Yeedi S20 Infinity specifications
The numbers that matter first, then every fact by group. As published by the maker or the store we read it from.
Yeedi · on the market since September 2025
Consumables: no dust bags to buy, the station collects the dust in a bin.
Dimensionsrobot and dock
From the published dimensions. The dock needs a spot 15 in wide and 19.4 in deep.
Suction and brushes 4 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.
- 19,500 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 baseboard, so the dust there is swept in too.
- yes
- Suitable for pet hair
Whether the robot copes with pet hair: a brush that hair does not wind around and a dock that empties the bin for you. Where the maker does not say so itself, we read it from those two.
- yes
Mopping 4 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.
- roller mop
- Mop lift on carpet
How far the robot lifts the mop when it drives onto a carpet. From about 0.4 in (10 mm) a medium pile stays dry.
- 0.4 in (10 mm)
- Mop extends to the edges
The pad slides out along a wall or a baseboard, so the last few inches are mopped as well.
- yes
- Automatic mop detach
The robot leaves the mop at the dock before it vacuums a carpet, so the carpet never gets wet.
- no
Dock 8 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.
- yes
- Washes the mop
The dock washes the mop for you, so you do not rinse it by hand.
- yes
- Wash temperature
How hot the dock washes the mop. Above 140 °F (60 °C) grease comes off, which is what keeps a mop from smelling.
- 167 °F (75 °C)
- 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
- Dock size (w × d × h)
The width, depth and height of the dock. Measure the spot you have in mind, and leave room for the lid and for the robot driving in.
- 15 × 19.4 × 18.3 in (38.1 × 49.3 × 46.5 cm)
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.
- built-in LiDAR, no turret
- 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.
- 0.9 in (23 mm)
- Climbing system for high thresholds
An extending leg or wheel that carries the robot over a high threshold. Without one it usually stops at about 0.8 in (2 cm).
- yes
Robot 2 facts
- Robot height
How tall the robot is. It decides whether it fits under your sofa, bed or cabinet.
- 3.9 in (9.9 cm)
- Dust bin in the robot
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.
- 220 ml
Battery 1 fact
- 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.
- 254 min
