We usually don't recommend our customers to disassemble the RoboVac. However, sometimes some debris might get into the suction fans, causing suction fan alerts or loud noise.

You can try this at first:

- With the dust collector removed from the unit, hold the vacuum upright with the bumper facing up, the suction "hole" facing downwards. Shake out any debris that might be stuck in the suction fans inside the machine.

If the debris cannot be shaken out,  you can try disassembling the vacuum to clean the suction fans from the internal. While it might look a little difficult seeing it for the first time, it is much easier than expected. You can have a look at the video links below to see if you could disassemble it.
