Essentially, carpet cleaning procedures could be placed in one of two categories: wet cleaning or dry cleaning. Wet cleaning consists of hot water extraction and can involve cleaning with an absorbent pad. Dry carpet cleaning involves the use of chemical powders or foams applied by special machines with counter rotating brushes, pads or cylinders.
1. Wet cleaning
How it operates
Also called hot water extraction or steam cleaning, the carpet is initial pre-conditioned having a chemical reagent that liquefies soils and oil-based substances which may possibly be present inside the carpet fibers. Water is heated to a temperature close to its boiling point and pressurized, then injected in to the carpet. After about ten to 15 minutes, the option is extracted having a vacuum.
Require qualified assist together with your project?
Get quotes from top-rated pros.
Gets out soiling from deep down inside the carpet.
Permits the usage of higher temperatures, pressures and chemical concentrates.
Permits extended dwell instances for reaction of cleaning solvents.
Chemical reactivity facilitated by agitation with grooming tool or extraction wand.
Most extensively utilised method.
Recommended by carpet makers and industry cleaning authorities and pros
Fairly lengthy drying time, but this can be lowered together with the use of effective equipment by competent technicians.
High priced equipment usually necessary for maximum efficiency.
Relatively high price components.
2. Cleaning with an absorbent pad
How it performs
This carpet cleaning approach can also be normally identified as bonnet cleaning and is most generally utilized for routine light maintenance. It may also be utilised for regular carpet cleaning. The carpet is initial vacuumed, and then a chemical remedy is sprayed on to it using a hand pump or electric sprayer. The resolution is permitted to keep around the carpet for a appropriate dwell or reaction time.
The absorbent pad or bonnet, which looks like a towel, is placed on the drive block of a rotary floor machine and spun over the carpet surface at 100 to 300 rpm. This action serves to impregnate the carpet fibers with all the chemical answer after which pick it up together with the soils afterward.
Quickly, very simple and cheap.
Fantastic results with lightly soiled carpets.
Only cleans the leading one-third of carpet fibers, incapable of reaching deeper down.
Leaves dirt and chemical substances to accumulate at the bottom of your carpet fibers.
three. Dry cleaning with an absorbent compound
How it works
A powder which has been mixed with unique solvents and cleaning agents is spread over the carpet, and after that worked in to the carpet fibers having a machine fitted with counter-rotating brushes. The powder absorbs soils inside the carpet fibers. Following it is allowed to set on the carpet for ten to 15 minutes, it is vacuumed up.
Extremely straightforward system with no particular technical instruction required.
Really rapid drying, it generally only requires about 20 minutes before the carpet may be back in service.
Powder could be trapped in plush pile carpets and left to develop up over time.
May cause excessive dust build-up in the dwelling.
Unable to clean deep down in to the carpet.
4. Dry foam or rotary shampoo method
How it performs
A cleaning agent is applied to the carpet to help suspend dirt and debris inside the carpet, that is then whipped into foam and worked into the carpet fibers with all the rotating brushes of a unique machine. Soon after a quick dwell time, the foam is extracted with a vacuum.
Quick, easy to apply and low-cost.
Rotating brushes deliver superb agitation.
Smaller level of moisture makes it possible for quick drying of carpet.
Unable to achieve thorough soil extraction beneath the surface in the carpet.
High temperatures generally not achieved.
Excessive wetting possible with equipment malfunction.
