Symptoms
- Charging light doesn't turn on when docked or plugged in
- Vacuum shows no charge after hours on the charger
- Charging light flickers or blinks an error pattern
- Vacuum charges but doesn't hold power long
Likely causes
- CommonDirty or misaligned charging contactsDust or misalignment between the vacuum and charger prevents a good electrical connection.
- CommonFaulty outlet or power adapterA dead outlet or damaged charging brick can look identical to a battery problem.
- PossibleBattery fully depleted below its safe recovery thresholdSome batteries need an extended slow charge to recover from a very deep discharge.
- PossibleFailed battery cellsAfter years of use, individual battery cells can die and prevent charging entirely.
- Less commonFaulty charging circuit boardThe internal circuit that manages charging can fail independently of the battery.
What to do
- Test the outlet with another device to rule out a dead outlet.
- Wipe the charging contacts on both the vacuum and the dock or charger plug.
- Confirm the charger cable and adapter show no visible damage.
- Leave the vacuum charging for several hours in case it needs to recover from a very low charge.
- Check for a status light pattern in the manual that indicates a specific error code.
- Try charging the battery on a different compatible charger if you have access to one.
- If nothing charges after several hours with a known-good outlet and clean contacts, the battery or charging circuit likely needs replacement.
Tools and parts
- Dry cloth
- Another device to test the outlet
