Which is better for mulching leaves?

The Worx WG509. Its two-stage metal impeller mulches at 18:1 and feeds a 1.2-bushel bag, while the BLACK+DECKER BV3600 mulches at 10:1 into a 499 ml bag. You will empty the BLACK+DECKER far more often.

The BLACK+DECKER BV3600, at 230 mph and 385 cfm versus 210 mph and 350 cfm for the Worx. The gap is modest, but the BLACK+DECKER has the edge on driveways and patios.

Which is easier to carry?

The BLACK+DECKER at 8.1 lbs. The Worx weighs 9.3 lbs, or 8.6 lbs in blower mode. Both are one-hand handheld designs, so the difference is small.

Is the Worx worth the extra money?

There is barely any extra: $76.99 at Best Buy versus $78.00 at Amazon as of November 4, 2026. If you vacuum and mulch, the Worx is the better value. If you only blow, save the hassle and take the lighter BLACK+DECKER.

Do either run without a cord?

No. Both are corded 12-amp electric tools, so runtime is unlimited but you are tied to an extension cord. Neither is cordless.

The Worx has a metal impeller, which holds up better against twigs and grit than the BLACK+DECKER's plastic Vortex impeller. Both are homeowner-grade corded units, so expect similar motor life with normal use.

The price gap is about a dollar, so pick on mulching and bag capacity, not cost.
