The Eureka J15 Max Ultra flagship robot vacuum shows solid cleaning in the test, but clearly falls behind top models from Roborock, Dreame and co. in terms of obstacle detection and innovation.Marcus Schwarten (translated by DeepL / Marcus Schwarten) Published 🇩🇪
Eureka J15 Max Ultra test summary: Solid flagship without highlights
The Eureka J15 Max Ultra cleaned well in the test without keeping up with the best in its class. This also applies to obstacle detection, where even some significantly cheaper models now perform better. Navigation was reliable, as was the work of the station - albeit louder than that of some competitors.
Overall, the performance and features of the Eureka J15 Max Ultra are absolutely solid, but without any real highlights. Many other models already offered more in certain areas at the market launch in mid-2025, but some of them were also a little more expensive. The test candidate can no longer really keep up with the models from fall 2025 and early 2026, especially as its price has not fallen sustainably over time. It's time for Eureka to follow up with a new flagship robot vacuum in 2026...

Table of Contents
The Eureka J15 Max Ultra is the current flagship model in Eureka's robot vacuum portfolio, but has already been around for a few months. The manufacturer is not one of the biggest robot vacuum brands and is much less well-known than Roborock, Dreame or Ecovacs.
This makes it all the more exciting to find out what the current top model can and cannot do and how it compares to the competition. Our review of the Eureka J15 Max Ultra provides the answers - also in relation to other flagships from the past twelve months.

Features: Flagship without highlights
The Eureka J15 Max Ultra is a robot vacuum with the classic two rotating mops for the mopping function. The model has a suction power of 22,000 Pa, which is a solid but not outstandingly high value for a 2025 flagship model. What's more important, however, is how much of it reaches the floor - more on that later.
Thanks to the extendable side brush, which here looks like a claw with three fingers, and the mop that extends out of the side of the housing, Eureka promises cleanliness right into corners and along edges. It navigates with the so-called IntelliView AI 2.0, which is also used for obstacle detection and consists of a non-retractable laser tower on the robot and a camera module in the front. The equipment also includes dual disentangling technology and threshold crossing up to 45 mm.
The Eureka J15 Max Ultra is supplied with a self-cleaning station. In addition - apart from the lack of automatic detergent dispensing - the mops are cleaned as usual with water heated to 80°C and then dried with air heated to 55°C. Visually, the base has a rather simple and appealing design. What tarnishes the look somewhat in our eyes is that the white version has a black power cable.
The scope of delivery is manageable. Apart from the robot and station, there are no additional accessories apart from a spare dust bag and a small tool with a brush and hair clipper.
Set up & app: Smart app with many functions
The Eureka app is immediately appealing with its dark design and purple highlights. Establishing a connection between the robot, app and Wi-Fi also worked smoothly in the test and can be done either via the QR code under the cover or by searching for the device.
This is followed by the usual mapping run for all robot vacuums. Here, the J15 Max Ultra creates a virtual map of its "new territory" within a few minutes. The automatic room division did not work particularly accurately. Among other things, a window closed by a roller shutter was assumed to be another room behind it based on the reflection. However, most of the inaccuracies can be adjusted to the actual conditions via the map management, including restricted zones, thresholds, flooring and furniture. Overall, however, we liked the map customization better with one or the other manufacturer, also thanks to the sometimes quite long loading times of the app.
However, Eureka is in no way inferior to the market leaders when it comes to the available cleaning settings. In addition to the four standard modes "Vacuum and mop", "Vacuum and then mop", "Mop" and "Vacuum" for complete cleaning, rooms and zones, there is also the option of individual settings for each room as well as an AI mode with automatic adjustment. The cleaning power can be adjusted in four strengths (Quiet, Standard, Turbo, Max), the mopping moisture in 30 levels and the path setting in three options (Coarse, Normal, Fine). The cleaning sequence can also be set. All standard for models in the upper price range, but important.
