40v vs 56v leaf blower: the short answer

Voltage class alone does not settle the choice. Compare the stated airflow, the stated runtime, the stated weight and whether a battery and charger come in the box, because those four points differ more between these listings than the voltage badge does. Airflow here does not follow voltage: the 20V YOOVL lists 650 CFM, above both 40V listings, so a lower voltage listing can still suit a regular cleanup routine.

On the listings in this guide, the 56V EGO blower lists the strongest peak airflow at 670 CFM with air speeds up to 180 MPH, plus up to 80 minutes of runtime on its included 4.0Ah battery. The 40V WORX blower lists 530 CFM and 180 MPH with a stated 57 dB sound level, but its listing states that battery and charger are not included. The 40V Heywork blower lists 600 CFM and 160 MPH and adds vacuum and mulching functions with two included 4.0Ah batteries. The YOOVL blower lists 650 CFM, but it runs on 20V batteries, so it sits outside both classes in the question.

Compare the four blowers

Blower	Stated airflow	Note
EGO POWER+ 56V LB6703	670 CFM, 180 MPH	Battery and charger included; 5-year tool warranty and 3-year battery warranty stated
WORX 40V WG581.9	530 CFM, 180 MPH	Battery and charger not included; 57 dB stated
Heywork 40V	600 CFM, 160 MPH	Blows, vacuums and mulches; 40L bag stated
YOOVL 20V	650 CFM	Two 20V 5.2Ah batteries and charger included; sits below both voltage classes

The gear in this guide

EGO POWER+ 56V LB6703 leads this set on stated peak airflow. The listing states up to 670 CFM in turbo mode with air speeds up to 180 MPH, and a variable speed dial with a lock that covers 250 to 530 CFM for lighter work. Runtime is stated as up to 80 minutes on the included 4.0Ah battery, and the included charger is stated to charge that battery in 55 minutes. The spec table lists 11.68 pounds. The listing also states a 5-year tool warranty and a 3-year battery warranty, and states that the blower works with all EGO 56V ARC Lithium batteries. For deep, wet piles, that turbo figure is the listing’s stated answer for the job.

Heywork 40V comes next as a versatile pick in the set, because it combines blowing, vacuuming and mulching in a 3-in-1 cordless tool. The listing states 600 CFM and 160 MPH with the included two 4.0Ah batteries, plus 4 speed settings and Turbo Boost for heavier leaves and debris. The mulching ratio is stated as 15:1, turning 15 bags of leaves into one, and the stated bag holds 40L. The spec table lists 10.0 pounds. Where leaves need collecting rather than just moving, the vacuum and mulching functions give this blower a job the other three do not claim.

WORX 40V WG581.9 suits regular cleanup where the stated 57 dB sound level and the 7.7 lb stated weight matter. The listing states up to 530 CFM and up to 180 MPH, with 3-speed control plus Turbo for wet leaves, compacted grass and heavier yard debris, and a stated 57 dB sound level. Dual tubes let the user pick the larger tube for higher air volume or the smaller tube for higher air speed. One contradiction needs noting: the bullets state 7.7 lbs with battery, while the spec table lists 4.19 pounds, so this guide follows the bullets and uses 7.7 lbs. The listing states that battery and charger are not included, so a buyer without a WORX PowerShare battery needs to add them. PowerShare is stated to combine 20V batteries to power WORX tools at 20V, 40V or 80V.

YOOVL 20V closes the set as a lower-voltage contrast. The listing states up to 650 CFM with 3 speed modes, two 20V 5.2Ah batteries, a fast charger, a blower tube, an extension nozzle and an adjustable shoulder strap, with up to 150 minutes stated for the two-battery setup. The bullets print the airflow figure as 650CMF, a misprint of the title’s 650 CFM, so this guide uses 650 CFM. No weight is stated for this blower. It does not answer the 40V or 56V side of the question directly, but it shows what a 20V dual-battery kit offers for light snow, dust, grass clippings and dry leaves on lawns, sidewalks and garages.

Voltage, airflow and runtime: what actually differs

Airflow in CFM describes how much air the blower moves, while MPH describes how fast that air travels. A high CFM figure suits wide, open areas and deep piles, while a high MPH figure suits stuck-on debris on hard surfaces. The listings here pair those figures differently: EGO and WORX both state 180 MPH, but EGO states 670 CFM against 530 CFM for WORX, while Heywork states 600 CFM at 160 MPH. Matching the pair to the surface matters more than matching the voltage badge.

Runtime depends on the battery in the box and the speed setting chosen. EGO states up to 80 minutes on a 4.0Ah battery, YOOVL states up to 150 minutes across its two 5.2Ah batteries, and Heywork includes two 4.0Ah batteries without stating a runtime figure. WORX states no runtime figure and no battery in the box, so runtime there depends on the battery the buyer adds.

Platform matters for buyers who already own cordless tools. EGO states compatibility with all EGO 56V ARC Lithium batteries, and WORX states PowerShare across 20V, 40V and 80V tools. A buyer already on one of those platforms gets more value from the matching blower, since the battery can serve other tools in the same system.

Safety

Wear eye and hearing protection and sturdy shoes. Clear sticks, stones and other debris before blowing, and keep children, pets and bystanders away from the work area. Point blower nozzles away from people and parked cars, and never blow leaves toward a pond, ditch or road.

FAQ: mowing large lots

Is a 56V leaf blower always stronger than a 40V leaf blower?

Not by voltage alone. Compare the stated CFM and MPH: the 56V EGO lists 670 CFM, while the 40V Heywork lists 600 CFM and the 40V WORX lists 530 CFM, so the 56V listing leads here, but the gap comes from the stated airflow figures rather than the voltage number itself.

Can a 40V leaf blower clear wet leaves?

WORX lists Turbo for wet leaves, compacted grass and heavier yard debris, and Heywork lists Turbo Boost for heavier leaves and debris. For wet piles, use the Turbo setting the listing describes.

Do I need to buy a battery and charger separately?

It depends on the listing. WORX states that battery and charger are not included with the WG581.9. EGO includes a 4.0Ah battery and charger, Heywork includes two 4.0Ah batteries, and YOOVL includes two 20V 5.2Ah batteries and a fast charger.

What does the Heywork mulching ratio mean?

The listing states a 15:1 mulching ratio, turning 15 bags of leaves into one, with a 40L bag for collecting the mulched material. That suits buyers who want to collect leaves rather than blow them into a pile for later handling.

Which blower in this guide lists a sound level?

Only WORX states a sound level, at 57 dB. No sound level is stated for the EGO, Heywork or YOOVL listings, so no quiet claim can be made for those three from the listings alone.
