How to Choose a Robot Vacuum: Suction, LiDAR, and Mopping
Robot vacuums split on four things: suction (Pa), navigation sensor, mopping style, and dock. Most homes are fine at 4,000Pa with LDS LiDAR; caked grime needs 2kg-plus rotating pressure.

Robot vacuums split on four things: suction (Pa), navigation sensor, mopping style, and dock. Most homes are fine at 4,000Pa with LDS LiDAR; caked grime needs 2kg-plus rotating pressure.

Pa, W, AW, CFM — suction figures use different units per brand, measured under different conditions, making direct comparison nearly useless. Here is how to read the real performance hiding behind those numbers: filter type, obstacle detection, and mop separation.
