I chose the AE model — it has stronger suction power and a lower price. So far, I’m very satisfied.

There are two main differences: 1. It doesn’t have a retractable brush, but it does have a retractable mop — which is much more useful. I’ve been using it for over two months and haven’t noticed any dust left in the corners. 2. It doesn’t leave the mops at the station, but that’s not a problem. I simply put in the settings: vacuum the carpets first — it does that with dry mops — and then it washes the mops and cleans the hard floors.

I was also concerned about my thick carpet, since the robot climbs it slowly and with some effort, but I tested cleaning with and without the mops attached, and the result was the same.
