Granted, I haven't had an opportunity to tear apart newer models, but I'd be really surprised if the more advanced sensors would be much more prone error after a bit of dust gets stuck to them.
However I rigged up a shell routine that grabs the lp printer file on my mac in a way that I can then use spotlight (osx) [1] to instantly find and bring up the pdf so I can also find what I need that way. (And I even have a "fake" printer setup in case I don't want to have an actual paper printout for some reason.
[1] So the shell routine looks at the file and determines if it's text file, a .ps (postscript) file, or already .pdf and appends the right suffix so it can be open by clicking and spotlight can search it.
The camera and navigation are an expected improvement, but other than that doesn't look better than my old Roomba clone, it is even missing some features.
I'm kind of surprised to read people who don't look after their vacuum cleaner. Whatever brand it is: change the bags (if it uses them); change the filters; occasionally give it a clean.
