Sencor SRV 9020BK specifications

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

Robot height9.7 cm

Runtime per charge130 min

Suction power3,000 Pa

Noise60 dB

Battery capacity2,600 mAh

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.: flat or vibrating pad

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
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.: zones in the app
Room-by-room cleaning You pick one or more rooms on the map in the app, and the robot cleans only those.: yes

Robot 4 facts

Robot height How tall the robot is. It decides whether it fits under your sofa, bed or cabinet.: 9.7 cm
Robot weight What the robot weighs. It counts most if you carry it up a staircase every day.: 2.9 kg
Dust bin in the robot How much dust the robot holds before you empty it. It matters less with an auto-empty dock, which empties the bin after every run.: 350 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.: 60 dB

Battery 3 facts

Battery capacity The capacity of the battery. It hints at the runtime, but how much the robot draws counts just as much.: 2,600 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.: 130 min
Charging time How long an empty battery takes to charge fully in the dock.: 5 h
