FLEX 24V Brushless Cordless 115 CFM 185 MPH Jobsite Blower Tool Only, Battery and Charger Not Included - FX5441-Z

A compact jobsite blower that favors precision over brute force

I’ve been using the Flex 24V jobsite blower for the past few weeks to keep benches, tools, and walkways tidy between tasks. It fills a very specific niche: quick, targeted cleanup in tight spaces where a full-size blower is awkward or excessive. If that’s your use case, this compact blower makes a strong case for itself.

Design and ergonomics

The first thing that stands out is the slim, linear profile. Unlike the stubby pistol-grip layout of many compact blowers, this shape lets me reach under miter saw stands, between racking, and along baseboards without contorting my wrist. It’s light enough for one-handed use, and the balance with a 4.0Ah–5.0Ah battery is neutral enough that my forearm didn’t fatigue during longer cleanup routines.

Build quality is what I expect from Flex: sturdy plastics, tight seams, and controls that don’t feel spongy. The nozzle is narrow, which matters for how this tool performs—it prioritizes air speed over volume. More on that below.

Controls that make sense on the job

Two controls matter most: a variable speed dial and a turbo button. The dial lets me preset airflow and then feather with the trigger for finesse—ideal for blasting dust off a table saw without sending small parts flying. Turbo is a momentary bump that brings maximum output on demand. I tend to run at a mid setting for general cleanup and use turbo in short bursts to move stubborn debris or reach further down a driveway.

I appreciated that the dial holds its setting, so I can set-and-forget for repetitive tasks. The turbo button is well placed for a quick thumb press without shifting grip.

Performance in the real world

Flex quotes up to 115 CFM and 185 MPH. In practice, the blower behaves like a precision air knife rather than a leaf mover. The narrow nozzle focuses the air stream, so it excels at:

• Clearing sawdust and drywall dust from tools and work surfaces
• Blowing debris out of tracks, corners, and between shelving
• Cleaning out truck beds and floor mats
• Sweeping a garage or porch where you want control, not chaos

Where it’s less effective is moving piles of leaves, wet clumps, or heavier chips over distance. That’s a basic tradeoff of airspeed versus volume. With 115 CFM, you won’t get the “push” that larger yard blowers provide. If you’re expecting to clean an entire yard or move damp mounds of debris, this isn’t the tool for it. But for controlled, close-range cleanup—especially in and around a jobsite—it’s squarely in its element.

I also found it handy for delicate tasks. On its lowest settings, it’s gentle enough to clear dust without disturbing layout marks or lightweight offcuts, and the ability to quickly ramp via turbo means you’re not constantly fiddling with the dial.

Runtime and batteries

This is a tool-only purchase, so your experience will lean heavily on the battery you pair with it. Using a 5.0Ah Flex 24V pack, I averaged roughly 15–20 minutes of mixed use with frequent turbo bursts. Continuous turbo cuts that significantly; it’s a drain-by-design feature for short, high-output bursts.

On lower speeds, runtime stretches out meaningfully and is better suited to longer sweeping tasks, but if your workflow leans on turbo to move more stubborn debris, plan for short stints or carry a spare pack. The Flex platform’s THERMA-TECH heat management and the higher-output chargers do their part to get you back to work quickly, but the reality is that compact blowers like this trade runtime for portability and precision.

If you already own Flex 24V batteries and a fast charger, the runtime is manageable with a battery rotation. If you’re new to the platform, factor in the cost of at least one mid-to-high-capacity pack.

Noise

The pitch is a touch higher than some compact blowers I’ve used. It’s not painfully loud, but it has a noticeable whine, especially in turbo. Ear protection is still a good idea, and the sound profile is what I’d expect from a small, high-velocity nozzle.

Durability and day-to-day use

I’ve knocked it off a workbench, tossed it into the truck, and dragged it across concrete. No creaks, no loose parts, and the trigger and dial still feel crisp. The compact form factor is great in crowded spaces and for quick grabs—this is the blower I actually carry from task to task because it doesn’t get in the way.

Dust control has been solid; I haven’t noticed clogging or performance tapering after fine dust sessions, though I try not to run it nose-down into powder for long stretches. As with any blower, a quick pass with compressed air or a brush keeps it happy.

Platform advantages

If you’re already invested in Flex 24V, the cross-compatibility is the major draw. It drops right into a kit bag alongside drills, saws, and lights, and shares the same packs and chargers. Flex’s limited lifetime warranty (with timely registration) is another confidence booster, especially for a tool you’ll toss around the site.

Because it’s sold without a battery and charger, newcomers to the platform should price out a kit. A 5.0Ah pack pairs well with this blower; a 2.5Ah will work but shortens runtime enough that you’ll want a spare.

What it is—and what it isn’t

• It is a compact, high-speed, low-volume blower that’s excellent for precision cleanup and tight spaces.
• It isn’t a yard or acreage solution, and it won’t replace a backpack or high-CFM blower for moving heavy or wet debris.

As long as you keep that framing in mind, the performance lines up with expectations.

Pros

• Slim, linear body reaches places bulky blowers can’t
• Variable speed dial plus turbo gives precise control
• Strong, focused airflow for dust, chips, and site cleanup
• Light and easy to handle one-handed
• Plays nicely within the Flex 24V ecosystem
• Solid build quality and reassuring warranty support

Cons

• Lower CFM limits performance on leaves and heavier debris
• Turbo drains batteries quickly; expect short stints at max power
• Higher-pitched whine compared to some competitors
• Tool-only purchase means added cost if you’re not already on Flex 24V

Who should buy this

• Tradespeople and DIYers who want a dedicated jobsite/garage blower for benches, tools, vehicles, and tight spaces
• Existing Flex 24V users who can leverage their current batteries and chargers
• Anyone valuing control and compactness over raw yard-clearing power

Recommendation

I recommend the Flex 24V jobsite blower for users who understand and need its specific strengths: precise, high-velocity airflow in a compact, easy-to-carry package. It’s excellent for cleaning tools, workstations, and confined areas, and it integrates well if you’re already on the Flex 24V platform. I wouldn’t choose it as a primary yard blower or for moving heavy, wet debris—its lower CFM and turbo-dependent performance aren’t built for that. If you’re after a portable, well-made site cleanup tool and you’re comfortable managing battery runtime, this blower is a smart, practical addition.
