Facts as the maker states them. A dash means the maker does not name it. Each model’s page gives the source of every fact. Noise is the maker’s own figure, so we do not judge it, and a customer rating only counts from 20 reviews. * Foreign shop: delivery cost and VAT to the Netherlands estimated.
Eureka J12 Ultra specifications
The numbers that matter first, then every fact by group. As published by the maker or the shop we read it from.
Eureka · on the market since April 2024
Consumables: a 3 l dust bag in the station.
Dimensionsrobot and dock
From the published dimensions. The dock needs a spot 41 cm wide and 38 cm deep.
Suction and brushes 4 facts
- Suction power
Suction in pascal, as the maker measures it. More pascal helps on carpet, but it says little about how well the robot picks grit off a hard floor.
- 5,000 Pa
- Anti-tangle brush
A brush that guides hair to the side instead of letting it wind around the shaft. It saves the cutting work in homes with long hair or pets.
- yes
- Carpet detection
The robot notices when it drives onto a carpet. Most then raise their suction, and a mopping robot lifts its mop or leaves it at the dock.
- detects carpet
- Suitable for pet hair
Whether the robot copes with pet hair: a brush that hair does not wind around and a dock that empties the bin for you. Where the maker does not say so itself, we read it from those two.
- yes
Dock 7 facts
- Empties the dust bin
The dock empties the robot’s dust bin, usually after every run. You only empty the dock’s bag or bin.
- yes
- Bagless
The dock collects dust in a bin instead of a disposable bag. No bags to buy, but you empty it yourself.
- no
- Dust bag capacity
How much the dust bag in the dock holds.
- 3 l
- Washes the mop
The dock washes the mop for you, so you do not rinse it by hand.
- yes
- Dries the mop
The dock dries the mop afterwards, so it does not sit there wet and start to smell.
- yes
- Hot-air drying
Drying is done with warm air instead of cold. It is faster and it helps against smell.
- yes
- Dock size (w × d × h)
The width, depth and height of the dock. Measure the spot you have in mind, and leave room for the lid and for the robot driving in.
- 41.2 × 37.9 × 56.7 cm
Navigation and obstacles 2 facts
- Navigation
How the robot maps your home and follows that map. Lidar measures with a laser and works in the dark, a camera looks along and recognises more.
- LiDAR turret
- Obstacle avoidance
How the robot sees loose things on the floor, such as cables, socks or a pet accident. A camera with depth sensing sees more than a bumper that reacts on contact.
- 3D sensor (structured light)
Robot 1 fact
- Robot height
How tall the robot is. It decides whether it fits under your sofa, bed or cabinet.
- 10.8 cm
Battery 1 fact
- Runtime per charge

- 150 min
Smart features and warranty 1 fact
- Voice assistants

- Google Assistant
