Lidar is the gold standard of robot vacuum navigation, but it's not perfect

Any robot vacuum owner can understand my frustration over having to occasionally save my bot from gobbling up a pair of socks, being tripped up by pesky wires, or even getting stuck under furniture.

You could say that no two cleanings are ever alike. That's unless you're pretty good at precleaning.
