Inleiding

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.

  1. Make sure the robot is shut off by pressing the power button on top. Flip the R75 over so that the underside is facing up. Using a Phillips #1 screwdriver, remove the 4mm screw in the battery cover.

  6. Remove the rubber end cap indicated by the red circle. This step is not needed for a replacement. However, it is important for maintenance. Hair will build up in this area over time, and will cause error messages to pop up, as well as stopping the R75 from cleaning and moving.

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.
