eufy · on the market since December 2024
Consumables: a 2.5 l dust bag in the station.
Suction and brushes 2 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.
- 8,000 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.

Mopping 3 facts
- Mop type
How the mop is built: flat pads, two spinning discs or a roller. Discs press harder on dried-on dirt, a roller rinses itself while it works.

- Mop lift on carpet
How far the robot lifts the mop when it drives onto a carpet. From about 0.4 in (10 mm) a medium pile stays dry.
- 0.5 in (12 mm)

The robot returns to the dock during a run to rinse the mop, instead of pushing dirty water around.
- yes
Dock 11 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.

How much the dust bag in the dock holds.
- 2.5 l
- Washes the mop
The dock washes the mop for you, so you do not rinse it by hand.
- yes

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
- Dispenses detergent
The dock mixes detergent into the water itself, from its own bottle.
- yes
- Plumbing hookup
The dock can be connected to the tap and the drain, so you never fill or empty a tank. It does need a connection nearby.

The clean water tank in the dock, which wets the mop.
- 3 l
- Dirty water tank
The tank that catches the dirty water from the mop. You empty this one yourself.

- 26.4 in (67 cm)
Navigation and obstacles 4 facts

- built-in LiDAR, no 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.
- AI camera

- 63 dB
Battery 2 facts
- Battery capacity
The capacity of the battery. It hints at the runtime, but how much the robot draws counts just as much.
- 4,600 mAh
- Runtime per charge
How long the robot cleans on one charge, at its quietest setting. After that it recharges and carries on where it stopped.
