The unit is signaling a charging error. The three-beep pattern means it's not making proper contact with the charging base.
- Power off the RoboVac using the switch on its underside.
- Inspect the metal charging contacts on both the vacuum and the charging base. Clean them with a dry cloth to remove any dust or debris.
- Reposition the charging base. It needs a minimum of 3 feet of open space on each side and in front of it. Ensure it's on a hard, level surface and pressed flush against a wall.
- Power the RoboVac back on and manually place it on the base, aligning the contacts. It should start charging silently.
IF THAT DIDN'T WORK: The issue could be the power adapter or the base itself. Try using a different power outlet. If the problem persists, contact eufy customer service for a repair or replacement of the charging base.
HEADS UP: Always ensure the charging base's area is clear. Obstructions or an uneven floor can prevent proper docking and cause this error.
