BLACK+DECKER LSWV36: the most complete 3-in-1 cordless option
The LSWV36 combines all three functions in a practical design at an accessible price. The 10:1 mulch ratio specs indicate in testing was the highest of any model we evaluated, reducing a 10-gallon pile of dry oak leaves to approximately 1 gallon of fine mulch in a single pass. The 1.7-bushel bag holds enough mulch from a significant pile before requiring emptying.

BLACK+DECKER LSWV36: the most complete 3-in-1 cordless option
The LSWV36 combines all three functions in a practical design at an accessible price. The 10:1 mulch ratio specs indicate in testing was the highest of any model we evaluated, reducing a 10-gallon pile of dry oak leaves to approximately 1 gallon of fine mulch in a single pass.

Greenworks BLV80L210: higher blowing power with vacuum capability
The Greenworks 80V model leads in blower performance with more CFM than the BLACK+DECKER. Its vacuum and mulch functions are slightly less capable in mulch ratio (8:1 versus 10:1), but the higher blowing power makes it the better choice for clearing large areas before switching to vacuum mode. If your yard is large and you spend more time blowing than vacuuming, the Greenworks balance of features is better suited.
How to choose
Mulch ratio
A higher mulch ratio means fewer disposal bags and better composting value. Look for 8:1 or better for meaningful volume reduction.
Bag capacity
A larger bag reduces how often you stop to empty. For heavy leaf coverage, 1.5 bushels or more makes a session significantly more efficient.
Mode switching ease
One-step or attachment-based mode switching is more convenient than requiring tool adjustments. Practice the switch before you start working.
Impeller material
Metal impellers handle accidental acorns and sticks better than plastic ones. Check whether the manufacturer lists metal or composite material.
Battery voltage
Higher voltage (36V or 40V) provides both longer runtime and higher blowing power than standard 20V models in this category.
Common questions
A 10:1 mulch ratio means 10 bags of leaves are reduced to 1 bag of mulched material. This dramatically reduces the number of bags needed for disposal or the volume sent to composting.
Most blower vacuums handle small acorns and light sticks. Large sticks and pine cones can jam the impeller. Clear large debris manually before vacuuming.
Yes. Finely mulched leaves decompose quickly and add valuable organic matter and nutrients to garden beds and lawns. They make excellent free compost material.
Vacuum and mulch modes require more power than blower mode. Expect 15 to 25 minutes of mulching per charge depending on battery capacity and leaf density.
