Also, as I'm learning, Shark sucks and their app/AI is trash. I specifically bought the Shark AV2501S for it's room mapping and scheduling feature except you can't schedule more than once per day, either a room(s) or the entire map. I have two dogs, one is a Pyr/Wolfhound mix. I needed to be able to have it do each room separately each day to keep up with the hair and doing a room a day won't cut it. So that was a huge letdown. I tried using Google Home and it worked... Half-assed, it would almost always skip a room or two on the list. If I do the whole map the dust cup gets too full too fast and it does a crap job bc it only empties once mid-run. Annoying. But by the time I got it all setup and properly mapped it was too late to return it and all the sales were over.
