HIGH POWERED HOT WATER EXTRACTION MACHINE. 
The noisy [but very effective  and expensive] machine we use to thoroughly Clean and rinse your carpets. The high pressure hot water extraction unit we use cleans much better because it heats water to a very high temperature and then Jets the cleaning solution into the carpet at high pressure. This helps break up the dirt, bacteria and pollens in the carpet. The machine then produces a huge vacuum volume to draw the dirt and chemicals out of your carpet. This is the only method of cleaning recommended by the world’s largest carpet manufacturer. Unfortunately (for us!) the machines are very expensive  over £35,000 for a kitted up unit!.

This method is also referred to as steam cleaning even though steam is not used. 

Some people believe that hot water damages your carpet, but this isn’t true.  This is also one of the methods my company uses.

Many companies own professional equipment - but a large number of employees don’t know how to use them.  You probably know someone who bought the newest computer on the market  but didn’t learn how to use it for a year or more.  The same is true with carpet cleaning machines.  The company may own good equipment, but the employees may not know how to use it correctly.  This is why it’s important that you choose your carpet cleaner carefully.

The best carpet cleaning companies are those that have been certified by the National Carpet Cleaners Association, known as the N.C.C.A. A carpet cleaning company cannot just get these certifications. The carpet cleaner must earn the certification through study, and the successful completion of formal, written examinations.
