Best WORX Trivac 40V 3-in-1 Cordless Leaf Blower

Q: Does the battery system work with other WORX tools?

The listing says the PowerShare system lets you combine 20V batteries to power WORX tools across 20V, 40V and 80V tools. It does not say which packs this unit needs, so confirm that with the seller.

If you are searching for the best worx trivac 40v 3-in-1 cordless leaf blower, the first question is the battery. The WORX WG588.9 is listed with the battery and charger not included, and the listing names the PowerShare battery system. The listing describes one unit that blows, vacuums and mulches, with 600 CFM of airflow, a 100 MPH top air speed and a 20:1 mulch ratio. Runtime is given as up to 49 minutes of blowing and 35 minutes of vacuuming per charge, but the battery behind that figure is not named. This page sets out what the listing says and what it leaves open.

Quick answer

The listing describes a 40V cordless leaf blower, vacuum and mulcher with 600 CFM of airflow, a 100 MPH top air speed and a 20:1 mulch ratio.
The battery and charger are not included. The listing says PowerShare works by combining 20V batteries to power 40V tools, but it does not say how many packs this unit needs.
The listing states up to 49 minutes of blow time and 35 minutes of vacuum time per charge. It does not name the battery behind those figures.
Buy it only if you already own WORX batteries and a charger, and the seller confirms how many packs the unit needs. Check the extra bag offer before you order too.

Who it suits

This unit fits a specific set of buyers. It makes sense when most of these points are true for you. If all you need is a blower, the vacuum and mulch functions are the main reason to choose this model over a blower-only unit, so ask yourself whether you will use them before you pay for them.

You already own WORX batteries and a charger, or you are ready to buy them, because the listing includes neither.
You want one tube that blows and vacuums, and you want to switch between them without tools. The listing says “Simply rotate the handle to switch modes seamlessly.”
You want a mulching function. The listing describes a 20:1 mulch ratio and says the impellers deliver “a high mulch ratio for fine nutrient-rich leaf mulch and fewer bin empties.”
Your yard is the size the seller describes. The listing says the unit is “Great for small and medium yards,” which is the seller’s view and not a coverage figure.

If the battery question is your main concern, our post on a WORX hedge trimmer battery and charger covers the WORX battery and charger side from a different tool, and it may answer questions about packs and chargers.

Skip it if

You need the battery and charger in the box. The listing item highlight says “Battery & Charger Not Included.”
You need a runtime figure tied to a battery you can name. The listing’s figures are per charge, and no pack is named.
You only need to shred leaves on the lawn. The Penn State Extension page says “For shredding leaves, a lawn mower is the only tool needed.”
You need a warranty before you buy. The listing does not state one.

Three jobs, one handle

The listing puts the design in one line, “3-IN-1 TRIVAC INTELLIGENT DESIGN,” and then describes how the modes change. It says “Simply rotate the handle to switch modes seamlessly,” and that the tube needs no nozzle removal. The listing also describes a safety feature: “High-precision hall sensors prevent motor activation during mode switching and internal cleaning.” That is the seller’s description of the sensors, and the sources do not show how they work in use.

The speed and airflow figures sit in the item highlight: “Battery & Charger Not Included, 600 CFM & 100 MPH, 20:1 Mulching Ratio, Brushless, 3-Speed Control, PowerShare.” The listing also says “This leaf blower features 3-speed control, putting the power in your hands.” It does not say how the 600 CFM and 100 MPH figures change between blowing and vacuuming, or at each speed step.

The mulch claim is the most detailed. The listing calls the impellers “robust triple-layer metal impellers” and promises “fewer bin empties.” The Penn State Extension page offers a useful background point: “Shredded leaves decay much more quickly than whole leaves.” That page describes shredding with a mower, though, not with a blower. The listing does not say how the 20:1 ratio was reached, what leaves it applies to, or whether it holds for wet leaves.

Mistakes to avoid

Buying without a battery plan. The listing says the battery and charger are not included, and it does not say how many 20V packs the 40V unit needs.
Counting on the extra bag. The listing says the extra bag is “for the first 3,000 units.” Ask the seller whether your unit qualifies before you rely on it.
Blocking the intake. The OSU Extension column says “Be sure to keep the air intake clean of lawn debris to ensure the motor doesn’t overheat.” Check the intake before each job.
Pointing the discharge at people. The same column says “The primary hazard of a leaf blower is that it can propel small rocks and sticks, nuts and other debris toward bystanders.”
Skipping eye and ear protection. The Virginia Tech publication says “Wear full eye and ear protection when operating powered hand tools.”

