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 :)

Perhaps you need to submit some stories that you thing would be more suitable. But I would only work for one of the named companies if I were desperate.

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?

It's not clear that when you include all externalities fission power is the cheapest way to power the grid. But there are places where it probably is the cheapest way to power something. (Or if not cheapest, has other overriding benefits.)

OTOH, including all externalities is tricky. I'm always dubious when I read a claim that it's been done.

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.

The FORTRAN IV that I wrote in the early 1960's would still compile and run today. The FORTRAN II that people were writing a few years earlier wouldn't even compile and run by the time I started programming.

It may be temporary (I doubt it), but it's not "very temporary" as the same thing has been reported for months with pretty steadily increasing urgency.

OTOH, the AIs clearly aren't good enough to replace programmers, or probably even coders. So what's currently happening is probably jobs being redesigned to use an AI where it makes sense. Expect LOTS of failures in this redesign, but it will be the successes that shape the future...unless the AIs get a LOT better. (Currently they don't understand the problem they're trying to answer.)

Molten salt may well be a viable answer to many problems. But, yeah, it needs development...and it's not clear that it would be cheaper for grid based power.

You're assuming that the current skills will serve you later. This MAY be true, but is by no means guaranteed. The interfaces of current AIs are definitely quite immature, and can be expected to change a lot. Probably also their competency.

Plausible, if it's good enough. The real problem here is lots of shitty code being submitted. So much that they need quick ways to get rid of most of it.

As for "explain the code", that's trickier. I remember struggling to explain why I did something a particular way a few months later. When I figured it out again, it was the right approach, but it wasn't obvious why.

Well, prompts left in the comments isn't really a flaw, just an indication.

OTOH, what they're saying is "We're being swamped, so we're going to have to triage the code.", which is unfortunate, but reasonable.

Depends on the language. Where I worked you needed to work in SPAN (a language from SBC), but when they tried to shift us over to MADAM it basically didn't work. (I shifted over, but to PL/1.)
