I purchased this in January 2025. Since I live alone and only use it about once a week, there are almost no scratches. I'm selling it at a lower price because I've lost the instruction manual. It's easy to use intuitively; there's nothing difficult. The mode change is on the switch on top. Eco Mode: Suction power approximately 12000Pa Strong Mode: Suction power approximately 15000Pa. The main body of the stick vacuum cleaner weighs only 0.7kg, a lightweight design that allows for easy one-handed operation. It can operate continuously for up to 40 minutes in Eco Mode and up to 20 minutes in Strong Mode. It's a 2-way design that can be used as both a vacuum cleaner and a handheld vacuum cleaner. The vacuum cleaner effectively removes 99.5% of dust and removes particles as small as 0.3 micrometers, allowing you to breathe fresher air. Also, the filter and head brush are washable, so you can keep the cordless cleaner clean.
