WORX WG509 TRIVAC Blower, Vacuum and Mulcher review

A corded 3-in-1 for yards where collecting leaves matters

The WORX WG509 is a handheld 120-volt, 12-amp TRIVAC that can blow, vacuum and mulch. Its appeal is not a battery-free way to work anywhere; it is a single corded machine with an alternate bagged collection mode. That suits a homeowner who can keep a suitable outdoor extension cord routed safely and wants to gather dry leaves after pushing them into manageable piles. It is a poor match for a yard where the cord will snag constantly, a cordless requirement is essential, or the buyer expects the blower and vacuum to work at the same time. They are alternate operating modes.

Read the airflow figures as published, not as a field test

WORX lists 350 CFM and an air-speed range of 80–210 mph. Those are useful manufacturer specifications for identifying this product, but they do not promise a clearing time or establish how the blower moves a wet leaf mat. The manual lists 350 CFM as airflow without assigning it to a specific mode or measurement configuration. The finder therefore does not treat 350 CFM as a verified blower-mode maximum for a strict CFM minimum. If a hard blower-mode CFM floor is the reason you are shopping, choose a product whose documentation expressly ties that value to the blower setup rather than assuming the WG509's combined-tool specification answers the question.

For ordinary yard work, the more distinctive specification is the manufacturer-stated 18:1 reduction ratio. WORX describes a two-stage, all-metal impeller and lists the same ratio in the manual. That is a manufacturer claim, not a measured promise about the texture, volume or composting behavior of every batch of leaves. The manual's six-position speed switch gives a way to tune the blower airflow; it is a dial, not a trigger that must be held to maintain a selected speed. There is no separate high-output turbo or boost figure to treat as a second CFM rating.

The bag and package matter as much as the tool body

The exact WG509 page lists one TRIVAC unit and one debris collection bag. The manual rates the bag at 1.2 bushels, also expressed as 42 liters. That is a useful comparison point if a 40-liter minimum is enough; it is not a promise that the bag will hold a particular number of bags of unmulched leaves. A 45-liter minimum is not documented for this package. The model chart in the manual also lists WG509.1 and WG509.2 with different accessories: the .1 entry adds a WA4054.1 high-capacity universal collection system, while the .2 entry lists two bags. Those suffixes are not interchangeable with the base WG509 carton; verify the full model number and actual package before assuming an accessory is included.

WORX markets quick conversion, while the manual shows the blower/vacuum tube assembly, a mode selector, a quick-release bag collar and an on/off switch. Use the correct assembled mode and included bag rather than trying to collect debris while blowing. If bagging is not part of your routine, a blower-only model avoids carrying and emptying the extra collection equipment. If you need battery power, compare cordless vacuum/mulchers instead of treating a corded tool as a battery-kit substitute.

Plan the cord route before choosing it

This is a 12-amp corded tool, so access to an outdoor-rated extension cord and a practical route around beds, gates and walkways are part of the ownership plan. The manual's cord table gives wire gauges by cord length and says not to use more than 150 feet; it also warns against running a cord through standing water or wet grass. Keep it in view and out of the tube path. That operational constraint can outweigh the appeal of a listed air-speed number on a lot with obstacles or distant outlets. The manufacturer says not to vacuum wet leaves and cautions against hard debris such as nails, bolts, wires, staples and rocks. Keep the vacuum tube above the material rather than force-feeding a pile into the impeller.

The manual describes residential outdoor use. It also says to wait for moving parts to stop, unplug the tool and then clear a clog or service it. The bag must be installed and zipped during vacuuming; inspect it for wear, since a worn bag can let small debris through. These are practical limits of an impeller-based collector, not reasons to use it for gravel, construction waste or heavy brush.

Weight and noise are not settled buying filters

The exact product page and manual both give a 9.3-pound machine weight, but neither defines whether the number includes the working tube or bag configuration. No ready-to-use or vacuum-mode mass, 50-foot sound rating or blow-force figure is established in the sources used here. The weight should not be entered as a bare-tool or complete operating weight, and the quietness of any one yard cannot be predicted from a missing rating. If your essential limit is a complete carry weight or a specified sound ceiling, the WG509 cannot be confirmed against it from these records.

Choose between the related models on documented differences

The WG505 shares the 12-amp, 350-CFM and 80–210-mph headline numbers and a 1.2-bushel bag, but its manual gives a 16:1 reduction ratio rather than 18:1, and its speed-control description conflicts across the current page and manual. The WG509 is the clearer pick if the 18:1 claim and documented six-position speed dial matter. The WG518 is another corded WORX vac/mulcher with a 400-CFM figure, but its sources also leave blower-mode CFM unseparated; a larger printed number is not a confirmed blower-mode advantage. For a cordless collection plan, compare a battery model such as EGO's LV5005 and check the exact battery package. The WG509 makes most sense when the cord is manageable, bagged dry-leaf pickup is useful, and its unknown operating weight or mode-specific CFM is not an essential pass/fail requirement.
