Research the cleanup job before the tank size.
Permitted debris, wet/dry use, included filters and attachment connections guide the shortlist.
Separate dry-only and wet/dry use
DCV501HB is a dry-only DEWALT example; DCV580H is a cordless wet/dry example. Shared battery context does not establish equivalent permitted cleanup. Read the exact manual for the material and operation.
Check included filters and accessories
GAS18V-3N includes a named washable HEPA filter and attachment set. PCL733B includes a cartridge filter and lists other filters separately. Keep included equipment distinct from compatible options; filter terminology alone is not a complete dust-control certification.
Plan the complete arrangement
Check the hose, nozzles, supported adapters and available power. Then verify the tank and pickup limits for the intended material. Catalog capacity labels and manufacturer references do not supply a tested suction or runtime ranking.
