Electric washers can be more convenient than their gas-powered peers in some circumstances. Plus, you don’t have to worry about gas fumes.

Pros of Electric Pressure Washers

Electric pressure washers do not produce harmful emissions. If you had to, you could use one indoors—though you would want hearing protection and a reliable way to remove the water.
An electric engine means you don’t have to worry about oil changes and other maintenance tasks.

Cons of Electric Pressure Washers

An electric pressure washer simply cannot produce the power of a gas-powered model. If you need to clean a large or especially dirty area, an electric pressure washer will take much longer to complete the job. (And you may not see the results you hoped for.)
Because they require a power outlet, electric pressure washers are not as portable as gasoline versions.
