About the Karcher Brand​​​​

Alfred Karcher was one of four inventors and entrepreneurs.  When he was 23 years old, he completed his studies at the Technical University of Stuttgart, in 1924.  He worked first at his father’s agency, which he developed into an engineer’s office.  In 1935, he founded his own company, so that he could produce and market his own products in the field of heating technology.  

After World War II, the company turned its attention to products to be used every day.  Such as round stoves, small cookers, handcarts, and trailers for tractors.  Karcher made his breakthrough into the cleaning technology in 1950.  He developed the first European Hot Water High-Pressure Cleaner.  The design of the water heater proved to be so pioneering that it still forms the basis of all burners today.

 The range of products Karcher offers is extensive.  They offer products on a residential level as well as professional level.  They offer Electric, and gas pressure washers.  Push sweepers, Multi-functional vacuum cleaners, and a window cleaner.  

On the professional level they offer, hot and cold-water pressure washers, as well as trailers to hold them.  They have a portable hot water heater, and water treatment systems.  When it comes to floors, they offer scrubbers, sweepers, buffers and specialty equipment.
