What the WG509 Actually Is
The WORX WG509 TRIVAC is a corded electric 3-in-1 lawn tool that works as a leaf blower, a yard vacuum, and a leaf mulcher. It is not the WG520 Turbine 600, which is a blow-only unit. The TRIVAC is built around a single housing that switches between blowing and vacuuming, so one machine handles clearing, collecting, and shredding leaves.
Key Specs and How It Works
WORX rates the WG509 at 350 CFM of air volume and 210 MPH of air speed, driven by a 12-amp motor. The air speed can be dialed electronically from about 75 up to 210 MPH, which lets you ease off around flower beds and turn it up on driveways or open lawn. In vacuum mode, debris is pulled through a metal impeller and shredder blade that make up the multi-stage all-metal mulching system, giving a rated 18:1 mulch ratio. That means a bag of leaves is reduced to roughly one eighteenth of its loose volume, so the 1.2-bushel collection bag holds a large amount of shredded material before it needs emptying. The motor spins up to about 15,000 RPM with no load, which is what drives that airflow through the tube.
Strengths
The all-metal impeller is the standout feature at this price, since many competing electric vacuums use plastic that can crack on twigs and acorns. Switching between blow and vacuum modes is done with a flip of a switch rather than swapping tubes, which keeps cleanup quick. Because it is corded, there is no battery to recharge and no runtime limit, so it suits longer fall cleanup sessions. The single-hand design and variable speed make it manageable for detail work, and WORX backs the unit with a 3-year warranty, which is longer than many corded blowers offer.
Watch-Outs
At about 9.3 pounds it is on the heavier side for a single-hand electric unit, and the weight is more noticeable in vacuum mode with a filling bag. Being corded, you are limited by your extension cord reach and need a nearby outlet, which makes it less suited to large or far-flung properties. Like most handheld vacuums, it can clog if you feed it wet, matted leaves too quickly.
Who It Is For
The WG509 fits homeowners with small to medium yards who want one tool for blowing, collecting, and mulching leaves without buying batteries or dealing with gas. If your priority is maximum blow force over a large area, a dedicated high-CFM blower is a better match, but for combined leaf pickup and shredding on a budget the TRIVAC covers all three jobs.
