## Frequently asked questions about the Roborock Saros 20 Sonic

**Does the Roborock Saros 20 Sonic empty its own dust bin?**

Yes. The station empties the robot’s dust bin after every run. The 2.7 l dust bag in the station lasts up to 65 days, the maker says.

**Does the Roborock Saros 20 Sonic wash and dry its own mop?**

Yes. The station washes the mop itself, with water at 212 °F (100 °C). It then dries the mop with warm air.

**Does the Roborock Saros 20 Sonic work with Alexa, Google Home or Siri?**

It works with Alexa, Google Assistant and Siri. It also supports Matter, so it fits into another brand’s app. Home Assistant has an official integration for this model.

**How high a threshold can the Roborock Saros 20 Sonic climb?**

Thresholds up to 1.8 in (45 mm), the maker says. With its climbing system it also takes two steps close together, up to 3.5 in (88 mm) in all. Measure your own thresholds: the ones to a bathroom or balcony are often higher.

**Does the Roborock Saros 20 Sonic fit under low furniture?**

The robot is 3.1 in (8 cm) tall, so it fits under furniture with at least 3.2 in of clearance. Its lidar turret retracts where space is tight.

**Is the Roborock Saros 20 Sonic suitable for pet hair?**

Yes, the maker says. The brush guides hair to the side instead of winding it around the roller.
