WORX WG584.9 40V Max tool-only brushless blower review

WG584.9 is the body-only option, not the ready-to-run kit

WORX identifies WG584.9 as a separate 40V Max, brushless handheld TURBINE blower configuration. The U.S. product page says batteries and charger are not included, and its box list contains the blower rather than a full power kit. The difference from WG584 is consequential: the machine requires two 20V Max Power Share batteries installed at the same time, but the .9 package supplies none. This is a sensible choice only when you already own two compatible packs and a charger, or deliberately plan to purchase that power setup separately. Owning just one 20V battery is not enough to operate it. The WG584.1 is another separate package, with two 4.0 Ah batteries and a dual charger listed by WORX; do not treat the tool-only .9 as that bundle.

What the airflow numbers say—and what they do not

The product heading says 430 CFM and 90 mph. The detailed page table and linked WG584M manual list three airflow settings and a Turbo setting: 300, 350, 390 and 470 CFM; 60, 69, 80 and 95 mph. The manual names both WG584 and WG584.9 and presents the values by setting. These are maker specifications, not independent measurements, and the 470-CFM and 95-mph maxima are separate output modes rather than simultaneous promises. A shopper who needs a documented Turbo mode can consider the .9; one who requires vacuuming or a leaf bag should rule it out because WORX explicitly says the blower has no vacuum or mulching function. If a minimum above the 470-CFM table value is essential, this configuration does not qualify. The lower headline ratings and higher detailed figures are a source discrepancy, so avoid treating the maximum as a guaranteed yard result.

Its 40V label means two batteries are needed

WORX describes the tool as a 40V Max system powered by two 20V Max packs. Its FAQ says 40V Power Share tools will not run with one battery installed, and the manual repeats that two packs must be in place. That requirement is especially important for a tool-only purchase: battery compatibility does not mean the batteries are included, and buying one compatible pack does not complete the operating setup. The shared platform can be attractive to an existing Power Share owner, but check that the available pair is usable together and that charging equipment is on hand. A numeric runtime is not supplied for a defined battery pair and workload on this exact .9 package, so do not infer minutes from another kit’s capacity or advertised claim.

Separate bare-tool weight from weight in use

The WG584M table lists 5.5 lb for WG584.9 without a battery. That is a useful bare-tool reference, not the weight you carry with the two required batteries installed. The exact .9 page does not provide a complete operating-weight figure, and the 7.3-lb value in the same manual belongs to the WG584 battery-included column. Neither value establishes the ready-to-use mass of the tool with the buyer’s two packs. If your advanced choice is a strict bare-tool limit of six pounds, the documented 5.5-lb entry supports that condition. If the limit applies to the complete operating setup, the available evidence cannot confirm a pass. The manual illustration used with this page is shared WG584-series line art; its pictured battery arrangement is not evidence of included accessories.

Practical fit for existing Power Share owners

As a handheld blower, the WG584.9 can move loose yard debris with three speed settings and a Turbo button, while its brushless motor distinguishes it from simpler brushed tools. The manual describes residential outdoor use, tube assembly and battery-status lights; it also emphasizes eye and hearing protection. For smaller routine cleanup on a single 20V pack, the WG547 is a more straightforward system. For a buyer who wants batteries and charger in the box, compare the base WG584 and its unresolved battery-capacity/charger details or the WG584.1 with its page-listed two 4.0 Ah packs. For collecting rather than blowing, the WG505 and WG509 have separate vacuum/mulch functions that this model lacks. A larger-output model such as the WG585 is also a distinct two-battery product, not a source for WG584.9 package facts.

How choices change its fit

The ordinary “tool-only” answer is yes for WG584.9 and no for the full WG584 kit. Requiring two batteries in the package or a supplied charger excludes the .9, even though it needs two packs to run. A 470-CFM Turbo minimum can fit the manual’s top setting; a requirement above that should reject it. Selecting a blower-only tool keeps it eligible, while requiring leaf vacuuming and mulching removes it. The advanced bare-tool weight option can use the 5.5-lb manual figure, but a maximum operating-weight choice remains unknown because the pair of batteries changes the real carry weight and no complete value is stated. Unknown should not be interpreted as light enough.

Bottom line

WG584.9 is a package decision first: it avoids duplicating a battery kit only for someone who already has the compatible two-pack setup. It shares the family’s handheld brushless blower, three speeds and Turbo, but provides no batteries, charger, vacuum, mulcher or bag. The manual’s 5.5-lb bare-tool figure is not an in-use weight; published airflow values also differ between the page headline and detailed table. If you need a ready-to-work purchase, compare a kit instead. If you already own the required pair and want only the blower body, the .9 is the configuration to assess—while keeping its exact gallery photo and complete running weight unresolved.
