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.

Navigation and obstacles

5 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.

Mopping
