Coredy r550 Robot Vacuum

Coredy r550 Ultra Robot Vacuum Cleaner from Amazon. Used for about 2 years and works great, just decided to upgrade. Just replaced the battery. Comes with additional replacement parts for filters, brush roll, sweeper feet. Wiped down and cleaned to look brand new. Comes with charging station and remote control. Does not have any app connectivity or mapping features. Determines its patch by moving around and using sensors to turn when it bumps into something. Worked great on my tile floors with lots of hair from shedding dog.
