine P1 undercuts most of this site’s established cordless lineup on price while matching the base Scuba V3’s suction rating — but every established rival in this table has a confirmed, undisputed coverage claim, and the Ultramarine P1 doesn’t yet. That’s the real cost of buying a first-generation product: the hardware spec sheet looks competitive, but the independent-review track record that would resolve the waterline question is still thin.
The bottom line
The Ecovacs Ultramarine P1 is a notable launch — a major robot-vacuum brand’s first serious attempt at pool cleaning, with genuinely competitive mid-tier specs (4,800 GPH, dual-layer filtration, IP68 durability) at a price that undercuts most established cordless rivals. But as a first-generation product, its most important coverage claim — does it actually clean the waterline — is disputed between retailer marketing and independent testing. Worth watching, and reasonable for budget-conscious buyers who mainly need floor-and-wall cleaning, but not yet the clear pick over proven options like the Aiper Scuba X1 if full all-surface coverage is non-negotiable.
