I've been using Roomba vacuums for years and upgraded to the 960 in 2018. I purchased the Braava to 'mop' the floor after the 960 vacuums. It doesn't cope with heavy stains or spills but is very effective at removing light marks (dog footprints). It won't clean as large an area as the Vacuum so the Imprint™ mapping that lets me tell it to mop just the kitchen is very useful. Imprint is far better than using the old 'virtual walls' although it is still glitchy and won't update maps as the robot explores more. It is incredibly slow and the noise is somewhat irritating when it sprays cleaning fluid but overall it's more useful than I expected so I am pleased.
