Possible Causes

Clogged floor head spray nozzles, blocked internal spray manifold, kinked solution hose at pivot joint

How to Fix / Troubleshooting

Safety: Unplug the unit and depressurize by squeezing the trigger.

  • Test handheld tool: Confirm that the handheld tool sprays normally. This indicates the pump and main lines are working.
  • Remove floor head: Detach the floor head from the main body or wand. Disconnect the solution hose quick-connect.
  • Clean nozzles: Remove the spray bar or individual nozzles and soak them in warm water. Use a soft brush to remove deposits.
  • Check pivot hose: Inspect the short hose section at the swivel joint for kinks or internal collapse. Replace if necessary.
