Have been looking around for a lightweight and wireless portable vacuum cleaner and I saw this one from the YouPin Store. What I can say is that the suction is pretty strong and whats best is that I can use this freely to clean the wall with the roller at the bottom, it will definitely brush off the dirts on the wall high above. It can even help you clean the ceiling, I know those pesky spider webs are the first to go.
My comment is that its light, since its made out of aluminum materials, it doesnt feel that heavy at all. Whats best is that it has dual mode, low and high suction mode, which you can freely switch. There is a battery indicator to let you know how much battery you still have before charging it up again.
