Do You Know? The durability and lifespan of your office carpet depend on how well you maintain it. Commercial carpets’ lifespan will likely be reduced if they are not cleaned often and completely; as a result, businesses will have to replace the carpet earlier than necessary and at a significant cost.

We’ve created this comprehensive guide to the cleaning process to help you keep your business carpet in top condition. We explore a range of various carpet cleaning methods, balancing their benefits and drawbacks to help you make an informed choice. Keep reading to learn some myths and mistakes about carpet cleaning.

Which Method is Best for Carpet Cleaning?

Below are 4 types of carpet cleaning techniques:

1. Hot Water Extraction Cleaning

The dirt and particles are removed from the carpet using hot water under high pressure in the hot water extraction cleaning procedure. The built-up dirt particles in the carpet are forced out by rushing hot water under high pressure through its fibres.

The cleaning solution is put to the carpet surface and left for a time to allow it to absorb into the carpet fibres before the hot water runs through the carpet. Once the pressured hot water has been injected into the carpet for a while, the dirt particles start to emerge.


  • Extremely effective in removing stains on carpets.
  • One of the most comprehensive cleaning techniques available.
  • Breaks down germs while cleaning and produces less waste.
  • Environmental benefits over other techniques.


  • It takes longer than other cleaning methods and is time-consuming.
  • The carpet must be left untouched while drying because it might take a while.
  • Incorrect drying will result in the growth of bacteria in the carpet.
  • Hot water extraction equipment is loud, thus it can only be utilised during specific hours in some sectors.

If you have a deep-pile carpet that has to be cleaned immediately, hot water extraction can be the preferable option.

2. Dry Carpet Cleaning (Absorbent Compound)

This method involves mixing a gentle, natural cleaning solution with a tiny amount of water, detergent, and a solvent that is safe to use. The cleaners will then cover the entire carpet with the mixture. This will eventually form clumps like sawdust to clean spots and germ clusters. These aggregates function as tiny sponges that break down and take up dirt. When the clumps are swept out, the carpet surface is cleaner.


  • This technique doesn’t require any drying time.
  • Cleans completely in a short amount of time.
  • Strongly advised for commercial carpet.


  • This technique employs scent-producing chemicals that can be hard on carpet.
  • It may also result in dust accumulation.
  • The effectiveness of dry carpet cleaning in removing stains is inferior to that of other techniques.

As this technique just cleans the surface of a carpet, it is not considered as a “deep clean.” If you are looking for regular carpet cleaning then this is the best option.

3. Bonnet Carpet Cleaning

Carpets are cleaned with a bonnet machine during this cleaning method. The revolving bonnet-shaped head of the machine resembles a towel. The bonnet cleaning method concentrates on the carpet’s surface.

The cleaning solution is applied to the carpet surface by the revolving bonnet of the machine, which then removes both the cleaning solution and the dirt and debris from the carpet fibres.


  • Reduced drying time owing to reduced moisture.
  • Effectively handles high-traffic regions.
  • Cost-effective carpet cleaning technique.


  • Only offers a superficial amount of cleaning.
  • Swirl traces may be left.
  • The cleaning products include colours and brighteners.
  • After cleaning, sticky residue is frequently left behind.

Most often, hotels and other venues where they want to clean the carpet without interfering with guest convenience utilise the bonnet cleaning method.

4. Encapsulation Carpet Cleaning

Due to the identical techniques and extremely low moisture requirements, dry cleaning and the foam encapsulating cleaning procedure are similar. It also contains unique cleaning agents of its own.

The brush works on the carpet while dispersing the specialised foam across it, where it swirls into foam and bubbles. All of the grime, food stains and other difficult-to-remove stains on the carpet will eventually disappear. After that, you may remove the carpet fibres by lifting them with a strong vacuum cleaner equipped with counter-rotating brushes.


  • After utilising this cleaning technique, no waste is left behind.
  • Less likely to immediately become dirty again, or carpets stay cleaner for longer.
  • This technique uses a little amount of water, preventing harm to workplace electrical equipment.
  • Moreover, the drying time for the carpet is quick.


  • It is not recommended for extremely filthy or discoloured areas.
  • It requires thorough vacuuming to remove crystallised dirt.

The low-moisture technology allows for a quick and minimally invasive carpet cleaning process. Hence, carpets may be quickly put back to use. This is a fantastic commercial carpet cleaning technique that works wonders to preserve the surface of carpet with heavy foot traffic.

Carpet Cleaning Mistakes to Avoid

Regular and effective cleaning of carpets is essential for every office. Even while you may believe that you are using the proper techniques, you might be making some common carpet cleaning mistakes.

One of the best examples is scrubbing the carpet in the wrong way. If you are using hard-bristled brushes then it can damage the fibres of your carpet. And the worst part is; if the scrubbing untwists the fibres of the carpet then it can lead to tearing. This will make the carpet even harder to clean.

Professional Carpet Cleaning Myths

For companies or property owners, installing carpets is an investment that is both cost- and time-effective. Those who invest in carpeting want to ensure that they are caring for it in a way that will enable them to retain it in good condition for as long as possible. As a result; some office owners prefer commercial cleaners.

Yet, there are several office owners or individuals who believe in popular commercial carpet cleaning myths like professional cleaners are expensive or regular cleaning will damage the carpets etc.
