Worx Vs Black and Decker Leaf Vacuum: Which One Should You Buy?

If you’re comparing the worx vs black and decker leaf vacuum options, the short answer is this: choose the WORX WG509 for its 18:1 leaf reduction and 42-liter collection bag; choose the BLACK+DECKER if you want stronger maximum airflow and a backpack-style collection bag.

The BLACK+DECKER reaches up to 400 CFM and 250 MPH with POWERBOOST, compared with the WORX’s maximum 350 CFM and 210 MPH. Those figures describe different parts of airflow, so neither number alone tells you how a vacuum will feel during every task.

Both are corded three-in-one tools that can blow, vacuum, and mulch. The practical differences are how they handle leaf collection, how much detail is provided about bag capacity, and whether your cleanup calls for controlled everyday work or extra blowing power on demand.

Below, I’ll compare their airflow, collection systems, controls, and everyday trade-offs, then match each model to the kind of yard and cleanup routine it suits. The right pick depends less on the biggest number and more on what you need to move, collect, and empty.

Worx Vs Black and Decker Leaf Vacuum Detailed Comparison

The WORX WG509 and the BLACK+DECKER three-in-one both combine blowing, vacuuming, and mulching in a corded tool. That shared setup makes them relevant for clearing patios, walkways, lawn edges, and other places where you want to gather leaves rather than only push them around.

The biggest measurable airflow advantage goes to BLACK+DECKER: its POWERBOOST button brings maximum output up to 400 CFM and 250 MPH. The WG509 reaches up to 350 CFM and 210 MPH, and offers variable-speed control for choosing lower or higher airflow.

That difference matters most when you’re moving loose leaves across a larger open area or need a burst of blowing power. For vacuuming, though, maximum blower output shouldn’t be your only deciding point; collection capacity, bag handling, and how easily the tube moves through a pile can matter just as much.

WORX gives you a clearly stated 42-liter collection bag and an 18:1 mulch ratio. That reduction means a large volume of leaves can be shredded into a smaller volume for collection, disposal, or composting. BLACK+DECKER instead highlights a backpack bag with up to twice the bag capacity, a wide opening, and a zipper-free design.

Those capacity descriptions aren’t directly comparable: one gives a volume in liters, while the other describes its backpack bag relative to a standard bag. If you need to estimate how often you’ll stop to empty it, look for a specific capacity for the exact BLACK+DECKER version you’re considering rather than assuming it holds more than the WORX.

For a yard where vacuuming and reducing leaf volume are the priority, WORX has the clearer collection numbers. For someone who expects to wear the bag while gathering leaves and values a wide, zipper-free emptying opening, BLACK+DECKER has a more clearly described carrying and emptying setup.

Key Differences That Matter

Maximum airflow versus adjustable control

BLACK+DECKER’s 400 CFM and 250 MPH maximums are higher than the WORX’s 350 CFM and 210 MPH maximums. Its POWERBOOST button gives you an on-demand increase, which may help when a routine pass isn’t moving a stubborn patch or a larger pile.

The WG509 takes a different approach with variable-speed control. You can dial airflow down for more controlled cleanup or turn it up for bigger piles and open areas. That’s useful around places where you want to avoid sending leaves back across a path you’ve already cleared.

Airflow ratings don’t guarantee a particular result on every surface or with every kind of debris. The practical question is whether you want a higher maximum with a boost button or a variable-speed setting that lets you select a lower output more deliberately.

Collection bag and carrying style

WORX specifies a 42-liter collection bag. That gives you a concrete figure to use when thinking about collection volume, though how often you empty it will still depend on the amount and condition of the leaves you pick up.

BLACK+DECKER supplies a backpack-style bag described as having up to twice the capacity. Its wide opening and zipper-free construction are intended to make emptying more straightforward, while the backpack format puts the collection bag on your back as you work.

Neither description provides a like-for-like capacity comparison. Don’t treat “up to twice the capacity” as a measurement against the WORX’s 42 liters; it doesn’t establish an exact volume relative to that bag. If stopping to empty is a major concern, verify the specific bag’s capacity before choosing.

Mulching and reducing the pile

The WORX has a stated 18:1 mulch ratio. In practical terms, its mulching system is designed to reduce leaf volume substantially, so collected material takes up less room than the unprocessed leaves did.

BLACK+DECKER is also described as a mulcher, but no mulch ratio is specified here. That means you can compare the basic function—both offer mulching—but you can’t make a fair numerical comparison of how much each reduces leaf volume.

If you plan to bag leaves for disposal or want a smaller pile for composting, the WORX’s stated ratio is a useful planning point. If mulching is secondary and you care more about the backpack bag or boosted airflow, BLACK+DECKER may still fit; just don’t assume its reduction ratio matches the WORX’s.

Vacuum maneuverability and mode changes

The BLACK+DECKER includes a Flexi-Tube for maneuverability while vacuuming leaves and debris. That detail may appeal if you want more freedom to guide the vacuum tube around a pile without shifting the whole tool as much.

