Ridgid 12 Gallon NXT Wet/Dry Vac vs Ridgid 9 Gallon 18V Cordless NXT Wet/Dry Vac
Quick take: The Ridgid 9 Gallon 18V Cordless NXT Wet/Dry Vac costs $10 less.
Which one to buy
Batteries are the hidden line item. The Ridgid 9 Gallon 18V Cordless NXT Wet/Dry Vac is listed at $99 as a bare tool, with no battery or charger in the box, so it only undercuts the corded Ridgid 12 Gallon NXT Wet/Dry Vac at $109 if you already own Ridgid 18V packs. Owners say one 9.0Ah Octane pack gives about 34.5 minutes, and filling both battery ports gets you to about 69 minutes.
If you're starting from scratch, the corded 12-gallon is the stronger and cheaper machine. It moves 144 CFM against the cordless model's 82, holds three more gallons, and has a drain spigot the cordless one lacks, which owners say makes emptying wet jobs far less messy. Testers rank its large-debris pickup best in class, clearing sawdust and wood chips faster than rivals, and owners praise the locking hose that doesn't pop loose. The trade-offs owners mention are a 15-foot cord that means extension-cord shuffling, water lift that trails the best in the class, no automatic filter cleaning, and 88 dBA under load, loud enough for hearing protection.
The cordless 9-gallon earns its keep where cords are a nuisance: vehicles, job sites without power, or the far end of a yard. Owners and testers say it picked up 3-inch nails and screws and cleared 5 gallons of water in about 9 seconds, which is corded-class wet pickup. Its weaknesses are a brushed motor, airflow closer to a small corded vac, and real heft at 16.28 lbs before batteries. Both carry Ridgid's lifetime warranty on registration.
Buy the 12-gallon unless you already own Ridgid 18V batteries and hate dragging a cord. If you do have the packs, the cordless one is a capable bucket vac for $10 less.
Ridgid 12 Gallon NXT Wet/Dry Vac
Go this way if you don't own Ridgid 18V batteries, want more airflow and capacity, and value the drain spigot and locking hose.
Ridgid 9 Gallon 18V Cordless NXT Wet/Dry Vac
Choose it if you already have Ridgid 18V packs and need to clean where there's no handy outlet, like cars or job sites.

Ridgid 12 Gallon NXT Wet/Dry Vac vs Ridgid 9 Gallon 18V Cordless NXT Wet/Dry Vac: common questions
Is the cordless 9-gallon really cheaper than the 12-gallon?▾
Only if you already own Ridgid 18V batteries. The $99 price is for the bare tool. Owners say serious jobs need two 9.0Ah packs for about 69 minutes of runtime, and those add real cost if you're new to the platform.
Which is better for a flooded basement?▾
For long jobs, the corded 12-gallon. It runs as long as you have power, holds more and has a drain spigot. Testers say the cordless model clears standing water quickly, but runtime is capped by your batteries and there's no spigot for emptying.
Do I need to register either one for the lifetime warranty?▾
Yes. Owners of both note Ridgid's Full Lifetime Warranty activates only after registration. On the cordless model, batteries and charger fall under a separate service agreement that needs its own registration.
