Introduction
Your robot navigates through a combination of random movements and sensors to guide it around a room. This guide will show you how to access two of these senors in the event that they fail and need to be replaced. Faulty senors will result in sporadic robot movement, more frequent collisions, and the robot eventually flashing error codes.
Remember to periodically clean all sensors with a dry microfiber cloth to keep your R75 performing properly.

Curious if anyone ever saw the WiFi die in these? I cannot get the shark WiFi to show so I can add it to the network. I press both the bottoms and the icon flashes but shark WiFi never shows so the app can continue.
