Simply rinse the blades under running water for quick cleaning. CERAMIC TITANIUM BLADE: This professional self-sharpening blade stays shaper longer, and cuts all hair types. It is detachable for thorough cleaning.
The good thing about this trimmer is that it comes with plenty of guards and it has a nice led to tell you when the battery is getting low. It also has a plastic blade to help reduce the damage you may get from nicks shaving in uneven surfaces. But for me the plastic blades do not cut close enough when it comes to shaving my head in the shower. So I use this one for other areas while I have another water resistant one with metal blades that I use for my head.
For the past 10+ years, I've used a Andis cordless trimmer (2 or 3).
For the price, this Hatteker trimmer is the best bargain out there, & I would say are equal in quality, to the higher price competitor's.
