EGO LB6151: mulches leaves so well you might forget about raking
The EGO LB6151's 16:1 mulch reduction ratio was the standout performance of our testing period. In practical terms, that means a lawn covered in 2 inches of oak leaves can be vacuumed and returned to a compact bag in a fraction of the time raking would require. The turbine fan spins at high RPM to shred leaves before they reach the bag, producing a fine mulch suitable for composting or lawn top-dressing.

EGO LB6151: mulches leaves so well you might forget about raking
The EGO LB6151's 16:1 mulch reduction ratio was the standout performance of our testing period. In practical terms, that means a lawn covered in 2 inches of oak leaves can be vacuumed and returned to a compact bag in a fraction of the time raking would require. The turbine fan spins at high RPM to shred leaves before they reach the bag, producing a fine mulch suitable for composting or lawn top-dressing.
Greenworks BLV80L210 80V: powerful and lighter
The Greenworks 80V leaf vac produces excellent suction and a solid 12:1 mulch ratio at 0.5 lbs less than the EGO. For users who prioritize reduced arm fatigue over maximum mulch reduction, this is the more comfortable option on long sessions. The 80V motor is impressively quiet for the output it delivers. Battery life is shorter per charge due to the smaller 2Ah included battery, but the 60-minute charger is fast.
How to choose
Mulch reduction ratio
Higher is better. 10:1 is acceptable; 16:1+ dramatically reduces disposal trips and time. This single spec determines how much the machine saves you in autumn.
CFM and MPH
CFM (volume) determines vacuum suction. MPH (speed) determines blower effectiveness. Both matter for a 3-in-1 unit. Look for 400+ CFM and 130+ MPH in vacuum mode.
Conversion speed
Tool-free mode conversion in under 60 seconds keeps the workflow efficient. Some units require tool changes or multiple steps.
Bag capacity and access
A 1.5-bushel or larger bag reduces emptying frequency. Easy-access zipper or dump port prevents mess during emptying.
Weight in vacuum mode
Vacuum mode adds the tube and bag weight. Check the fully configured vacuum weight, not just the base unit, to assess arm fatigue potential.
Common questions
Modern 56V cordless leaf vacuums match gas for suction and mulching on most residential properties. Gas units still have the edge for very large properties due to continuous runtime.
Mulch ratio is how much the machine compresses leaves. A 16:1 ratio means 16 bags of leaves mulch down to one bag, dramatically reducing trips to the yard waste bin.
A 5Ah 56V battery typically runs 30-45 minutes in vacuum mode. Blower mode is more efficient and can run 45-60 minutes.
Wet leaves clog impellers faster and reduce mulch ratio. Most manufacturers recommend using vacuum mode only on dry leaves. Wet leaves are better blown into piles for raking.
