Yes, Omigo does require an electrical outlet, operating on a standard 120 volts AC.
Omigo must be plugged into a GFCI outlet. A GFCI outlet is ground-fault circuit interrupter (outlet with an internal safety breaker, common in kitchens and bathrooms). If your outlet is not GFCI, you can purchase an adapter online or at your local hardware store.
For those interested in installing a new outlet specifically for their Omigo, the optimum location when facing your toilet fixture is to the right side of the fixture underneath the toilet tank.
