Long hair is the enemy of every robot vacuum cleaner – after a week, there is usually a ball of felt hanging from the main brush that has to be painstakingly removed. The 3i P10 Ultra promises a remedy with a hidden TangleCut blade. It also has a suction power of 18,000 Pa and an extendable UltraReach mop for cleaning corners. The 3i brand, which has been active since 2016 and already sold millions of units in 2024, is attacking established giants such as Roborock and Dreame for an RRP of 799 euros. After around 100 test drives and a week of continuous use, we show what the 3i P10 Ultra can really do in the test – and where its limits lie.

Scope of delivery and workmanship: Compact but heavy
The scope of delivery is neatly organized: The robot comes in its own box, while the mops, cleaning tools, cleaning fluid, drive-in ramp and cable are stowed in a second box. The base station stands firmly in the main box and is only surrounded by a plastic bag.

The gray housing stands out from the usual standard black and looks more valuable than expected. The workmanship is clean, and the station in particular stands out positively: While Dreame and Roborock erect veritable towers, 3i sticks to reasonable dimensions.
At 4 kg, the robot itself is noticeably heavier than the competition, but also feels more robust. The large wheels and the massive main brush promise durability. The higher weight also ensures better ground contact and improved traction – the wheels are pressed more firmly onto the ground, which benefits the climbing performance. Only the 10 cm height could be a problem with low furniture.
Setup in the test: The 3i P10 Ultra is ready to go in around 15 minutes
The assembly is really quick: plug in the brush and mops, fill up the fresh water tank, plug in the cleaning agent until it clicks, plug in the power connection and click the retraction ramp onto the base – it takes less than 5 minutes. Everything fits together perfectly and the mechanics feel solid. When setting up the station, you should leave about one meter of space at the front for the robot to maneuver and 50 cm at each side.
The setup is a positive surprise: scan the QR code with your cell phone, enter the Wi-Fi password and you’re done. In under 10 minutes, the P10 Ultra was up and running and ready for mapping – which is how it should work with any smart home device.
The first mapping in the 3i P10 Ultra test takes about 10 minutes for a 50m² apartment. The result is convincing: The 2D map is largely accurate, the 45-degree 3D perspective helps to understand the room layout. Furniture is recognized correctly, even complex room shapes pose no problem.
Navigation and obstacle detection: Clever, but with flaws
The triple sensor combination of LiDAR, 3D camera and AI system works with impressive precision and reliably detects cables, which are then marked as obstacles in the app. Particularly practical: LED lighting switches on automatically in the dark so that the camera can also navigate and detect obstacles at night without any problems.
The live camera function was particularly entertaining, allowing us to observe our own dog from a robotic perspective – definitely one of the highlights of the test week.

The system’s memory is also practical, as the P10 Ultra remembers detected obstacles such as cables, shoes or toys for future journeys and notes them on the map. This saves time and prevents blockages, but it also brings with it the first noticeable weakness. The obstacle detection works too carefully and keeps a safety distance of around 3-4 cm around cables, leaving spots or dirt within this radius uncleaned – particularly annoying when crumbs from breakfast land right there.

Low obstacles, on the other hand, are a strength, as the P10 Ultra easily overcomes door thresholds of up to around 2.4 cm – an above-average value for a robot without special climbing functions. The large wheels help noticeably and enable it to keep up with the established competition.
Suction power of the 3i P10 Ultra in the test: three levels, noticeable differences
The advertised 18,000 Pa are more than just numbers on paper – they are tangible. The three power levels differ significantly from one another: Level 1 is sufficient for light soiling and is pleasantly quiet. Level 2 is the standard for normal cleaning. Level 3 is impressively thorough, but also correspondingly loud.
The strength of the system is particularly evident on carpets. The ultrasonic detection works reliably and automatically increases the suction power. Even deep-seated dirt in high-pile carpets is picked up, while the mops are raised by 10.5 mm – sufficient for most carpets. This automatic adjustment forms the bridge to the second core function of the P10 Ultra.
UltraReach mop: edge solution with potential for improvement
When mopping, the P10 Ultra relies on its extendable mops, which are a clever technical solution. One of the two mops extends automatically to reach edges and corners, while the intensity can be adjusted via the water flow in the app. The system works noticeably better than fixed solutions, but does not achieve the perfection of a mop roller.
In the corners, a 2-3 mm wide strip usually remains uncleaned – much better than the usual 1-2 cm, but not perfect. Perfectly adequate for everyday use, even if those who love detail occasionally have to clean up.
The general wiping performance is solid and reliably removes everyday dirt, while dried stains sometimes need a second pass. In over 100 test runs, visible streaks only remained on the laminate 1-2 times – a very good rate.
TangleCut system of the 3i P10 Ultra: it worked perfectly in the test
The TangleCut system does not work in the brush itself, but in the cleaning station. When the robot returns after the job is done, a small slider in the station automatically frees the main brush from tangled hair. After a week with a dog in the household and long human hair, the verdict is clear: The system really works.

