Possible Causes

Incorrect or incompatible floor head attached, Damaged ID resistor or chip in floor head, Broken ID line in wand wiring, Faulty accessory detection circuit on main PCB

How to Fix / Troubleshooting

Safety first: Remove the battery before changing attachments.

  • Use original accessories: Ensure you are using the original Proscenic motorized floor head designed for your model. Third-party heads may not be recognized.
  • Clean connectors: Wipe the electrical contacts on the floor head and wand with a dry cloth.
  • Test another powered tool: If another powered attachment (mini motorized brush, etc.) works, the main floor head is likely faulty and should be replaced.
  • Test floor head on another unit (if available): If the head works on another compatible Proscenic vacuum, your main body or wand has a detection circuit issue and may need repair.
