Cordless Leaf Blower Ratings: What CFM, MPH and Blowing Force Actually Tell You

Mid-October is when a blower stops being a tidy-up tool and becomes the only way to move a week of wet leaves off a driveway. Most listings lead with a number: 400 CFM, 600 CFM, 145 MPH, 239 MPH, 41 newtons. Those are not the same measurement, they are not taken at the same point in the tube, and in October 2026 the three maker pages we opened did not publish the same ones.

We have not tested any blower and will not claim to. What follows compares what manufacturers publish on their own US pages, what the federal engine rules cover, and what the Consumer Product Safety Commission recall database records. Our selection rule: widely sold blower lines whose maker publishes a spec on a public page we could open, each checked against the CPSC recall database on October 12, 2026.

Cordless is the default and the spec sheets no longer line up

Three major makers publish different headline numbers for the same job: 600 CFM, 145 MPH and 17.7 newtons on one 18V blower page, 239 MPH and 41 newtons on a backpack page with no airflow figure, and 765 CFM with no air-speed figure on a third. None of the three pages states its test conditions.

Our editorial reading of the cited data, not a forecast. How it is scored

CFM and MPH are two different promises

Cubic feet per minute describes how much air the machine moves. Miles per hour describes how fast that air moves as it leaves the opening. A narrow nozzle raises the speed and lowers the volume; a wide tube does the reverse. That is why a backpack can publish a very high air speed with a round nozzle fitted while a handheld publishes a high CFM with a flat one, and why neither figure alone says which clears a wet lawn faster.

A third figure now appears instead of either: blowing force in newtons, which folds the two into one thrust measurement. STIHL lists 41 N with the round nozzle on its BR 800 X Magnum page, and Husqvarna lists blow force in newtons for almost every blower on its US range page while giving an airflow figure for only one. None of the pages we read stated a test condition, and airflow measured at the fan housing is larger than airflow measured at the end of a fitted tube.

Compare CFM within one brand; across brands, newtons of blowing force is least likely to be mixing methods.

Three spec sheets, three different numbers

The table below is what each maker printed on its own page on October 12, 2026. We added nothing and converted nothing, and the gaps are the point: a shopper comparing two listings will often find the figure given for one is absent for the other.

Sound is where this gets thinnest. Milwaukee gives a decibel rating in its specification list and again inside a graphic comparing the tool with a gas competitor, but neither states a measurement distance. Local blower rules work in decibels at a stated distance, so we are not repeating a figure that cannot be checked against an ordinance.

Maker and model	Airflow published	Air speed published	Other figures on the page
Milwaukee M18 FUEL dual-battery blower 2824-20	600 CFM	145 MPH	17.7 N, 6.01 lb, decibel rating without a distance
STIHL BR 800 X Magnum backpack	Not listed on the product page	239 MPH with round nozzle	41 N blowing force, 25.9 lb, 4.9 cu in displacement
Husqvarna 150BT backpack	765 CFM, in the description	Not listed	22 N maximum blow force

What the recall record says about blower fans

We pulled the CPSC recall database for blowers on October 12, 2026 and counted the entries ourselves. Setting snow blowers and air movers aside, 40 notices remain, and by title they split between two hazards: 17 for fire or burns and 14 for laceration, impact or projectile. The laceration group keeps returning to one component, the fan or the fan wheel breaking apart inside the housing. The most recent is STIHL’s recall of the BR 800 X Magnum and C-E Magnum backpack blowers, announced November 6, 2025 and covering about 47,800 units sold from May 2025 through September 2025. The notice reads: the fan wheel inside the backpack blower can break apart, posing a laceration hazard. No injuries were reported; the remedy is a free dealer fan wheel replacement.

