Which battery leaf blowers publish both airflow and airspeed and remain effective on wet leaves without excessive noise?

If you want both published CFM and MPH, enough force for wet leaves, and relatively low noise, I’d narrow the field to these:

*Noise figures aren't perfectly comparable because manufacturers/testers can use different measurement conditions.

My shortlist

1. EGO LB7654 — strongest combination of wet-leaf performance and relatively modest noise

• EGO Power+ LB7654 200 mph 765 CFM 56 V Battery Leaf Blower - $359.00 (Ace Hardware)

EGO publishes 765 CFM and 200 MPH, and specifically says Turbo mode is intended for heavy debris including wet leaves, mud and snow. Its 64-dB figure is surprisingly low given the output; an independent test also recorded 64 dB.EGO Power++1

The combination is useful for wet leaves because CFM gives you the volume of air to move a pile, while MPH helps break leaves loose when they're stuck to pavement. The EGO has unusually high numbers for both.

2. Greenworks Pro 80V 730 CFM — strong wet-leaf option

• Greenworks Pro 80V 730 CFM / 170 MPH Blower - $199.99 (Walmart - Supply the Home)

Greenworks explicitly rates this at 730 CFM / 170 MPH and says it's designed for wet and heavy leaves. Greenworks Tools An independent test measured about 67 dB, so it's reasonably quiet for a high-output blower, although Greenworks doesn't appear to publish its own noise specification on the product page.WoodworkingToolsHQ

3. DEWALT DCBL777 — worth considering if noise reduction is particularly important

• DEWALT FLEXVOLT DCBL777 760 CFM / 160 MPH - $299.00 (The Home Depot)

This newer FLEXVOLT model publishes 760 CFM and 160 MPH and uses foam/optimized fan geometry specifically for quieter operation; the retailer description says it produces up to 78% less noise than gas blowers. It's therefore an interesting middle ground between the EGO's very high output and a genuinely quiet lower-output blower.

One important trade-off

The Makita XBU03Z is the quietest of these on published manufacturer data at 60 dB(A), but its 459 CFM/116 MPH output is substantially lower. Makita also gives it water/dust protection, but I'd choose it for ordinary leaf cleanup rather than heavy, rain-soaked leaves stuck to a driveway.Makita Tools

So, if wet leaves are a primary requirement, I'd concentrate on the EGO LB7654, Greenworks 80V, and DEWALT DCBL777. If noise is the overriding concern, the Makita becomes more attractive, but you're giving up considerable wet-leaf performance.

• EGO POWER+ LB7654 - $359.00 (Ace Hardware)
• Greenworks Pro 80V 730 CFM - $199.99 (Walmart - Supply the Home)
• DEWALT FLEXVOLT DCBL777 - $299.00 (The Home Depot)
• RYOBI 40V HP Whisper 650 CFM - $249.00 (The Home Depot)

If you tell me your budget and whether you already own EGO/Greenworks/DeWalt/Makita batteries, I can narrow this to the 2–3 most sensible choices.

Yes. If by “effective on wet leaves” you mean enough air volume to move piles plus enough airspeed to break leaves loose from damp grass, I’d narrow the field to these:

The RYOBI 800 CFM model is particularly interesting: it publishes 800 CFM and 180 MPH, while being part of RYOBI's Whisper Series. The current product listing confirms those headline figures.ToolShed Tested

• RYOBI 40V HP Brushless 800 CFM Whisper Series Blower - $279.00 (The Home Depot)

My picks

• Best overall for wet leaves + noise: RYOBI 40V HP Whisper 800 CFM. It has the volume to move piles and 180 MPH to attack leaves stuck to wet grass. A recent comparison specifically identifies the Whisper series as unusually quiet while maintaining substantial output.Mow & Meadow
• Best for really stubborn wet leaves: EGO LB7654. Its 200 MPH maximum is the strongest airspeed of these choices, and independent testing/comparison puts it around 64 dB. That extra velocity is useful when leaves are matted down.WoodworkingToolsHQ+1
• Best less-expensive/less-powerful option: EGO LB6504, at 650 CFM/180 MPH and about 64 dB. It gives you a particularly good CFM-to-MPH balance without moving into the biggest blowers.ToolShed Tested
• Best if low noise matters more than wet-leaf power: Makita. Its XBU04/XBU02 family is around 473 CFM/120 MPH and roughly 60–61 dB in published comparisons, but that lower airspeed makes it less attractive for leaves glued to wet turf.

