The Koblenz WD-12K is a 12 gallon, 5.5 peak HP wet/dry vacuum for the jobs that ruin a regular vacuum: water pickup after a strip job or a small flood, drywall and sawdust in a shop, glass and gravel in a garage, leaves and cargo debris out of a truck bed. Twelve gallons is the practical sweet spot for one person, big enough that you are not dumping the tank every ten minutes, small enough that you can still move it when it is half full of water.
Built for
- Water recovery. Pulling up rinse water after floor stripping, overflowed sinks, water heater leaks and wet basements.
- Shop and jobsite cleanup. Sawdust, drywall dust, screws, offcuts and sweepings.
- Garages and vehicles. Gravel, salt, road grit, pet hair and cargo area debris.
- Blowing instead of vacuuming. It converts to an air blower for clearing driveways, decks, gutters and workbenches.
- Facility maintenance carts. Reinforced wheels and rugged casters let it be pushed around a building instead of carried.
The 5.5 peak HP motor and 12 gallon high-impact tank do the heavy lifting, and the on-board accessory kit means the tools are with the machine instead of lost in a shop drawer: telescopic wands, hose, a floor brush with squeegee for water pickup, a crevice nozzle and a pick-up tool. A 15 foot cord covers a two-car garage or a good stretch of corridor without moving outlets. The air exhaust system converts the machine to a blower, which is the feature owners tend to use far more than they expected.
One practical note that applies to every wet/dry vac: change the filter setup when you switch modes. Running a dry cartridge filter during water pickup is the single most common way people damage a shop vacuum. Pull the dry filter for wet work, and let the tank dry before going back to dust.

Frequently asked questions
Can the WD-12K pick up water?
Yes. It is a true wet/dry vacuum with a 12 gallon tank and a floor brush with squeegee for water pickup. Remove the dry filter before vacuuming liquids.
Does it work as a blower?
Yes. The air exhaust system converts it to a handy air blower for clearing driveways, decks, shop floors and workbenches.
How long is the cord?
Fifteen feet, which covers most garages and shop bays without changing outlets. Use a heavy gauge extension cord if you need more reach.
What accessories are included?
Telescopic wands, the hose, a floor brush with squeegee, a crevice nozzle and a pick-up tool, all stored on board the machine.
Is 12 gallons enough for a flooded room?
For a small spill or a strip-job rinse, yes. For a large standing-water loss you want a dedicated extractor or a submersible pump; the WD-12K is best for cleanup and detail recovery after the bulk water is gone.
