Thresholds are no obstacle

Sliding-door rails, bathroom thresholds and uneven transitions between rooms it climbs by lifting its chassis – according to Roborock up to 4.5 + 4.3 cm in two steps. It also drives out of U-shaped furniture legs where other robots get stuck.

A dock that washes while the robot vacuums

The dock washes the mop separately with up to 100 °C water, so the robot can keep vacuuming meanwhile. Afterwards the mop and dust bag are dried with 55 °C warm air, and the dock doses cleaning solution and refills hot water.

Out of the dock and under the furniture

The retractable LiDAR sensor lowers when the robot drives under furniture, so it reaches spaces down to 7.95 cm, and rises again for a 360° map in open areas.

Product FAQ

How does it differ from Saros 20?

Saros 20 Sonic mops with a vibrating, extendable mop and has a retractable LiDAR. Saros 20 has two rotating mops and a solid-state LiDAR. Both have 36,000 Pa suction and climb two-step thresholds according to Roborock.

How long does the battery last?

According to Roborock up to 180 minutes when vacuuming and mopping on balanced suction. It charges from 15 to 100 % in about 2.5 hours.

How loud is it?

According to Roborock no more than 55 dB when only mopping and about 63 dB when vacuuming and mopping on balanced suction.

Will rugs get wet?

No. The robot detects rugs and lifts the mop, and in vacuum-only mode the mop stays in the dock.

Description

Saros 20 Sonic mops with a vibrating mop instead of rotating mops. According to Roborock it vibrates 4,000 times a minute with 14 N of pressure, and it can extend out to the edges to reach along walls and into corners.

Suction is 36,000 Pa according to Roborock, and the brushes are built so hair doesn't tangle. The chassis lifts over two-step thresholds of up to 4.5 + 4.3 cm, and on rugs the mop lifts so the rug stays dry.

The robot gets under furniture down to 7.95 cm thanks to a retractable LiDAR sensor. Structured light, an RGB camera and a side laser help it see narrow obstacles along walls and cables on the floor.

The dock washes the mop with up to 100 °C water while the robot vacuums, dries the mop and dust bag with 55 °C warm air, doses cleaning solution and refills hot water. According to Roborock the battery lasts up to 180 minutes and charges from 15 to 100 % in about 2.5 hours.