One important caveat: CFM and MPH are often maximums measured under different configurations/nozzles, so don't assume 800 CFM and 180 MPH occur simultaneously. For wet leaves, I'd put considerably more weight on airspeed + usable variable-speed control than on CFM alone.Mow & Meadow

If I were buying specifically for damp fall leaves in a residential neighborhood, I'd choose the RYOBI 800 CFM Whisper for the best power/noise compromise, or the EGO LB7654 if maximum wet-leaf performance matters more than absolute quietness.

Yes. If your priorities are published CFM + MPH figures, good wet-leaf performance, and reasonable noise, I’d narrow the field to these:

1. EGO POWER+ LB6504 — best match

• RYOBI 40V HP Brushless Whisper Series 650 CFM Blower - $249.00 (The Home Depot)

The EGO LB6504 is the one I'd choose if wet leaves matter most. EGO explicitly rates it at 650 CFM and 180 MPH, with a turbo mode intended for heavy debris including wet leaves. It also has IPX4 weather resistance and a published 64 dB sound-pressure rating.Lowe's+1

The combination matters: CFM gives you the volume of air to move a pile, while MPH helps break loose wet/matted leaves. EGO's 650/180 combination is unusually strong for a handheld cordless blower.EGO Power Plus

2. RYOBI 40V HP Whisper Series — potentially better if noise is the priority

The RYOBI RY404014 publishes 650 CFM / 160 MPH and is specifically marketed as part of its Whisper Series. That's nearly EGO-level airflow, while giving up some air velocity.ToolShed Tested

• RYOBI 40V HP Brushless Whisper Series 650 CFM Blower - $249.00 (The Home Depot)

I'd favor this over the EGO if noise around neighbors is more important than maximum wet-leaf force.

3. Makita XBU03Z — quieter, lighter, but less forceful

• Makita XBU03Z 459 CFM / 116 MPH - $179.00 (The Home Depot)

The Makita publishes 459 CFM and 116 MPH and is explicitly described as a lower-noise cordless blower. It's substantially lighter than the big 40/56V machines, too.ToolShed Tested

The tradeoff is wet leaves: 459 CFM / 116 MPH is adequate, but you're more likely to need to get close to soaked or matted leaves and make multiple passes.

4. Milwaukee M18 FUEL — good middle ground

• Milwaukee M18 FUEL 500 CFM / 120 MPH - $149.00 (The Home Depot)

The current M18 FUEL 3017-20 is rated 500 CFM / 120 MPH. It's a good choice if you're already invested in Milwaukee batteries and want a relatively compact blower rather than maximum yard-clearing power.ToolShed Tested

Bottom line

For wet leaves + low-ish noise, I'd rank them:

1. EGO LB6504 — best combination of wet-leaf power and published noise rating.
2. RYOBI 40V HP Whisper 650 CFM — very compelling if minimizing perceived noise is especially important.
3. Milwaukee M18 FUEL 500 CFM — good compromise and excellent if you own M18 batteries.
4. Makita XBU03Z — quiet/light, but I'd choose it for routine cleanup rather than heavily soaked leaves.

One caveat: manufacturer dB figures aren't necessarily measured under identical conditions, so don't treat 64 dB EGO versus a competitor's unspecified "quiet" claim as a laboratory apples-to-apples comparison. Also, for wet leaves, I'd prioritize CFM first and MPH second, rather than buying based on MPH alone.ToolShed Tested

3. Makita XBU03Z — quieter, lighter, but less forceful

• Makita XBU03Z 459 CFM / 116 MPH - $179.00 (The Home Depot)

The Makita publishes 459 CFM and 116 MPH and is explicitly described as a lower-noise cordless blower. It's substantially lighter than the big 40/56V machines, too.

The tradeoff is wet leaves: 459 CFM / 116 MPH is adequate, but you're more likely to need to get close to soaked or matted leaves and make multiple passes.
