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)
"good if you have a pet or housemate who sometimes poops inside"
I have a pet (cat) that unfortunately poops just outside her box most of the time, despite a lot of different ideas and approaches with the help of our vet. She's old and has lower back pain issues. It ends up on a litter mat or the wooden floor, so it's not that hard to clean up.
If I had a housemate that pooped inside not in the toilet, they would need to be even less able to manage their shit, so to speak, and more loved than our cat, or they would be out of here very fast.
