Omigo uses a maximum of 1200 watts when heating and performing a wash cycle; the seat heater alone uses 60 watts.
Make sure to only plug your Omigo into a grounded GFCI (ground fault circuit interrupter) electrical outlet. GFCI adapters can be found online or at your local hardware store.
If it is necessary to use an extension cord, only use those rated for a minimum of 15 amps with a 3-wire extension cord and a 3-blade grounding plug.
