If I had the extra cash, I’d buy a Eufy 11S....it seems like a very good buy at about $220, and it did quite well in Consumer Reports tests. I would never expect it to replace a regular vacuum cleaner, but to have it pick up surface litter every day while I am away at work makes a lot of sense. It would be a really convenient way of getting rid of lots of surface litter without me lifting a finger, really.
