Hoover Bottom Plate - UH70120 Windtunnel T Series - CH53005 - CH53010 2252 The board governs the unit'sThis genuine OEM Hoover bottom plate (Part #303829001) fits the UH70120 Windtunnel T series and related Hoover models. The bottom plate closes the underside of the cleaning head and sets the clearance around the brush roll.

Fitting the correct factory plate restores proper airflow and effective pickup. Fits: Hoover CH53005,
