Price history
Roborock Saros 20 Flow specifications
The numbers that matter first, then every fact by group. As published by the maker or the store we read it from.
Consumables: a dust bag in the station, which lasts up to 65 days.
Dimensionsrobot and dock
From the published dimensions. The dock needs a spot 15 in wide and 17.9 in deep.
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.
- 36,000 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 3 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.
- 0.6 in (15 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
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
- Dust bag lasts
How long the maker says a dust bag lasts with daily use. With pets or a lot of carpet it is shorter.
- up to 65 days
- 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.
- 212 °F (100 °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 × 17.9 × 17.8 in (38.1 × 45.4 × 45.1 cm)
Navigation and obstacles 4 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.
- retractable LiDAR
- Obstacle avoidance
How the robot sees loose things on the floor, such as cables, socks or a pet accident. A camera with depth sensing sees more than a bumper that reacts on contact.
- AI camera
- 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.
- 1.8 in (45 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.
- 3.5 in (9 cm)
- Robot weight
What the robot weighs. It counts most if you carry it up a staircase every day.
- 11.5 lb (5.2 kg)
Battery 1 fact
- Battery capacity
The capacity of the battery. It hints at the runtime, but how much the robot draws counts just as much.
- 6,400 mAh
Smart features and warranty 2 facts
- Matter
Matter is the standard that lets devices from different makers work together. With it you can run the robot outside the maker’s own app.
- yes
- Voice assistants
Which voice assistants the robot works with, such as Google Assistant or Alexa.
- Alexa, Siri, Google Home
