I bought this product because I thought it would be able to transition between my tile and wood floors over a small bump but it always gets stuck. I had hoped I could mop my kitchen, dining and living areas with this one device since it has a long run time. The old Braava 380 wouldn't even try to push over the small bump between floor types, so it never got stuck. Also the old Braava could be placed in any room and would clean. This one, due to its mapping abilities, seems to just be able to mop in one area. The Braava 380 could use Swiffer cleaning pads for dry cleaning, for this one you can only use its special pricey cleaning pads.
