Beatbot Ultrasonic AI pool robot

Came with the pool when we moved in last summer and worked up until one of the plastic gears broke. Couldn't find the replacement part online, so went ahead and purchased a new robot. Free for the taking either for parts or if someone is good at 3D printing, you can maybe remake the broken part. (Part that is broken is the plastic part that attaches/spins the brushes-it's circled in the 3rd picture)
