Verdict: Choose a 40v leaf blower if the work is patios, driveways and lawns and a lighter tool matters, or vacuum and mulching options matter. Choose an 80v leaf blower if the work is larger areas and heavier debris and the higher stated airflow matters, and the battery platform is already on the bench.
A driveway covered in wet leaves after a storm, a lawn scattered with dry leaves and a patio that needs clearing before guests arrive all ask the same question, and the 40v vs 80v leaf blower choice comes down to how much air is needed and how much weight is acceptable to carry. This comparison uses four battery blowers as concrete examples, two from each side, and builds the verdict around what separates them.

Read the full review
The listing states up to 530 CFM and up to 180 MPH, a brushless motor, 3-speed control with Turbo for wet leaves, a dual-tube design for volume or speed, a 57 dB noise level and a weight of 7.7 lbs with battery. The PowerShare note says 20V batteries combine to power 20V, 40V or 80V tools. The title and bullets agree on the airflow figures, and the spec table confirms the 7.7 lb weight, so there is no contradiction to work around.
Pros
- Lightest stated weight at 7.7 lbs with battery
- Lowest stated noise level at 57 dB
- 3-speed control with Turbo for wet leaves

Greenworks 80V 770-CFM 180-MPH Cordless Leaf Blower, Bare Tool
An 80v axial blower stating 770 CFM and 180 MPH, with a brushless motor and cruise control, sold as a bare tool.
Who it's for: owners already on the Greenworks 80V platform who want high stated airflow.
Who should skip it: anyone buying a first battery tool, since battery and charger are not included.
Read the full review
The listing states 770 CFM and 180 MPH, a brushless motor, trigger-activated variable speed control with cruise control, QUIETFORCE technology, a concentrator nozzle and a weight of less than 10.56 lbs with battery. It contradicts itself on the gas equivalent, stating a 27cc gas engine equivalent in one bullet and the equivalent power of a 28cc engine in another, so the review trusts neither figure over the other. The listing also states clearly that battery and charger are not included.
Pros
- High stated airflow at 770 CFM and 180 MPH
- Brushless motor with quieter operation stated at 74 dB
- Trigger-activated variable speed control and cruise control
- Concentrator nozzle increases air speed for stubborn debris
Cons
- Battery and charger not included; bare tool only
- No warranty term stated in the listing
- Listing states both 27cc and 28cc gas equivalents
- Heavier than the WORX example at 7.7 lbs

