The strongest fit for pet-heavy homes with mixed flooring, low furniture, and transitions that stop ordinary robot vacuums.WATCH IT CLEAN THE ROOM
WHAT THE HARDWARE CHANGES
From specification
to living space.
Clears the transitions that usually divide a map
AdaptiLift Chassis 3.0 can raise the robot as it approaches uneven flooring. Roborock claims clearance of up to 3.46 inches across a two-stage threshold and cleaning on carpet up to 1.18 inches deep, reducing the need to split a home into separate runs.
Maps in three dimensions, then plans around clutter
StarSight Autonomous System 2.0 combines 3D time-of-flight sensing with an RGB camera. The system is designed to classify more than 300 obstacle types, building a route around cords, pet items, and temporary clutter instead of waiting for a collision.
Reaches beneath furniture without a raised lidar tower
At a claimed 3.13 inches tall, the Saros 20 is designed for the dust line beneath sofas and beds. The supplied listing also uses 3.14 inches in its title; the smaller 3.13-inch figure is the manufacturer’s stated minimum clearance.
Pairs high suction with less brush maintenance
The 36,000 Pa digital motor targets hair embedded in carpet and debris sitting in floor gaps. A dual anti-tangle system manages hair around the main and side brushes, while FlexiArm hardware extends toward edges and corners.
Moves the mess into a mostly hands-off dock
RockDock washes the mop with water heated to 212°F, dries it with 131°F air, cleans its own tray, and stores collected dust for up to 65 days. That turns daily cleaning into a refill-and-empty routine rather than a brush-and-pad routine.
