Air Speed and Air Volume of Worx WG512

From this number, you can see that WG509’s speed is higher, even at its lowest. It means that it can perform better in tighter places in contrast to WG512. However, we still have the volume to consider. The air volume for the WG509 is 350 cfm which goes against WG512’s 600 cfm. In this case, WG512 has a higher number, which means it can move large piles of leaves better.

Accordingly, WG512 wins because it has a larger air volume, and consequently, it can help you move more leaves without going back and forth.   

– Mulching Ratio

Winner: Worx WG509 

As stated above, these two blowers have a mulching function, which means it’s essential to look at the mulch ratio as well. The mulch ratio of WG509 is 18:1, which goes against WG512’s 16:1.

Worx WG509 Review


  • Has two different speed modes 
  • Easily switchable functions 
  • High mulching ratio


  • A little heavy blower 

Worx is a reputable brand in the industry with popular blowers, one of them being the WG509. This blower has a power input of 12 AMPS. The dimensions of this blower are as follows: 20 inches (L) x 15 inches (W)x 9 inches (H). It is an electric blower, which means it does not have a tank, which reduces the weight of the blower significantly. 

The weight of the blower is 11 lbs. The low weight of the blower makes it easier to handle and maneuver. Furthermore, it’s a user-friendly blower. Firstly, it has three functions in one, which are blowing, vacuuming, and mulching

Another advantage of this blower is the fact that the change of function does not require any tools or other changes of tubes. The only thing you will need is the switch. The vacuuming function of the blower is also powerful and will save time for you to dispose of the piles afterward. And the final function of this three-functioning blower is mulching. 

The mulcher is a metal impeller, which is not only durable but also cuts in two stages. The next impressive factor about mulching is the ratio. The ratio is 18:1, which means it makes one mulch bag out of 18 bags. This way, you will not need to spend too much time mulching and can complete your task faster. 


And lastly, it’s designed for the operator to use it only with one hand. It will help you to have a free hand and allow more flexibility. The  WG509 only has one downside – it’s relatively heavier. This downside, however, doesn’t outshine all the positives, and in the end, you have a powerful blower, vacuum, and mulcher in one device. 

Worx WG512 Review


  • Adjustable speed modes 
  • Lighter blower 
  • Three functional stages 


  • Louder blower

Another popular electric blower from Worx is WG512. It is one of the lighter models, only weighing 8.6 lbs. The WG512 has an input power of 12 AMP and item dimensions are 35.5 (L) x 10 (W) x 14 inches (H). Similar to other Worx blowers, it also has a two-speed mode

The speed modes allow the operator to speed down or speed up the blower according to the place where they’re cleaning. Furthermore, it’s also a three-in-one blower. It means that by choosing WG512, you will have vacuuming, mulching, and blowing functions. Another plus of this blower is its detachable bag. 

This bag is designed for a clean and easy composting or mulching process. During the detachment, it doesn’t create dirt, making rather dirty work a quick and relatively clean process for you. Despite being made of plastic, it also has a metal impeller.  

This way, you can make sure that you have a durable impeller with shredder blades. The ratio for the WG512 is 16:1, which means it can mulch 16 bags into one. Furthermore, similar to other Worx blowers, the switch between functions is done by one switch. This product only has one downside – the sound level. 


The sound level is 79 dB (A). The relatively high sound pressure can mostly affect where you can use this blower. A blower with this sound capacity is perfect for someone who has a large property or who lives in a remote area. 


Overall, the Worx WG509 won three out of five categories. This model is a fantastic choice for someone looking for a blower with a higher mulching ratio and quiet operation.

On the other hand, the Worx WG512 is a perfect choice for someone who needs a blower with more air volume and power to take care of their large piles of leaves.
