CFM moves leaves, MPH lifts them · review
The high-volume Trivac: 600 CFM at a much lower air speed, with a 50-liter bag, for $117.
At 600 CFM, the WG512 moves about 70% more air than the WG509, at about a third of the speed. That helps with piles of dry leaves.
The bag grows to 50 liters and the mulch ratio falls to 16:1. For most yards, the cheaper WG509 is the better all-rounder.
Wear eye and hearing protection, and keep the air stream away from people and pets. Noise figures on listings do not always say whether they are sound power or sound pressure.

CFM is volume and MPH is speed. This blower moves a lot of air slowly, which pushes dry leaves but lifts less wet, stuck debris.
The bullet gives 600 CFM and the table adds 70 or 75 MPH.

The live figure beside a product went and asked the shop for it the moment this page opened; any amount written into the text has not moved since the sentence was drafted, and it is the first of the two that counts.
