WORX WG584 40V Max brushless handheld blower kit review

The WG584 is the kit version of a shared 40V blower

WORX lists the WG584 as a 40V Max handheld, brushless TURBINE blower supplied with batteries and a charger. Its neighboring model codes matter: WG584.9 is a tool-only configuration, while WG584.1 is a separate kit page that specifies two 4.0 Ah batteries. Do not merge their package contents. For the base WG584, the current U.S. product page says the box has two 20V Power Share batteries and a dual-port charger; its FAQ names 2.0 Ah packs. The linked WG584M manual has a different package table: it names a 2.5 Ah WA3577 battery and WA3875 charger and lists one battery in its accessory row. The actual capacity and exact included charger mapping are therefore not consistent across these sources. If pack capacity or charger model is an essential purchase condition, confirm the exact carton listing rather than assuming that a sibling package supplies it.

Read the airflow figures as mode-specific claims

The product heading uses 430 CFM and 90 mph, while the specification table and WG584M manual describe three settings plus Turbo: 300, 350, 390 and 470 CFM, paired with 60, 69, 80 and 95 mph. These are manufacturer ratings, not a measured clearing time, and the volume and speed figures belong to separate settings. The meaningful practical choice is between lower settings for closer work and the boosted stream for moving larger piles or material that is less willing to shift. If your decision depends on a hard minimum above the 430-CFM headline, recognize that the detailed table gives a higher Turbo maximum; the page does not explain why the headline and table differ. Our comparison treats 470 CFM as the documented manual/table maximum while preserving the discrepancy, not as an independent performance guarantee.

Two 20V packs are part of the operating plan

This 40V Max system is formed from two 20V Max Power Share batteries. WORX says the 40V tools will not run with only one pack installed, and the manual says both batteries should be charged together. That is a useful distinction from a lighter single-pack blower: the WG584 gives a two-battery platform, but it also means the blower needs a matched pair ready for each session. The included kit is the more convenient starting point if you do not already own compatible packs. Buyers who already have two suitable batteries and a charger may prefer the WG584.9 body-only package, while shoppers who want the page-confirmed 4.0 Ah pair should compare the WG584.1 listing instead. The base kit’s own manual/page battery-capacity conflict prevents a confident capacity threshold match.

Weight is not a clean operating-weight promise

WORX publishes 7.3 lb for the WG584, and the manual places that value in a “battery pack included” row. Neither wording makes the measurement setup fully clear for a machine that requires two packs, so a strict ready-to-use weight ceiling should not treat 7.3 lb as a verified two-battery operating weight. The manual’s other column gives 5.5 lb without a battery for WG584.9, but that bare-tool number belongs to the sibling SKU and cannot be substituted for the WG584 kit’s complete weight. The machine is handheld and includes a battery indicator; it is not a backpack system or a collection tool. The manual’s line drawing is shown here only as a shared-family illustration, not proof of which batteries are in the box.

Where the WG584 fits—and where it does not

WORX describes the blower for residential outdoor debris and mentions driveways, sidewalks, patios, decks and yards. Its three-speed-plus-Turbo control gives a household more than one air setting, and the brushless motor is a real distinction from a lower-output brushed design. Still, no numeric runtime under a stated yard load was established for the base kit, so battery capacity alone should not be turned into a minutes promise. It is a blower only: the manufacturer says it has no vacuum or mulching function, and no collection bag is listed. If leaf pickup and bagging are essential, a dedicated blower-vac such as the already reviewed WG505 or WG509 is a better functional match. If you need a single 20V pack, a smaller single-battery model such as the WG547 is the more appropriate system; if the higher LeafJet output is the priority, compare the distinct WG585 kit and its two-pack requirements.

How the questionnaire should change the shortlist

Selecting a handheld battery blower with two included batteries and a charger favors the WG584 kit over WG584.9. Choosing tool-only reverses that package fit. A minimum of 470 CFM can match the documented Turbo table value, but raising the threshold above 470 should remove it; the 430-CFM headline remains a material caveat for shoppers who insist on one unambiguous rating. A vacuum-and-mulch requirement excludes it regardless of airflow. A strict maximum ready-to-use weight also cannot be confirmed from the available weight basis. These choices are more useful than treating “40V” or a single maximum number as a complete description.

Bottom line

The WG584 is the sensible configuration when you want the base 40V brushless blower package rather than buying a bare tool and arranging batteries separately. Its strengths are a handheld format, three settings plus Turbo, a simultaneous two-pack operating plan and the documented 470-CFM/95-mph boost table. Its limits are just as important: package capacity and charger details conflict between the exact page and linked manual, the headline output differs from the technical table, complete operating weight is not established, and there is no leaf collection. Choose it for a blower-only job where those tradeoffs are acceptable—not as a guaranteed runtime, weight or yard-clearing result.
