Overview
Roborock built the Saros robot to clear high thresholds with a lifting chassis and to slip under low furniture, while depth sensors and a color camera map rooms and steer around clutter. Its dock washes mops in hot water and dries them with hot air.
Getting over tall door sills and under low beds without help is the reason to buy. A dual anti-tangle system cuts brush cleaning, but the listing gives no runtime or bin size.
Who it's for
Multi room homes with door sills, rugs and pets will use the lifting chassis and anti-tangle brushes. Small apartments without thresholds may not need its climbing ability.
Pros and cons
- Lifting chassis crosses tall sills
- Recognizes many obstacles
- Very slim for low furniture
- Hot water mop washing
- Runtime not listed
- Bin size not given
- Camera use may concern some
Performance notes
Threshold crossing depends on the chassis raising the body without cutting suction. Mapping accuracy comes from time of flight depth sensors, and the camera identifies objects to route around. Hot water washing and hot air drying keep mop pads clean between runs.