Numerous setting options appear in the menu at the top right. In addition to cleaning scheduling and protocols, there are the usual and important customization options for cleaning (including individual settings for individual carpets), AI obstacle detection, the station and more. We were irritated by the fact that access to the live video transmission worked without prior activation including a security code. We also missed voice control. There is only a German voice feedback.
Navigation & obstacle detection: surprising weakness
The rigid laser tower on the top is not quite up to date for the price range. Nothing against the established LiDAR technology. But a retract function to flatten the 11 cm high robot for driving under furniture would be beneficial for comprehensive cleaning. Other flagship models from the recent past offer better results here. The Eureka J15 Max Ultra took around 40 minutes to cover 25 square meters in the test, which is solid.
The navigation itself worked reliably overall, even in the tangle under a dining table. Here, however, it occasionally came into slight contact with thin, black chair legs. This was not the only problem with obstacle avoidance. A sock lying around was occasionally picked up. The Eureka J15 Max Ultra completely overlooked a loose shoelace on the floor during the test and "swallowed" it until it came to a standstill. However, this has also happened to others.
The obstacle detection failed to detect other small obstacles such as a 3x3 cm toy brick. Others have done better. A tile half as high was run over by the robot and in the end even blocked the roller, so that the cleaning was aborted. Overall, we expect a little more from a flagship in this price range with modern camera technology and AI.
Another problem arose when returning to the base station. This is where the Eureka J15 Max Ultra completely fails in the test and shows the problem known from Ecovacs. Obstacles were simply driven over, as Eureka apparently also shuts down obstacle detection on the return journey. Even much cheaper robot hoovers can do this much better. In addition, the pure driving noise is relatively loud.
Cleaning performance: Solid
Decent suction power
On smooth floors, the Eureka J15 Max Ultra made a good impression in the test, as far as navigation and height led it there. But anything else would be a disappointment. On carpets with a medium-length pile and standard suction power, however, not all the dirt was picked up, but a relatively large amount of sand grains from the test dirt remained in the carpet fibers. Other robot vacuums in the test have already done this more thoroughly. At the highest suction power, however, the Eureka J15 Max Ultra also achieves a good, but not perfect result, which of course comes at the expense of battery life and noise levels.
Typical mopping performance
For mopping, Eureka relies on the established two rotating mops in its flagship model. This mopping technology is now overshadowed by the mopping roller, which is now even used in many significantly cheaper and brandnew mid-range vacuum robots such as the Ecovacs Deebot T90 Pro Omni or the Mova S70 Roller. Everyday dirt was picked up as far as possible. However, like many other models with this mopping technology, the robot reaches its limits with dried-on stains - even after repeated cleaning. Many mop roller models are superior here. The performance is sufficient for everyday dirt.
Good corner cleaning and anti-hair tangling
Corner cleaning with the extendable side brush worked well apart from a tiny amount of sand grains. The extendable mop also mostly cleaned quite close to skirting boards, furniture and the like. There is little to criticize here. The same applies to the anti-hair entanglement function, which worked reliably and is activated when you return to the station. Incidentally, it also cleans itself, which works well.
Battery life & power consumption: economical, but relatively loud
Like all candidates, the Eureka J15 Max Ultra had to clean 50 square meters in the test with standard settings (standard suction power, mopping moisture 20, standard route). The robot used up a good 40 percent of its 6,400 mAh battery. This means that a good 100 square meters are realistic with one battery charge.
If the robot vacuum and mop performs this 50 square meter cleaning once a day, our measurements show an electricity consumption of around 9 kWh - including the complete preparation in the station and the standby consumption during the "idle" time. This makes the Eureka J15 Max Ultra energy-efficient in the test.
In standard suction mode, including mopping, we measured the robot at around 60 dB (from a distance of 1 m). In self-cleaning mode, the station occasionally emits up to 68 dB, and even up to 73 dB for short periods during suction. Other flagship robot vacuums are sometimes quieter here, even when drying the mop pads for several hours at around 39 dB. This is particularly annoying when the robot vacuum is in the living area and not in a storage room or similar.
