I don't know about the best, but I got ourselves a Roomba Plus 405 (G181) and I'm pretty satisfied with the results - despite the mediocre reviews. We have a large kitchen area with few runners and carpet and the robot does a pretty good job mopping the lvp and keeping the area clean. I run it once every 2-3 days. It cannot really reach the inside corners very well and collect the crumbs or debris there. But everything else is really good.

I have the Roomba 405 with the lidar and it’s the best robo vacuum I’ve ever owned. The mopping feature is a huge time saver- I have two dogs with muddy feet any day it rains and it used to mean dragging out the steam mop but now just click a button on the iPhone and done. The vacuum is also great. The auto-empty dock is amazing and even though the dock uses disposable bags you can just empty the disposable bag and reuse it. Just a great product all around. They’re pretty cheap now too.

My roomba pulls the spinning mop pads up when it’s not mopping. Works great.

So I have a Roomba model 405, vac and mop 2 in 1. Documentation says it has LiDar. Did they lie or did I misunderstand? I am confused.

Love our J9. “Upgraded” to a 405 and it is horrible for pet hair.

I equate robot vacs to hand sanitizer. They do the job, but at the end of the day, soap and water make your hands feel the cleanest. I have both an ecovac deebot and a roomba 405. Honestly, the cheaper deebot worked more consistently than the Roomba. Their app is dodgy as heck. If you have pets with fur, I've found the old school janitor brooms to be the most efficient and effective on floors. Too much fur tends to clog up Roomba vacs. Go cheap to dip your toes in the robot waters.
