Frequently Asked Questions

  • Does this come with a battery?

    Yes, this model includes 1 battery.

  • How heavy is the 20V AIR Cordless Leaf Blower / Sweeper?

    The great news is that it’s not heavy! The Worx AIR Cordless Leaf Blower / Sweeper only weighs 4.3lbs. With our ergonomic design to ensure even this small amount of weight is optimally distributed, clean-up has never been so effortless, comfortable or so portable!

  • Is the Worx AIR Cordless Leaf Blower / Sweeper electric or battery operated?

    Worx has an entire family of products, some of which are battery operated and some of which are electric. The WG545.4 is a battery-powered model and uses a 4.0Ah 20V Worx battery.

  • How long can you use the Worx AIR Cordless Leaf Blower / Sweeper on each 20 Volt Max Lithium battery charge?

    Runtime will vary from job to job, and sometimes between users, depending on how each person works. The battery included with your Worx AIR Cordless Leaf Blower / Sweeper will take you far, but remember you can also use any 20V Worx batteries you already have so you’ll never be out of power.

  • Is the battery larger than previous models?

    The Worx AIR Cordless Leaf Blower / Sweeper features our highest capacity battery to date. The included 20 Volt Max Lithium Battery has an amp hour rating of 4.0 compared to our previous 2.0 Ah models. The amp hour rating measures how much energy can be stored in the battery (energy capacity). The Worx 20V Max Lithium 4.0Ah battery can hold almost twice the amount of energy as previous models in the same size battery due to advanced battery chemistry. This means it will have up to double the run time of the 2.0 Ah 20V battery.

  • I already have some 20V Worx batteries, will they work in this tool?

    Yes! Powershare lets you share batteries and save money. Any 20V Worx battery you already own will be compatible with this tool, and the batteries included in this package will work on the 20V Worx tools you already have.

  • Is the battery going to be powerful enough?

    The lithium battery powering our cordless Worx AIR Cordless Leaf Blower / Sweeper is powerful to drill through concrete and large timber, so they’re definitely powerful enough for clean-up to give your lawn the professionally manicured look you’ve always wanted.

  • What’s the difference between the WG545.4 and the previous WG545.1?

    The difference between the two model numbers is the battery. The WG545.4 features a 4.0Ah battery where the WG545.1 features a 2.0Ah battery. This means the WG545.4 will have up to double the run time of the 2.0 Ah 20V battery, model WG545.1.

  • Does this use the same batteries as my other 20V Worx tools?

    Yes! With Power Share, you can share the battery and save money. Your Worx AIR Cordless Leaf Blower / Sweeper can use any 20V Worx battery you already have. By sharing the battery between tools, you’ll always have the power you need to complete any job.

  • What is the horsepower rating of Worx lithium tools?

    Battery powered DC motors are not rated for horsepower as output power is only measured with gas or induction AC (corded) motors. Worx lithium-powered products are designed with sufficient power to get the job done quickly & easily.

  • How long does it take to charge the 20 Volt Max battery?

    It takes approximately 2 hours to fully charge the battery using the charger that comes with model WG545.5.

  • Are lithium batteries interchangeable with the Ni-Cad?

    Our lithium tools and Ni-Cd tools are separate platforms and are not interchangeable. Lithium batteries offer our customers maintenance-free technology without the hassle of managing the memory effect inherent in Ni-Cad batteries.

  • Are the 20 Volt Max Lithium batteries interchangeable with the 32 Volt Max Lithium Battery?

    While Power Share allows you to share batteries between tools within the same voltage family, batteries can only be used with tools of a corresponding voltage. Use your 20V Max Lithium battery with any 20V Worx tool – even the power tools – but save your 32V battery for your 32V tools.

  • What is the horsepower rating of the Worx AIR Cordless Leaf Blower / Sweeper? How powerful is it?

    Horsepower rating is more accurately used to describe gas-powered tools. The Worx WG545.4 AIR Cordless Leaf Blower / Sweeper is powered by a 20V battery with a 4.0 Amp hour rating, which measures how much energy can be stored in the battery (energy capacity). This is twice as much capacity as our previous 20V batteries without increasing the size, an expansion achieved through advanced battery chemistry. You can depend on the power they provide. With an airspeed of 120mph, you can be sure the Worx AIR has the power to get the job done, whether cleaning up lawn trimmings or sweeping leaves off the front porch.

  • Is this also a vacuum like some of the other electric blowers Worx offers?

    The WG545.4 does not include a vacuum feature. For a complete 3-in-1 electric leaf blower/vacuum/mulcher, check out the Worx TRIVAC or the TURBINE FUSION.

  • Is the Worx AIR Cordless Leaf Blower / Sweeper variable speed? How do I change the speed?

    The WG545.4 Worx AIR is not a variable speed blower. If you’re interested in having more control over the air flow or speed, check out our Turbine family of blowers.

  • Does it come pre-assembled?

    Each Worx AIR Cordless Leaf Blower / Sweeper comes with some minor assembly required, but it will take less than 3 minutes and will not require tools.

  • Once I put the AIR together, can I disassemble it?

    Yes, you can disassemble the AIR after you’ve put it together. We make it convenient to easily switch out the accessories to meet the needs of each job. Locate the textured circle on top of the Worx AIR long tube. Press it and pull the tube away from the body of the Worx AIR. To install other accessories, line up the textured circle on the Worx AIR with the corresponding hole on the accessory and push them together until they click.

  • Are there any precautions I should follow when using the blower with damp leaves? Will I get shocked?

