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

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 turret5Retailer pageamazon.com/dp/B0F3BSWC9PRead 15 October 2026Dreame's comparison chart on the Amazon US page lists Navigation: Fixed LDS, a fixed laser distance sensor turret.

Mopping

4 of 8 differ

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.

Static pad1Maker product pagedreametech.com/products/d20-pro-plus-robot-vacuumRead 15 October 2026Spec table: Detachable Mop Pad. The store sells a Flat Mop Pad that wipes the floor as the robot drives, so it is a static pad

Not available

Mop downforce (claimed)iThe maker's claim for the force that presses the mop onto the floor. A claim in kilograms is converted at 1 kgf = 9.80665 N and rounded to one decimal, so 1 kg is 9.8 N. When the maker also gives a figure in N, that figure is stored. When the maker gives a range, such as 9-11 N, the top of the range is stored.