40v vs 80v leaf blower side by side
| Factor | WORX WG581.1 (40v) | YDblac 3-in-1 (40v) | Greenworks 770 (80v) | Greenworks 800 backpack (80v) |
|---|---|---|---|---|
| Airflow | 530 CFM | 600 CFM | 770 CFM | 800 CFM |
| Air speed | 180 MPH | 160 MPH | 180 MPH | 195 MPH |
| Weight | 7.7 lbs with battery | Not stated | Less than 10.56 lbs with battery | 11.02 pounds |
| Battery and charger | 2 batteries and dual charger included | Two 4.0Ah batteries included | Battery and charger not included | 4.0Ah battery and rapid charger included |
| Special function | Dual-tube air control | Blowing, vacuuming and mulching | Concentrator nozzle | Backpack carry with leaf tarp |
Figures are manufacturer stated for the four example models, collected 30 October 2026.
Airflow: CFM and MPH
On these four listings, the 80v examples state the higher airflow figures: the Greenworks 800 backpack example states up to 800 CFM with air speeds of 195 MPH, and the Greenworks 770 example states 770 CFM and 180 MPH. The 40v examples state lower figures: the YDblac example states up to 600 CFM and 160 MPH, and the WORX example states up to 530 CFM and up to 180 MPH. Air speed tells a different story from volume alone, since the WORX example matches the Greenworks 770 example at 180 MPH despite its lower CFM. A figure from one listing describes that listing only, so the comparison holds only where both sides state the same spec.
Battery, weight and what comes in the box
Battery inclusion splits the four examples more sharply than voltage does. The WORX example includes 2 batteries and a dual charger, the YDblac example includes two 4.0Ah batteries, and the Greenworks 800 backpack example comes with a 4.0Ah battery and rapid charger. The Greenworks 770 example is a bare tool only, with battery and charger not included, so it suits an owner who already owns the platform battery. Weight follows a similar split: the WORX example is 7.7 lbs with battery, the Greenworks 770 example is listed at less than 10.56 lbs with battery, and the Greenworks 800 backpack example is listed at 11.02 pounds. The YDblac example states no weight, so the listing leaves that figure unclear rather than losing on it.
Jobs each side handles
The 40v side covers more job types on these listings. The YDblac example combines blowing, vacuuming and mulching in one tool, with a 40L collection bag and a 15:1 mulching ratio, while the WORX example offers 3-speed control with a Turbo setting for wet leaves and a dual-tube design that swaps volume for speed. The 80v side leans on raw airflow: the Greenworks 770 example adds a concentrator nozzle for stubborn debris, and the Greenworks 800 backpack example adds cruise control, a turbo button and a leaf tarp for larger clearing jobs. On noise, only two listings state a figure: the WORX example at 57 dB and the Greenworks 770 example at 74 dB, so the 40v example is quieter on stated figures, while the other two listings state no noise figure.
The four examples
Acreage and terrain fit
Matching It to Your Property
- Patios, driveways and small lawns: the 40v examples fit flat, obstacle-filled ground near the house.
- Larger lawns and heavier debris: the 80v examples fit open, rough ground where higher stated airflow clears faster.
- Storage and battery platform: the bare-tool 80v example needs a platform battery already owned, while the other three examples include batteries in the box.
- Vacuum and mulching work: only the YDblac example among the four states blowing, vacuuming and mulching in one tool.
Wear eye and hearing protection, long pants and sturdy footwear, and keep bystanders well back while the line or blade spins. Clear stones and debris first, and stop the engine or remove the battery before clearing the head. Refuel only with the engine off and cool. See OSHA landscaping safety. Read our Safety Disclaimer.
The Acre Score explained
The Acre Score weighs five factors: performance (airflow and air speed), build quality (motor type and handling), value (what comes in the box), safety (operator controls the listing states) and warranty (years and coverage). A factor the listing does not state scores zero, which is why three examples score zero for warranty while the Greenworks 800 backpack example scores for its stated 4-year warranty. For more single-tool options, see leaf blower picks.
| Product | Acre Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| Greenworks 800 | 9.7 | 32 | 21 | 21 | 7 | 3 |
| YDblac 3-in-1 | 9.6 | 30 | 20 | 21 | 5 | 0 |
| WORX WG581.1 | 9.6 | 29 | 21 | 20 | 5 | 0 |
| Greenworks 770 | 9.5 | 30 | 20 | 16 | 6 | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
FAQ: mowing large lots
Does higher voltage always mean more airflow?
On these four listings, the 80v examples state higher CFM figures than the 40v examples, but voltage alone does not settle it: the WORX 40v example matches the Greenworks 770 80v example at 180 MPH, and only the YDblac 40v example adds vacuuming and mulching.
Can a 40v blower handle wet leaves?
The listings say yes for both 40v examples: the WORX example offers a Turbo setting for wet leaves, and the YDblac example offers Turbo Boost for wet debris.
Does the 80v bare tool include a battery?
No. The Greenworks 770 example states that battery and charger are not included. The Greenworks 800 backpack example, by contrast, comes with a 4.0Ah battery and rapid charger.
Which example is the lightest?
Among the examples that state a weight, the WORX example, at 7.7 lbs with battery. The Greenworks 770 example is listed at less than 10.56 lbs with battery, and the Greenworks 800 backpack example is listed at 11.02 pounds. The YDblac example states no weight.
What safety gear suits a leaf blower?
Eye protection and hearing protection, with debris cleared from the work area before blowing. Keep people and pets well back, since blowers throw debris at speed.
