WORX WG509 TRIVAC Review Canada

Quick verdict: WG509 combines blowing, vacuuming and mulching in a corded tool. Consider it when the work area is within a suitable outdoor power setup and you can manage the collection bag. Its published airflow and reduction ratio do not establish clearing speed or performance with saturated leaves.
Three tools in one body
WG509 is designed to blow leaves into position, vacuum them and reduce their volume before collection. The benefit is fewer separate tools and no battery charging. The compromise is that a combination machine must carry tubes, bag hardware and conversion mechanisms that a dedicated blower does not need.
350 CFM in context
Airflow helps move a broad layer of leaves, but CFM alone does not describe clearing force. Air speed, nozzle shape, working distance and debris moisture all matter. This is better viewed as a capable residential blower-vac than as a direct substitute for the strongest 700+ CFM cordless blowers on wet, embedded leaves.
The 18:1 mulch claim
A published 18:1 ratio is a best-case reduction claim, not a guarantee that eighteen bags of every leaf type become one bag. Dry brittle leaves reduce far more effectively than wet maple leaves, twigs or fibrous debris. The practical advantage is fewer bag-emptying trips and more compact material for composting or disposal.
Corded power: strength and constraint
A cord supplies consistent energy without battery replacement cost or recharge pauses. The extension cord must be outdoor-rated, sized for the current and length, connected to suitable protected power and routed away from the intake. Large or irregular properties can turn cord management into the dominant part of the job.
Bag capacity and working weight
The collection bag reduces cleanup after vacuuming, but every leaf adds weight to the operator. Damp material becomes heavy quickly and can strain the bag attachment. Emptying before the bag is packed solid improves balance and reduces stress on fabric, zipper and connection points.
Wet-leaf limitation
Saturated leaves adhere to turf, bridge across the intake and coat the impeller. Work in thin layers and use blower mode to loosen material first. Stones, sticks, metal, glass and other hard debris should be removed before vacuuming because they can damage the impeller or become hazardous projectiles.
Choose it over STIHL SHA 56 when…
The useful distinction from SHA 56 is the power arrangement: WG509 requires a cord, while SHA 56 requires a compatible battery and charging plan. Walk the route and compare complete purchase costs. Neither arrangement removes bag-emptying, handling or material limits.
Safety and maintenance
Unplug the machine before clearing a blockage or changing modes. Use eye and hearing protection, keep the cord behind the work path and avoid wet electrical connections. Empty and dry the bag after use, clean accumulated debris according to the manual and inspect the cord, plug, tubes and impeller housing regularly.
Evidence and limits
The 350 CFM claim, 18:1 published reduction ratio and corded three-in-one design are documented. Material condition has too much influence to interpret those claims as a standardized result for every Canadian yard.
Bottom line
The WORX WG509 is worth buying for a cord-accessible property that generates regular dry-leaf cleanup and benefits from vacuum collection. It is less convincing for a large yard, heavy saturated leaves or anyone who strongly dislikes managing an extension cord.
