This item has been confirmed to be in working order. The reason it's listed as junk is that while the attachments in the photos can be installed, items with electrodes, such as the stick, do not attach securely and wobble. Therefore, it can only be used as a handheld vacuum cleaner. Would it be suitable for use in a car, for example? Also, the trigger part was previously broken, and the broken part has been replaced with a third-party part. A third-party additional filter is also included.
