What happens to the dirt left behind ???
No Method removes 100% of the dirt and dirty water
So what happens to what's left behind
VLM uses agitation to clean with and usually dries in 1-2 hours. Dirt gets encapsulated in a detergent and crystallizes after drying and leaves no sticky residue
HWE uses WATER PRESSURE to clean with and uses at least 5 times more water than VLM. HWE usually takes 2-5 hours to dry (if customer is lucky that day) and uses a prespray and detergent
The longer it takes to dry the more dirty water left behind. VERY TRUE !!!
So what happens to all that prespray detergent and dirt left behind after it eventually dries
WATER PRESSURE pushes dirt down deeper to the bottom of the carpet making it much harder to remove, (thicker carpet much more of a problem) does the dirt detergent prespray left behind dry and remain at the bottom of the carpet, does the prespray detergent remaining at the bottom of the carpet cause resoiling, does the dirt after drying just sit at the bottom of the carpet forever, in the worst case does the dirt wick up and cause dull dingy looking carpet, or does it all just magically disappear
So what happens to all the dirt, prespray and detergent left behind by HWE
The longer it takes to dry the more dirty water left behind
LESS water MORE agitation !!!
