In a big yard, raking and bagging leaves can eat several weekends. A leaf vacuum mulcher sucks leaves up, shreds them and drops them in a bag, cutting a pile down to a fraction of its size. Many models do it at ratios of 10 to 1 or more, meaning 10 bags of leaves become one.

For large yards, power and capacity matter most. Corded models are limited by the cord, and battery models run out of charge fast in heavy leaves. Gas handhelds and walk-behind vacuums are built for big jobs.

The picks compared

Test notes are from Bob Vila's leaf vacuum testing, which ran each model on fresh and year-old leaves, wet leaves, twigs and acorns, and checked how finely each one shredded.

How we researched these picks

We relied on Bob Vila’s leaf vacuum testing, which built leaf piles in blower mode, then vacuumed and shredded fresh, old and wet leaves, twigs and acorns, and checked how finely each one ground the debris. For large yards, we prioritized power and capacity over light weight.

• Power and clog resistance
• Mulch quality
• Capacity
• Weight and comfort

We haven’t tested these leaf vacuums ourselves. Read more about how we pick products.

1. Billy Goat KV601SP Walk-Behind Leaf Vacuum: Best for large yards

Best for: Big properties with lots of trees.

Bob Vila’s walk-behind pick has a 26-inch intake that picked up everything in its path, including clumped grass clippings, twigs and pine cones. Its impeller never clogged in testing. It’s self-propelled and has an adjustable nozzle height and a large, zipperless 4-bushel bag.

What bugs us: Wet, matted leaves sometimes needed a second pass, and long sticks partly blocked the nozzle. It’s bulky to store, and the hose kit for beds and corners is sold separately.

Skip it if: you don’t have room in the garage for a 132-pound machine.

2. Stihl SH 86 C-E Shredder Vac: Best gas handheld

Best for: Big leaf loads, including wet ones.

The Stihl vacuumed dense, wet leaves faster than anything else Bob Vila tested. It handled acorns and twigs, started on one pull and has vibration dampening to cut hand fatigue.

What bugs us: It’s heavy at 12.3 pounds, and loud enough that you’ll want ear protection.

Skip it if: you’re sensitive to noise and vibration.

3. Husqvarna 125BVx Leaf Blower and Vacuum: Best value gas

Best for: Large gardens with heavy leaf fall.

The Husqvarna started in two pulls, its tube stayed clear even with wet debris, and its mulching knives shredded twigs well. Cruise control, an anti-vibration handle and a shoulder strap help on long jobs.

What bugs us: The rigid bag tube is awkward, converting from blower to vacuum is clumsy, and it runs on mixed fuel.

Skip it if: you don’t want to mix gas and oil.

4. Toro 51621 UltraPlus Leaf Blower Vacuum: Best electric

Best for: Medium yards near outlets, or the beds and patio of a big yard.

Bob Vila’s best overall leaf vacuum handled leaf loads without clogs and only slight hesitation in heavy piles, at a light 8.9 pounds. It blows, vacuums and shreds, with a 16-to-1 mulch ratio and a sturdy bag with a shoulder strap.

What bugs us: You need an outlet and a long extension cord, and wet leaves move slowly. The vacuum tube connection is clumsy and may be long for shorter users.

Skip it if: your yard runs more than about 100 feet from an outlet.

Tips

• Vacuum dry leaves when you can. Wet leaves clog tubes and fill bags faster.
• Keep sticks and rocks out. They can damage the impeller.
• Use shredded leaves as mulch in beds or add them to compost.
• Wear eye and ear protection and a dust mask in dry conditions.

Still wondering?

Is a leaf vacuum better than a blower? For large yards, a blower is faster at moving leaves into piles. A vacuum mulcher shines for bagging and shredding those piles.

What does mulch ratio mean? How much leaves shrink. A 16:1 ratio turns 16 bags of leaves into about one.

Can I just mow leaves instead? Yes. A mulching mower shreds a light leaf layer and leaves it on the lawn. Heavy leaf fall still needs bagging.
