The little things — bags, cuffs, wands, literature — are easy to substitute and easy to get wrong. A cheaper bag that tears earlier, a wand that's slightly off dimensions, a manual that's for a different machine model. Small mismatches, but they add up.
This is the genuine Nilfisk Advance OEM PAPER BAG 10PK MB53CV, part number VA61309EU, brand new in the box. Fits right, works right, holds up to real use.
