The Eufy 11 s works very well. I usually just put it on auto setting and away it goes. Just gotta make sure little things like LEGO pieces are picked up before letting it go. It’s a hell of a lot quieter than I expected. It’s fantastic. For the price I expect it to go to each room and suck up on a random zig zag path. One day when I upgrade I’ll go for a more precise movement through each room. But I love it. It’s great.
