I know that the OP has already made this decision, but I might as well throw in my experience for other readers.
My Deebot M80 Pro (nicknamed "Helen Keller") was a black Friday impulse buy to assist with the copious cat hair and litter than can infest a studio apartment. At its best, the Deebot is great for sucking up pet detritus, but it rarely brings its A game. Unless you thoroughly vacuum-proof your apartment, it WILL get stuck. I'm not just talking about any kind of wire, from power strip cords to phone chargers. Ms. Keller will relentlessly hump any small elevation (like the 1.5" base of my cat tower) until the battery runs dry, never realizing that the 985th try is probably not going to work better than the 743rd try. I'll even come home to it drained on the 60-degree, 2-inch-wide legs of my dining table! If by a miracle the Deebot completes its cleaning cycle you're faced with another 50/50 chance of it finding the charging dock (in a 500 sqft Manhattan studio, not a maze or palace).
Overall I would say that this product saves me work (especially if I'm home to untangle and extricate it during its cycle), but its' not the sort of thing you can rely on to tidy up on a timer before friends visit.
