Electric ice scraper from Kärcher, a compact handheld device with a rotating disk. Battery operated, so no wires. The disk is 11 cm in diameter with six plastic blades, and it spins at 500 rpm. The battery here is powerful - 2500 mAh, with one charge you can clean the car several times. Using the squeegee is easy: you turn it on, apply it to the glass with a little pressure, and drive it on the surface. It's lightweight, comfortable in your hand, and much more comfortable than a regular squeegee.
