Black+decker powercommand 40v max review: the short verdict
The PowerCommand 40V MAX LSW36 is BLACK+DECKER’s cordless yard sweeper: a 40-volt Li-ion blower rated at 90 CFM with variable speed up to 120 MPH. The kit includes the blow tube, an LBX1540 40V MAX battery, an LCS36 fast charger and a state-of-charge indicator on the battery. The blow tube has a built-in scraper for matted leaves and stuck-on debris, and the soft grip handle adds comfort. The listing states a 3-year warranty.
The trade-offs are the airflow ceiling and the weight figure: 90 CFM suits hard surfaces and light debris, and the listing states 4.7 pounds in the bullets against 3.1 pounds in the spec table.

The pick in the lineup
Below is our card for the LSW36, with the Acre Score it earned.
What the PowerCommand 40V MAX does well
90 CFM with speed control
A 90 CFM rating with variable speed up to 120 MPH covers the yard-sweeper job: clearing leaves and debris from hard surfaces. The POWERCOMMAND control adjusts speed for maximum run-time or maximum power, so you can dial down for light dusting and up for stuck-on debris.
Battery kit with fast charging
The 40V MAX Li-ion battery is described as high performance for long runtime, and the fast charger recharges it in 90 minutes or less. A state-of-charge indicator shows the battery level before you start.
Debris extras
The blow tube has a built-in scraper that loosens matted leaves and stuck-on debris, a detail the listing calls out for exactly the messes blowers leave behind. The soft grip handle adds comfort during use, and the low-noise design is stated at 66 dB.
Stated warranty
The listing states a 3-year warranty. A stated warranty term earns warranty points in our Acre Score; many competing listings state none.
Limitations to know before you buy
Weight contradiction
The bullets state 4.7 pounds; the spec table states 3.1 pounds. One of the 2 is wrong, so expect the heavier figure when you plan.
90 CFM is a sweeper, not a storm tool
At 90 CFM, this is a yard sweeper for hard surfaces and light debris, per the listing’s own style name: 40V Sweeper Kit. Deep leaf piles and wet mats are beyond its stated class.
No runtime figure
The listing promises long runtime but states no minutes. The POWERCOMMAND speed control manages it, but the actual minutes are not stated.
66 dB is stated low, not silent
The listing calls the design low noise and states 66 dB. That is a stated figure, not a guarantee about your neighbors.
Who should skip the PowerCommand 40V MAX
- Owners of big yards with deep leaf fall; 90 CFM is a sweeper rating.
- Anyone who needs a stated runtime; the listing gives none.
- Users who want a vacuum or mulching function; this is a blower only.

What 90 CFM and 120 MPH mean in practice
Two numbers describe a blower: CFM moves the pile, MPH moves the stubborn bits. The LSW36 lists 90 CFM of airflow with speeds up to 120 MPH. 90 CFM is a sweeper rating: it clears driveways, decks and garages of loose leaves and dust, which is exactly what the listing promises. 120 MPH is the top-end airspeed for stuck-on debris. The variable speed control is the bridge between them: dial down for light dusting without scattering mulch, dial up for matted leaves. The listing positions it as a hard-surface and yard sweeper, and the numbers agree: it is a sweeper first, a blower second.
Battery and charging: the 40V system
The LSW36 runs on a 40V MAX lithium ion battery, the LBX1540, with a state of charge indicator that shows the remaining level. The included LCS36 fast charger recharges the battery in 90 minutes or less, per the listing. The POWERCOMMAND speed control manages the trade between runtime and power: low speed stretches the battery, high speed spends it. The listing promises long runtime but states no minutes, so treat the 90-minute recharge as the hard number and the runtime as use-dependent. One battery in the kit means no hot-swap mid-job; a second 40V battery would be the upgrade for bigger yards.
Comfort and handling: weight, noise and grip
The listing states two weights: 4.7 pounds in the bullets and 3.1 pounds in the spec table. Either figure is light for a handheld blower, and the soft grip handle adds comfort during use. The low noise design is stated at 66 dB: quieter than gas blowers, but not silent, so early-morning use near neighbors still needs judgment. The blow tube has a built-in scraper for loosening matted leaves and stuck-on debris without bending over. At 14.63 by 10.63 by 6.31 inches, it stores on a shelf. Light, quiet-ish and compact is the right recipe for quick driveway and deck sessions.
Sweeper vs blower: where the LSW36 fits
The listing calls the LSW36 both a sweeper and a blower, and the distinction matters. As a sweeper, it clears hard surfaces: driveways, decks, garages, patios. As a blower, 90 CFM handles light yard leaves but not deep leaf fall or wet piles. It is not a vacuum and it does not mulch; the listing describes a sweeper and blower only. Buy it for the hard-surface job it names, not for the leaf-season job it does not.
The 3-year warranty and what it covers
The listing states a 3-year warranty, which is a solid term for a cordless handheld tool. It covers manufacturing defects; wear items like the battery’s natural capacity loss over years are a separate matter. Keep the receipt and the battery on the charger between seasons rather than stored dead.
Who gets the most value from the LSW36
The LSW36 pays off for homeowners with driveways, decks and garages to sweep regularly, who want cordless convenience without gas. The 40V battery, fast charger, variable speed and 3-year warranty make a complete kit for that job. Skip it if your yard drops deep leaves every fall, if you need a stated runtime, or if you want vacuum and mulching: this is a sweeper-class tool, and the 90 CFM figure says so honestly.
