Leaf Blower FAQS
Do you make Gas Blowers?
No. All Greenworks leaf blowers are cordless battery-powered blowers or corded electric blowers.
Is a battery powered leaf blower quieter than gas?
Yes! Electric and battery-powered leaf blowers are generally quieter than gas models.
What is more important MPH or CFM?
Both CFM and MPH have their benefits—it depends on which type of blower you’re looking for. MPH is an abbreviation of miles per hour. This denotes the speed at which the air exits the blower. Higher MPH figures produce large pressure changes at the blower inlet. Therefore, a higher MPH is beneficial when looking at blower/vac units as higher airspeed helps move heavier debris. CFM is an abbreviation of cubic feet per minute. This denotes the volume of air displaced by the blower. High CFM units tend to move large air volumes at relatively low speeds, allowing large areas to be swept and cleared in a shorter amount of time. Axial blowers/dedicated blowers benefit more from a higher CFM and is more desirable for these units.
What is the most appropriate blower for my property?
Generally, electric leaf blowers have a CFM falling somewhere from just under 200 to 400. If your property is one acre or more, you'll probably want a leaf blower with a CFM between 400 to 700.
Can I dry my car or blow snow off my driveway?
We do not recommend using this blower for any task other than leaf blowing.
What is the difference between a hand blower and backpack blower?
Hand-held blowers are held in your hands, backpack blowers are carried on your back. Hand-held blowers are often the less expensive than backpack blowers and have smaller motors to ensure they're not too heavy to carry. But, because the motor is smaller, they have less power. These blowers are great if you have a small yard, but they can be taxing if you’re spending 30-40 minutes on the job. Backpack blowers provide more power than handheld tools. They have the added benefit of being more ergonomic because you're aided by your trunk in maneuvering the blower, so you’re not relying solely on arm strength. Backpack blowers are better for tackling large jobs, but they’re also more expensive than hand-held blowers.
How do I use the mulch function with my blower/vacuum?
When mulching leaves, the Blower/Vac must be in TURBO-MULCH mode. Items such as small leaves and twigs will be mulched as they pass through the fan housing. We recommend emptying the bag after each use to avoid deterioration and the obstruction of air flow which will reduce the performance of the mulcher.
Why is dust coming out of my collection bag while using my Blower?
This is normal. There are tiny holes in the collection bag that are necessary for its operation. They allow very small particles of dust to pass through.
What debris will the Blower/Vacuum collect?
The Blower/Vacuum is designed to collect lightweight, low density leaves. Other forms of garden debris can be collected but solid objects such as toys, twigs, stones, pinecones, etc. should be avoided.
Why is my vacuum not collecting garden debris?
If your blower is not easily picking up leaves, ensure that the nozzle is close enough to the leaves/debris. Also, make sure that the mode indicator is on the correct setting. Press the low/high switch to increase the speed options. The unique design of the blower-vac means that only lightweight, low density objects such as leaves and garden debris will be collected. It’s worth noting, higher density objects such as stones and sticks will not be collected. If you're finding that the unit is still not picking up garden debris, it may be necessary to remove the blower tube or mulcher tubes to clear a blocked tube or impeller. Please be sure to remove the battery or unplug the unit before checking the tube or impeller.
What blower can I use for hard surfaces?
The best blow power for removing heavy or wet organic materials from soft surfaces like grass, dirt, or sand will come from a corded electric blower or from our 80V PRO blowers. The 80V 580 CFM Brushless Backpack Blower offers 580 CFM, while the 80V 500 CFM Cordless Brushless Axial Blower offers up to 500 CFM—both pack plenty of power for hard surfaces.
What is the battery life and how do I maximize it?
To get the most life out of your battery, you should remove it from the charger once it has finished charging. The problem with overcharging is the potential damage it can cause to the battery that can shorten its lifespan. Of course, be sure to read your tool’s instructions as it may indicate that storing your battery on the charger is fine.
