  A flashing red indicator light on your EUFY RoboVac suggests a few potential issues. It could be hanging over a ledge or trapped, in which case you should turn it off and restart it in a new location. The bumper might be stuck; tap it several times to dislodge any debris. The drop sensors may be dirty, so gently clean them with a dry cloth. Lastly, the power level could be too low; manually charge the RoboVac for at least 5 hours.

  If your EUFY Robot vacuum cleaner for home cannot be activated, there might be several reasons. First, ensure that the power switch is in the ON position and that the battery is charged. If you are using a remote control, replace the batteries (2 AAA batteries), make sure the remote control is within 3m range from RoboVac, and point it directly at RoboVac. Also, check whether RoboVac is trapped or stuck on an obstacle or whether the power level is too low.

  A solid red indicator light on your EUFY RoboVac indicates a problem with one of its moving parts. The wheel could be stuck, so turn off the RoboVac and remove any hair or debris from the wheel. Similarly, check the side brush and rolling brush for obstructions. Also, the suction fan might be jammed; turn off the RoboVac, then remove and empty the dust collector.
