Just a few years ago, extra-large electric power washers were often regarded as high-pressure water picks.
Now, with improved technology, these pressure washers can reach pressure ratings up to 2000 PSI.
They’re ideal for cleaning mid-sized surfaces including sidewalks, decks and patios. But, they still lack the strength to remove very stubborn stains or strip paint.
If you have medium-sized cleaning tasks around the house, extra-large electric pressure washers will be perfect for you.
Universal (or brush) motors are typically found in small, cheaper pressure washers and perform the job at a very inexpensive price. If you rarely use your pressure washer, you can save some money by purchasing an electric power washer with a universal motor. It just won’t last as long.
Induction (or brushless) motors, however, are typically used in larger, more powerful electric power washers. They typically last longer than universal motors. They also cost more. If you want an electric pressure washer that lasts, spend the extra few dollars and buy one with an induction motor.
Due to the larger size than their handheld counterparts, extra-large electric pressure washers have room for on board detergent tanks. This will save you time versus a siphon tube, which requires the use of an additional bucket for your detergent.
When you're cleaning really tough stains, the power of water alone is sometimes not enough. But with the addition of concentrated detergents,
cleaning mildew and mold from patios and brick is much easier.
Wobble/Axial vs Triplex Pumps
Wobble and axial cam pumps are found on cheaper pressure washers.
They are generally rated for between 60-100 hours of use. If you'll be using your washer occasionally this is fine.
In fact, with these pumps it's usually cheaper to buy a new pressure washer than it would be to replace the pump.
Triplex pumps are a higher 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.
