Kärcher NT 40/1 Tact Vacuum Bags: Part 2.889-155.0 & In-Stock Packs

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 NT 40/1 Tact or one of its variants (NT 40/1 Tact Te L, NT 40/1 Tact Te M, NT 50/1 Tact Te L, NT 50/1 Tact Te M, NT40/1), these bags will fit.

Tip: if you still have a used bag, check the cardboard collar. If it says 2.889-155.0, you're on the right track.
