These are all problems that can be solved with basic engineering solutions.
The only lesson to be learned here is that there is a ton of room for improvement with the current set of robot household helpers.
Finally, I have an older model, but the new Roomba 980 includes a camera so they are working on new navigation tech, albeit slowly and at crazy high prices.
Unless something thinks there's a huge technological gap to cross?
Other than that it works quite well.
