3 IN 1 VACUUM CLEANER GZ000011 No Brand Item Portable Multi-functional High Suction Power Wireless Home/Car Dual-Use Mini Small Handheld Powerful Bed Vacuum Cleaner * Never used after purchase. * Charging and operation are completely problem-free. * The inside of the dust container was deformed from the beginning. → The vacuum cleaner function seems to be fine. ☆ I bought it because it can also be used as an air pump, but I can't attach the adapter no matter what. There seems to be a misalignment in the adjuster part. I thought about modifying it myself, but I'll leave it to someone who is good with their hands.
