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.

Battery capacityiPublished capacity of the robot's battery pack at the nominal battery voltage. When the maker gives a typical or headline figure and a lower rated figure, the headline figure is stored and the rated one goes in the source note, as for Dreame. A rated figure alone is stored. A count times a capacity, such as 2600 mAh x 2, is not a pack capacity. The total is stored only when the maker or a review states it.
