The Greenworks G-MAX 40V Leaf Blower/Vacuum is an excellent alternative handheld for working on smaller projects.  It is not by any means the most powerful when compared to gas and other corded models.  However, what makes this unit stand out is its ability to function without the need for gas or tripping over cords.


Specifications and performance:

This unit weighs in at around 6lbs with the battery which is not bad when compared to its gas counterparts. This weight may vary according to which battery you use and the vacuum tubes when attached.  The body looks well-built and has that signature green color associated with most Greenworks products.

Conveniently located on the handle are three controls: a power button, a turbo button, and a variable speed dial directly below. The variable speed option starts from 1 to 5 with 5 being the highest setting. These controls lay flat against the surface making it awfully hard to turn the unit on if wearing a glove.

The Greenworks G-MAX 40V Leaf Blower has enough power for doing average chores around the yard. Clearing tiny amounts of leaves, blowing off driveways, and lawn clipping down should be no challenge. It, unfortunately, starts to struggle when working on a larger pile of debris that’s damp. Operation is quiet making it ideal for doing work at odd hours or locations that require you to be a bit inconspicuous.

Battery performance.

This setup (Model:24322) comes with a G-MAX 40V 4Ah Battery, which is also in interchange with all Greenworks 40v lines of products. You can optionally purchase a slightly smaller 2ah version. Having a smaller battery should reduce the overall weight of the blower. The difference will not be noticeable unless working longer periods.

Run time for the 4ah averages around 30-45 minutes and takes about one hour to charge. They are four indicators built into the battery, so you know how much runtime remains. The battery at times seems to get stuck within the unit requiring a bit of force to pry it loose but could be a result of accumulated dirt.

Using the Vacuum Feature

Greenworks G-MAX 40V Leaf Blower/Vacuum Review

One of the biggest selling points of this unit is its conversion from a blower to a vacuum. Greenworks is currently one of the few companies offering a cordless blower /vacuum on the market. The conversion process is quite simple and takes less than a minute (Instructions are located on the suction tube and manual). This handy feature is especially useful for sucking up grass clippings, dry leaves, and other light debris.

The vacuum fan blade is plastic, however, it features a second metal blade that is for shredding. While operating you should be careful not to suck up too much debris all at once since the suction tubes tend to become clogged very easily. The highest setting gives the best result when working with large piles.

Constant awareness of the bag position is will help you avoid unnecessary damage. The bag’s thinner material can easily be ripped when dragged across a rougher surface like concrete. To prevent this, you should use the shoulder strap attached to the bag. It is also a good idea to wear a face mask since the bag does not do a great job of filtering dust particles.


The Greenworks G-MAX 40V Leaf Blower/Vacuum is a well-worth investment for the average homeowner. Gas-powered blowers are just not practical for smaller garden work, these classes of equipment are best suited for bigger projects or commercial work. If you are looking for the best balance between performance and affordability, then this blower is an excellent choice.
