Choosing the Right Leaf Blower
The wrong leaf blower makes autumn cleanup slower and more frustrating than raking by hand. The right one clears an entire garden in 20 minutes. Here's how to choose.
Key Specifications: What Actually Matters
Air volume (m³/h or CFM) — the volume of air moved. More CFM = more leaves shifted per second. This is the most important specification.
Air speed (km/h or MPH) — the velocity of the airstream. High speed is good for dislodging stuck wet leaves, but volume does the clearing work.
Noise (dB) — petrol blowers run 94–100 dB; cordless 60–75 dB. For suburban gardens near neighbours, noise level matters.
Handheld Blowers
The most common type. Petrol-powered handheld blowers (25–50 cc) deliver 400–750 m³/h and are the go-to for general garden use. Cordless battery handhelds (40–80 V) are quieter and increasingly capable — the best models now match medium-size petrol blowers in airflow, with 30–45 min run time.
Best for: Gardens up to 1,500 m², hard surfaces (paths, patios, driveways), occasional use
Backpack Blowers
The engine/battery sits in a backpack frame, reducing arm fatigue during long sessions. Output ranges from 600–1,400 m³/h. The professional choice for gardens over 2,000 m² or for anyone doing multi-hour blowing sessions.
Best for: Large gardens, professional grounds maintenance, orchards, long driveways
Combination Blower-Vacuums
Switch between blowing and vacuuming modes. The vacuum mode collects leaves into a bag (with a shredder ratio of 10:1 or better). Slower than a pure blower but eliminates a separate collection step.
Best for: Smaller gardens where you want to collect rather than pile, limited storage space
Petrol vs Battery: The 2024 Reality
Battery technology has closed the gap significantly. A 56 V or 80 V cordless backpack blower from a quality brand now matches or exceeds mid-range petrol performance — without fumes, with lower noise, and with zero maintenance. The limitation remains run time (30–60 min per charge) and charging time. For professional daily use, petrol still wins. For residential weekend use, battery is increasingly the better choice.
FAQ
What CFM do I need to clear wet leaves?
Wet leaves are heavy. You need at least 450 m³/h (400+ CFM) and a high air speed (250+ km/h) to move saturated leaves efficiently. Handheld petrol blowers in the 30–50 cc range handle wet leaves well.
