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.
Price history
SwitchBot S20 specifications
The numbers that matter first, then every fact by group. As published by the maker or the shop we read it from.
SwitchBot · on the market since September 2025
Consumables: a 4 l dust bag in the station, which lasts up to 90 days.
Dimensionsrobot and dock
From the published dimensions. The robot passes under furniture with 12 cm of clearance or more.
Suction and brushes 3 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.
- 10,000 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
- Extending side brush
The side brush swings out in a corner or along a kickboard, so the dust there is swept in too.
- yes
Mopping 1 fact
- 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.
- roller mop
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.
- 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.
- 4 l
- Dust bag lasts
How long the maker says a dust bag lasts with daily use. With pets or a lot of carpet it is shorter.
- up to 90 days
- 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
- 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.
- yes
- Clean water tank
The clean water tank in the dock, which wets the mop.
- 2.7 l
- Dirty water tank
The tank that catches the dirty water from the mop. You empty this one yourself.
- 2.5 l
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
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
- Climbs thresholds up to
The highest threshold the robot takes, as the maker states it. Measure your own: the step into a bathroom or onto a balcony is often higher.
- 20 mm
Robot 3 facts

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

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.
- 4,000 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.
- 180 min
Smart features and warranty 3 facts
- Matter
Matter is the standard that lets devices from different makers work together. With it you can run the robot outside the maker’s own app.
- yes
- Voice assistants
Which voice assistants the robot works with, such as Google Assistant or Alexa.
- Alexa, Google Assistant, Apple Home
- Warranty
The warranty the maker gives in the Netherlands. Consumer law here stands apart from it and can last longer.
- 1 year
