The stylish Wahl 9639-017 Clip N Rinse is ideal for home hairdressing. This mains-rechargeable clipper offers freedom of movement as it can be used with or without the cord, while the Rinseable blade makes keeping this clipper hygienic simple. The Wahl 9639-017 has up to 45 minutes cordless runtime, allowing you enough time to perform multiple full-head haircuts in-between charges. This makes it a perfect family clipper as you can use it for the whole family, rinsing the blades in between cuts. The detachable, snap on/off blades of this Wahl 9639-017 clipper are made from high-carbon steel, giving them strong teeth to feed the hairs through & allowing you to get an accurate & definitive cut. Being able to remove the blades means that you can rinse them separately from the unit. This ensures a thorough clean, to remove all those unwanted hairs that start to clog up behind the blades & in the mechanism, which can slow the motor & hinder performance of the 9639-017 clipper.
