iRoomba 560 500/600/700/800 Series Circle Dance 9-beep Problem Overview

If your roomba is going backwards and spinning in circles and gives you a 9 beep error code and is one of those above series of roombas it is very likely to have a problem (known) with it's bumper sensor.

To summarize the problem: there is a bad IR diode in the machine, and you can fix it.

Note: I have worked with this person (from tutorials and with parts) on a few ocassions and he has quickly sent me the parts I needed perfectly and quickly. His tutorials are very good too.

2. Do you feel comfortable taking apart a machine under guidance? If no, then let someone else. See Solution C.
3. Have you ever worked on any machine (desktop/laptop) before? If no, then let someone else. See Solution C.

Step 5: Fix IT!

Solution A/B: [order the pre-soldered parts]

Soldering tiny things and parts on breadboards is a skill not every has. It takes calm hands, patience and care. You can burn yourself, and might anyway. Depending on whether you're patient or not or want to save money you can do A or B.
.
Solution D: [you're personally fixing the it]

If you can solder, then you're good. The tutorials will help you through everything.
