Hot Water Extraction |
Primary source for performance & can be regulated. |
Low with scrub wands. Medium with motorize heads. |
Primary source for performance. Nonionic & high alkalinity detergents perform the best at the expensive of villainous residue. Anionic & lower pH products offer less performance and not as much of villainous residue. Encapsulants are less cost effective, but offer positive residues. |
Normally is the fastest for cleaning heavily soiled carpet. |
Cost effective restorative cleaning. Lowest pile distortion. Superior results on removing villainous residues if proper selection is made on products. |
Physically strenuous. Possible drying issues. Possible chemical residue. More prone to wicking. Normally lowest aesthetic effect on interim cleaning. |
|
Absorbent Pad |
Low to medium, Synthetic pads and gliders cause less heat. Heat comes from friction. |
Primary source for performance. Cotton has highest agitation and best drying. Synthetic pads have less friction. Gliders will reduce friction, but will increase time. Encapsulant detergents reduce friction. |
Nonionic detergents perform the best at the expensive of villainous residue. Anionic products offer less performance and not as much of villainous residue. Using encapsulants are cost effective, and offer positive residues. Yes, effervescences is a plus too. |
[1]Normally is the fast for cleaning lightly soiled carpet. |
Normally the most cost effective results on moderately soiled carpet with fast drying times & little fatigue on the technician. |
Can be highest in pile distortions. Most if not all claims will go against the technician on pile distortions. Marginal results on removing villainous residues. |
|
Encapsulation |
Low |
High |
High, but is a non-surfactant technology. Works without bias to solubility, polarity, and particle size common to aqueous surfactant solutions. Polymers are similar to protectants. |
Very fast for cleaning lightly soiled carpets. |
The best in appearance retention. More cost effective than absorbent pad on lightly soiled carpet. |
You need cleaner carpet to start with. Not as effective on interim cleaning for elevator lobbies and transitions from hard surfaces. |
|
Dry Foam |
Heaters are not part of the normal package, but are optional. |
Varies and is very controllable. |
Low to Medium |
You can clean a hold lot of carpet fast with a large machine. |
Time & drying |
Varies depending upon agitation and heat. Poor results on removing villainous residues. |
|
Shampoo |
Low |
High, can correct pile distortions. Brand new brushes can make pile distortions if not properly broken in. |
Anionic products are the standard product. Using encapsulants detergents are cost effective, and offer positive residues. |
Low |
Agitation |
Drying times are slow and overwetting is possible. Poor results on removing villainous residues. |
|
Powder Absorption |
Low |
Medium to High depends upon brush selections. |
Low |
High |
Putting carpet back in service immediately after cleaning. Almost no bleeding problems. Uses the least amount of moisture. |
Time & Cost Poor results on removing villainous residues. Superior dry vacuuming equipment is necessary to remove powder. |
