AEG 90027751200 – Plus.Parts® Upkeep Kit

The AEG 90027751200 is a catalog number for the AEG QX9-1, sold through specific retail channels while sharing the same 21.6V motor platform and dual filter architecture as the broader QX9-1 range. The BrushRollClean technology, the self-cleaning mechanism on the LED motorised nozzle, depends on the motor’s available airflow. A loaded pre-motor filter restricts that airflow, raises the current the motor draws to maintain suction, and generates heat in the battery pack that shortens runtime per charge. Clearing the filter stack on the correct schedule is therefore not just about filtration quality: it protects both the motor and the battery from the secondary effects of airflow restriction. AEG specifies monthly washing and quarterly replacement for both filter stages on every QX9-1 variant.

This upkeep kit contains Plus.Parts® components matched to the QX9-1: 3 washable pre-motor filters, 3 washable post-motor filters, and 1 cleaning tool. All dimensions verified for the QX9-1’s dual filter housing. Seven components, both filter stages covered in one order.
