These WORX “Trivac” models – so called because they are both 3-in-1 tools that include a vacuum plus a blower and mulcher – are perfectly suited for routine fall yard maintenance. Professionals will be looking for something more gung-ho and likely gas-powered, but for anyone else, choosing between these two has no bad outcome.
The 509 does a little more but it also costs a little more. Only you can decide if its slightly greater capabilities are worth paying a bit more for. But if you are ready to hand in the rake and spend more time enjoying fall instead of dreading all the outdoor work it generates, read on – you will definitely want one of these machines.
Both machines are corded 12-amp tools that generate wind speeds up to 210 mph, so in this sense they are identical. But the 509 has that higher mulching ratio – 18:1 instead of 16:1. Is this a minor difference? Maybe. But if you’ve ever sat staring at the big chunks in your compost bin wondering when they will ever disintegrate into pieces small enough to spread around your flowers, you might appreciate the 509’s finer mulcher.
The 509 will be slightly more expensive than the 505, but it also does a little bit more. However, both are a 3-in-1 tool and will save you money in the long run over buying three separate tools to do the work of either one of these. We’re calling a tie on price.
Again, these two tools are very similar, but the 509 includes two extra features the 505 does not. The 509 has a simple release button that allows you quickly and easily pop open the tool and clean out any clogs in the mulching blade. Clogs do happen, and users appreciate how easy it is to flip it open and dig out wayward chunks of mulch or large twigs.
The 509 also has variable speed power control. A simple dial on the handle allows you to turn up the wind (or suction) to gale force to move stubborn, wet leaves, but also lets you turn it down to gentle puffs, so you don’t remove all the blooms from your flowers or suck up (or blow away) your mulch. The 505 does have an adjustable air regulator, but it’s not as fine-tuned as the 509’s variable speed feature. The win has to go to the 509.
Although these models appear to be identical in exterior design – and in fact, WORX appears to be using some of the same imagery on the promotional materials for both – there are two differences worth noting. The 509 is slightly heavier, presumably because it has the more aggressive, dual-stage mulcher. It’s less than a pound difference, but something you might notice after carting it around all afternoon. Also, the 509 generated a surprising number of complaints from people struggling to manage the intersection of shoulder strap, shoulder bag, and the tool’s cord. Therefore, for design, the win goes to the 505.

Both models – the WORX Trivac 505 and 509 – are popular with the weekend yard maintenance crowd. Each garners fans for its 3-in-1 abilities that leave rakes gathering dust in the garage and free up hours of time for watching fall football instead of collecting fall leaves. Everyone loves that you can change from blowing to vacuuming with the flip of a switch, a feature of both models.
Neither is gas-powered, and some users lament the lack of blowing and vacuuming power that comes with trading down to electric. But most people are thrilled there is a non-gas option, one that leaves fuel mixing and heavy, one-function machines behind.
Users are happy with the mulching feature on both machines. Anyone who has ever tried to turn a yard of fallen leaves into a tidy pile of mulch finds either machine an enormous time and labor saver. Very few of the 509 users were calling out how fantastic the smaller bits were so the higher mulching ratio of the 509 might not be all that appreciated.
Although you might expect people to rave about the variable speed dial on the 509 – or the fact that it’s missing from the 505 – there’s little to no chatter about this feature. What users do mention is the challenge of getting wet leaves to move, so perhaps the lower wind speeds just aren’t being put to use.
No one likes the included shoulder bag for either model. It’s both too small, requiring frequent emptying, yet too heavy when full. The most satisfied users of both tools have ponied up for the WORX leaf collection system, essentially a long hose that attaches the tool to any large trash can. But those using the shoulder bag on the 509 are adamant it is uncomfortable, and even though the bags appear identical, 505 users are not as consistent in their dislike of its bag and shoulder strap combo.
The 505 gets the job done – puts the leaves where you want them and turns them into a much smaller pile of chopped leaves. It weighs a little less and costs a little less.
The 509 has all the same bells and whistles, and while it weighs more and costs more, it gives slightly more “wind” control and a finer grade of chopped leaves.
Are you willing to pay a little more for super-fine mulch or precise wind speeds? Most users will likely be perfectly happy with the WORX Trivac WG 505 and not miss the perks of the 509 model. It’s a close call, but our vote goes to the 505.
