The Rainbow has been designed not only to give constant cleaning efficiency but also to deliver fresh clean air into the home while it is cleaning. How? Water is the answer! Water is the filter: all the dirt and dust is trapped in the water and the home is filled with fresh clean air. Add our deodoriser or fragrance, or use the mentholaire vapouriser fluid and replace a vapouriser. With the Rainbow, you can clean everything in your home. All soft furnishings, dusting and sweeping, wash and dry hard floors, defrost the fridge and freezer; cleans pillows and mattress and if you do have rugs or carpet it will deep clean and shampoo those as well.
