The battery leaf blower market has exploded. There are dozens of models across a wide range of prices, and the spec sheets are full of numbers that don't always mean what you think they mean. If you're buying your first cordless blower — or upgrading from a disappointing one — this guide cuts through the noise and tells you exactly what to look for.
Step 1: Understand the Two Specs That Matter Most
CFM (Cubic Feet per Minute) is the volume of air the blower produces. Think of it as the width of the air stream. Higher CFM means you move more debris with each pass. For light residential use, 300 to 450 CFM is adequate. For moderate suburban yards, 450 to 600 CFM is the sweet spot. For heavy-duty cleanup — wet leaves, large properties, commercial work — look for 600 CFM and above.
MPH (Miles per Hour) is the speed of the air at the nozzle tip. Think of it as the force that dislodges stuck debris. Higher MPH means you can peel wet leaves off pavement and drive stubborn material forward. Under 120 MPH is fine for dry debris. 150+ MPH handles most conditions. 180+ MPH is professional-grade force.
The ideal blower delivers high marks in both. CFM without MPH moves a lot of air gently. MPH without CFM concentrates force on a tiny area. The best cordless blowers — like the Greenworks 80V 770 CFM Leaf Blower at 770 CFM and 180 MPH — deliver strong performance in both categories.
Step 2: Choose Your Voltage Tier
Voltage determines maximum power. Higher voltage means more potential airflow and more sustained performance under load.
18V to 24V: Light-duty. Patios, garages, car detailing, quick post-mow sweeps. The Greenworks 24V Brushless Blower fits here — compact, lightweight, and part of the 200+ tool POWERALL ecosystem.
36V to 48V: Mid-range. Standard suburban yards with moderate debris. The Greenworks 48V 600 CFM Blower is the all-rounder in this tier.
56V to 80V: Premium. Large yards, wet conditions, heavy leaf volume. This is where the Greenworks 80V 770 CFM Leaf Blower and 80V 780 CFM Backpack operate — gas-rivalling performance without gas.
Step 3: Brushless vs Brushed Motor
This matters more than most people realise. Brushless motors are more efficient, generate less heat, last longer, and deliver more consistent power throughout the battery cycle. They also extend battery runtime by 15 to 25% compared to brushed motors doing the same work.
Brushed motors are cheaper to manufacture and appear in budget blowers. They work, but they wear out faster and waste more energy as heat.
For any blower you plan to use regularly for more than a season or two, brushless is worth the investment. Every Greenworks blower at the 48V tier and above uses a brushless motor. The 80V 770 CFM model features a brushless motor that delivers consistent airflow from the first trigger pull to the last percentage of battery charge.
Step 4: Variable Speed Control
A blower with only an on/off switch runs at full power all the time. That wastes battery on light tasks, creates unnecessary noise, and gives you no precision for delicate jobs like car drying or workshop cleaning.
Look for a variable speed trigger that lets you dial airflow up and down by how hard you squeeze. This gives you precision at low speeds and power when you need it. The Greenworks 80V 770 CFM includes a variable speed trigger for exactly this kind of flexibility.
Step 5: Handheld vs Backpack
Handheld: Lighter, cheaper, faster to grab for quick tasks. Best for properties under a third of an acre or blowing sessions under 20 minutes. The Greenworks 80V 770 CFM weighs just 5.95 lbs without the battery — one of the lightest in its power class.
Backpack: Weight distributed across shoulders and back. Best for large properties, extended sessions, or anyone who experiences arm fatigue with handheld models. The Greenworks 80V Backpack Blower delivers 780 CFM at 205 MPH with zero arm strain.
Step 6: Battery Ecosystem Compatibility
Before buying a blower, check whether the battery platform is compatible with other tools you own or plan to buy. Buying into a shared ecosystem saves you from purchasing duplicate batteries and chargers.
Greenworks offers several battery platforms with full cross-tool compatibility. A 24V POWERALL battery from your blower works in your trimmer, drill, and mower. An 80V battery from your blower works in your mower, chainsaw, and snow blower. One investment covers multiple tools.
Step 7: Noise Level
If you have close neighbours, live in a community with noise bylaws, or simply value your hearing, check the blower's decibel rating. Gas blowers typically hit 90 to 100+ dB. Quality battery blowers operate between 60 and 75 dB — dramatically quieter. Lower dB means you can blow earlier in the morning, later in the evening, and without hearing protection.
Step 8: Warranty and Support
A blower is a multi-year investment. Look for at least a 3-year warranty on both the tool and the battery. Greenworks offers a 4-year warranty on its 80V products — covering both the tool and the battery — one of the strongest in the industry. Canadian-based support through the Holland Landing, Ontario headquarters means local service and faster warranty resolution.
