Robotic vacuums are miracles of modern technology, but they also have an unexplained affinity for cords. If there is one cord out in the open in your house, your DEEBOT OZMO 610 will find it... And then run over it. And then get tangled with it. So, before you start your first session, quickly make sure there are no cords waiting to be heartlessly mangled. Also, you may have noticed your DEEBOT is low to the ground and has small driving wheels. So, while it is perfectly suited for low-pile carpet, you may want to be careful on shag carpet. Sorry.
