Factors to consider with leaf blowers

  • Sound level
    Some units can get quite loud, and even though electric units are quieter than their gas-predecessors, most still require hearing protection for long-term use.
  • CFM, mph
    Short for cubic feet per minute and miles per hour, respectively, most manufacturers use these metrics to convey the overall strength and power of their leaf blowers. While not an exact comparison, it’s a good place to start as you’re shopping between models.
  • Brand
    Most of the manufacturers in the outdoor tool space also offer other outdoor/indoor tools that can all run off of the same battery. That means it’s worth checking to see if your leaf blower’s battery could swap in as a power source for any of the tools you already own, or any that you plan to purchase later.
  • Battery voltage
    Even within a single brand, there are often multiple battery voltage platforms. Check to see if what you’re buying will work with the tools you already have.

How we test leaf blowers

We test lots of things here at the Louisville-based CNET Test Lab. Some tests are easy, some are more difficult. Some take a few minutes and some take days. Creating test protocols for new product categories is always exciting, but let me tell you that anytime the phrase “air cannon” comes up in our proposed test methodologies, there’s a bit of extra electricity in the air.

We’ll get to the air cannon results in a bit, but we start our tests by actually using the leaf blowers as intended. We hold them, we push the buttons, we blow stuff around — you know, leaf blower-y stuff. As we go, we make sure to evaluate the balance and ergonomics of the overall design, including attachments. A product that performs well but is difficult to use — or one that’s literally painful to your person — well, that isn’t likely to score well.

Electric leaf blower noise levels

A bar graph highlights the operating volume, in decibels, of six leaf blowers. None of them are quiet, but the Ryobi 40V model rings in at 81.5 decibels, while the other five models from Craftsman, Ego, Greenworks Pro, Milwaukee, and Dewalt all measured in between 93 and 97 decibels.

We do love our data, so we make sure to collect and analyze manufacturer specs alongside our own test data. There are two main points of data that we collect for leaf blowers: The first is sound level. As a contributor to restrictions being placed on outdoor tools across the country, excessive noise can be quite the bother. That’s why we run a sound level test for each model, placing it at approximately the distance you might expect to find this type of product operating from your ear. We position it perpendicular to the sound level meter and record the results. You can see those results in the graph above, where it’s clear that Ryobi’s blower is, by far, the quietest of all the units we tested. Everything else sits in a cluster as they race for loudest leaf blower — a title currently held by the DeWalt Max Flexvolt 3. 

This is where our propulsion cannon comes in. Yes, we could have grabbed some leaves and some loose debris and blown it around our test spaces, and said, “Hey, this thing blows leaves.” But we wanted to go one step further and see how the leaf blowers’ output translated to raw power. 

A custom-built air cannon made from PVC pipe sits atop a wooden frame. It's shaped like a big checkmark. We stick a leaf blower's nozzle into the bottom end and rev it up, then pull a handle to open a valve, which lets all of that air power propel a weight out of the top.

To do this, we built an air cannon mostly from 3-inch PVC. Amenities included are an air gate, so we can ramp up each unit and release all the air into the cannon instantly, and a restriction plate, to keep the projectile from entering the core of the apparatus. There’s also a base for balancing and a 5-foot barrel for launching the projectile. 

The projectile itself is a round plastic tube (similar to those pneumatic-driven tube containers at bank drive-throughs) containing a sand mixture and, in total, weighs 210 grams.

A visualization shows the maximum average distance that each of six electric leaf blowers were able to shoot a 210g weight when used to power a custom-built air cannon. The top distance goes to the 80V Greenworks Pro leaf blower, which blasted that weight well over thirty feet.

Here’s Eric from our lab demonstrating the air cannon in action. Each colored line represents the longest average distance achieved by each model — of all of them, the Greenworks Pro leaf blower shot our weight the farthest. All of those high scores were achieved in the respective blower’s turbo mode, except for the DeWalt leaf blower, which only has a single setting.

