Test and spec page for the Eufy Omni S2, read Oct 22, 2026. Lab results: carpet deep clean 87, flattened pet hair pickup 88.5, zero wraps in the 7-inch hair tangle test. Specs: one roller mop that lifts 28 mm on carpet and stays on the robot; 42 mm threshold climbing.
Read the sourceObstacle-avoidance ranking (last updated Oct 21, 2026) from a standardized 24-object course that includes simulated pet waste, plus a cluttered torture test. The Eufy Omni S2 avoided all 24 objects; the Mova V70 Ultra Complete avoided 23. Notes that top-mounted LiDAR can miss low objects, so front cameras and sensors do the avoiding.
Read the sourceReview of the Roborock Saros 20 (MSRP €1,499): its AdaptiLift Chassis 3.0 climbs steps up to 8.8 cm, but only as two steps of 4.5 and 4.3 cm, more than double the Saros 10R's 4 cm. Reliable obstacle detection, under 8 cm tall, average battery life.
Read the sourceReview of the Saros 20 Sonic (last updated Aug 28, 2026): it cleared a 57 mm single threshold, above Roborock's 45 mm rating and tied with the standard Saros 20 for the best result Vacuum Wars has recorded. Strong vacuuming; mopping below expectations for the price.
