The Black+Decker LSWV36's performance versus other blowers
The following charts are provided to give you an idea how the key specs of the Black+Decker LSWV36 compare with handheld leaf blowers of similar voltage (between 36 and 48V).
- Upon exiting the nozzle, the air can reach speeds of up to 120 MPH, which is on the lower end for battery-operated handheld blowers between 36 and 48V. For the fastest air speed in this category, you may want to consider the Husqvarna 350iB, which can expell air at a velocity that can reach 200 MPH.
- With a maximum airflow of 90 CFM (cubic feet per minute), this model is on the lower end in terms of air circulation for cordless handheld blowers. For the highest air volume, you may want to have a look at the Husqvarna 350iB, which boasts with 800 CFM.
- With a runtime of up to 30 minutes on a full charge, the LSWV36's autonomy is modest compared to other cordless handheld units. To enjoy the best possible autonomy in this category, you could have a look at the Makita CBU01Z which offers up to 300 minutes of runtime.

POWERBOOST Technology

POWERBOOST is one of the features of the POWERCOMMAND™ line of Black+Decker outdoor power tools. The Black+Decker LSWV36 has a button that gives it a surge in blowing speed when pressed. Although POWERBOOST uses a lot of power (which drains the battery faster) , it is quite useful for loosening up those stubborn patches of debris that get stuck and otherwise refuse to budge. When POWERBOOST is used sparingly, the LSWV36 enjoys a normal runtime, so this feature is definitely ideal for tackling less rigorous tasks with more precise control.

- Leaf collection bag included
- POWERBOOST Technology
