DeWalt DCV585B: the best HEPA-rated cordless construction vacuum
The DeWalt DCV585B is the only HEPA-certified cordless construction vacuum in our test group, which makes it the correct choice for any work involving silica dust from concrete or masonry. The FLEXVOLT battery sustained full suction through our 20-minute connected tool test without the performance degradation we noted in models running on lower-voltage batteries. The tool-connect port activated and deactivated correctly in every test with both the angle grinder and orbital sander.

DeWalt DCV585B: the best HEPA-rated cordless construction vacuum
The DeWalt DCV585B is the only HEPA-certified cordless construction vacuum in our test group, which makes it the correct choice for any work involving silica dust from concrete or masonry. The FLEXVOLT battery sustained full suction through our 20-minute connected tool test without the performance degradation we noted in models running on lower-voltage batteries. The tool-connect port activated and deactivated correctly in every test with both the angle grinder and orbital sander.
Milwaukee 0882-20: the M18 alternative for Milwaukee platform users
The Milwaukee M18 cordless vacuum lacks HEPA certification but provides strong suction and wet/dry capability at a lower price. It is the natural choice for Milwaukee platform users and handles typical construction cleanup including sawdust, concrete dust, and debris effectively. For work not involving silica dust exposure, the Milwaukee's non-HEPA filter is adequate for most regulatory purposes.
Buying considerations
HEPA filtration
If your work involves concrete cutting, masonry drilling, or any silica-producing activity, HEPA-certified filtration is required by OSHA standards. Non-HEPA filters do not adequately capture silica dust particles.
Wet/dry capability
A wet/dry model handles both dry debris and liquid spills, which are common on construction sites. Verify the model includes instructions for switching between wet and dry modes.
Tool connect port
Automatic tool-connect turns the vacuum on when your tool runs and off when it stops. This provides hands-free integrated dust extraction that significantly improves air quality at the cutting source.
Capacity
A 2-gallon capacity is a practical minimum for construction use. Larger capacities (3 to 5 gallons) reduce emptying interruptions during heavy debris sessions.
Battery compatibility
Choose a model compatible with your highest-capacity battery platform. Construction vacuums draw significant power; high-capacity batteries provide better runtime under sustained dust extraction load.
Questions answered
For concrete cutting, drywall sanding, or any silica dust exposure work, OSHA recommends engineering controls including HEPA-rated dust extraction. For general sawdust cleanup, standard filtration is adequate.
Yes, but drywall dust clogs filters very quickly. Use a pre-filter bag for drywall dust work and check filter condition frequently during a drywall phase.
Tool-connect ports turn the vacuum on automatically when a connected power tool starts and turn off when the tool stops. This provides hands-free dust extraction integrated with your cutting or grinding work.
Wet/dry models like the DeWalt DCV585B handle water, coolant, and construction liquids. Remove the HEPA filter before wet use and reinstall it for dry operation.
