The electric razor (also known as an electric dry shaver) has a rotating or oscillating blade. Its use typically does not require the use of [[shaving cream]], soap, or water. The razor may be powered by a small [[Electric motor|DC motor]], which is either powered by [[Battery (electricity)|batteries]] or [[mains electricity]]. Many modern-day models are powered using [[rechargeable batteries]]. Alternatively, some models use an electro-mechanical [[oscillator]] driven by an AC-energized [[solenoid]]. Some early mechanical shavers had no electric motor and had to be powered by hand.

The first electric razor was invented by John F. O’Rourke in 1898.<ref>{{cite web|url=https://worldwide.espacenet.com/maximizedOriginalDocument?ND=4&flavour=maximizedPlainPage&locale=en_EP&FT=D&date=18981227&CC=US&NR=616554A&KC=A|title=Patent No. 616554, J.

Usually, electric shaving machines use several round rotating shaving blades or a horizontally shaver’s foil and cutter block technology.<ref>{{cite web|url=https://www.ub.rwth-aachen.de/go/id/phyk?#aaaaaaaaaaaphyo|title= Patent des Monats Januar: Der Rasierer|publisher=RWTH Aachen University|access-date=1 October 2019}}</ref>
