Sencor SRV 9020BK specifications
The numbers that matter first, then every fact by group. As published by the maker or the store we read it from.
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.
- 3,000 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 and boosts suction
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.

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 recognizes more.
- LiDAR turret
- No-go zones
How you keep the robot out of a place: a zone you draw in the app, a virtual wall or a magnetic strip on the floor.
