Most leaf blower attachments fall into one of two camps: OEM parts engineered for a specific brand and model, and universal accessories built to clamp onto whatever nozzle you have. The difference matters more than the marketing suggests, a universal kit that technically "fits" can still underperform if your blower's nozzle diameter or airflow is wrong for it. We will flag that throughout.
The five attachment types
1Nozzles: flat vs. round
The nozzle is the single most useful attachment because it changes the shape of your airflow, and shape decides what kind of debris you can move. Almost every brand sells interchangeable nozzles, and many blowers ship with more than one.
Round (concentrator) nozzles
A round nozzle keeps the air volume high and the stream wide. STIHL ships this as the standard nozzle on most of its blowers because it covers more ground and is ideal for loose debris that is not stuck to the surface, think dry leaves across a lawn or driveway.
Flat nozzles
A flat nozzle squeezes the same air through a narrow slit, trading volume for speed. The higher MPH is what lets you peel wet, matted leaves off pavement or flip clippings that a round nozzle just slides over. If you fight wet, stuck-on material often, a flat nozzle becomes the one you reach for.
More restriction is not always better. Bolt a tight concentrator onto a low-powered blower and the backpressure can actually reduce performance rather than improve it. Match the nozzle to the airflow your blower already makes, not to the biggest number on the package.
Real models
Nozzle fitment is brand-specific, so buy for your platform. On the EGO 56V line, the AN6000F (flat) and AN6000R (round) fit the LB5800, LB5804, LB6150, LB6151, LB6500, LB6504, and LBX6000 blowers; EGO also bundles them in the ANC5800 nozzle set. Greenworks sells matching flat and round nozzle attachments, Ryobi offers a snap-on concentrator for its 40V blowers, and STIHL publishes fitment lists per model since its straight and curved nozzles are cut for specific blowers.

2Gutter cleaning kits
A gutter kit is a set of curved extension tubes that lets you blow debris out of your gutters while standing on the ground, no ladder. They come in OEM versions built for one blower family and universal versions that clamp onto most handheld blowers.
Universal kits like the Toro Universal Gutter Cleaning Kit attach to most battery, electric, and gas handheld blowers, and the WORX GUTTERPRO (WA4094) is built as a universal-fit accessory. OEM kits, like Husqvarna's set for the 125B and 125BVX, tend to seal better because they are cut for the exact nozzle.
Most consumer gutter kits are rated for single-story reach only, and they work best on dry debris, wet, packed muck often needs a vacuum or scoop instead. Also note: STIHL's gutter and vacuum attachments are compatible with its gas blowers only, not the battery line.

3Vacuum & mulch systems
Here is the distinction that trips people up: most "vacuum and mulch" products are not attachments at all, they are integrated 3-in-1 tools where the blower, vacuum, and mulcher are one unit. The WORX TRIVAC line is the obvious example.
The genuinely universal piece in this category is a collection system. The WORX LeafPro is a universal-fit accessory, an 8-to-16-foot hose with a mesh hood that seals over 32-to-96-gallon bins, so a blower/vac can suck leaves straight into a trash can instead of a small onboard bag.
Electric vacuum/mulchers like the TRIVAC are not built for wet leaves, damp material sticks and clogs the impeller. Save them for dry cleanup days.
4Air boosters
Air boosters are clamp-on tubes that slide over your nozzle and use the Venturi effect to pull in extra surrounding air, the pitch is more airflow without buying a stronger blower. The Cyclone2X is the best-known one: it fits most round nozzles between 2 and 4 inches, weighs under a pound, and claims to roughly double air volume.
This is the one category where we would slow you down. Real-world feedback on air boosters is genuinely mixed, plenty of owners report little or no improvement in how much debris actually moves, and the strap-on mounting can slip or fail on tapered nozzles. The physics is real; the practical payoff often is not. Treat claims of "double the power" with skepticism and check recent buyer reviews before spending.
5Inflator adapters
Some blowers double as inflators for air mattresses, pool floats, and inflatable furniture, using a small valve or nozzle adapter to channel the air. Milwaukee's M18 blower (0884-20), for instance, has an integrated inflation/deflation function with its own OEM valve kit.
You cannot turn a standard leaf blower into an inflator with an adapter. A normal blower draws air around the impeller, so it has no sealed inlet to reverse. Only blowers purpose-built with an inflation port, or a shop-vac with a blower outlet, will do this job. If your blower was not designed for it, no nozzle adapter will change that.
Will it fit my blower?
Before you buy anything universal, check three things:
- Nozzle diameter. Most clamp-on attachments and boosters are built for round tubes in the 2-to-4-inch range. Flat, oval, or square nozzles often will not seal.
- Power class. Gutter kits and boosters need real airflow behind them. A small cordless handheld may struggle to push debris through several feet of extension tube.
- OEM vs. universal. If your brand makes a first-party version, it will almost always fit and seal better. Reach for a universal kit when no OEM option exists, or when you want one accessory across several blowers.

Matching attachments to the job
The right attachment depends on what you are actually clearing. We have dedicated guides for the tricky debris types:
Frequently asked questions
What is the difference between a flat and round leaf blower nozzle?
A round nozzle moves a higher volume of air across a wider area, which suits loose, dry debris. A flat nozzle narrows the opening to raise air speed (MPH), which helps lift wet or stuck-on material. Many blowers come with both so you can switch based on the job.
Can I use any gutter cleaning kit with my leaf blower?
Universal kits fit most handheld blowers, but they seal and perform best when the nozzle diameter and airflow match. OEM kits built for your specific blower fit more reliably. Note that most consumer kits are rated for single-story reach and work best on dry debris, and STIHL's gutter attachments fit its gas blowers only.
Do leaf blower air boosters actually work?
The Venturi principle they use is real, but buyer feedback is mixed. Many owners report little change in how much debris actually moves, and the strap mounting can slip on tapered nozzles. Read recent reviews carefully before assuming a booster will meaningfully upgrade a blower you already own.
Can I turn my leaf blower into an inflator?
Only if the blower was designed for it. Models with a built-in inflation port (and shop-vacs with a blower outlet) can inflate mattresses and pool floats with a valve adapter. A standard leaf blower draws air around its impeller and cannot be converted with an aftermarket nozzle.
Are vacuum and mulch kits separate attachments?
Usually not. Most vacuum/mulch capability comes from integrated 3-in-1 tools like the WORX TRIVAC rather than a kit you bolt onto a blower. The one true universal accessory here is a collection system such as the WORX LeafPro, which routes mulched leaves into a large bin via a long hose.
