Concerning cleaning area, we just use two unrestricted 595's as a simple solution. They start from different locations and double the cleaning in the same amount of time.
Thanks. I think throwing my 560s some new batteries will definitely be at least a holding tactic.
I actually have two 560s, the first bought pretty much exactly 9 years ago give or take a few weeks. That one actually did have an issue within a year or two when the brush unit locked up and I used that as an excuse to put in a new brush/motor module with the fancy metal bearings mod (I forget where from) and that has been perfect ever since.
I was so impressed with my first 560 that I got a second one about 6 months later that is still on its original unmodified brush unit. I have a hard virtual wall (as opposed to a "soft" lighthouse that a Roomba can get through) that splits my apartment into front (living) and back (sleeping) areas. My first (modified) Roomba lives in the living area and cleans that in the early mornings before I get up. My second Roomba lives in my bedroom and cleans the bedrooms and bathrooms in the daytime when I'm up and working in my home office.
My setup works really well for me. Even with a new fancy smart-navigating I-can-clean-your-whole-house-in-one-go Roomba added to my menagerie I think what I would do, at least initially before I got a feel for the capabilities of whatever new Roomba I might have purchased, would be to move my original modified Roomba to the bedroom area, retire the newer 560 to keep for parts (the older modified one runs more smoothly still thanks to those metal bearings), and put the all-singing-all-dancing newer one in the living areas.
Even if the newer models can keep track of where they've cleaned and what is left to clean in a whole house there's still the issue of finite dustbin capacity and, at least with my 560s, suction dropping off as the bins get fuller, so the general concept of splitting my apartment into two to reduce the amount of dust each one is likely to collect in a single mission still seems like a strategy that I would want to keep going forward. The only thing that might derail that (in a good way) is if the next Roomba has a much more sophisticated docking station that can empty the Roomba's bin itself. If that were to happen my original question of can a 980 navigate itself away from the dock at the start of a mission before starting to clean would be pretty critical though because a fancy new docking station like that would presumably be much bigger and almost certainly wouldn't fit under the sofa/couch which is where the 560 in my living area currently lives. I would definitely want to put that docking station in a utility room where it doesn't clutter up the living spaces.
Hopefully 2018 will be an exciting year for Roomba. I have quite a lot of brand loyalty given how much use I've had out of my 560s and I still love them to this day.
