Technical approach

As reported

Vacuuming

High-powered suction

20,000–22,000 Pa with dual anti-tangle rollers. Ultrasonic mopping lifts stains without drenching floors. Mop lifts 2.2 cm for carpets.

Robotic arm

Five-axis OmniGrip

Unfolds from top, extends 30+ cm with LED lights and weight sensors. Picks up socks and tissues under 300g.

Navigation

Autonomous mapping and path planning

Roborock robots map rooms, avoid obstacles and plan efficient routes. The Saros Z70 vacuums first, then uses the arm to remove obstacles in a second pass.
