That may explain it. I have a Qrevo S, which is from 2024, while yours is from 2022. The only thing that it ever gets stuck at is one spot where, from under the couch, it can see out the ground-level window, and get stuck between the couch and window ledge (not actually stuck, just confused), because the LiDAR sees out the window. And I fixed that just by setting a small exclusion zone there. It never "gets lost" - maybe your house has some vast open spaces that it can't handle? But the LiDAR seems to see pretty far. The only other issues I've had are things like where I'll have a loose cord on the floor or some large piece of debris or whatnot, and even then, it's usually good at not getting stock on them. I'm also impressed with how well it deals with doors vs. a Roomba - my Roomba used to always get itself locked in rooms by accidentally closing doors after it entered, while the Roborock really tries to avoid ever touching them.

The Qrevo S has actually rotating mops, and they do a superb job with the floor. Spotless. My robot has the hardest mopping job in the world, too - it has to clean under my parrot's cage, and he poops off the edge onto a plastic mat under it ;)

I've never had to contact support - hopefully I don't need to :)

There are too many ways known to attack SHA-1. Why can't they at the least use SHA-2? Even better, go straight to SHA-3.

although map editing sucks and it often gets lost and can't properly reset its position. It needs to be rescued pretty often which is a major fail.

That's very distinctly not my experience. What version do you have?

A real vacuum cleaner just about maxes out a standard residential 120v 15a circuit, as anyone who remembers the incandescent bulb era can attest to. A circuit with a few lamps shared with a vacuum cleaner could easily end with you flipping a breaker or replacing a blown fuse.

When you look at the absolutely tiny lithium ion pack these robo-vacs come with, ...

Sitting on my kitchen table right now is a drone pack. It's 57,5Wh, smaller the batteries of most modern Roombas. It's 50C - thus it can output up to 2,9kW. And there's even higher packs available than that. Lithium ion cells can handle some truly high power outputs. It's *energy*, not *power*, that is their limitation. Run a pack at 50C and it'll be empty in a bit over a minute. That said, on hard floor surfaces there is absolutely no reason why you should be drawing more than 300-400W or so, and you can get by with well less than that. High powers are for like shag carpeting and the like. Also, the head matters more than the power (though of course contribute) - for a hard floor, for example, a fluffy roller head is ideal.

Pet hair has never been an issue for me with robots. My long hair always is. It's way longer than any pet's.

Yeah, my Roborock has rotating mops, and I can say with 100% certainty, I haven't lived in a cleaner house since I moved out of my OCD mother's place as a teen. You could eat off that floor.

Facts. I used to have a Roomba for years, but as I live in Europe, it was getting increasingly hard to deal with modern features (like the self-emptying base which needs 120V power). I reluctantly switched to a Roborock when my power converter died, and just, wow, they're light years ahead of iRobot. I think iRobot has been coasting on its name for a while now.

If you think being a CS RCG is bad, try being a 55 year old coder who spent the last 30 years honing the craft, only to be laid off into a market where those skills are just no longer needed at all.

Maybe originally, but now the demand for gasoline far outstrips the amount naturally found in crude oil. That's why they invented cracking.

If one day there ever were an excess of light components in oil, they could simply transform it into higher-weight molecules. Along those lines, one of the biggest uses for natural gas is for building polymer chains.

Yeah, the charging situation is interesting.

If you charge at home, so much cheaper than gas.

If you can't charge at home, so much more expensive than gas.

Well, sure, but you can say the same thing of so much in automotive tech...

When all those gaskets need to be replaced, when the transmission grinds itself, when the coolant system leaks, when the turbo goes, if the timing belt goes, every few months when you change the oil, etc etc.

Sure, it's a item worthy of being wary of and a good opportunity to improve, but it's not like ICE engines are nice and immune from expensive costs down the line.

PBS is primarily (85%) privately funded. It will continue to produce shows like Masterpiece, Nova, Frontline, and Sesame Street and people in places like Boston or Philadelphia will continue to benefit from them.

What public funding does is give viewers in poorer, more rural areas access to the same information that wealthy cities enjoy. It pays for access for people who don't have it.

By opting out, Arkansas public broadcasting saves 2.5 million dollars in dues, sure. But it loses access to about $300 million dollars in privately funded programming annually.

Well, I'll have to admit, I didn't have "learning that someone on Slashdot believes that the Cold War was a myth" on my bingo card for today.

Seriously, the idea that we know all the practically important physics there is is the kind of thing only somebody who's never done science or engineering would believe.

You seem to be confusing "wanting to get rid of communists" with "wanting their countries to be poor and dangerous".
