Description
Incredibly powerful. Unbelievably quiet. The 40V Backpack Blower with CROSSFORCE FAN TECHNOLOGY™, a unique dual-intake design, is the industry’s quietest blower. With its brushless motor and lithium-ion battery, it generates 625 CFM of clearing force.
Zoom on the Ryobi RY40440
With its cordless backpack design, the Ryobi RY40440 is a good match for both homeowners with properties with wide lawns, large gardens, or estate-sized grounds over half an acre, and professionals handling medium-to-large yards for clients.
It is capable of expelling a maximum air volume of 625 cubic feet per minute (CFM). Its air speed is rated at 145 MPH. In practice, it should move both scattered leaves and larger piles across yard areas, while also clearing heavier debris such as acorns, pine cones, or pine needles on patios or driveways.
The RY40440 features a 40V brushless motor, providing cordless operation for flexibility and mobility. It is supplied with a 5.0Ah battery which can offer up to 30 minutes of runtime per charge.
Users seeking ease of use will appreciate the RY40440's variable speed settings for precise airflow adjustment and cruise control for consistent operation.
This cordless backpack blower weighs 21.1 lbs as a bare tool and 25.1 lbs with the battery installed, carrying most of its weight on the back so the user only supports the tube with one hand. Its throttle is located on the tube, which allows to keep the left hand free.

The Ryobi RY40440's performance versus other blowers
The following charts are provided to give you an idea how the key specs of the Ryobi RY40440 compare with other cordless backpack leaf blowers.
- Weighing 21.1 lbs without the battery, the Ryobi RY40440 is heavier than many cordless backpack blowers in the 36 to 40V range. To enjoy the lowest possible weight in this category, you could have a look at the Ryobi RY40HPLB02K which is only 13.2 lbs the bare tool.
- Maxing out at 145 MPH at full power, this blower is on the lower end in terms of air speed for battery-operated backpack blowers. For the fastest air speed in this category, you may want to consider the Stihl BGA 300, which can expell air at a velocity that can reach 192 MPH.
- Its air volume, rated at 625 CFM, is typical among cordless backpack blowers with a comparable voltage. If air volume is important to you, the Ryobi RY40HPLB02K, with 850 CFM, could be in your good books.
- Autonomy-wise, with up to 30 minutes of autonomy on a full charge, the RY40440 is on the low end when compared with other cordless backpack units. To enjoy the best possible autonomy in this category, you could have a look at the Makita CBU02Z which offers up to 240 minutes of runtime.
- Runtime alone doesn’t always tell the full story because it depends heavily on battery capacity. Runtime efficiency can give a clearer picture by showing how much work you get per unit of battery power. Runtime efficiency for the Ryobi RY40440 sits comfortably in the middle of the range for battery-powered backpack blowers. If runtime efficiency matters most to you, you might look at the Ryobi RY40HPLB02K, which delivers a higher runtime efficiency of 0.23 minutes per Wh.
Price comparison
As you can see from these interactive charts, the Ryobi RY40440 is the cheapest of all 36-40V cordless backpack blowers.
It can therefore be a really good buy if you're looking to acquire a budget blower.
