How to confirm it's your model
Find the vacuum's rating plate: it's usually on the bottom or under the bag compartment lid. It shows the exact model. If it matches the Kärcher WD2 or one of its variants (WD 2, WD2.200, WD 2.200, WD 2.210, WD 2.240, WD 2.250), these bags will fit.
Tip: if you still have a used bag, check the cardboard collar. If it says 6.904-322.0, you're on the right track.
How to change the bag on the Kärcher WD2
- Unplug the vac and release the latches to lift off the motor head.
- Remove the used bag by pulling its collar off the inner intake port and throw it away sealed.
- Push the new bag's collar onto the tank's intake port until it's secure.
- Spread the bag across the bottom of the tank and reattach the motor head.
- For picking up liquids, always remove the bag (and on many models the paper filter too).
How often should you change the bag?
It depends on what you pick up. Fine construction dust (drywall, cement, sanding) clogs it in one or two sessions; cleaning out the garage or car it can last months. The clear sign is a loss of suction.
Equivalent part numbers

Frequently asked questions
What bag does the Kärcher WD2 take?
The Kärcher WD2 uses Kärcher KFI 222 (WD 2 / MV 2) bags. The genuine part number is 6.904-322.0 (also listed as KFI 222). Compatible bags that list that part number or the model in the title also fit.
Do compatible bags work in the Kärcher WD2?
Yes. Good-quality compatible bags have the same cardboard collar and are usually multi-layer microfiber, which filters as well as or better than the original paper. Pick packs with lots of reviews that list part number 6.904-322.0.

Can I use the Kärcher WD2 without a bag?
Yes, and you must remove it to pick up liquids. For dust and dry debris, always use a bag: it protects the filter, maintains suction, and keeps fine dust from blowing out the exhaust.
