Field Verdict: Tier S / Essential Grab-and-Go Shop Cleaner. Tested rigorously on hardwood joinery, framing, or homestead pasture maintenance.
What We Like
- Dual-power design runs on 20V MAX battery or standard 120V extension cord
- Washable HEPA gore filter traps fine drywall and sawdust down to 0.3 microns
- All hose and nozzle attachments clip securely onto the chassis without rattling loose
Flaws But Not Dealbreakers
- 2-gallon tank fills up fast when connected to a thickness planer, keep it for hand tools and cleanup
- Hose is relatively stiff in freezing weather until it warms up
The Straight-Shooter Take
Pulling out a 14-gallon drum vacuum to clean up five minutes of drill press shavings or vacuum out the truck cab is a hassle. This 2-gallon DeWalt box vac is what actually gets grabbed every single day.
The corded/cordless dual power is brilliant: snap on a 5.0Ah 20V battery to clean up sawdust in the truck bed or out at the tractor shed, or plug it into the wall for continuous benchtop miter saw extraction.
Where It Earns Its Keep
- HEPA Filtration: The pleated filter rinses clean with water in 30 seconds and keeps fine hardwood dust from blowing back into the shop air.
- Compact Form Factor: Rectangular toolbox shape stacks neatly in truck storage or under the bench.
- Quick-Connect Blower: Flip the hose from suction to exhaust port to blow sawdust out of intricate machinery gears.
