Black+Decker 20V MAX Cordless Sweeper with Power Boost LSW321
Leaves that have blown under a car and dried onto the driveway need a burst, and the Black+Decker LSW321 Power Boost gives one on demand: up to 130 MPH and 100 CFM in a quiet, light sweeper that clears a driveway and a garage. It runs on the Black+Decker 20V packs shared with drills and trimmers.
Reasons to buy

Worx 20V Turbine Blower WG547
When the leaves under the car are part of a driveway full of them, the Worx WG547 turbine gives 360 CFM in a wide stream with two speeds at 4.4 pounds, so the low speed reaches under the car and the high speed clears the drive. It shares Power Share packs with the WG545.1.
Reasons to buy
- 360 CFM for the driveway
- Two speeds
- 4.4 pounds
- Same packs as the WG545.1

Why under a car is a different job
A parked car makes a wind shadow, and leaves settle under it where a rake cannot reach and a big blower bounces its stream back. Left there, damp leaves trap moisture against the underbody. The job wants a compact blower with a focused stream that throws air the width of a car under a bumper a few inches off the ground, held low or kneeling, which rules out the heavy 600 CFM handhelds and favors the light sweepers with narrow nozzles. The three here are those, and one is a slightly bigger turbine for the driveway around the car.
This guide is built from the published specifications and manuals of each blower and from recurring owner feedback. We have not run these blowers ourselves.
How the three compare
| Blower | Stream | Weight | Attachments | Battery |
|---|---|---|---|---|
| Worx WG545.1 | Focused, 120 MPH | 3.5 lb | 9 | 20V |
| Black+Decker LSW321 | 130 MPH, 100 CFM, boost | Light | Round nozzle | 20V MAX |
| Worx WG547 | Wide, 360 CFM | 4.4 lb | Standard tube | 20V |
Worx WG545.1: built for narrow spaces
Worx names narrow spaces as the purpose of the WG545.1, and the nine attachments include the long narrow nozzles that reach under a bumper and throw a 120 MPH stream across to the other side. At 3.5 pounds with the battery it is comfortable held low, and the same attachments clear a workbench, a garage corner and the floor mats of the car itself. It is a sweeper for hard surfaces and small gaps, not a lawn blower.
Black+Decker LSW321: a boost for dried leaves
Leaves that have sat under a car through a rain dry onto the concrete, and the Black+Decker LSW321 Power Boost button gives the burst that lifts them, up to 130 MPH. It is quiet and light and runs on the 20V MAX packs that power Black+Decker drills and trimmers. Its 100 CFM is low volume, which is fine under a car and slow on a driveway.
Worx WG547: for the driveway too
If the leaves under the car are part of a driveway full of them, the Worx WG547 turbine gives 360 CFM in a wide stream with two speeds at 4.4 pounds, and it shares Power Share packs with the WG545.1. Low speed reaches under the car with a little less focus; high speed clears the drive. A household with both Worx tools has the pair that covers it.
Clearing under a car
Kneel at the side the wind is coming from, aim the nozzle under the bumper toward the far side and sweep slowly along the length of the car. Have the far side open so the leaves land where a broom can take them. Do the wheel wells last, pointing down and out. Check the air intake grille at the base of the windshield while there; leaves collect in it and block the cabin filter.
Which one should you buy
Buy the Worx WG545.1 for the best focused stream and nozzles for under a car and around a garage. Buy the Black+Decker LSW321 for a boost on dried-on leaves. Buy the Worx WG547 if the whole driveway needs clearing in the same session.
How we research
This guide is built from the published specifications, manuals and warranty terms of each product and from recurring owner feedback. We have not run these products ourselves; where a maker does not publish a figure we say so rather than guess.
What to look for
Focused stream
A narrow nozzle throws air a car width under a low bumper. A wide stream dissipates.
Long narrow nozzle
Attachments that extend the reach push the stream further under the car.
Weight and size
The blower is held low, often kneeling. Under four pounds and compact.
Garage double duty
These compact sweepers also clear a garage floor, a workbench and a car interior.

Under a car is a narrow, low gap that wants a compact blower with a focused stream and a long nozzle, not a big one. The Worx WG545.1 is built for exactly that; the Black+Decker LSW321 adds a boost for dried-on leaves; the Worx WG547 is the pick when the whole driveway needs doing. Blow from one side and catch the leaves on the other.
FAQs
Kneel at one side, aim a focused stream under the bumper toward the other side and have the leaves land on open driveway where they can be swept.
The car creates a wind shadow and the leaves settle there. Clearing them matters because damp leaves under a car trap moisture against the underbody.
It works, but the wide stream bounces back and the blower is heavy to hold at ground level. A compact sweeper is faster.
The Worx WG545.1 with its narrow attachments blows crumbs and dust out of a car interior and floor mats well.
