Eureka J15 Pro Ultra in the test: Strong suction power

The J15 Pro Ultra is one of Eureka’s top models and makes this claim clear through its size alone. The vacuum robot comes in a massive box that houses the vacuum cleaner and the massive base station. There is space for two water tanks (fresh and dirty water) as well as a dust bag.

Structure and furnishings

After unpacking, you first need to attach the mop and side brush to the bottom of the J15 Pro Ultra. The former are attached magnetically and can be easily clipped on and the side brush is also quickly attached. You attach the ramp to the base station and fill the tank with fresh water – the fresh water tank is light and transparent, the tank for dirty water is dark. This prevents any confusion.

No further preparation is necessary. The dust bag is already installed, the only additional accessory is a brush to remove hair if necessary. The vacuum robot switches on when it is pushed into the station for charging and immediately makes contact with the base station. You connect the vacuum cleaner to the WiFi using the Eureka app and can then control it via the app.

Detailed settings in the app

In a quick run, the J15 Pro Ultra creates a map of the apartment. To do this, he uses the LiDAR setup, which measures the environment with a laser. In the first run he captures the rough floor plan, which is done in just a few minutes. During the first cleaning trip, the map is made more precise.

In the Eureka app you can of course also edit the map, divide or combine rooms, define exclusion zones and virtual walls or adjust floor coverings. You can then start the cleaning process via the app. Alternatively, you can press the power button on the robot itself to send it off.

However, you have more control options in the app. You can have the J15 Pro Ultra clean the entire apartment or control individual rooms or zones. You can choose whether you want it to vacuum and mop, vacuum first and then mop, or just do one of the two. You can also specify areas in which it is not allowed to wipe; these will be left out during the wiping cycle.

You can also determine the suction strength and adjust how moist the mop should be. Recommendations are given depending on the floor covering; in the “Adjust” mode you can also set the preferences for each room individually.

Safe navigation with 3D obstacle detection

The Eureka J15 Pro Ultra cleans quickly and purposefully, and you can track its paths in the app. It is based on its LiDAR setup and cameras at the front. The high structure also ensures that it does not get under low furniture.

Thanks to 3D obstacle detection, it navigates gently around chair legs and other obstacles. However, it is better to put away loose carpets, cables and smaller objects. While the thin floor mats were only slightly moved and ultimately cleaned, a deep-pile carpet was simply pushed to the side.

From places that it cannot reach, such as under low furniture, it releases itself after a few attempts and does not get stuck unnecessarily. However, this also means that he sometimes leaves out areas. So he didn’t clean the kitchen in the first round because the space next to the table was apparently interpreted as being too narrow (the robot would have fit through without any problems). After moving the chair around a bit, it worked the second time.

The vacuum cleaner can drive over door thresholds as long as they are not too high. He can even extend the wheels a little to “climb” over the threshold. However, he was no longer able to free himself from the bathroom with a slightly higher threshold and finally called for help to get him back to the base station.

Strong suction power with up to 16,200 Pa

The great strength of the J15 Pro Ultra is definitely its suction power. The robot vacuum cleaner can achieve up to 16,200 Pa, although it requires significantly less power in standard operation. The default setting is more than sufficient for most tasks. The side brush collects dust and hair from corners and edges and feeds it to the main brush. Only a small egg shell was just pushed around and kept coming out from under the vacuum.

In suction mode with maximum power nothing remained left. Coarse crumbs and fallen debris in the kitchen as well as small stones in the hallway were also vacuumed up without any problems. With its strong suction power, the J15 Pro Ultra is also suitable for cleaning carpets.

A hair trimmer is also integrated into the cleaning brush. When the vacuum cleaner is back in the base station, any hair remaining in the brush is automatically trimmed. The Eureka J15 Pro Ultra is particularly suitable for households where people with long hair or pets live.

Slightly uneven when wiping

When wiping, however, a slightly more differentiated picture emerges. First of all, it should be positively emphasized that Eureka has further developed the J15 Pro Ultra compared to the Eureka J12 Ultra. The J15 Pro Ultra can now lift the mops and actually only mop where it is supposed to.

Another plus point is that the right mop can be folded out and therefore reliably cleans even edges. He approaches corners backwards again in order to reach them better. The wiping result is still somewhat uneven.

The mops are rinsed before starting the journey and the robot sets off with damp mops. At set intervals it returns to the base station to wash out. Although you can select the mop moisture in three levels in the app, we couldn’t notice a difference in practice. Initially, the mopping is very damp, but as the mopping process progresses, the mops become increasingly dry and the cleaning performance decreases. An average would be ideal, especially since the mops clean well.

This is our tip: It is better to avoid sensitive floors that cannot tolerate too much moisture when wet cleaning and to specifically target rooms that need to be mopped properly.

Fully automatic cleaning in the base station

When the J15 Pro Ultra has finished working, it returns to the base station, which takes care of the cleaning fully automatically. Hair that may have become caught in the brush is trimmed, the collected dust and dirt is sucked into the base station’s dust bag and the mops are washed with hot water.

The base station then carries out self-cleaning, sucks the dirty water into the container provided and dries the mops with hot air. The latter takes two or three hours depending on the setting. The mops are then clean and dry, which prevents mold and odors from forming.

So you basically don’t have to worry about cleaning. The manufacturer recommends cleaning the base station about once a month. The cleaning bowl for the mops can be removed. The mops themselves can be removed so you could occasionally put them in the washing machine.

Conclusion: Great suction power, compromises when mopping

The Eureka J15 Pro Ultra is a great everyday helper that can relieve a lot of housework. Thanks to the fully automatic base station, you don’t have to do much work yourself. The cleaning performance is very good, with the side brush and movable mop it cleans right up to the edges. The suction power of up to 16,200 Pa is phenomenal. The Eureka J15 Pro is ideal for carpets and, thanks to the hair cutting function, also for households with a lot of hair. However, you have to make compromises when mopping; it is not the first choice for sensitive floors.

With an RRP of 1,099 euros, the Eureka J15 Pro Ultra is not cheap. However, he is there for Black Friday Media Markt and Saturn on offer for 679 euros. At this price, the vacuum-mopping robot with self-cleaning base station is a full recommendation.
