Rainbow, rainbow, rainbow... My sister first introduced me to the rainbow vacume cleaner. This vacume is soooo expensive. I guess my sister is more of a lover of the machine than I am. for some reason she just loves to see how dirty that water is. No matter how clean she feels her floor is. I guess this vacume does help keep the dust out of the air. I dont belive that the water that  needs to be emptied from the container would or ever actually  could be clean after a round of vacuming. With all these new types of vacumes coming out you know the kind that never looses suction? I do love to vacume...
