Leaf Blowers Buying Guide: CFM, MPH, Batteries, and What Actually Matters

CFM vs. MPH: What Each One Actually Tells You

CFM (cubic feet per minute) measures the volume of air moved.

This is the number that predicts how well a blower handles heavy, wet, or large piles of debris.

The Toro PowerJet F700's 725 CFM is the highest in this category, and it shows most clearly on wet leaf piles that lighter blowers struggle to move.

MPH (miles per hour) measures how fast the air stream travels.

Higher MPH helps push light, dry debris further in a single pass but doesn't predict performance on heavy or matted debris the way CFM does.

Battery Voltage and Amp-Hours

Voltage (40V on Ryobi and Greenworks, 56V on EGO) reflects the battery system's design, not a direct performance guarantee on its own.

What matters more in practice is the combination of voltage, motor design, and battery amp-hour (Ah) rating.

Amp-hours directly determine runtime.

A 5.0Ah battery, like the one included with the EGO LB6504, holds meaningfully more charge than a 2.0Ah or 4.0Ah battery on the same platform, translating to longer runtime at the same power draw.

When comparing cordless blowers, look at the actual CFM rating and the actual runtime figure (usually listed in minutes), rather than assuming a higher voltage number alone means a better blower.

Corded vs. Cordless: The Real Cost Comparison

A corded blower like the Toro PowerJet F700 has no battery to buy, charge, or eventually replace.

Over several years, that avoids a real recurring cost, cordless tool batteries typically lose meaningful capacity after 3 to 5 years of regular use and need replacement.

A cordless blower trades that long-term cost for convenience: no cord to manage, no outlet dependency, and often a shared battery platform across other yard tools you may already own.

For a household already invested in a battery platform, cordless is usually the more convenient long-term choice.

For a first leaf blower purchase on a tight budget, corded delivers more raw performance per dollar upfront.

Noise Ratings

Decibel (dB) ratings aren't always prominently listed, but they matter for anyone with close neighbors or who does yard work early or late in the day.

Standard cordless blowers typically run in the 65 to 75 dB range during normal use.

Models built specifically around noise reduction, like the Ryobi 40V Whisper Series, run quieter at matched CFM output.

Gas blowers commonly exceed 75 to 90 dB, part of why many municipalities and HOAs now restrict gas blower hours specifically, while cordless electric models rarely face the same restrictions.

Weight and Ergonomics

Handheld blower weight in this category ranges from roughly 5 to over 6 lbs with a battery installed.

That range feels small on paper but adds up over a 30 to 60 minute session, especially for elevated or one-handed work like gutter cleaning.

A cruise control or trigger lock feature, like the one on the Ryobi Whisper Series, reduces the physical demand of a long session independent of the blower's actual weight.

Warranty Coverage

Warranty length varies more than most buyers expect in this category, from 1 year on typical budget cordless tools to 5 years on the EGO LB6504's tool warranty.

For a seasonal tool that may sit unused for months at a time, a longer warranty is a meaningful hedge against defects that don't surface immediately.
