Overview of the Worx WG521

  • Power: The Worx WG521 can force 800 cubic feet of air per minute (CFM) from its nozzle at a maximum speed of 135 MPH.
  • Power delivery: This unit, featuring a 12 Amp motor, is a corded blower. It must be plugged into an electrical outlet with a reliable power source at all times during operation. Please note that some manufacturers don’t include the cord with the unit. If this is the case, or if you’re looking to buy a backup, please use our gauge calculator to ensure you’re buying the right cord for your blower.
  • Cord Lock Mechanism: It has a cord lock mechanism, so there’s far less risk of having the cord come unplugged when the unit is in operation.
  • Handling: For those who are looking for a portable and convenient leaf blower, this model is a strong candidate. It’s designed for easy handling and use, and its size means it’s easily carried and stored. All told, it weighs 6.6 lbs — the Worx WG521 is neither the lightest nor the heaviest electric handheld blower on the market.
  • Speed Settings: Sometimes you just need a little more power, while other times you may want a little more precision when moving leaves and debris. That’s why the WG521 features variable speed settings for added control.
