Ok, Have XV11 as shown in pic in another thread. The white marks on front bumper are from a door stop mounted on floor in my condo and the other white marks are from another bump it does every run. Had it so long, Over two years I forget if it is XV11 or XV12.
I did the firmware upgrade to 3.1 this am. Neato (Bubba) runs at 9am daily. I had to leave at 9:30 am but watched it's run till 9:30am. Bubba worked flawlessly with the 3.1 upgrade. It did exactly what I wanted to have added. Better corner cleaning. I do have left and right corner turns throughout my condo.
When doing it's run around the perimeter, It hugs the wall more closely and when coming to a corner runs slower. It then lightly bumps the forward wall, and then backs up turning slightly to the right
(front goes right against the wall on a left turn),
then makes the turn to the left and continues it's perimeter run. This now does not leave the small section un cleaned as did before.
When it enters a right turn, it slows, quietly bumps the wall, then backs up doing the slight turn while backing up which cleans the area that would normally be missed on the old turn before 3.1.
It does take the same route for the whole house as it did before which is fine. Except for the better corner cleaning, Exactly what I wanted with this upgrade, Right now I feel that it is at the point where I really don't want for anything specific from another upgrade.
With the brush and filter upgrade, I see the suction is much better and sucks debris from farther the side where it did not before. Do I want a side brush? Shure. That can only help and not hurt, right? Although I will not mod to get this feature.
What is different with 3.1 for me....
It rides the wall closer on the initial perimeter run.
When it comes a few feet from a corner, it slows down which makes the clean time a little longer but cleans corners more thoroughly as i want now. Not an issue. I welcome this.
Everything else is the same.
As I say, I am a lucky owner that has had my Neato for over two years. It has run virtually everyday. Have had no issues except a certain time of year in front a floor to ceiling window which bright sunshine probably was messing with the side sensor. After about a week that stopped.
My sister has a Roomba and a large house and I was the one to have to set up her home for it. I certainly know the difference between Neato and Roomba. Personally for me, I prefer Neato with it's mapping and quicker cleaning than the randomness of a roomba. I am not knocking roomba at all. Roomba would work perfectly for me also. I like the efficiency of the Neato over Roomba. That's my personal preference.
I had a friend with all wood floors buy a Roomba. I set up his house for it and he loves the roomba. In two years his Roomba only got lost twice. He loves it!
Anyway, the main point is I upgraded to 3.1 firmware and Neato is doing exactly what I wanted (added corner cleaning) and is still working perfectly.
Love my Neato! who is named Bubba.
I generally lurk and not post, so this is probably the most you will here from me. I really don't see any great improvement in the older unit that I have, with any further firmware upgrades. Of course if by some miracle a new firmware is created to make my Bubba better, I certainly will welcome it. I just don't see any other improvement to the XV 11 or 12 whichever I have.
Happy in Denver with Bubba!
