Choosing between a 40V vs 24V leaf blower depends on your yard size and debris type. Both tools use brushless motors for efficiency and durability. The main difference lies in power output and functionality. The 40V model offers higher air speed and volume, plus vacuum capabilities. The 24V option provides longer runtime on low settings and quieter operation. You should pick based on whether you need raw power or extended, quiet cleanup time.

40V vs 24V Blower Specs
Air Volume Output
The MZK 40V model delivers 700 CFM of air volume, significantly outperforming the Greenworks 24V blower, which provides 515 CFM. Higher cubic feet per minute means you can move larger piles of dry leaves and light debris faster. If your yard has thick layers of fallen foliage, the MZK’s superior airflow will clear paths more efficiently. The Greenworks unit handles standard cleanup tasks well, but the MZK offers a noticeable advantage in raw moving power for heavier loads.
Air Speed Performance
Wind speed determines how well you can dislodge wet, stuck debris. The MZK 40V reaches 180 MPH, while the Greenworks 24V tops out at 130 MPH. That 50 MPH difference allows the MZK to blast wet leaves off patios and driveways with greater force. The Greenworks brushless motor is efficient, but its lower max speed may struggle with damp, matted leaves. For stubborn, wet debris, the higher velocity of the MZK provides a clear practical edge.
Runtime Capacity
Battery runtime varies by usage mode. The Greenworks 24V offers up to 40 minutes on low speed and 20 minutes on high, thanks to its 5.0 Ah battery. The MZK 40V provides 30 minutes of continuous runtime using its 4.0 Ah batteries. If you prefer longer, slower cleaning sessions, the Greenworks lasts longer. However, if you need sustained high-power output, the MZK’s runtime is competitive. The Greenworks holds the edge for low-speed endurance.
Functional Versatility
Functionality differs greatly between these tools. The MZK 40V is a 3-in-1 device that blows, vacuums, and mulches with a 15:1 mulching ratio. It includes a 40L bag and wheels for easy transport. The Greenworks 24V is a blower only, with no vacuum or mulching capabilities. If you want to collect leaves into bags or reduce their volume for disposal, the MZK is the only viable option. The Greenworks is strictly for blowing debris to the side.
Weight and Portability
Weight affects user fatigue during extended use. The MZK 40V weighs 10 pounds, while the Greenworks 24V weighs approximately 10.9 pounds (based on model BL24515 with battery). Both are relatively lightweight for cordless tools. The MZK includes wheels to support its weight, reducing the load on your arms. The Greenworks relies on a handheld design with cruise control to reduce hand strain. The MZK’s wheeled design offers a slight advantage in reducing physical effort.
Which Cordless Leaf Blower Fits Your Needs
Users needing vacuum and mulch functions
The MZK 40V model offers three functions: blowing, vacuuming, and mulching. Its 700 CFM air volume and 180 MPH air speed handle heavy debris efficiently. The 40-liter bag and 15-to-1 mulching ratio reduce emptying frequency. This versatility makes it ideal for yards with varied waste types.
Buyers wanting longer runtime on low settings
The Greenworks 24V blower provides up to 40 minutes of runtime on low speed. Its 515 CFM air volume is sufficient for lighter tasks. The 5.0 Ah battery charges quickly via USB Type-C. Cruise control helps reduce hand fatigue during extended use, making it practical for smaller areas.
Those prioritizing maximum air speed and volume
With 700 CFM and 180 MPH, this 40V blower moves more air than the 24V competitor. The brushless motor supports a turbo mode for wet debris. The anti-jam design and adjustable speeds ensure consistent performance. This power output is best for clearing large piles or dense yard waste quickly.
Users valuing quiet operation and warranty
The Greenworks 24V blower operates at 61 dB, which is quieter than many competitors. It includes a three-year warranty for peace of mind. The soft round nozzle allows for controlled airflow. These features suit users who prioritize noise reduction and long-term support over maximum blowing power.
