Nice tutorial thanks.....that's a nice apple art wall you have there..... can you explain how you did it? We have all those boxes, too and I just can't throw them away :))
This should answer your question best: store.irobot.com/default/parts-and-accessories/roomba-accessories/i-series/dual-mode-virtual-wall-barrier/4636429.html
The 985 is a really good machine. The key difference is the mapping technology. The 985 maps out the floor every single time it runs, deleting it after the job is done. The i7 saves the map, and allows you to designate what rooms you want it to clean. As long as you’re fine with your roomba going everywhere (except for the virtual walls) then it shouldn’t be that big of a difference. Besides that there aren’t any huge differences between the two.
No, unfortunately not. You can leave the virtual walls wherever you want, and the machine will recognize them, but it doesn’t save any mapping from previous cleanings. If you want that and don’t want to spend the money on a nicer Roomba you can always take a look at brands like Neato which includes mapping (that saves room dimensions) every cleaning.
