I have a Neato XV21 for a few years now. It’s specific for pets,I have 3 cats. I’ve replaced batteries and brushes and it still works great. I’ve had Roomba’s and they haven’t compared. It’s not quite, but I schedule to run when I’m not at home. I have a central vac system and own Dyson broom sticks and uprights. The robot vacuums go where you wouldn’t typically vacuum. Under beds and under furniture. A great investment but you’ll need to gather up wires and address certain barriers.
