What if my RoboVac stops in the middle of cleaning with Three Beep Error?
If your RoboVac stops with a 3-beep error, please confirm whether it is with a flashing or solid red indicator.
* If flashing red indicator (drop sensor error), please try following and let us know whether it helps:
Check whether the issue happens only in a certain area, like strong sunlight or black-colored carpet.
Make sure the vacuum is charged. Turn off the main power switch on the bottom of the vacuum and turn it back on in 1 minute.
Clean all 3 drop sensors with a clean dry cloth.
* If solid red indicator (suction fan error), Please let us know if this helps:
Empty the dust collector, clean the suction inlet and air passage, and check to make sure the filters are properly aligned and in place (some models have 3 filters: blue prefilter, white high-performance filter, and black sponge filter, some models have a unibody filter set).
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 area. Make sure there is air passing through that area after starting the vacuum.
Make sure the vacuum has not run over any liquids. If there are any parts that have gotten wet, make sure they are completely dry before re-installing. If water went into the suction fans, the internal parts would be damaged.
