This is the dust case for a Hitachi stick vacuum cleaner. I have cleaned it, but there is some remaining dirt that I couldn't remove, so please check the images. This is a used item, so please refrain from purchasing if you are looking for a product in new condition. Applicable models: PV-B550E8 PV-BH500A1 PV-BH500H PV-BH900H *The filter shape is slightly different for the following models, but it can still be installed and used: PV-BH900J PV-BH900K etc. *I am also listing this on other sites, so it may be removed at any time. Thank you for your understanding.
