Great read!

15 years ago, I had one of the first robot lawnmovers (Husqvarna) and did exactly the same thing: Watched it for hours, observing how it worked.

Back then, it seems it was programmed with instructions:

- Go! If you hit an edge, rotate in a random direction and ... Go! - If crossing the base-wire (a buried wire leading to the base station) while battery level < 40%, follow it and charge.

I'm still in the cynic camp for a few reasons. 1. My flat is small. I can do a decent vac in about 15 minutes. 30 minutes if I do under the bed. 2. When I do the "big vac", I have to move 6 dining room chairs. Then shift the table a few inches. Zoom. Shift if back. Same goes for some other legged furniture. 3. I also do the windowsills. No bot can do this. 4. Don't you end up with little arched dust patterns in every corner of every room? How does a round vacuum do this? Seriously! This is the deal-breaker for me unless they have some little robot-wars-style dust-brush that shoots out to get into the 90 degree angles.

All that said, I really really want one!

Working on robotic lawn mowers - I still had the same feeling watching them do their thing. You can get pretty far with random turns with some edge following.

One thing that can help a lot is gps (or other absolute position). This can definitely help make sure your robot can make roughly the correct turn to get in those nooks.

They have a brush.

I've found that while it doesn't do a lot of what a human would, it can do it daily. In my case the time savings made it pay for itself in half a year.

A good way to explore the algorithms of the robot is to set it out to run in the night. At the entrance of the room, set a high obstruction. Set up a tripod. Take long exposure photos every minute or so. Then turn on the lights/wait till day time. Take another photo. Overlay the photos in an editor program. Spot the missing areas.

EDIT: here are some examples by other people: https://spectrum.ieee.org/automaton/robotics/home-robots/lon...

And here are some resources if you have a Xiaomi robot vacuum cleaner (also sold as RoboRock) https://github.com/dgiese/dustcloud

So we have a roomba, and hands down that's one of my favourite devices that we own - we just pretty much never have to hoover downstairs, it starts automatically at 9am every morning, we come home to a clean house, it's amazing. When we need to clean the upstairs bedrooms I can just leave it there, press start, and it does its thing and we can go and have dinner in the meantime. Yes, you still have to hoover manually from time to time. No, it doesn't do corners very well. But the fact that it can automatically clean at least one level of your house every single day is just incredible.

1; Same here. I still prefer to do other things with my time. Of course this is a luxury, but an affordable one.

4; There is a side brush (maybe even two) on most models. For the exact reason you mention.
