Maintenance Tip: Preventing "Air-Lock"

When replacing your detergent pump, always ensure the intake lines are primed and free of air bubbles. A "dry" pump can lead to inconsistent chemical dosing and may trigger a cleaning alarm on your robot. We recommend checking the suction filters in your soap drums at the same time to ensure no debris enters the new pump.
