How long does it run on a single battery charge?

With a 9.0Ah Octane battery, testers got about 34.5 minutes of runtime. Using both battery ports with two 9.0Ah packs extends that to roughly 69 minutes of continuous operation.

Can it actually handle standing water like a corded shop vac?

Yes - in testing it cleared 5 gallons of water in under 10 seconds, performance that's genuinely comparable to a full-size corded 9-gallon unit, which is unusual for a cordless vacuum.

What batteries does it use, and are they included?

It runs on any Ridgid 18V battery, including the higher-capacity Octane line. Batteries are typically sold separately from the bare tool, so factor in the cost of one or two 9.0Ah packs if you're not already on the Ridgid 18V platform.

Is the motor brushless like premium cordless tools?

No - it uses a brushed motor, which is the one notable spec compromise reviewers flagged. It doesn't significantly hurt real-world performance in testing, but it's worth knowing if brushless motor longevity matters to you.

How does the suction compare to a corded shop vac of similar size?

At 82 CFM, it's roughly comparable to a 6-gallon corded Ryobi rather than a top-tier corded vacuum, but reviewers still rated it a no-compromise replacement for a corded 9-gallon unit given its combination of capacity, water pickup, and cordless convenience.

Ridgid 9 Gallon 18V Cordless NXT Wet/Dry Vac

Name: Ridgid 9 Gallon 18V Cordless NXT Wet/Dry Vac
Brand: Ridgid
Price: 99 USD
Availability: InStock

This is Ridgid's flagship cordless shop vac — a real 9-gallon bucket, not a handheld, that runs on Ridgid's 18V Octane battery platform instead of a proprietary battery. That's a big deal if you already own Ridgid power tools: no new charger or battery ecosystem to buy into. It has two battery ports, so you can run two packs at once for extended runtime instead of stopping to hot-swap mid-job — testing on the predecessor model measured 69 minutes on dual 9.0Ah batteries. This is sold as a bare tool with no battery or charger included, so budget for that separately; a kit with a charger and two Octane batteries has run around $239 versus roughly $99 for the tool alone. It still has swivel casters and a blower port like the corded models, though it skips the built-in drain spigot. A professional reviewer of the predecessor model found no significant drawbacks, noting it cleared 3-inch nails and screws without clogging and pulled 5 gallons of water in under 10 seconds. Two warranty notes worth knowing: the vac body carries Ridgid's Full Lifetime Warranty, but the battery and charger are covered separately under Ridgid's Lifetime Service Agreement, which requires its own registration. Ridgid doesn't publish a noise rating for this model.

Highlights

Runs on Ridgid's 18V Octane platformDual battery ports for extended runtime9-gallon tank, no cord

Pros

✓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

Cons

✗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

Owner Insights(26 discussions)

Ridgid built this 9-gallon cordless NXT to answer a specific complaint from jobsite owners: cordless shop vacs are usually small and underpowered, forcing anyone doing real cleanup to run a corded unit off an extension cord anyway. Testing backs up the pitch - reviewers called it "a no-compromise battery-powered replacement for a corded 9-gallon vac" and rated it 9.0 out of 10, with the review explicitly stating there were no significant drawbacks beyond the choice of a brushed motor over brushless.

In practice, the standout feature is genuinely large-vacuum performance without a cord: it picked up 3-inch nails and screws in testing and cleared 5 gallons of water in under 10 seconds, matching what you'd expect from a full-size corded shop vac. The dual battery ports are the other key piece - running two packs simultaneously stretches usable runtime past an hour, which matters because a single 9.0Ah battery only lasts about 34.5 minutes on its own. Airflow at 82 CFM is solid but not class-leading, roughly matching a 6-gallon corded Ryobi rather than beating dedicated high-CFM corded models.

Buy it if you're already invested in Ridgid's 18V Octane battery platform and want to eliminate extension cords from your cleanup routine without sacrificing real capacity - the 9-gallon tank and dual-battery runtime make it genuinely usable for full jobs, not just quick touch-ups. If you're starting from zero on batteries, a corded Ridgid NXT in the same capacity range costs less upfront and doesn't require buying two 9.0Ah packs to get comparable runtime.

Pros

+Runs on any Ridgid 18V battery, including Octane packs, so owners already invested in Ridgid's cordless tool platform don't need a dedicated vacuum-only battery
+Genuinely powerful for a cordless vacuum - testers picked up 3-inch nails and screws with it and cleared 5 gallons of standing water in about 9 seconds
+Dual battery ports let you run over an hour continuously by swapping in a second pack without stopping to recharge, which owners specifically value for longer jobs
+9-gallon capacity is unusually large for a cordless shop vac - most cordless competitors top out smaller, and this one rivals corded units in size
+Tool-free setup with no assembly required out of the box, so it's ready to use immediately
+Ridgid's Full Lifetime Warranty applies on registration, matching the coverage on the brand's corded NXT lineup

Cons

−Uses a brushed motor rather than brushless, which typically means somewhat shorter motor lifespan and slightly less efficiency than the brushless motors now common in premium cordless tools
−Airflow at 82 CFM is comparable to a 6-gallon corded Ryobi, meaning you're paying for cordless convenience and capacity rather than class-leading suction power
−Runtime is battery-dependent - a single 9.0Ah Octane pack only gets about 34.5 minutes, so serious jobs really need the second battery port populated to avoid mid-job recharging
−At 16.28 pounds bare (before batteries), it's noticeably heavier to carry than Ridgid's smaller corded portable models
−Two 9.0Ah batteries represent a real cost on top of the vacuum itself if you're not already in the Ridgid 18V ecosystem
−Dual battery ports add real bulk and weight to the housing compared with a single-port cordless vac, a direct tradeoff for the extended runtime they enable
