Spring is right around the corner and many of us have started preparing for the return of warmer weather. There are various things we may be doing from picking out our spring flowers for planting, washing the grime of winter off our houses and cars, and preparing our decks for staining. One of the most useful tools to have for the new season is a pressure washer since they are versatile for both deck preparation and power washing various household items. However, there are a number of things that we must consider before investing in a pressure washer.


Things to Consider Before Buying a Pressure Washer

There are various things that individuals need to investigate before purchasing a pressure washer. One of the first topics you need to consider is what you plan on using the pressure washer for. Are you planning on simply cleaning your deck, patio furniture, or car? Are you planning on power washing your entire house or removing paint from your siding or stain from your deck? Once you have determined your need, you can begin to look at various models.


  • Grade/Type

Pressure washers come in several different levels. Consumer or homeowner level is for individuals looking more for the cleaning power of a pressure washer to conduct tasks such as washing their car, deck, or house. These units are not used regularly, but rather more as seasonal tools. They also only output cold water. Semi-pro models are more upgraded than consumer models and have a professional grade water pump. These units can be for consumer use, but are meant more for regular usage like if you power wash your house every weekend. They output only cold water as well. The professional units are meant for everyday usage as they are built to stand up to repeated heavy use. These models are as the name suggests more for professional power washers. They are capable of outputting cold, warm, and hot water.


  • Water Capacity

Every pressure washer comes with specifications that can help consumers decide if they will fit their needs. Two of those specifications related directly to the units water capacity. Each unit has a pounds per square inch (psi) water rating, which indicates how much pressurized power it outputs. The higher the pressure, the better the unit is at breaking down a heavy chemical bond such as paint vs. dirt build-up. In addition, units also have a gallons per minute (GPM) rating, which indicates the amount of water outputted. The larger the amount of water, the more area the pressure washer can cover.


  • Cleaning Power

One specification you should pay the most attention to is the cleaning units or power measurement. This is calculated by taking the PSI rating and multiplying it by the GPM value. Basically, what this indicates is how fast the unit will clean. The higher the value, the quicker this unit will breakdown dirt and paint.


  • Cost

As you can probably imagine, each level of pressure washer costs differently. Consumer varieties tend to cost around $100-$350, while semi-pro models costs around $400 and up. Professional models are the most expensive and cost anywhere from $550 and upwards. If you are only looking to do seasonal maintenance, then the $550 price tag might be a bit too much to swallow.


  • Brand

This is probably the least important consideration of all of them, but it is still noteworthy. Some brands tend to provide higher quality performance and better customer service support and therefore, brand should not be discounted when considering what model to purchase.


Electric vs. Gas Pressure Washers

Pressure washers come in two main types; electric and gas. Each has unique qualities that make them more proficient at certain tasks over the other. Let us look at each type and discuss their benefits and shortfalls.


  • Electric Pressure Washers

Electric pressure washers are plug in varieties that are usually less portable, but significantly quieter. They are less powerful than gas pressure washers so most jobs with these units can take longer. They come in various sizes that are capable of different pressure ranges usually from about 1,300 to 1,700 psi. In addition, electric pressure washers tend to cost much less than gas versions because they are typically used more for small jobs such as seasonal cleaning of patio furniture or decks.


  • Benefits

As we mentioned, electric power washers tend to be better suited for smaller jobs such as cleaning decks, patios, and outdoor furniture. They are much better at jobs that are intended for cleaning over paint or stain removal. They also tend to be lighter units since they do not have gas tanks and require very little maintenance. In addition, these units tend to cost less than gas-powered units.


  • Downsides

Since these units provide less pressure, they tend to take longer to clean and are usually less sturdily constructed. Another downside for electric pressure washers is that they are less portable since you need to be near a plug or have several extension cords.


  • Gas Pressure Washers

Gas pressure washers are gas-powered, tend to be much more portable, and are usually quicker at cleaning than their counterparts. However, they also tend to be much louder than electric pressure washers. They require regular gas fill-ups, where obviously electric units do not. Gas pressure washers also come in various sizes and costs vary depending on the size and power. They typically output water at pressures of 2,000 to 2,800 psi, which make these units better suited for jobs that require more power such as paint stripping rather than grime removal.


  • Benefits

Gas pressure washers clean much faster than electric units because they output more pressure. They are best suited for larger projects like removing stain from your deck, removal of tough stains like oil marks, or cleaning your siding.


  • Downsides

These units tend to be much louder than electric units and are quite heavy given the added gas tank. They also require regular maintenance and must be winterized since they tend to be stored in colder areas like the garage or a shed. In addition with gas pressure washers, individuals need to use more caution when operating as they output higher pressurized water, which can cause injury or damage if focused on one spot for too long. These units also tend to cost more than electric units.