Buying checklist

Confirm the battery count. Ask the seller how many WORX packs the 40V unit needs, because the listing does not say.
Confirm the charger. The listing says the charger is not included.
Check the extra bag. The listing offers an extra bag for the first 3,000 units only.
Ask about the 160 watt-hour field. Confirm which battery it describes, since the listing does not say.
Decide whether you need the mulch function. If you only want to blow, the vacuum and mulch features add little to the job.
Ask about the warranty, which the listing does not state.
Plan for eye and ear protection, and keep bystanders out of the discharge path.

What the listing does not say

The battery question is the largest gap. The listing says the battery and charger are not included, and it describes the PowerShare system as one where “Combine 20V batteries to power any WORX tools” works across 20V, 40V and 80V tools. It does not name the pack count or the pack size for this 40V unit. A buyer with an older WORX pack should confirm the fit with the seller before buying.

The runtime line is the second gap. The listing states “Up to 49 min blow and 35 min vacuum runtime per charge.” It does not name the battery used for that test, and it gives no runtime for a smaller pack. The wattage field of 160 watt-hours sits in the same listing, but the listing does not say which battery that figure describes, so it cannot be used to compare packs.

The extra bag is the third gap. The listing says the extra bag comes with “(1) extra bag for the first 3,000 units.” It does not say how many units remain, and it does not say whether the offer is still running when you order. The listing also gives no warranty length. The manufacturer is named as “Positec Technology (China) Co., Ltd,” but we found no WORX product page for model WG588.9 to check the specifications against.

For a second WORX product that shares the battery question, our Worx hedge trimmer battery and charger post is a useful reference, and our Black and Decker cordless leaf vacuum post covers a different vacuum design for buyers who want only a vacuum.

How we chose

This post covers one product: ASIN B0HDY274C3, the WORX Trivac 40V 3-in-1 Cordless Leaf Blower/Vacuum/Mulcher, model WG588.9. It is in the post because the search phrase names this exact model family. The product record is a single yard tool that blows, vacuums and mulches, and it is battery powered. It is not gas-powered, it is not an attachment or a part, and it is not a manual sweeper.

The listing title and specifications come from a stored scan record checked on 2026-10-23. We searched for a manufacturer product page for model WG588.9 and found none. The search results showed sibling model numbers and retailer pages, and we did not use any of them for facts. The safety guidance comes from two university extension pages, and the leaf shredding background comes from a third, all opened on 2026-10-22. We did not rank this unit against other leaf blowers, so this post makes no ranking claim.

What we could not verify

Runtime with a named battery. The figures in the listing do not identify the pack behind them.
Whether the battery charge indicator reads correctly with every PowerShare pack. The listing names the indicator but does not list which packs it works with.
Whether the WG588.9 has a WORX product page with matching specifications. We could not find one.
How the 600 CFM and 100 MPH figures apply in each mode and at each speed setting.
How the 20:1 mulch ratio applies to wet leaves or mixed debris. The listing gives the ratio without conditions.
What the 160 watt-hour field describes, and whether the extra bag offer is still open.
Warranty length. The listing does not state one.

FAQ

Does the WORX Trivac 40V leaf blower include a battery?

No. The listing says the battery and charger are not included. It does not say how many 20V PowerShare packs the 40V unit needs.

How long does it run on a charge?

Up to 49 minutes of blowing and 35 minutes of vacuuming per charge is the listing’s figure. The listing does not say which battery was used, so the runtime with your own pack is not stated.

Does it come with a leaf bag, and is there an extra one?

The listing includes a leaf collection bag. It also offers an extra bag for the first 3,000 units. The listing does not say how many of those units remain, so ask the seller before you rely on the extra bag.

Can it mulch leaves?

The listing describes a 20:1 mulch ratio and says the impellers deliver a high mulch ratio for fine leaf mulch and fewer bin empties. Neither source we opened explains how that figure was reached or which leaves it applies to.

Does the battery system work with other WORX tools?

The listing says the PowerShare system lets you “Combine 20V batteries to power any WORX tools” across 20V, 40V and 80V tools. It does not say which packs this unit needs, so confirm that with the seller.

Is there a warranty on this model?

The listing does not state a warranty. Confirm the terms with the seller before you buy.

Bottom line

Buy this unit only if you already own WORX batteries and a charger, and the seller confirms in writing how many packs the 40V unit needs. If you do not, skip it.
