WORX WG512 Trivac 3-in-1 Leaf Blower, Mulcher and Vacuum: specs and uses

The WORX WG512 Trivac is a corded electric tool that does three autumn jobs: blowing leaves, vacuuming them up and mulching them. Switching between modes takes a turn of a dial, with no tube swap and no tools. It aims to cut down both the raking and the number of bags you drag to the kerb.

Three tools in one body

In blower mode, air leaves through a wide-mouth tube. In vacuum mode, leaves are pulled in and passed to a mulcher, then collected in the bag. WORX says its articulating design changes modes with one turn of a dial and that no accessories need swapping. Fewer parts to keep track of is one practical benefit of a combination tool.

What 600 CFM means in practice

CFM, cubic feet per minute, measures the volume of air a blower moves. Speed (miles per hour) shows how fast that air leaves the nozzle. Both matter: volume shifts piles of leaves, while speed lifts wet or stuck debris. WORX rates the Trivac at 600 CFM, with up to 70 mph on the higher of its two speeds. The lower speed is meant for pavement and tight corners, and the higher one for open lawn. A wide stream usually means fewer passes.

The mulcher and the 16:1 ratio

The listing describes a metal impeller with a shredder blade that cuts in two stages. WORX quotes a 16:1 mulch ratio, meaning that about 16 bags' worth of leaves reduce to one. Actual reduction varies with how dry and how fine the material is. Smaller pieces break down faster in a compost heap or can be used as garden mulch. The 1.4-bushel bag detaches quickly for emptying.

Weight and handling

WORX describes the tool as one-handed in operation, with an ergonomic design that funnels the airflow; the listing gives 6.6 lb for the unit and about 9 lb in its text. The motor is rated at 12 amps with a no-load speed of 16,500 per minute. The short power cord has a retainer for an extension cord, so a snagged cord is less likely to pull apart.

Corded versus gas

An electric motor typically runs quieter than a petrol engine and has no fuel to mix. The trade-off is the cord: your reach is limited by the extension cord you attach, which should be outdoor-rated and of a suitable gauge.

Who it suits

It suits owners of small to medium yards with deciduous trees who want one tool for clearing and collecting leaves. Those with very large properties may prefer a cordless or petrol machine, as the cord limits range.

What to check before you buy

• Reach: measure the distance from an outlet to the farthest corner of your yard.
• Extension cord: use a suitable outdoor-rated cord.
• Storage: the tool is about 35.5 inches (90 cm) long, plus the bag.
• Debris: read the manual on what can and cannot be vacuumed.
• Bag size: a 1.4-bushel bag fills quickly in heavy fall; plan to empty it often.
• Protection: follow the manual's guidance on eye and hearing protection.

The short version

• A 12-amp corded tool that works as blower, vacuum and mulcher.
• 600 CFM, two speeds, and up to 70 mph airflow.
• 16:1 mulch ratio with a metal impeller; 1.4-bushel quick-release bag.
• One-handed design with an extension cord retainer.
• Best matched to small and medium yards within reach of an outlet.