WORX emphasizes switching between blowing and vacuuming with a flip of a switch or lever, without tools. That can make a mixed cleanup less fussy when you want to blow leaves out of a tight spot, then collect them nearby.

Both models convert among blower, vacuum, and mulcher functions, but the verified details focus on different conveniences. One highlights a flexible vacuum tube; the other highlights tool-free mode conversion. Pick based on which part of the job you expect to change or adjust most often.

Performance, Features, and Everyday Use

Because both tools are corded, you won’t need to pause a yard cleanup to recharge a battery. You will need to work within the reach of the cord and a suitable outdoor power connection, so consider the layout of your yard before buying. A long route around the house may make cord management more noticeable than it would be on a small patio.

The WORX’s variable speed is a practical fit for moving between small, controlled areas and open sections of yard. Lower airflow can help you keep a cleanup contained, while higher airflow gives you more push for a larger spread of leaves. Its 18:1 mulching ratio and 42-liter bag also make the collection side easier to assess in advance.

BLACK+DECKER’s POWERBOOST button offers a different sort of control: access to a higher maximum when you want it. If your cleanup usually involves shifting leaves over a lawn or across a driveway, the higher stated airflow may be appealing. It also converts into a corded blower, vacuum, or mulcher, so you can use the function that fits the task.

Think about the sequence of your cleanup, not just the tool’s top speed. If you blow leaves away from a doorway, then vacuum the pile, quick mode changes may matter more than maximum output. If the leaves are already gathered and you’ll spend most of your time vacuuming, bag design and tube handling deserve more attention.

For bag handling, the differences are concrete but not perfectly matched. The WORX has a 42-liter collection bag; BLACK+DECKER’s backpack bag is described as offering up to twice the capacity, with a wide opening and no zipper. The backpack format may suit someone who prefers to carry the collection bag while moving, while the WORX’s stated volume is helpful for estimating capacity.

Emptying a bag can be an irritating part of the job, especially when you’re making repeated trips. BLACK+DECKER’s wide opening and zipper-free construction are meant to simplify that step. The WORX’s 18:1 reduction may help limit the volume of mulched leaves, but no specific emptying method is stated for its bag.

Neither set of specifications gives a direct weight comparison, so don’t assume one will feel lighter to carry. BLACK+DECKER’s backpack bag is a clear difference in carrying format, but the complete tool’s weight and how it feels during use are separate questions. If comfort is a deciding factor, check the full tool weight and consider whether you prefer a backpack collection bag.

It’s also worth separating blower performance from vacuum performance. The BLACK+DECKER’s higher CFM and MPH figures are blower ratings; they don’t establish that it collects leaves faster or reduces them more than the WORX. WORX’s 18:1 ratio is about mulching, not a guarantee of a particular pickup speed.

For both tools, match the job to the right mode. Use blowing to gather loose debris into a more manageable area, then switch to vacuuming where collecting makes sense. If you mainly need to clear a large open space and already have a way to collect the leaves, the blowing mode may get more use; if you want one tool to gather and mulch them, bag and mulching details should weigh heavily.

Pros and Cons

Which One Should You Buy?

Choose the WORX WG509 if you want a leaf vacuum with clearly stated collection and mulching figures. The 42-liter bag gives you a concrete capacity to consider, and the 18:1 ratio makes it the more straightforward choice if reducing the volume of collected leaves is high on your list.

It’s also a sensible match if you expect to switch between blowing and vacuuming during the same cleanup. The tool-free mode change and variable-speed control are useful for moving between a tight area—such as a walkway edge—and a wider patch where stronger airflow is more appropriate.

Who Should Skip This: Skip the WORX if your main priority is the highest stated blower output of these two; BLACK+DECKER reaches higher maximum CFM and MPH figures. Also look elsewhere if a corded tool won’t suit the distances you need to cover, since the WG509 is designed for corded use.

Choose the BLACK+DECKER if you value higher maximum airflow, an on-demand POWERBOOST button, and a backpack-style collection bag. The wide, zipper-free opening may also suit you if you want a bag that’s designed for easier emptying, while the Flexi-Tube is a specific convenience for guiding the vacuum during collection.

Its capacity description may be appealing, but don’t make your decision on “up to twice” alone if you need a reliable estimate of how much it holds. That wording doesn’t give a direct comparison to the WORX’s 42-liter bag, and the two figures shouldn’t be treated as equivalent measurements.

Who Should Skip This: Skip the BLACK+DECKER if a documented mulch ratio is essential to your decision; WORX provides an 18:1 figure, while no ratio is specified for this model. It may also be the wrong fit if you need a cordless cleanup tool or want an exact bag volume before choosing.

Choosing by blower numbers alone can lead to frustration if your real bottleneck is vacuuming and emptying. On the other hand, focusing only on mulch ratio can leave you overlooking a higher maximum airflow or a backpack bag that better fits how you move around the yard.
