The RIDGID HD0919 is a 9-gallon, 18V cordless NXT wet/dry vac, one of RIGDIG’s latest offerings, lets you leave the cord behind. Or does it? We tested it against RIDGID’s 4 and 16 gallon corded vacs to see it really has what it takes for shop and job site work. Check it out!

Specs at a glance
- Model: HD0919 (tool only)
- Capacity: 9 gal wet/dry; liquid fill tops out just under 6 gal
- Power: RIDGID 18V — one or two packs (not 36V)
- Rated: 82 CFM / 116 air watts

- Included: 3 extension wands, utility / car / wet nozzles, white general-purpose filter
Power
This vac runs on one or two batteries. A second battery is not 36-volt power, but dry suction does get a clear boost with two packs in. This is unique as most dual battery tools need both batteries to run.
Rated at 82 CFM the 18V HD0919 sits well below a large corded 16 gallon stainless (~203 CFM). On fine sand with matching filters, the gap is barely noticable. On heavier debris like small rocks the corded 16-gal is 4-5 times as fast (see video).
Wet pickup is where the cordless holds up: through the included 1-7/8″ x 7 ft long hose, it emptied a 2-gal bucket as fast as the 4 and 16 gallon corded RIDGID vacs in testing.
The stock 1-7/8 in. hose is fine for dust, water, and fine debris, but for general jobsite cleanup it clogs too often. Fortunately you can swap to a 2-1/2 in. hose (no adapter needed) and the vac becomes useful for chips and rough debris.
Runtime
Expect about 12 minutes on two 4Ah batteries. Power fades slightly as the packs drain. Not as bad as a blower but you can see the difference in the video.
I was able to get through a day collecting saw dust for interior trim work on three 9Ah DeWalt batteries through an adapter, but only if I shut the vac off between cuts.
The big miss for me was I can’t use my momentary foot pedal to turn the vac on and off when cutting like I can with my corded vacs.
Fit: portable cleanup, wet spills, and intermittent dust collection with battery discipline. Miss: all-day continuous suction with zero pack management — keep corded for that role.
Who should buy
- Already on RIDGID 18V (or carrying an adapter)
- Shop or lightweight job site cleanup.
Skip it if you need a set-it-and-forget-it cut-station vac all day — stay corded or go with a cordless vac that has bluetooth or remote control.
Bottom line: The HD0919 is a real mid-size cordless shop vac with decent capacity and power to suck water and dust. The rock suction test in the video review proved to me that it does not have the power I want for job site cleanup. See ya!
