Depending on its intended use, a cordless leaf blower with a CFM between 400-700 should be powerful enough to greatly ease your fall yard chores.
400 CFM minimum if you're using it to move leaves. Preferably 600+.
450 cfm and 600 cfm are directly comparable, with 600 cfm being 33% more air by volume than 450 cfm. This measurement down not take into account the velocity of the air coming out of the nozzle.
250 CFM is enough to blow sidewalks, small yards, and most debris. 2 Ah battery lasts for about 15-20 minutes continuous and charges in about an hour. The blower is very lightweight and easy to use. Indicator lights to show charge volume on the battery.
You may find that your model requires anywhere from 4 amps (for light, corded models) up to 12 amps (for heavy-duty cord-free options), with an average range of about 7-12 amps. The more powerful the leaf blower is, the more amps you can expect it to draw to get the job done.
Internet says anything north of 400 CFM. I've used the battery powered Milwaukee blower at work and it did pretty good. Was not too heavy... Maybe ten pounds with the large battery, you can drop that weight if you use smaller batteries. And you could lock it powered on.
The Toro 60V Max Brushless Cordless Leaf Blower has a similar handle and overall vibe as our top corded pick, which is a good thing. But compared with the other cordless picks, it doesn't have the same power and it has a mid-range run time of about 22 minutes.
High CFM: If you need to clear large areas with a lot of leaves and debris, a leaf blower with a high CFM is more efficient. It will move more at once, saving you time and effort.
Experience exceptional performance with just the flip of a switch, without the hassle of gas or cords. Achieve 10 minutes of runtime using an 18V ONE+ 2Ah battery.
If you have a small yard with little debris, choose one with 200-400 CFM. Our knowledgeable sales staff can help you determine a good CFM and MPH for your needs, whether for commercial or residential landscaping. (There are commercial leaf blowers with a CFM of up to 3,000!)
Most battery blowers run for 20 to 100 minutes on a single charge, but some last for hours while others lose power after just a few minutes. With up to 5 hours of run time, the MAKITA CBU01 with a backpack power supply has the longest battery life.
200-400 CFM: Great for homeowners with average-sized yards. This power level can be found in 18-24V leaf blowers. 400-600 CFM: Perfect for people with larger lots such as homesteaders, landowners, and property managers. This power level can be found in 40V leaf blowers.
The line trimmers and blowers used are all 4-stroke equipment, which is significantly better than the 2-stroke engines found in most gas-powered leaf blowers. Four-stroke engines offer more complete combustion and produce less air pollution.
As you are comparing cordless leaf blowers, be sure to check how long they can run on one charge and consider whether that will give you enough time to cover your yard, driveway, and patio.
The Husqvarna Leaf Blaster 350iB simply blew the other competition away when it came to nearly every metric that we tested. While on turbo at 5" from the nozzle, the blower ran a whopping 1105 CFM at 153 mph, giving more than enough muscle for bigger and more demanding jobs.
Store your RYOBI batteries in a location that's sheltered from extreme temperatures and humidity. Avoid exposing to direct sunlight, rain, or other environmental extremes. Running the tool at full power continuously when it's not necessary can drain the battery faster. Use the appropriate power setting for your task.
The short and simple answer is that “Ah” stands for “amp-hour” or “ampere-hour.” The general idea behind the amp-hour is to give consumers a rough idea of the length of a charge cycle for a battery. For example, a 4Ah battery should last twice as long as a 2Ah battery.
With both blowers using a 4.0 Ah battery, the 550 CFM blower has a runtime of 75 minutes if you're using the variable speed on low. The 600 CFM blower has a runtime of up to 22 minutes.
The larger the space, the higher the fan CFM must be in order to efficiently cool a room. CFM for fans is a critical measurement for determining the right fan for your space. If the CFM is too low, the room will be unable to be cooled and undermine any energy efficiency of the fan.
The speed of the air as it leaves the leaf blower is measured in miles per hour (MPH). This is another way to measure how powerful the leaf blower is. A leaf blower that's capable of blowing air at faster speeds will be more powerful and be able to blow away heavier objects.
You should look for a blower with 450-500 CFM and 150-190 MPH ratings.
Airspeed and Force
Remember that a leaf blower's advertised airspeed and voltage are its best-case scenario at full power and, sometimes, using specific nozzles. For the most potent and efficient blower you can find, we recommend the Cat 60-volt, 800-CFM leaf blower.
What is different between them: - Weight: 20v is amazingly light (especially when using a 2Ah battery). With 2x 4Ah nitro batteries the 40v is significantly heavier. The blowers themselves are same weight, it's all in the batteries.
ft.): Look for a blower in the range of 200-400 CFM to handle a moderate amount of leaves and debris effectively.
