Vacuum Wars

Roborock Saros 20.
Crosses 3.5-inch thresholds that stop every competitor. The StarSight 2.0 sensor array maps 21,600 points and dodges 300+ obstacle types.
The Verdict.
9.6/ 10
Gavler Meta-Score
“If you have a home with mixed flooring, area rugs, or door thresholds, the Saros 20 is the only robot that won't get stuck constantly. The threshold-crossing capability alone justifies the price for many households. Navigation is best-in-class, suction is excellent, and the hot-water dock keeps it hygienic. It's expensive, but it's the first robot that truly works in imperfect homes.”
