RYOBI 40V LEAF VACUUM/MULCHER (RY40405 / RY404150) Fix

Replacement Lawn and Leaf Bag

The bag acts as the exhaust filter for the vacuum; over time, microscopic dust particles saturate the fabric pores, creating high static back-pressure. This restriction prevents the impeller from effectively drawing air through the intake tube, resulting in a significant drop in suction velocity.

Vacuum Tube Assembly

Air leaks at the interface between the vacuum tube and the motor housing disrupt the venturi effect required for suction. Additionally, these tubes house the safety interlock tabs; if warped or chipped, they fail to fully engage the internal microswitch, preventing the brushless motor from reaching its maximum CFM output.

Metal Impeller

Physical damage to the impeller vanes from ingesting stones or heavy debris can alter the aerodynamic profile of the fan. Even slight deformation of the metal blades reduces the centrifugal force generated, leading to an immediate and permanent loss of vacuum pressure.