Two older notices show the same pattern at scale. DR Power recalled about 57,200 walk-behind leaf blowers and vacuums on May 2, 2024 after 22 reports of loose pieces being ejected. In March 2017, One World Technologies recalled about 121,000 Ryobi 8-amp electric jet fan blowers after 10,681 incident reports and 25 reports of minor injuries. One is a premium backpack, one a wheeled machine, one a $40 corded unit, so the failure is not confined to a price bracket. A recall notice records which products were found to fail, not which ones will not.

The battery is the other half of the purchase

One of the ten Amazon completions is leaf blower cordless with battery and charger: a bare tool and a kit are different purchases, and the pack is usually the larger cost. Check the amp-hours of the included pack, whether a charger is in the box, and whether the voltage matches tools you own.

The battery is also where the largest recent recall sits. On July 9, 2026 Greenworks Tools recalled about 554,780 Kobalt 24V and 48V yard power tools sold at Lowe’s and Lowes.com from January 2026 through May 2026, including blowers rated 270 CFM/100 MPH and 600 CFM/150 MPH. The notice reads: charging the lithium-ion batteries through the USB-C port, while the batteries are inserted in the yard power tools can cause the batteries to short-circuit, posing a risk of serious injury from fire hazard. CPSC recorded 34 reports of smoke, sparking or fire, with no injuries reported.

• Amp-hours of the pack actually in the box, not the largest pack the tool accepts
• Whether a charger ships with the kit, and how long a full charge takes
• The model number against the CPSC recall database before checkout
• Any instruction about charging a pack while it is seated in the tool

Which type fits which yard

Federal rules are why this category went cordless at all. 40 CFR part 1054 applies its exhaust requirements to new nonroad spark-ignition engines with maximum engine power at or below 19 kW, the band every handheld yard engine sits in, and EPA’s small-equipment page says the Phase 3 exhaust standards took effect in 2011 or 2012 depending on engine size. Those rules govern the engine; local ordinances govern the use, which we covered in our report on gas leaf blower bans and the battery shift.

For a deck, a patio and a short driveway, a handheld unit on a platform you already own is the straightforward choice, and the mini and small completions suggest that is what most people want. For a lot with mature trees and a heavy October drop, a backpack moves more air for longer and carries the weight on your back. A spare pack changes the job most, since runtime ends most sessions. Our pieces on wire-free robot mowers and garden tool prices cover the same platform decision.

What to watch next

• Whether any maker starts publishing the test condition next to its CFM figure
• New CPSC entries for blower fan or fan wheel failures, which appeared in 2017, 2024 and 2025
• Whether USB-C charging returns to tool batteries after the July 2026 Kobalt recall

Questions readers ask

Is CFM or MPH more important on a leaf blower?

They measure different things: CFM is the volume of air moved per minute and MPH is the speed the air leaves the tube, usually with a specific nozzle fitted. None of the three maker pages we read on October 12, 2026 stated where the figure was measured, so compare airflow within one brand and use newtons of blowing force when a maker publishes it.

Have cordless leaf blowers been recalled?

Yes. On July 9, 2026 Greenworks Tools recalled about 554,780 Kobalt 24V and 48V yard power tools, blowers among them, because charging the lithium-ion batteries through the USB-C port while they sat in the tool could short-circuit them. CPSC recorded 34 reports of smoke, sparking or fire, with no injuries reported.

Why do blower recalls keep mentioning the fan?

It is the component behind the laceration notices. CPSC notices include a November 6, 2025 STIHL recall of about 47,800 BR 800 backpack blowers whose fan wheel can break apart, a May 2, 2024 DR Power recall of about 57,200 units after 22 reports of ejected pieces, and a March 2, 2017 recall of about 121,000 Ryobi electric blowers after 10,681 incident reports.

What rule covers the engine in a gas leaf blower?

40 CFR part 1054. Its exhaust requirements apply to new nonroad spark-ignition engines with maximum engine power at or below 19 kW, and the handheld Phase 3 standards in section 1054.103 are 50 grams per kilowatt-hour of hydrocarbons plus nitrogen oxides for Class III and Class IV engines.
