Compact, simple-style vac available in white, blue, orange, green, yellow, or black. Small enough to tuck in a drawer and grab for quick cleanups
1400mAh lithium battery with USB direct charging. 1 hour charge gives you about 90 minutes of runtime at 0-200W, which is plenty for desk and keyboard debris

Lightweight and cordless, so you can hit tight spots around monitors, cable organizers, and under your mousepad without moving everything

It’s the fast cleanup tool that keeps your setup from getting grimy between deep cleans. Good match if you want to keep the desk looking clean without dragging out a full-size vacuum.
