Ecovacs Deebot T20 Omni specifications

Ecovacs · on the market since June 2023
Consumables: a 3 l dust bag in the station.
Dimensionsrobot and dock
From the published dimensions. The dock needs a spot 45 cm wide and 43 cm deep.
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.
- 6,000 Pa
- 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
Mopping 2 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.
- spinning pads
- Mop lift on carpet
How far the robot lifts the mop when it drives onto a carpet. From about 10 mm a medium pile stays dry.
- 9 mm
Dock 10 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
- Wash temperature
How hot the dock washes the mop. Above 60 °C grease comes off, which is what keeps a mop from smelling.
- 55 °C
- 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
- Clean water tank
The clean water tank in the dock, which wets the mop.
- 4 l
- Dirty water tank
The tank that catches the dirty water from the mop. You empty this one yourself.
- 4 l
- 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.
- 44.8 × 43 × 57.8 cm
Navigation and obstacles 3 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

- Robot weight
What the robot weighs. It counts most if you carry it up a staircase every day.

- 300 ml
- Noise
The noise in decibels, in the setting its source names: makers mostly give the standard setting, shops often the highest. 65 dB is like a vacuum at half power, 55 dB like a conversation.
- 67 dB

- Battery capacity
The capacity of the battery. It hints at the runtime, but how much the robot draws counts just as much.
- 5,200 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.
- 260 min
Smart features and warranty 1 fact
