WORKSHOP Wet/Dry Vacs Shop Vacuum Accessories WS25001A Dusting Brush Attachment for Wet Dry Vacuum Cleaners, Fits 2-1/2-inch Extension Wands and Hoses

Why I reach for this brush

Of all the nozzles in my shop-vac drawer, a dusting brush is the one I use most. The WORKSHOP dusting brush (model WS25001A) snaps onto a 2-1/2-inch hose and turns a blunt shop vac into a far more precise cleaning tool. If you’re constantly chasing fine dust around the shop, touching up baseboards after a sanding session, or de-fuzzing vents and blinds, this attachment earns its keep quickly.

Setup and fit

This is a friction-fit accessory sized for the common 2-1/2-inch shop-vac category. On my main 2-1/2-inch hose, it seats with a reassuring push—snug enough to lift the wand by the brush without worry, yet easy to twist off. On another hose (a different brand), the connection was a touch looser. An inexpensive adapter solved it, but it’s a reminder that “2-1/2-inch” in shop-vac land can mean slightly different inner/outer diameters depending on the manufacturer.

A quick tip before you buy: measure the outside diameter of your wand or the inside diameter of your hose cuff. This brush is a standard male friction fitting designed to insert into a matching female cuff or wand. If your hose uses a proprietary bayonet or a different size family (1-7/8 or 1-1/4 inches), you’ll need an adapter.

Build and design

The brush head is compact and round, with a ring of moderately stiff synthetic bristles set into a molded plastic body. There’s no swivel or articulation—the neck is fixed—so angles are dictated by how you hold the wand. The simplicity works in its favor: there are no hinges to crack, and the bore through the center maintains a wide, straight path for airflow.

Two details stand out in use:
- The bristle ring is dense enough to corral fine dust but spaced so air can keep moving. You don’t get that choked-off feeling some overly soft, packed bristles cause.
- The opening is full 2-1/2-inch class, so the vacuum isn’t forced to a narrow chokepoint. That translates to better pickup of larger chips and shavings compared to smaller dusting brushes.

The plastic shell isn’t flashy, but it’s thick enough not to flex under pressure. I’ve knocked it off a bench and used it to muscle into rough edges; it shows scuffs, not cracks.

Performance on real tasks

A dusting brush is about control—lifting grime off a surface and directing it into the airstream without smearing or scratching. Here’s how the WS25001A handled my regular list:

• Shop machines and benchtops: On my miter saw and drill press, the bristles reached into T-tracks, ribbing, and around fasteners where a straight crevice tool can’t. Fine sawdust vanished on the first pass; larger chips followed without clogging. Airflow felt strong throughout.
• Baseboards, window sills, and door trim: The bristle stiffness is a net positive here. It scrubs the tiny profile details where dust clings, and the wide opening avoids snowplowing debris ahead of the nozzle.
• Car mats and cargo areas: It’s excellent for dislodging grit from rubber mats and textured plastics. I wouldn’t use it on glossy trim—more on that below—but for rugged surfaces it’s quick.
• Vents, blinds, and light fixtures: The bristles get into louvers and seams, and the open design keeps suction consistent even when pressed against flat slats. On overhead jobs, a couple of extension wands plus this brush beat balancing on a ladder with a hand vac.
• Drywall and remodeling dust: This is where the 2-1/2-inch size matters. The brush keeps up with a lot of fines without choking, and the larger throat doesn’t load the filter as quickly as smaller accessories.

On delicate finishes (piano gloss, soft plastics, or sensitive instrument panels), the bristles can be a bit firm. I had no issues on painted trim, unfinished wood, and powder-coated metal, but I switched to a softer detailing brush for high-gloss surfaces just to be safe.

Where it shines

• Airflow and debris handling: The 2-1/2-inch path keeps the vacuum breathing freely. It pulls both light dust and surprising amounts of crumbly debris without drama.
• Control in crevices: The bristle length and density strike a good balance—stiff enough to agitate, long enough to conform.
• General-purpose reach: It’s compact, so it sneaks between clamps, into drawer corners, and around bolt heads.

Where it struggles

• Tight clearances: The 2-1/2-inch head is bulkier than 1-7/8-inch counterparts. In cramped cabinets and tight car interiors, that extra girth can be limiting.
• Delicate finishes: The bristles are not “detail brush” soft. If you’re dusting polished piano black or fragile screens, opt for a softer, smaller brush.
• Fitting across brands: Most 2-1/2-inch systems play nicely, but tolerances vary. If your hose cuff is just a hair off, expect to use an adapter for a rock-solid connection.

Durability and care

Out of the box, I check any brush by tugging a few bristles and tapping it over a bin. On my unit, a couple of stray fibers shed early and then it settled in. After weeks of use—including pressing hard into rough plywood edges and concrete block—only a few bristles loosened. That’s normal wear for a dusting brush that gets used aggressively.

Maintenance is simple:
- Knock out packed dust by tapping the side of the head against your palm or the shop trash can.
- For sticky debris, a quick rinse in warm, soapy water and thorough drying keeps the bristles springy.
- Avoid prolonged heat or chemical exposure; it can deform the bristle set.

Alternatives and pairing

If your workflow is mostly floors, a floor brush or squeegee/bare-floor head will be faster. I pair this dusting brush with a wide floor tool for large areas and a narrow crevice tool for deep channels. If you regularly work in tight interiors or around electronics, a smaller, softer brush (often in the 1-7/8-inch family) is a better match, using an adapter if needed.

Value

There’s not much to a dusting brush, which is exactly why the small design choices matter. Here, the value comes from:
- A full-bore 2-1/2-inch passage that preserves suction.
- Bristles that actually do the scrubbing, not just glide.
- A body that stands up to shop abuse.

Could it be cheaper? Sure. But the cost makes sense for an accessory that effectively upgrades how your vac handles fine dust. If you use your vacuum for more than just big pickups, this earns its space.

Tips for best results

• Use an extension wand overhead; the fixed neck keeps the angle consistent and prevents wrist strain.
• Don’t mash the bristles flat. Let them do the work with light pressure so air can flow through.
• Keep a softer brush on hand for sensitive finishes, and swap quickly rather than compromising on pressure.
• If the fit is loose, a proper adapter beats tape. You’ll get a better seal and a safer connection.

The bottom line

The WS25001A is a straightforward, well-executed dusting brush for 2-1/2-inch shop vacs. It prioritizes airflow and effective agitation, which is exactly what I want from a brush in this size class. It isn’t the gentlest option for delicate surfaces and it won’t solve every fit quirk across brands without an adapter, but as a day-in, day-out shop companion, it performs reliably.

Recommendation: I recommend this tool for anyone running a 2-1/2-inch shop vacuum who needs to clean fine dust from trim, machines, vents, and general surfaces without sacrificing airflow. If your work centers on delicate finishes or very tight spaces, pair it with a smaller, softer brush. Otherwise, this becomes the attachment you’ll reach for more than you expect—because it simply gets the job done.
