Hitachi Stick Vacuum Cleaner Rotating Head Body for Karu Stick Part Model: D-DP32 Part Number: PV-BL1J-003 This item was used in a typical household for exactly one year. I have discarded the vacuum cleaner body and the instruction manual, so I don't know the model of the main unit. In preparation for listing, I cleaned it as thoroughly as possible, but there are areas where dust and cotton fluff cannot be completely removed due to the looped brush design. Please check the photos and consider this point, as well as the fact that it is a used item, before purchasing. Thank you.
