Assuming you live in a crazy big house (1000 m2), it cleaned your house 74000 times. Given S5 was released 8 years ago, even approximating it to 10, that's 20 times a day. I can imagine it taking about an hour to do one clean run. Jesus, did it ever stop cleaning

They probably meant 74000m², not 74km².

no way it covers 1000m2 in an hour. It is ~35cm in diameter, so it has to travel around 3km. That would mean it'd require around 1m/s, which is 3times its rated speed... Then of course, it'd have time to charge. Even with 1C it's still 1 hour between cleaning sessions. We assume regular battery changes every couple of weeks too

I would be a bit more charitable to OP here because it's not their fault, it's the Roborock app's fault. They convey in their UI the information of total surface cleaned in xxKm2 with the K bolded. But the km doesn't mean square kilometer it means thousands of square meters apparently. It's easy to just take the information at face value as OP probably did here. He went in app, saw the number and the very weird unit for the info and just posted it.
