Tecbot S3 Pro 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.
- 4,000 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
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.
- flat or vibrating pad

How much clean water the robot carries. It sets how long it mops before a refill, which a dock does by itself.
- 240 ml
Navigation and obstacles 2 facts

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.

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.

Robot 2 facts
- Robot height
How tall the robot is. It decides whether it fits under your sofa, bed or cabinet.
- 4 in (10.2 cm)

How much dust the robot holds before you empty it. It matters less with a self-emptying dock, which empties the bin after every run.
- 300 ml
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.
- 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.
- 150 min
Smart features and warranty 1 fact
- Voice assistants
Which voice assistants the robot works with, such as Google Assistant or Alexa.
