Lidar doesn't work for some things- my Roborock S7 has trouble if there's a USB cable on the ground or a lamp's power cord isn't tucked all the way up against the wall. Supposedly the camera models are better at avoiding certain obstacles, which is good if you have a pet or housemate who sometimes poops inside and you don't want that getting mopped all over the floor.

That's a compelling use case for me but considering how many of these vacuums have had privacy issues, I stuck with Lidar (people cast aspersions on the Chinese companies but US manufacturers have track records that don't inspire confidence either - just ask the Roomba employees who got their naked pics leaked online)
