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.
Here, you have misused the reminder bullet. The note bullet would be better in this case; I would also say how to turn it off, rather than just to do it. Avoid locate steps, and instead, move straight to the information about what to do. Use markup on the images to indicate where the component is. Be careful about using “remove” without other information about how to remove it, especially if there are multiple ways to remove something.
