Large Semi-Pro Electric Pressure Washer Buyer's Guide

Some large semi-pro electric pressure washers supply almost twice as much cleaning power as their other semi-pro counterparts.

The biggest advantage these have over a comparably powerful gas unit is you can use these inside.

Need to clean around animals or livestock? No problem. There are no Carbon Monoxide emissions.

Hate performing small engine maintenance? Don't worry about it; the electric motors hardly require any upkeep.

Axial Cam vs Triplex Pumps

Axial Cam Pump
The first difference between consumer and semi-pro units is a better pump. Instead of a cheap wobble pump, you get a axial cam or triplex plunger pump. Axial cam are direct drive pumps, meaning they spin at the same speed as the engine, which will wear down faster than a triplex pump.

Triplex Power Washer Pump
Triplex plunger pumps are the highest quality pressure washer pump, offering longer life and better performance. They also include a larger price tag, but if you intend to use your power washer frequently, it's well worth the expense. If the pump breaks down, you can get it rebuilt instead of getting a new washer.

Detergent Tanks
Pressure Washer Detergent
If you need to clean with detergents or pressure washers soaps, consider an on-board detergent tank. The other, lesser option is a siphon tube, which you place in a bucket of detergent and water.

The more efficient option is definitely on-board detergent tanks. A lot of cleaning projects, such as washing your siding, require additional detergent to get completely clean. Just add detergent to the tank, conveniently located on your pressure washer, and you'll be able to use it without having to stop and set up a separate bucket.

Electric Considerations
Some of these large electric pressure washers require a 20 amp circuit to run. You'll want to make sure your circuit box has one of these where you'll be cleaning otherwise you won't be able to use the washer.

These units come with GFCI (Ground Fault Circuit Interrupter) power cords. They are designed to protect people from severe or fatal electric shocks because they detect ground faults and interrupt the flow
of electrical current. Just make sure you have GFCI plugs.
