With the Nilfisk Combi Washer, you can suck up dirt and dust and mop the floor while you're at it. This electric mop has a powerful vacuum function that allows you to vacuum and mop in one go. The rotating microfiber roller removes stains from your hard flooring and also sucks up the water. The water that the mop sucks up, including any dust and dirt, ends up in another water tank, so you always mop with clean water. After cleaning, you put the electric mop in the stand. This way, it'll be ready for the next cleaning job.
