CFM wins for blowing leaves because volume of air moved — not speed alone — is what actually displaces a pile of wet leaves or debris across a driveway.

MPH measures how fast air exits the nozzle; CFM measures how much air moves per minute. For leaf clearance, you need both working together, but CFM does the heavy lifting. A blower with high MPH and low CFM produces a concentrated jet that lifts a small area without shifting the mass around it. High CFM pushes a wider column of air that sweeps leaves in bulk — which is why CFM is the number that separates a patio blower from a yard blower.

  • The Heinpro 500 CFM blower pairs 500 CFM with 150 MPH — enough to clear wet leaves and damp driveways.
  • The Heinpro mini blower reaches 200 MPH but moves significantly less air volume, making it better suited for workbench or tight-space cleanup than full yard leaf clearance.
  • CFM (cubic feet per minute) measures total air volume moved; MPH measures exit velocity at the nozzle tip.
  • For wet or matted leaves, CFM below 400 typically struggles to move debris in bulk regardless of MPH rating.
