This is a HITACHI stick vacuum cleaner, model PV-BFH500, featuring strong, weak, and automatic modes, powered by a 21.6V battery. Thank you for viewing. It stopped working in late 2024, shutting off after a few minutes of use. I sent it to Hitachi for repair, and it worked for a few days, but now when I turn it on, it makes a "kyu-in" sound, as if the motor isn't running, and it doesn't move. I don't know what the cause is, so I'm selling it as junk. Would anyone interested in using it for parts like this? The battery is also depleted, so please assume it doesn't work. I will wrap it in bubble wrap for shipping. I look forward to your purchase if you understand.
