Pressure washers are extremely efficient when working outdoors. It can effectively remove paint, stains and mold on the surface of objects, and can also be used to clean decks, streets and other places. Faced with the huge product lineup on the market, how to choose the perfect pressure washer has become a difficult problem.
As a well-known high pressure washer manufacturer, BISON has a full range of high-pressure cleaning equipment, including electric, gas, hot and cold water types, as well as novel battery-driven products. Here’s a comprehensive guide to help you choose the perpect pressure washer.
Different types of pressure washers
Cold Water Pressure Washers
Cold water pressure washers are the most common type of pressure washers and are ideal for removing dirt, dust, mud, and loose paint. They are typically more affordable and easier to maintain than their hot water counterparts. Also, they are lighter, making them more portable and suitable for residential use.
Hot Water Pressure Washers
Hot water pressure washers are designed to handle tougher cleaning jobs. The hot water not only helps to clean surfaces but also sanitizes them, making these pressure washers perfect for areas where hygiene is paramount. They are especially effective at removing oil and grease stains.
Electric Pressure Washers
Electric pressure washers are quiet, lightweight, and easy to start. They are perfect for light-duty tasks such as cleaning cars, outdoor furniture, or small patios. As they do not emit fumes, they are also suitable for indoor use. However, their dependence on electricity can limit mobility.
Cordless Pressure Washers
Cordless pressure washers, much like their gasoline and diesel counterparts, deliver power and efficiency in a compact package. They are designed for mobility, ready to tackle rigorous cleaning tasks at a moment’s notice. Yet, what sets them apart is their whisper-quiet operation and lightweight design. Free from cords and fuel dependencies, these models offer an unmatched blend of user-friendliness and convenience, making them a top choice for those seeking a hassle-free cleaning solution.
Understanding The Basics: PSI and GPM
In the world of pressure washing, two major parameters stand tall amidst the array of specifications that can determine the effectiveness of your equipment. These two figures are PSI (Pounds per Square Inch) and GPM (Gallons Per Minute), and understanding their roles in pressure washing operations is crucial for all stakeholders in this industry, including professional pressure washer manufacturers, operators, and consumers alike.
Pounds per Square Inch (PSI)
PSI stands for Pounds per Square Inch, and it represents the pressure output of your cleaning equipment. Simply put, PSI is the force exerted by the water when it hits the surface you are cleaning. The higher the PSI rating of a machine, the more pressure it can produce.
Different cleaning chores would require different levels of PSI. Low PSI ratings (say around 1,000 to 1,500 PSI) might be ideal for softer, more delicate surfaces such as car exteriors or wooden decks to avoid causing damages. Conversely, higher PSI ratings (2,000 PSI and above) are suited for removing stubborn dirt and grime on concrete surfaces, brick walls, and other tough outdoor areas.
Gallons Per Minute (GPM)
On the other hand, GPM refers to Gallons Per Minute – it’s the metric used to measure the volume of water a pressure washer uses within a minute. This figure highlights the cleaning unit’s flow rate which is highly important as it determines how rapidly you can clean a specific area.
A higher GPM will enable you to clean large areas more swiftly as it distributes more water in less time, thus increasing overall efficiency. Therefore, tasks like washing large decks or a fleet of trucks would benefit greatly from a pressure washer with a high GPM rating.
Balancing PSI and GPM
The key to an efficient pressure washing operation is striking a balance between PSI and GPM. It’s crucial to choose a pressure washer that delivers enough pressure (PSI) to dislodge dirt and enough flow (GPM) to wash it away. For instance, a machine with high PSI but low GPM could effectively loosen dirt, but if it doesn’t have enough GPM, it may take longer to carry the loosened dirt away.
Having said that, remember to always pick a pressure washer based on the specific cleaning tasks you are planning to undertake. Every task requires a unique combination of PSI and GPM, and understanding this can help you make the most of your professional pressure washing operations.
How To Choose The Perfect Pressure Washer FAQs
It is typically recommended to use a pressure washer with at least 2000-3000 PSI when cleaning tough surfaces like concrete or brick.
To wash most surfaces, a PSI pressure of about 1000-3000 should be ideal for home use.
The main difference is that power washing uses highly pressurized steam to do the cleaning while pressure washing just uses unheated tap water, without the help of a heating element.
