Bobbles make a good jumper look tired long before its time. Run this shaver lightly over the fabric and the six-blade head lifts them off without pulling the knit; a three-height guard keeps delicate wool at a safe distance. The big 5 cm head makes quick work of sofa cushions, coats and blankets too. Fluff collects in a clear container you empty with a twist. It charges by USB-C and runs for about an hour on a full battery. A spare set of blades and a small cleaning brush come in the box.
