Pros & cons

Ridgid 3 Gallon NXT Portable Wet/Dry Vac

  • RIDGID Sweep built-in dustpan is a genuinely useful, unique feature
  • Lightweight and stackable for easy storage
  • High CFM (100) for its compact size
  • Corded, so no battery runtime ceiling to manage
  • Full lifetime warranty on the vac body
  • 3-gallon tank empties fast on anything beyond a small job
  • No wheels — this is a carry unit, not a roll-around one
  • Tethered by a 15-foot cord
  • No published noise rating
  • Ridgid also sells a larger, non-NXT 4-gallon portable (WD4070) that's easy to confuse this with

Ridgid 9 Gallon 18V Cordless NXT Wet/Dry Vac

  • Compatible with Ridgid's existing 18V Octane battery lineup — no separate battery ecosystem to buy into
  • Dual battery ports extend runtime without hot-swapping mid-job
  • A real 9-gallon tank, not a scaled-down handheld
  • Professional reviewer of the predecessor model found no significant drawbacks and praised its wet pickup speed
  • Casters and blower port carried over from the corded NXT lineup
  • Sold as a bare tool — battery and charger add significant cost on top of the tool price
  • No built-in drain spigot, unlike the corded 12/14/16-gallon models
  • No published noise rating
  • Runtime depends heavily on how many batteries you run at once
  • The battery/charger warranty is separate from the vac's warranty and requires its own registration