    Regardless of the tool or job at hand, we recommend that our customers follow standard safety precautions while using our tools, including wearing safety eyewear, gloves, appropriate shoes and clothing, and keeping hair tied back. Always refer to the owner’s manual for complete safety information before operating any tool.

    ATTENTION: The motor housing under the body of the tool is the air intake for the Worx AIR Cordless Leaf Blower / Sweeper. Keep all loose clothing, hair and debris away from this area to avoid accident, injury or damage to the tool. Hold the blower at your side and keep the back of the motor housing clear at all times.

  • Where can I get replacement parts?

    Lose your nozzle or charger for your blower? Need an extra battery? Many accessories are available online under Accessories.

  • Is the fan in the blower replaceable?

    Because of the positioning of the fan in the tool, the fan is not a part we offer as a replaceable item. Our friendly customer service team will be glad in helping you find the best solution to get you back up and running. Please contact us at 1-866-354-9679 (Worx).

Rated 5 out of 5 by from Great blower I bought this one for my daughter. I have had mine for over a year and I love it. It is powerful and lightweight. I don’t feel like my arm is going to fall off after using it.

Rated 5 out of 5 by from Very Versitile With all the accessories available it is the most versitile blower I have seen on the market. It is powerful and light weight, but does a better job than the much heavier gas model i had. One of the best purchases I have ever made.

Rated 5 out of 5 by from Lightweight, easy to use We are elderly and needed a lightweight blower for grass clippings on sidewalks, driveways and under shrubbery. Purchased this about a month ago and so far the 20 V Power Share 4.0 Ah battery lasts thru clean up without recharging and does a very good job. I have not used any accessories yet, but I am sure they will do the job.

Rated 5 out of 5 by from WorX Great I have never had one of these before and since I purchased some other power share items and they had a great deal going on I went for it. I really wanted a 20v 4a battery and they had the blower and accessories WITH the longer lasting battery for 99.00. Check the site to see how much the battery alone is. This cleans my driveway, garage, walkways, and I even use it to dry off my car after washing. I purchased the gutter cleaning kit as well. It will save me hundreds each year from hiring someone. I highly suggest this!

Rated 5 out of 5 by from Got my own Worx!!!! My neighbor introduced me to Worx by loaning me her blower, I've been hooked ever since. I just had to buy my own tools from Worx. I LOVE my Worx blower with 4 ah battery. It is perfect. This battery is a game changer. Lots more time to get my job done plus extra time to start another project. Thank you Worx for creating functional yard tools that are powerful and easy to use. I Love not having to drag around a cord. I couldn't be happier with my purchases from Worx. I highly recommend your products to anyone who will listen!' I'm proud to be the owner of such great tools that make my property look really nice!! Worx Works for me!!!!!

Rated 5 out of 5 by from Long time using Worx products I bought this for my 93 year old mother, yes 93 and she loves it. She lives by herself and I am concerned for her safety, she uses a broom on the sidewalk, but has to step out of the house. So now she can blow the sidewalk off and if it can't be remove, time to call grandkids. What important here, she never has to take that first step outdoors

Rated 5 out of 5 by from Perfect for Women I started out buying Work tools years ago for my husband. When my sister asked for a leaf blower for Christmas, I immediately turned to Worx since we had always been happy with our past purchases. This tool was a HIT! My sister was so happy with it. She opened up the box and added the extensions and carried it around and said she loves it. I'm so happy that Worx has come to my rescue again. Great Purchase!

Rated 5 out of 5 by from Great Product Wife Love Her Air Cordless Leaf Blower. This is her second leaf blower; she use it almost dayily. Easy to handle and the 4.0 Ah battery lasts a long time. The charging time is quick. Of all the cordless blower I have purchased over the years, this is the best. Recommend this for the little lady that likes to get out and do yard work.

Rated 5 out of 5 by from Perfect for my needs! I love my Air Cordless Leaf Blower! Just received it about a week ago and already used it several times. So easy - just pick it up and go. I already owned a corded leaf blower. As a female senior citizen, the added weight of the extension cord made it cumbersome for me. Consequently, I did not use it very often. My WORX AIR Cordless is so convenient and light weight to use and has the power to clear my deck and porch of leaves from my large water oak. I opted for the 4.0 battery and the charge held to clear my 24'-24' deck and front porch, ramp, and walk. It also re-charges quickly. I am so happy with my purchase!

Rated 5 out of 5 by from Powerful and very handy. I'd been playing around with the idea of purchasing the "AIR Cordless Leaf Blower/Sweeper Hi-Capacity (4.0AH) for some time to replace my old gas blower, and a couple of weeks ago I did. Once I received the blower, I took it out and assembled it (very easy) and charged the battery. Then I used it blow a pile of leaves that were beginning to accumulate outside my front entry door. Wow, I was very impressed with it's power, lightness and ergonomic design. After using it, I thought "why did I wait so long to order it." This is a quality tool and well designed, and it didn't even use 1/2 the battery charge. A couple of days later I had another pile of leaves in front of my garage door, so once again, I grabbed the blower and quickly cleared them completely off my double wide driveway. Even though the leaves were wet and heavy, the blower blew them away easily and still I had over 1/2 battery life still on the battery. This was a great purchase of a well designed and built tool. Now I'm thinking of other uses for it like blowing snow off of our cars and walk ways, cleaning grass clippings off of the walks, driveway and mowers. The other plus is that the battery is interchangeable with my other 20 volt Worx tools, so I'll always have ample power for any project.
