Ecovacs Ultramarine P1

Name: Ecovacs Ultramarine P1
Brand: Ecovacs

One reviewer watched it climb every wall and leave its pool spotless in about 90 minutes. In another's test, on pebblecrete walls it sometimes let go and drifted down, and it has to be hooked out with a pole after every run.

Autonomy Ladder

Why Level II.

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.
IIIConditional AutonomyFinishes whole jobs in familiar spaces; struggles at the edges.
To reach Level IIIMost sessions finish without intervention. Rescue is occasional, not routine.
IIAssisted AutonomyThis robot

Ecovacs Ultramarine P1 runs preset routines on its own, and the owner is its recovery system.

Navigation and control

SmartNavi route planning with IMU sensor
Why this level
- An IMU plans routes across the floor, walls and waterline without a stored map, and the robot starts, cleans and parks near the edge on its own.
- A person drops it in, lifts it out with a hook and recharges it for about 4 hours each time, which holds it at Level II: Assisted Autonomy.

CapableAt or above 45% of the 450 robots we scoreand 68% of the 65 scored robot pool cleaners

DeficientLimitedCapableStrongExemplary

Measured on 8 of the 9 inputs14% not counted

Our assessment did not establish an independent source for software stability on this machine, so that input is 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 score69What it does without you.

Task completion16% of the score78

Evidence

Pool cleaners: EFTM reports its pool spotless in about 90 minutes with every wall climbed, and Digital Reviews found floor debris gone after about two hours across repeated runs; wall cleaning was mixed on Digital Reviews' pebblecrete.

Coverage and navigation10% of the score68

Evidence

Pool cleaners: EFTM watched it cover the floor at least twice and climb every wall; Digital Reviews found the IMU route looked illogical but gave consistent results. No map is retained between runs.

Edge-case recovery10% of the score58

Evidence

Pool cleaners: EFTM saw one backflip after which it travelled upside down across the pool, which it calls a one-off; Digital Reviews had one run end with the battery flat while still underwater. It usually parks near the edge.

Operating envelope4% of the score64

Evidence

Pool cleaners: it handled EFTM's two-tier steps and Digital Reviews' large pebblecrete pool, but walls on that surface were inconsistent, and the manual excludes steps, shelves under 50 cm and depths outside 0.5 to 3 m.

Dependability40% of the score67Whether it keeps doing it.

Field failure rate16% of the score70

Evidence

EFTM over a few weeks in July 2026 and Digital Reviews over repeated uses through August report no hardware failure.

Software stabilitynot countedno source verified65

Evidence

The manual lists an OTA upgrade state for the robot; no independent report of what an update changed on this model was found.

Support longevity10% of the score62

Evidence

Scored as commitments: Ecovacs' US store sells outer and inner filter baskets, roller brushes and climbing ring assemblies for the P1, and the manual documents owner replacement of tracks, brushes and the bottom scraper. No update commitment is published.

Ownership burden20% of the score60What it asks of you.

Routine maintenance12% of the score52

Evidence

Per the manual, the owner lowers it in, lifts it out with a pole hook, rinses both filter baskets after every run, charges it for about 4 hours, clears the impeller every 3 to 4 months and stores it charged off-season; EFTM found fine dirt hard to rinse from the 3-micron filter.

Consumables8% of the score72

Evidence

The 3-micron filter is replaced every 150 hours, and tracks, roller brushes and the bottom scraper are replaceable wear parts, per the manual; Ecovacs' US store sells filter baskets and brushes (priced by the consumables engine). No subscription is required.

middle half of the databaseits medianthis robot

Reported, not scoredneither measures how well the robot works

Five-year costNot costed

$499.99 at launch and on Ecovacs' US store, no subscription; the 3-micron filter is a 150-hour consumable, so pool-season hours set the running cost.

Data postureCloud-optional

Full core function without an account; cloud adds convenience.

What leaves the homeDocumented

No camera or microphone is listed. The robot pairs with the Ecovacs Home app over Bluetooth above water for modes and schedules, and starts in Floor mode from its own power button. Ecovacs publishes no model-specific statement of what the app sends to its servers.

The record so far

Two hands-on reviews used it for weeks without a hardware fault. One flipped run, one flat battery underwater and inconsistent wall grip on pebblecrete are the documented issues.

Common questions

What people actually ask.

5 answered

OperationDoes the Ultramarine P1 climb out of the pool by itself?

No. It stops near the edge when it finishes or the battery runs out, and you lift it out with the supplied hook on a pool pole.

CompatibilityCan I watch the Ultramarine P1 clean from the app?

Not underwater. The Bluetooth connection drops once it submerges, per the manual and a hands-on review.

OperationWill the Ultramarine P1 clean my sun shelf?

The manual warns shelves or steps less than 50 cm below the surface can trap it, and says it was not designed for steps.

OperationHow long does the Ultramarine P1 take to recharge?

About 4 hours, per the manual. A hands-on review measured 3 hours 40 minutes from 5 percent.

OwnershipHow often does the Ultramarine P1's fine filter need replacing?

The 3-micron filter is a consumable Ecovacs recommends replacing every 150 hours of use.
