Cordless Shark vacuum shows an error when the handheld unit is attached to certain powered accessories (e.g., mini motorized pet tool)

Safety first: Remove the battery before attaching or detaching powered accessories.

• 1. Test vacuum without accessory: Run the handheld unit alone. If it operates normally, the fault is likely in the accessory.
• 2. Inspect accessory brush: Remove hair and debris from the mini motorized tool or other powered head. Ensure the brush spins freely by hand.
• 3. Check accessory connector: Look at the electrical contacts on the accessory and handheld unit. Clean gently with a dry cloth and ensure no pins are bent.
• 4. Test another powered accessory: If available, connect a different powered tool. If only one accessory triggers the error, that accessory is defective.
• 5. Replace faulty accessory: Powered accessories are not typically user‑repairable. Replace the mini motorized tool or other faulty head with a genuine Shark part.
