Hi
its just one of for slices that you need for effective cleaning. in the image each slice is in 1/4 but they can be greater or less depending on the method. so say with microsplitter the heat might not be much smaller and mechanical much larger. for me i go for large chemical and dwell time, emulsification is my thing matching the right matching the right hydrophobic molecule to dirt type. understanding how each product works is far more effective and makes the job so much easier than trying to force the issue. heat heat alone will never release the dirt fibre bond. once you have done this its just a mater of flushing the emulsified dirt away.
One of the most common questions asked by customers is "how long will it take for my carpet to dry" over wetting and long drying times are down to poor emulsification. if the dirt is not released then keep going over and over it will not do it.
regarding claims about heat only cleaning, sometimes something might look one way when really its not. customers dont always tell the truth about the history of their carpets. all homes have hard floor areas. customers might over use detergent in these areas and then that residue gets walked onto the carpet causing any dirt to stick to it. try and remove dirt from a car with just high temp water. or would you wash a wool jumper in high temp? when has anyone been on a training course and be shown a method thats based on heat only for carpet cleaning.
if dirt can not be vacuumed out of a carpet then its bonded to fibre. this requires surfactants to release.
High heat can damage a carpet. the only reason TMs can product high heat is for long hose runs. if the TM could not then the water would be cold when it reaches the wand. I know it can be confusing when you get great products like polti but thats a different environment and surfaces being cleaned. when grease and oil is in the environment then this can form a film over the fibre and then the dirt sticks to it, this is different to a bond. environmental factors play a massive part in good cleaning and the choice of method and products used.
