Just got it yesterday and tried it. A few differences to the 30C caught my eye straight away: Only one side brush instead of two (I don't know how I feel about that as I find the side brushes are actually great for picking things up off the edge) The cleaning robot says - Much more systematic cleaning is possible in a straight line - mapping Overall this vacuum is great, sucks very well, seems to clean well and systematically and hardly misses a spot. I had a spot where it got stuck between a wall on one side and two objects on the other two sides. You can schedule cleaning and also use Alexa MAPPING: - This is a handy feature but it seems a bit useless. That means you can't really use mapping to create forbidden/prohibited zones. Not entirely sure what this is for, other than being interesting to look at after a cleansing session. I will update this review as I use it more often.
