Robot vacuums have spent years making indoor cleaning feel a little less annoying. You set a schedule, let the robot do its thing, and hopefully spend less time chasing dust around the house. Now Ecovacs is trying to bring that same idea outside with the Ultramarine P1, its first robotic pool cleaner.
The Ultramarine P1 was first shown at CES 2026 and is now available in the U.S. through Ecovacs and Amazon for $499.99.
That puts the P1 in a more approachable price range than many high-end robotic pool cleaners, some of which can easily climb past $1,000. But Ecovacs is also entering a crowded category, with established names like Aiper, Beatbot, Dolphin, and Mammotion already competing for pool owners’ attention.
At its core, the Ultramarine P1 is a cordless robotic pool cleaner designed to scrub and vacuum pool floors and walls without being tied to a power cable while it works. It can handle different pool surfaces, including fiberglass and pebble-stone, and clean pool floors, walls, platforms, and slopes.
The biggest number Ecovacs is promoting is suction. The P1 uses what the company calls 4800GPH UltraPure Suction, along with an S-flow anti-clog channel, to pull in leaves, sand, dirt, and smaller debris.
Here, the idea is simple: pool cleaners need enough suction to handle the stuff people actually find in pools. That might be fine dust one day and leaves after a windy afternoon the next. The anti-clog design is there to help the cleaner keep moving instead of getting jammed up when debris sizes vary.
The filtration setup is also worth a look. The P1 uses a dual-layer filter with a 180-micron outer mesh and a 3-micron inner filter. In everyday terms, the outer layer is meant for larger debris like leaves and grit, while the finer inner filter is there for smaller particles such as pollen.
Ecovacs says the system can capture more than 10 types of debris and deliver up to 99 percent pickup efficiency. As always with pool cleaners, real-world results will depend on the pool’s shape, the amount of debris, and how often the filter is emptied and rinsed.
Here are the main specs Ecovacs is highlighting:
Suction is important, but navigation might be the more interesting part of the Ultramarine P1. A lot of simpler pool cleaners still move in a fairly random pattern. They travel around the pool, bump into surfaces, change direction, and eventually cover most of the area.
Ecovacs is taking a more robot-vacuum-style approach. The P1 uses the company’s SmartNavi Intelligent Navigation System, which relies on an IMU sensor to track movement and plan cleaning routes. Ecovacs says the robot can reach up to 99 percent floor coverage while reducing repeated passes.
That matters because pool cleaning is not just about whether a robot can move. It is about whether it can move in a predictable enough way to finish the job before the battery runs down. Better route planning can also help avoid the familiar “missed corner” problem, where a cleaner does a decent job overall but leaves one section looking untouched.
The P1 also uses four independently operated roller brushes at the front and rear. Those brushes are designed to help with traction, turning, and surface contact, especially when the cleaner moves from the pool floor to the wall or deals with slopes and uneven surfaces.
Of course, awkward pool shapes can still be tricky. Steps, ledges, sharp corners, and deep-end transitions can challenge even more expensive pool robots. That is something buyers will want to keep in mind.
The Ultramarine P1’s 5,200mAh battery can run for up to three hours in Eco mode. The listed cleaning coverage is up to 180 square meters, or roughly 1,938 square feet, on a single charge.
For many residential pools, that should be enough for a standard cleaning session. But pool size is only part of the story. A simple rectangular pool with light debris is a very different job from a pool with steps, slopes, ledges, and a pile of leaves after bad weather.
The cordless design is one of the P1’s more convenient features. There is no floating cable to manage, no cord to untangle, and less setup before each cleaning cycle. The trade-off is that the robot needs to be charged, removed from the water, emptied, and cleaned between uses.
In other words, it can reduce the work, but it does not make pool maintenance disappear completely.
The Ultramarine P1 works with the Ecovacs Home app, which gives users access to scheduling, three cleaning modes, and adjustable efficiency settings.
That should feel familiar to anyone who has used a modern robot vacuum. You can choose a cleaning mode, set a schedule, and manage the robot from your phone instead of walking over to the pool every time.
Still, pool robots are a little different from indoor cleaning robots. A robot vacuum usually docks itself, charges itself, and waits for the next run. A pool cleaner needs more hands-on attention. You have to lift it out of the water, clean the filter, and make sure it is ready for the next cycle.
So the app helps, but the physical maintenance still matters.
The Ultramarine P1 is a notable launch because it shows Ecovacs moving further beyond indoor cleaning. The company is best known for robot vacuums, but it has also pushed into window-cleaning robots and lawn care. Pool cleaning is another logical step because it is repetitive, time-consuming, and easy to put off.
The challenge is that pool cleaning is a very different environment from vacuuming a living room. The robot has to deal with water, changing debris, pool chemistry, slopes, walls, and outdoor wear. Ecovacs is pointing to features like an IP68 waterproof rating, multi-layer O-ring sealing, and a 10-tier durability system, but long-term reliability will be something buyers learn over time.
For now, the Ultramarine P1 looks like a practical first move into pool care rather than a luxury flagship. It brings strong suction claims, fine filtration, planned navigation, cordless operation, and app control into a product that launched at $499.99 and is already listed for less on Amazon.
That could make it appealing for pool owners who want something more capable than a basic cleaner but do not want to spend premium money on a top-tier model.
Ecovacs is not entering an empty market, and the P1 will need to prove itself against brands with more pool-cleaning experience. But the idea is easy to understand: take the robot-cleaning habits people already know from inside the home and apply them to one of the more annoying jobs in the backyard.
