Suction and brushes

10 of 13 differ

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

8 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.

Lidar turret1Maker product pagedreametech.com/products/d30-ultra-robot-vacuumRead 15 October 2026Page: dynamic laser navigation with smart 3DAdapt obstacle avoidance. The robot is 97 mm high, so the laser sensor is fixed on top. Vacuum Wars calls it spinning lidar and the manual lists an LDS cover and a laser distance sensor

Built-in lidar or ToF sensor1Maker product pageankernordics.com/robot-vacuum-s2Read 14 October 2026Page says CleanMind AI is powered by a 3D ToF sensor. No turret. Stored as built-in ToF sensor. The manual calls it a 3D dTOF sensor

AI object recognitioniA camera and software identify objects such as cables, socks and pet waste and steer around them.

Mopping

Mop typeiNone means the robot only vacuums. Spinning pads are round pads that rotate. A roller is a turning cylinder. A track is a belt-shaped mop that rolls over the floor. A vibrating pad moves back and forth. A static pad is dragged.
