Pressure washers have revolutionized the way people clean their homes and vehicles. These electric or gas portable devices release water at a very high pressure. Grime, dirt and other sticky materials are pulled off the target surface, and the flowing water washes the loose particles away. Pressure washing will clean the surface without damaging its original paint and texture. It is generally used outdoors to clean a variety of surfaces such as cars, RVs, patios, decks and external sidings among other things.
About the Company
You will find a wide selection of pressure washers in the market today. They differ in cleaning power, features, durability and price. Karcher is one of the oldest and most trusted names in the cleaning industry. The company was founded by Alfred Karcher in 1939. Although its initial foray was into airplane motors and cabin heaters, Karcher ventured into the cleaning industry in 1950 with the development of the first European hot-water pressure washer.
The company has grown exponentially since then. It has subsidiaries in 41 countries of the globe and earns 85 percent of its revenue internationally. It also has 16 distribution centers that are spread across most continents. Almost 40,000 service centers in 190 countries strive to offer quality customer service to millions of people. Karcher products have been part of several prestigious restoration projects as well, including St. Peter’s Square in Rome.
How do Karcher Pressure Washers Work?
As with most pressure washers, Karcher products also take in water from a regular faucet. Some washers have accessories that allow them to take in water from a standing source as well. An electrical motor circulates the water at high pressure and expels it through a nozzle that is attached to the other end of the hose. Expelled water extracts dirt and grime from most surfaces and washes them away.
Karcher has come up with innovative ways to make their machines more efficient and powerful. All Karcher X-range, Compact range, and eco!ogic, and EcoSilent range of pressure washers use specialized motors that are cooled by circulating water instead of a fan. The incoming water flows around the engine and cools it before escaping through the nozzle. This feature helps improve the performance and the life of the pressure washer. High efficiency Karcher cleaners help you achieve perfect results while conserving close to 80 percent of water.
Types of Karcher Pressure Washers
Karcher has spent billions of dollars on research and development to create pressure washers that are more portable, powerful and quiet. All Karcher products come with their own set of advantages and can be categorized into three major groups:

- Wheeled Karcher Pressure Washers – Wheeled pressure washers offer easy mobility. They are great choice for homeowners who plan to use the washer around their home and garden. Most units come with two chunky wheels in the rear. You can simply drag the unit to every part of the house.

The efficiency and cleaning power of a Karcher pressure washer is determined by two important factors – the volume of water that circulates through the machine each minute (GPM), and the pressure with which the water is expelled (PSI). Together, volume and pressure determine the efficiency with which the machine removes dirt and grime from target surfaces and the speed with which it washes the dirt away.
The K7 series includes the most advanced pressure washers with the best cleaning power. They can handle almost any type of cleaning job at your home. Once you buy the right accessories, you will have a machine that is efficient and easy to use.
