Our verdict
The Saros 20 is one of the most capable robot vacuums sold today. Expert Reviews' only real complaint was cost, and it suggested cheaper rivals offer around 90% of the ability for half the price. Buy it on discount if you want the best.
What we like
- Expert Reviews called its suction the highest it had tested and its object avoidance outstanding
- Climbs double thresholds up to 3.46 in, according to Roborock
- Slim body fits under low sofas because there is no LiDAR turret
- Works with Alexa, Google Home and Matter
What to know
- Expensive at full price
- Carpet deep-clean mode has to be switched on manually in the app