What normally looks like a ball of felt after a week remains mostly loose. The brush was significantly cleaner than all other robots tested. Nevertheless, you should take the brush apart every few weeks and remove the last remnants – this technique doesn’t work miracles either.

App control: Functional with charming quirks
The 3i app offers all the important functions: Map management, cleaning planning, no-go zones and schedules. The user interface is largely intuitive and response times are acceptable. The live camera can also be activated without any problems.
Particularly amusing are the translations, some of which have a Rhenish touch – the robot is then “wiping”, “cleaning” or “charging”. Other testers find the “clumsy translation” more annoying, but we found it rather charming and had to smile. Functionally, everything is there, even if some untranslated terms do creep in. 3i could make improvements here, but it doesn’t really affect use.
All-in-one station: 70 days maintenance-free?
The maintenance station does its job thoroughly and reliably. After each use, the mops are washed with hot water at 60°C and then dried with warm air. Odors or bacterial growth are therefore no longer an issue.
The automatic dust emptying works without any problems, and according to the manufacturer, the 3-liter bag should last around 70 days with normal use.
The detergent dosage is also fully automatic. The generously dimensioned 4-liter water tanks make frequent refilling of fresh water and emptying of waste water superfluous.
One small drawback is the appearance: The matt black bucket lids are very susceptible to water drop marks. After the first wash, they look stained and unattractive. Drying becomes a must if you value the look.
Practical: The mops can also be thrown into the washing machine if necessary. The Velcro fastener is very strong and the counterpart sits on the mop itself so that nothing gets caught in it. The only downside is the matt black bucket lids, which are very susceptible to water drop marks – it makes more sense to dry them after cleaning than to air dry them.

Weak points: Where the 3i P10 Ultra weakens in the test
After intensive use, several weaknesses crystallize. The most serious weakness is probably (as with many robot hoovers with extra mops): larger puddles of spilled liquids should be picked up manually beforehand. The rotating mops, for example, spread drinks or the like rather than picking them up. Mop roller systems are clearly superior here.
The 5 cm safety distance around detected cables also leaves dirt in the immediate vicinity. In very tight corners, jamming occasionally occurs – the 10 cm height and the sensor system, which does not fully cover 360°, lead to navigation problems in some situations.
Suitability for everyday use: Solid partner with limitations
After a week, it is clear that the P10 Ultra is a solid everyday helper for structured households. If you don’t have any extreme obstacles and can live with occasional rework, you have a reliable cleaning partner.
The TangleCut system alone justifies the purchase for households with long hair or pets – the time saved on brush detangling is considerable. The suction power is completely convincing, the mopping function is in the good mid-range.
What about the competition?
In the 800-euro class, the P10 Ultra is up against established names such as the Roborock S8 Pro Ultra, Dreame L40 Ultra and Ecovacs X2 Omni. These offer similar features with more mature ecosystems and better apps.
The P10, on the other hand, scores points with its functioning TangleCut system and compact station. The suction power is on a top-class level and the price is fairly calculated. It shares some of its weaknesses when it comes to liquids and the cautious safety distance around cables with the competition already established on the German market.
Conclusion: Well thought out, but not entirely without weaknesses
The 3i P10 Ultra is more than just another robot with big promises. The TangleCut system really works and solves a real problem. The UltraReach function noticeably improves edge cleaning. The 18,000 Pa suction power is not just impressive on paper.
The weaknesses lie in the handling: problematic liquid pick-up, the cautious safety distance around cables and perhaps, on a side note, the app translations that could be improved. With its dimensions, it certainly looks a little clunky, but it also has a high-quality finish.
Recommended for anyone who struggles a lot with hair, needs a compact station or simply wants to try something different from the usual suspects. The P10 Ultra proves it: Even lesser-known manufacturers on the German market can challenge established brands – if the technology is right.
VORTEILE
- with TangleCut system a unique hair-cutting technique in the station
- extendable mop for better edge cleaning
- the compact station is significantly smaller than competitors with full equipment
NACHTEILE
- Spilled liquids are spread rather than absorbed
- 3 to 4 cm safety distance around cable leaves dirt behind
- Rather clunky design
Fazit
The 3i P10 Ultra impresses with its innovative TangleCut system and very strong suction power, but is weaker with liquids and overly cautious obstacle detection. A real alternative to established brands for households with hair problems.
