The size of pressure washer best for cleaning a 2-story house is a heavy-duty or extra heavy-duty pressure washer used for everyday commercial purposes. These expert-grade pressure washers deliver around 2800 psi and higher at 3 to 4 GPM.
When searching for the perfect pressure washer for cleaning a 2 story house from the ground floor, you must stay away from a low PSI pressure washer. Cleaning the sidings of a house is one task a homeowner will have to do at least once a year.
Aside from making the house look unkempt, all the dirt, dust, and grime piled up over time may attract bugs, dust mites, and mold. Pressure washers are a must-have for outdoor cleaning and they are known to be very good at getting rid of dust, mud, and dirt from buildings, surfaces, and even vehicles. This remains one of the reasons why people tend to like and want them.
Note that the power and pressure of pressure washers are measured by pounds per square inch (psi) or gallons per minute (GPM). PSI is a unit of pressure expressed in pounds of force per square inch of area. It is commonly used to measure the pressure of gasses (pneumatic pressure) or liquids (hydraulic pressure).
In square inch units, 1 psi is equivalent to roughly 6895 N/m2. Meanwhile, GPM (Gallons per Minute) refers to the amount of water that is coming from the machine. Have it in mind that pressure washers with higher psi and GPM will clean better and faster, and can be more expensive than low-rated units.
Agreeably, washing a 2 story house is a tough job, and the most ideal pressure washer for this duty will have to be gas-powered and duly equipped with a heavy-duty engine. A gas pressure washer with a high GPM rate will surely produce a high flow rate and this will increase the rate at which you’re doing your washing.
To do a good cleaning job, your pressure washer will have to give out above 2800 PSI at 3-4 GPM. Note that an electronic pressure washer may as well do the job but it will take a bit longer to complete your job. Have it in mind that cleaning a 2 story house is an energy-intensive task that can only be done efficiently by leveraging the right heavy-duty, gas-powered pressure washer.
