Max suction (claimed)iThe maker's highest suction pressure claim in pascals. Each maker measures it in its own lab, so figures from different brands are not directly comparable. A claim such as "175x more suction" is not converted. A maker can claim another figure in another market, such as Roborock in the US, so it is per variant.

Navigation and obstacles

4 of 8 differ

NavigationiHow the robot maps the home. A turret is a raised laser sensor on top. A retractable turret sinks into the body to pass under furniture. Built-in lidar sits inside the body with no turret. A solid-state 3D ToF sensor without a turret counts as built-in lidar. Camera means visual mapping without lidar. Gyroscope only means the robot has no mapping sensor and cleans in rows with a gyroscope. Random bounce means the robot has no mapping sensor and no gyroscope and turns when it bumps into something.

Random bounce6Measurementvacuumwars.com/compare/robot-vacuums/eufy_11s_maxRead 15 October 2026Compare data record: Navigation Type Random. Stored as random bounce

Lidar turret4Reviewvacuumwars.com/shark-ai-self-empty-xl-review-av2501aeRead 14 October 2026Review says it uses a top-mounted LiDAR system. Vacuum Wars says AV2501AE, AV2511AE and RV2502AE are the same robot, with different bins, parts and cosmetics

AI object recognitioniA camera and software identify objects such as cables, socks and pet waste and steer around them. A structured light sensor without a camera counts when the maker says it identifies object types, as Narwal does. A bump sensor or infrared sensor alone does not qualify. False only when the maker or a spec table says the feature is absent. Silence is a missing value.