We load the projectile into the cannon, secure the leaf blower nozzle into the input port, ramp the leaf blower up to full strength in the selected mode, open the air gate and foomp. We measure the distance the projectile travels from its resting location within the cannon to the spot of initial impact on the floor. We average this distance over multiple attempts. Voila!

We tested each leaf blower at both normal and turbo settings, noting that the DeWalt Max Flexvolt 3 only offers a single setting. The colorful visualization above shows the maximum average distance achieved by each brand, and makes it clear that our top pick from Greenworks blew the competition away as far as air power is concerned. You can find the full results from both rounds of tests in the graph below.

A double bar graph shows the distance, in feet, that each of the six leaf blowers we tested shot a 210g weight through a custom-built air cannon, both in each blower's normal mode and, if it offered one, its turbo mode as well. The Greenworks Pro 80v model was the clear winner here, shooting our weight more than 35 feet in turbo mode. No other leaf blower, turbo mode or otherwise, was able to shoot farther than 28 feet.

Some takeaways here. First, the DeWalt model doesn’t offer two separate modes. If we count that as not having a turbo mode, technically it would win the normal mode comparison. But since it can’t go any higher in terms of power, it’s already kind of in turbo mode. It’s simultaneously in and out of both normal and turbo states — a Schrödinger’s leaf blower if you will. Otherwise, Greenworks was the big winner. On the opposite end of the scale we have the Milwaukee model, which was barely able to get the weight out of the barrel of our cannon at all.

The test results are interesting here when you start comparing specs. Take the Milwaukee and Craftsman blowers, for instance. The advertised specs for CFM and mph are nearly the same — 120 and 450 for Milwaukee and slightly lower numbers of 110 and 410 for Craftsman. However our test data shows Craftsman outperforming Milwaukee more than 12 feet in normal mode, and outperforming it by more than 10 feet in turbo mode.

Other leaf blowers we’ve tested

Milwaukee M18 Fuel Model 2724-40: This unit was probably the most disappointing one to test. Its specs lined up with a couple of the other smaller units on our list, but the overall performance was drastically different. In our propulsion tests, the Milwaukee was barely able to dribble the projectile out of the launch tube at its normal setting, giving it a score of about 5 feet. Turbo mode kicked that up to 14.5 feet, but that was still dead last in our turbo tests, and less distance than we saw from three of the other leaf blowers in normal mode. Meanwhile, our top power pick from Greenworks was almost five times as powerful as Milwaukee’s blower in normal mode and more than twice as powerful in turbo mode — and it costs $100 less!

Ego 56V Leaf Blower Model LB7654: Ego did come in second overall in our propulsion tests, so give it some credit. That tracks, as we’ve generally seen high performance scores from Ego across the brand when it comes to power. Still, at the end of the day, Greenworks edged it out in our lab and took the top spot on this list. It’s still a solid choice with a good price point — especially if you own other Ego products that can borrow its battery when needed.

DeWalt 60V Model DCBL772X1: This model was the only one on our list that doesn’t offer two separate modes (normal, turbo). That seems a bit odd when you consider that the interior chamber of this thing actually looks like a jet turbine engine. It had better-than-average performance from its one mode, but the price seemed a bit too high at $300. It was also worth noting that this unit took an extra three seconds (give or take) to spool up to full power. Not really a game changer, but good to know if you tend to use short bursts.

Leaf blower FAQs

How strong of a leaf blower do I need?

As with most product categories, the answer depends partially on your intended use. Do you have a small yard with light occasional debris? Or do you have a large yard with many deciduous trees or lots of other debris?

Are electric leaf blowers worth it?

Not only are electric leaf blowers worth it (especially the cordless variety), but soon, you may find that these are, in fact, your only options.

What voltage is best for a leaf blower?

The answer really is, “It depends,” but let me give you a little context for that.
