WORX WG505 TRIVAC 3-in-1 Leaf Blower, Vacuum and Mulcher: specs and fit

The WORX WG505 TRIVAC is a 12 amp electric tool that works as a leaf blower, a leaf vacuum and a mulcher. Instead of raking leaves into piles and stuffing them into bags, you can blow them into a heap, or suck them up and shred them on the spot. This page explains what the figures mean and what to think about before choosing one.

Three jobs in one tool

WORX says the WG505 switches from blower to vacuum in moments and without extra tools. In blower mode, it moves leaves and light debris along paths, patios and lawns. In vacuum mode, leaves are pulled in through the tube, shredded and sent into the collection bag. That saves you owning and storing two separate machines, which matters in a small shed or garage.

What 350 CFM and 210 MPH mean

Two numbers describe blower performance. CFM (cubic feet per minute) is the volume of air moved; MPH is the speed of that air at the nozzle. WORX rates the WG505 at up to 350 CFM and 210 MPH. In general, higher air speed helps lift stuck, damp or flattened leaves, while higher volume helps push a wide pile along. Both figures are maximums, usually measured at full speed with the nozzle fitted.

The listing also describes variable speed control. A lower setting is typically better for sweeping light debris off a deck or from around plants, and full power for clearing a lawn.

The metal impeller and mulching ratio

Inside a leaf vacuum, an impeller spins to pull in leaves and cut them up. The WG505 uses a two-stage metal impeller. WORX says it mulches leaves at a 16:1 ratio, so 16 bags of leaves become one. Shredded leaves take up far less room, so you can empty the bag less often. Mulched leaves are also commonly used as a garden mulch or added to a compost pile.

Metal impellers are generally sturdier than plastic ones when a twig or small stone gets pulled in, though it is still wise to clear large sticks and stones first.

The collection bag

The bag holds 1.2 bushels of mulched material. It comes with a shoulder strap, so it can be worn like a satchel and the tool operated with one hand. WORX says the tool is designed to be carried comfortably while running. The whole unit weighs 9.7 lb, according to the listing, and measures 14.1 x 3.2 x 6.3 inches (about 36 x 8 x 16 cm) in the dimensions given.

Reaching tight spots

WORX says the tube design helps in corners and narrow areas, and lets you blow or vacuum under patio or lawn furniture. A slim tube is useful where a bulkier blower won't fit, such as along a fence line or beneath a bench.

Who it suits

It suits owners of small to medium yards who face seasonal leaf fall and want blowing, vacuuming and mulching in one machine. As an electric tool, it generally starts at the push of a trigger and needs no fuel mixing. It is less suited to very large properties or places far from a power outlet.

What to check before you buy

• Power supply: it is a 12 amp electric model, so check how far you need to reach and what extension cord the manual recommends.
• Yard size: a 1.2 bushel bag is handy for small and medium lawns; larger areas mean more emptying.
• Noise: blowers are loud. Check local hours for use, and wear hearing protection as the manual advises.
• Switching modes: read the manual on how to change between blowing and vacuuming, and on clearing blockages.
• Debris type: wet leaves, twigs and pine needles behave differently from dry leaves, so check what the manual says the vacuum can handle.
• In the box: the listing includes the WG505 blower and a collection bag.
