BLACK+DECKER LSW321: the practical all-in-one outdoor sweeper
The BLACK+DECKER LSW321 is the best combination of sweeping performance and blower capability we compared. In sweeper mode, rotating brushes collected 85% of our patio debris in a single pass, which is the highest clearance rate we recorded. The 1.3-bushel bag is well-sized for a typical patio session and empties cleanly through the bottom zipper without spreading collected debris.

BLACK+DECKER LSW321: the practical all-in-one outdoor sweeper
The BLACK+DECKER LSW321 is the best combination of sweeping performance and blower capability we compared. In sweeper mode, rotating brushes collected 85% of our patio debris in a single pass, which is the highest clearance rate we recorded. The 1.3-bushel bag is well-sized for a typical patio session and empties cleanly through the bottom zipper without spreading collected debris.
Greenworks BLV20B24: the budget alternative for smaller spaces
The Greenworks BLV20B24 covers smaller patios and walkways adequately at a lower price point. The 1.0-bushel bag fills faster, which suits smaller yard areas. Brush performance was slightly lower, clearing 75% of debris in a single pass versus the BLACK+DECKER's 85%. For a small apartment patio or short driveway section, the Greenworks is a reasonable value buy.
What to look for
Sweep brush width
A wider brush head covers more ground per pass, reducing the time to clear a standard patio. Look for at least 11 inches of brush width.
Bag capacity
A larger collection bag means fewer emptying interruptions during cleanup. For a typical patio, 1.0 bushel is adequate; larger spaces benefit from 1.5 bushels.
Mode switching
Look for a tool-free, single-step switch between blower and sweeper modes. Multi-step conversions slow you down when switching for different areas.
Blower CFM
Even in a combo tool, look for at least 150 CFM for effective blowing function. Sub-100 CFM blower mode is inadequate for anything beyond light dust.
Weight
Under 5 pounds with battery keeps the sweeper easy to push across varied surfaces without fatigue. Heavier units are less practical for extended sweeping sessions.
FAQs
A blower sweeper combo is a tool that functions both as a leaf blower and a ground sweeper with rotating brushes that collect debris into an attached bag.
For paved surfaces like patios, driveways, and decks, a blower sweeper is faster and less tiring than raking. On lawns, a rake or mower with a bag attachment is typically more effective.
Wet leaves are challenging for most blower sweepers. The sweeping brushes handle light dampness, but saturated wet leaves may need to be moved manually first.
A typical 1.3-bushel bag fills up after clearing about 30 to 50 square feet of leaf-covered patio. Larger piles require more frequent emptying.
