Best Pressure Washer For 2 Story House: Full Buyers Guide

When it comes to cleaning the exterior of your house, few options are better than a pressure washer. Your home’s siding generally requires a thorough cleaning at least once a year due to an accumulation of grime, dust, and dirt. Besides making the house look dirty, this build-up can attract insects as well as mold and dust mites.

Pressure washers are usually available in either electric or gas-powered versions. Both are effective; however, the gas-powered option is best for a two-story house. This is because it is easier to transport and it can exert higher pressure to clean the upper floors.

There are countless pressure washers currently on the market that are available in a wide range of prices. While most of them are relatively effective at cleaning, not all of them will have sufficient capacity to clean the second story of your home. This requires more power and higher pressure, which implies that a better machine is needed for this purpose.

Why Use a Pressure Washer?

Over time, every house accumulates dirt and grime on its exterior surface. If this is not cleaned on a yearly basis, it can start to build up to highly undesirable levels. With a build-up of grime and dirt often comes an environment rife with vermin, mold, and insects. 

While manual cleaning is certainly an option, this takes considerable effort to achieve, especially if you are hoping to achieve a high degree of cleanliness for the exterior surfaces of your home. 

Besides being extremely time-consuming, manually cleaning your house’s siding can be an extremely physically demanding endeavor, requiring significant manual labor to achieve the desired results.

By using a pressure washer, you are able to significantly reduce the amount of time taken to clean the siding as well as the amount of effort required. The process of dusting, scrubbing, and hosing down the siding of your house is reduced to a simple act of pressure-spraying.

A pressure sprayer uses high-pressure water to remove any dirt, grime, dust, mold, and even loose paint on the house’s surface in a fraction of the time that would ordinarily be required to achieve the same results manually.

Types of Pressure Washer

Pressure washers are primarily available in one of two options. The first option is gas, while the other is electric. Both have their advantages and disadvantages; however, electric pressure washers are not best suited for use with a double-story house.

Firstly, because electric pressure washers make use of a power cable in order to function, the cable itself can present difficulties when moving the pressure washer around to clean the outside of your house. 

Electric pressure washers tend to produce a lower pressure level when compared to gas options, and so this also makes them a less suitable option for use in a double-story house. 

Gas pressure washers, on the other hand, do not require a cable, and they are equipped with their own high-powered motor. This also gives them the ability to produce high levels of pressure, sufficient to clean the second story of your house.

How To Choose A Pressure Washer

In order to find a pressure washer that performs sufficiently in cleaning the siding of your house, your best point of reference – besides knowing that a gas washer will ultimately help you to achieve the desired result as opposed to the electric option – is the pressure output of the machine, measured in pounds per square inch (psi), as well as the gallons per minute (GPM).

PSI is a unit measurement of pressure that is established by one pound of force that is applied to an area measuring one square inch. The gallons per minute (GPM) is another indicator and describes how many gallons of water flow from the pressure washer per minute of operation time. 

If a pressure washer features a higher psi level as well as a higher GPM, it will inevitably do a better and quicker job of cleaning what is required. 

The type of pressure washer that is required for a two-story home is one that is heavy-duty and able to deliver high levels of pressure. The minimum pressure required for cleaning the siding of a two-story house is 2800 psi, with a minimum GPM rating of 3.
