Carpet cleaning is the process of removing dirt, stains, and allergens from carpets to make them look and smell clean. Here are some common methods of carpet cleaning:
1. Steam cleaning: This is the most common method of carpet cleaning. It involves using hot water and detergent to clean the carpet fibers. The machine uses high pressure to force the hot water and detergent into the carpet, and then sucks out the dirty water.
2. Dry cleaning: This method involves using a dry powder or foam to clean the carpet. The powder or foam is applied to the carpet, and then a machine with rotating brushes is used to work the powder or foam into the carpet.

Pressure cleaning, also known as pressure washing, is the process of using high-pressure water to clean surfaces that are difficult to clean using traditional methods. It's a highly effective way of removing dirt, grime, and stains from a variety of surfaces, including concrete, brick, stone, and wood.

Deep cleaning is a more thorough cleaning process that goes beyond the surface cleaning of a regular cleaning routine. It involves cleaning and disinfecting every nook and cranny of a living space, removing dirt, dust, grime, and bacteria that have accumulated over time.
