A leaf vacuum mulcher blows leaves, sucks them into a bag, and shreds them so you haul away far less. We put two WORX corded models, a WORX cordless kit, a BLACK+DECKER corded model, and a Greenworks cordless kit side by side on price, power, airflow, and warranty, so you can see which one fits your yard.
How We Chose
We compared five 3-in-1 blower, vacuum, and mulcher tools from three established brands, all available on Amazon. The tools are not identical. The WORX WG509 and WG512 and the BLACK+DECKER are corded 12 amp tools, while the Greenworks and the WORX WG583 are cordless kits with batteries and chargers, so the price gap partly reflects the battery system. The airflow figures also differ (340 to 600 CFM), and BLACK+DECKER publishes an air speed of up to 230 MPH but no CFM figure. The manufacturers describe the shredding in different ways: a mulch ratio for the WORX models, bags reduced to one for the BLACK+DECKER, and no figure at all for the Greenworks. Where a value was not published we say so. The WORX, Greenworks and BLACK+DECKER product pages supplied the specs and warranties shown in the table and cards, and each card’s warranty line names its source. Greenworks does not publish a mulch ratio or a collection bag size, and the BLACK+DECKER page lists a dustbin capacity of 499 ml rather than a bag size. We take warranty terms from the manufacturer’s own website where it names the model or product line, and we say so where it gives no length. Prices are Amazon prices checked in October 2026 and can change.

Check Price on Amazon →Our Take
We would start with the WORX WG509 if you want an 18:1 mulch ratio at a low price, since it is corded and within a dollar of the cheapest. The BLACK+DECKER BV3600 is the cheapest and lists a 2 year warranty, and the WG512 lists higher airflow than the WG509 for about $7 more. If you want a cordless kit that works with a growing set of tools, we like the Greenworks as the lower priced kit at $199.99 with a 3 year warranty. The WORX WG583 costs the most at $279.99, and it adds a 12:1 mulch ratio, a 1.0 bushel bag and a 3 year tool warranty. Corded tools never run out of battery, but you are limited by the cord.

Frequently Asked Questions
What is the difference between a leaf blower and a leaf vacuum mulcher?
We think of it as one tool doing three jobs. A leaf vacuum mulcher can blow, vacuum, and shred leaves into a bag. All five tools here list 3-in-1 blower, vacuum, and mulcher functions with a tool-free conversion between modes.
What does the mulch ratio mean?
We read it as how much the tool shrinks the leaves. The WORX WG509 lists 18:1, the WORX WG512 lists 16:1, the WORX WG583 lists 12:1, and the BLACK+DECKER lists 10 bags down to 1. Greenworks does not publish a ratio. A higher ratio means fewer bags to haul.
Are corded or cordless leaf vacuum mulchers better?
We would decide by yard size and how close an outlet is. The WORX WG509 and WG512 and the BLACK+DECKER tool are corded, so you do not need to charge batteries but you need an outlet and an extension cord. The Greenworks and WORX WG583 kits include batteries and chargers.
Which of these has the longest warranty?
We would look at Greenworks and WORX first for warranty length. Greenworks’ page lists 3 years on both the tool and the battery, WORX’s pages list 3 years for the WG509, WG512 and WG583, and BLACK+DECKER’s page lists 2 years limited for the BV3600.
What does the BLACK+DECKER BV3600 offer?
BLACK+DECKER’s product page lists a corded 12 amp motor with two speeds, air speeds up to 230 MPH, and mulching that reduces 10 bags to 1, with a 2 year limited warranty. It costs $78.33 here.
