If your RoboVac stops with a 2-beep error, please confirm it is with a flashing or solid red indicator.

If flashing red indicator (bumper error), please try following and let us know whether it helps:

- Tap/pull/shake the bumper vigorously to dislodge any debris underneath and make sure it is flexible/can spring back.

- Clean the bumper surface with a dry clean cloth.

- If the above 2 steps did not help, check whether the bumper is symmetric, or if one side sinks down or pops out. On the bottom of the vacuum, there are screws on each side of the bumper to fix it. If possible, loosen the screws and re-assemble the bumper. You can refer to this video: How to Replace Bumper of RoboVacs

Please mind the cord connecting the bumper to the machine when removing it. 

If solid red indicator (side brush error), Please let us know if this helps:

- Make sure to remove the side brushes to clean them out, and clean the connector on the vacuum.

- If you have a spare pair of side brushes, please replace them and let us know if the issue can be fixed. If you don't have a new pair, then exchange the 2 side brushes. Make sure there is a clicking sound when you snap the side brush onto the holder.

-Replacing the side brush assembly might fix the issue. You can refer to this video How to Replace the Side Brush Motor of RoboVac to see if you could replace it yourself or ask a friend to replace it for you.
