Cordless vacuum runs for only 1–3 minutes then stops, with no error code shown.

Safety first: Remove the battery before handling.

Steps:

• Confirm charge: Fully charge the battery until the charger indicates full.
• Measure run time: Use the vacuum continuously on normal mode and time how long it runs from full to cut-out.
• Compare to spec: Check your Hoover model’s manual for expected run time (often 20–40 minutes). If the actual time is less than half of the specification, the battery is worn.
• Inspect battery: Check for swelling, cracks, or overheating during use. If present, stop using immediately.

Resolution: Replace the battery with a genuine Hoover pack. Battery cells are not user-repairable.
