Bests & Worsts Reviews from Amazon

There are many small improvements to the previous generation of Eufy - the power button is now located on the side instead of the bottom, the buttons on top are actual buttons instead of surface buttons (that always got pressed while you were emptying), there is only one side brush instead of two so cord tangles seem less frequent, the double hinge design of waste/air filter is gone (air filter is accessible from main waste bin) and the unit seems a little quieter while vacuuming. The biggest new feature is of course the mapping and methodical vacuuming vs complete randomness. Overall - it does a much better job than the last generation. I swear the first generation had a human sensor and would roll immediately to whatever room I was in to constantly bump into my feet! This one attempts to vacuum in long straight overlapping lines. The app will display a "map" of your floor in real time as the vacuum travels around. This mapping requires some processing time during vacuuming though - it will pause for a second or two after hitting a wall or piece of furniture before it turns around and continues. Because of this frequent pausing, it seems to cover slightly less ground than the original - it couldn't quite finish my 1000 sq ft floor before it had to return to base. It operated for about 90 minutes and covered 940 sq ft before it ran out of charge. I did notice that there was a feature in the app that will allow it to recharge and finish the floor - that's a nice feature that I'll probably turn on. The mapping of the floor isn't remembered - so every day is a new day. It seemed to take a completely different route the second day of vacuuming. I have no idea what would happen if I picked it up and placed it in a different room - hopefully it doesn't trigger a self destruct mechanism.
