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.
Xiaomi Robot Vacuum S20 specifications
The numbers that matter first, then every fact by group. As published by the maker or the shop we read it from.

Dimensionsrobot and dock
From the published dimensions. The robot passes under furniture with 10 cm of clearance or more.
Suction and brushes 1 fact

- 5,000 Pa
Mopping 2 facts

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.

How much clean water the robot carries. It sets how long it mops before a refill, which a dock does by itself.
- 270 ml
