and here.
I can sort of see it with a dehumidifier. They suck water out of the air and they stop working when their storage tank fills up. So a wifi connection would enable them to send a message that they need to be emptied so they can start working again.
The same might apply if you’re talking about a self-operating vacuum like a roomba. But I can’t see why an ordinary vacuum would benefit from a wifi connection.
“Jimmy, did you vacuum the house like I asked?”
“Of course, Mom!”
“The log shows you only ran it for 2 minutes.”
“Ummm…”
Of all the things you might think should never need Wi-Fi, a litter box surely tops the list?
But we have one. It’s nice to have the thing notify me when the collection drawer needs to be emptied, for instance.
It becomes a classic “manage by exception” experience, and the connectivity enables the exception notification capabilities.
I bought the cheaper self-operating vacuum that didn’t have Wi-Fi, among other features. 
I have one like that, too. My only regret is that when it inevitably gets stuck in another room, I cannot hear its cries for help.
A non-wi-fi vacuum cannot be reprogrammed by the cat.
Note that our toaster, oven, air fryer, roaster combo thingy is wi-fi enabled. Why? Don’t ask me, Mr. Luddite. To shut the thing off, I unplug it to my wife’s consternation. I refuse to have that app on my phone.
My coffee maker (nespresso vertuo) is wifi enabled, and I have the app. It’s nice when the thing just blinks red at you instead of making coffee, I can open the app and see what it’s complaining about.
It’s not nice when I have to re-enter the password, but forgot the password, and need to reset the whole thing because it forgot who I am, just to find out that the lever wasn’t closed all the way.
Our washer and dryer are WiFi enabled. I’ve put them on the guest network, so they can only interact with the Internet. Mrs Magill and I will go out on Saturday, leaving the boy at home who’s responsible for keeping the laundry moving. The apps will let me know when the cycles are done, so I can then bug the young man who is probably playing X-Box.
“Starting a meta-leaderboard for tracking who holds the record for ranking behind the most distinct people on an online leaderboard.”
7 million is a lot. But rankings in the thousands is common for some sports. Well, at least one! I have participated in USBC bowling tournaments that run for multiple weeks and have tens of thousands of participants in the amateur category. I have bragged that I came in 3,456 in my age/handicap group.
“It’s hard to be ranked that low in any activity.”
How about Marty McFly costume making?
Somehow this “global ranking” one is hitting close to home here on the SDMB. Especially the last panel.
I just checked …
The USGA governing body for golf issues official handicaps to recreational golfers. They now have some 3.35 million handicapped golfers. Out of ~26 million US golfers. Unclear to me whether / how they distinguish between currently active and former / deceased players.
Punchline being that if all recreational golfers got officially handicapped, being merely the 7.145millionth best golfer would put you at about the 25% percentile of skill, better than 3/4th of the other golfers out there.
See this ~8 month old article for more.
I took this comic as a commentary on how a large number like 7,145,000 is called a low ranking. Language is weird.
You’re talking to a guy who bought his vacuum cleaner at a Goodwill store. It’s self-operating in the sense that I operate it myself.
I’m not sure I follow; Marty McFly was afaik wearing ordinary street clothes. How would you make a “costume” of that?
Not exactly:
You can’t fool me -that’s a BTTF3 costume - totally different head (totally)
You gotta count from one end or the other.
Should we call a fat cat a “1 percenter”, or a “99 percenter”? Their wealth is >= 99% of the populace, and <= just 1% of them.
Whatever you do, don’t turn up the air conditioner to make the room cooler. 
I’ve mentioned before that my refrigerator has an adjustable dial from 1 to 9. It’s helpfully marked “9 = max, 1 = min”. Does that mean that 1 is the minimum temperature, or that 9 is the maximum amount of cooling?
