Possibly due to my white-painted desk being near the window, I notice dust accumulating every 1-2 days. In the past, I would tackle this issue by using wet wipes followed by drying with paper towels. However, over a year ago, I discovered a specialized device for desk cleaning - the Xiaomi Youpin (Nusign) mini desk vacuum priced at around $150 on Shopee.
The device boasts a simple design, compact size, and runs on 2 AA batteries. When I purchased it, it was only available in black, but now I see it comes in 4 colors.
Operation is incredibly simple. Alongside the device, there's a single toggle switch for powering the machine on/off, and right on the switch, there's a button to open the battery compartment lid - that's it:
Underneath, there are several rows of plastic bristles along with the dust suction hole. To empty the dust and clean the machine, simply twist the bottom part and remove the filter: 
I've added an extra piece of Velcro tape on the machine and another piece underneath the desk to store the machine after each use. When in use, just reach down to the desk to grab the machine - very convenient and frees up desk space.
CONCLUSION:
The device is incredibly convenient, with just enough suction power, reasonable price, and the battery lasts for several months before needing replacement. It's easy to clean. Anyone with a desk should definitely get one, and it can also be used occasionally to vacuum the bed.Drawback:Since it doesn't have a nozzle, it cannot vacuum small crevices.Product link on Shopee for your reference:bit.ly/XiaomiYoupinMini
