We didn’t have a way to calculate the actual PSI, but instead, we devised a method to compare the relative pressures between the tested models. We started with a kitchen scale, accurate down to 0.05-ounce measurements, and placed it in a resealable plastic bag for protection from water. Then we used a dinner plate and duct-taped it to the bag to prevent sliding and without putting any extra pressure on the scale. To measure pressure, we sprayed each wand at the dish from a distance of 12 inches and recorded the readout in pounds.
1800 watt universal motor coupled with the 5 piston pump gives an output of 3600 cleaning units. With a maximum peak pressure of 1800 PSI and flow rate of 2.0 GPM. Once you take the ePX3000 out westinghouse pressure washers of its box, assembly is incredibly easy. There are plastic attachments that you just slide on to pre-cut rails within the main chassis, and there are locking tabs that keep them in place.
We later encountered this on future uses and it goes away after a minute or so of use, so it seems to happen by design. The only way to really avoid it is to switch to a gas-powered washer. In her role as Chief Technologist and Director of Engineering at the Institute, Rachel Rothman has overseen pressure washer testing for more than a decade. She has personally tested more than two dozen models in recent years.
Since power washing and pressure washing are used interchangeably in most cases and both have the power needed for residential use, we treated them as synonymous in this review. Karcher Plug ‘n’ Clean lets you insert and remove detergent without having to bother with filling a tank. However, you need to use Karcher’s proprietary pressure washer detergent bottles. With internal soap tanks you must clean out the tank before you’re ready to use the pressure washer normally. Say you fill the entire tank with soap but only use half of it to clean the concrete on your driveway.
If you have an extremely high velocity but not a whole lot of mass, you’ll punch through dirt but only in a tiny area. Too much mass and not enough speed means you’ll cover a giant area but get nothing done. Sometimes high GPM is better because the stains are mild and spread over a large Champion Power Equipment area. That’s why you get different spray tips- so you can adjust your water jet depending on what you’re cleaning. For vehicles and windows you don’t want more than 1500 PSI, and the nozzle shouldn’t be narrower than 25°. For concrete and stone you want at least 2000psi and a 15° nozzle.
The most basic method just includes a hose; for these, you need to figure out how to secure the bottle. Most electric models are light and use solid-plastic wheels appropriate for that application. Gas-powered models typically have larger wheels that are solid or have pneumatic-rubber tires. Pneumatic tires can provide extra shock absorption, though they also lose air over time. We have a model for every budget and every need – including electric and gasoline powered washers up to 4,400 PSI.
A gas pressure washer is one that uses gas instead of electricity for power. Sun Joe introduced another dirt battering electric pressure washer with the SPX3500. Unlike many other models which are fitted with universal motors, the Sun Joe SPX3500 comes equipped with a more than capable induction motor in order to achieve a quieter and long lasting machine. It comes with 4 quick connect nozzle tips to vary the water pressure according to your needs. Included among the 4 nozzles is a turbo nozzle that produces a circular spray pattern and increases the pressure for cleaning off tougher stains and dirt.
We’re a small team of woodworkers, engineers and contractors with a combined experience of over 20 years dealing with power tools and outdoor power equipment . I have a degree in mechanical engineering and together with my team, we use this medium to share our insights and recommendations with you. westinghouse pressure washers Though it not the longest of hoses, the 30 foot reinforced hose that comes with it ensures that you can cover a wide surface area while cleaning. The WEN PW31 comes with 5 quick connect nozzles that you can really use to cause any form of dirt around your home to flee without looking back.
