The battery life is short. I really only need the vacuum for 10 minutes and therefore always have it in the charger to recharge. The suction power is very good, also the handiness - very small and light. What convinced me most was the low noise level compared to other devices. I am very satisfied and am happy to recommend the mini vacuum to others.
I can't judge the battery life because I rarely vacuum for more than 10 minutes. But the suction power is really good. Crumbs and hair are completely sucked up. That's exactly what I need it for, i.e. "on-the-fly" when I need it quickly for just that when I don't want to bring out the big wired main vacuum cleaner. I can really recommend it. I am very satisfied with it.
