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.

We got a Roomba 405 from Harvey Norman for about $700. Comes with vac and mop. Pretty happy with it so far!

I recommend the 405. The 105 water tank is too small to mop more than 1 big room at a time and is not practical to refill. You will then need to remove the mopping pad and wash it then dry it before putting it back on. The 405 on the other hand has a large water tank and large dirty water tank and it washes the pads for you, then dries them after it mops. The spinning mop pads also do a much better job mopping the floor.
