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.
