Suction and brushes

7 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.

25,000Pa1Maker product pagedreametech.com/products/l40-ultra-gen2-robot-vacuumRead 15 October 202625,000 Pa Vormax suction from a 6th-generation TurboForce motor. Footnote: based on in-house lab data

Suction power (claimed)iThe maker's suction power claim in air watts. Few robot makers publish it. Pascals are a different measure and go in Max suction.

Navigation and obstacles

2 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.
