Pros & cons
Roborock Saros 20
- ✓AdaptiLift 3.0 chassis climbs double-layer thresholds up to 3.46 inches - unmatched for split-level homes
- ✓36,000Pa suction and a 6,400mAh battery cover large homes with up to 200 minutes of runtime
- ✓Embedded 3D ToF StarSight 2.0 LiDAR keeps the body at 3.1 inches to slide under low furniture
- ✓Dual spinning mops apply adaptive pressure up to 13N and get washed in 212°F hot water at the dock
- ✓Recognizes around 300 obstacle types with VertiBeam lateral avoidance for cables and clutter
- ✗At $1,599.99 it costs flagship money without the Sonic's vibrating deep-scrub mop
- ✗Small 69ml onboard water tank means constant dock returns on big mopping jobs
- ✗259ml dustbin is modest for a vacuum aimed at large, complex homes
- ✗Tall multifunction dock demands a lot of floor and vertical clearance
