While both involve the removal of dirt and debris, there are some important differences between commercial and residential cleaning. Commercial cleaning typically involves specialized cleaning techniques and machines. It is often more detailed and thorough than residential cleaning and is usually done on a regular basis. It is also often more expensive, since the necessary skills and equipment are typically more sophisticated and require more time. Residential cleaning typically involves general cleaning techniques, such as vacuuming, mopping, dusting, and wiping down surfaces. People often hire residential cleaners to do occasional deep cleaning of their homes. Since residential cleaners generally do not use specialized equipment and techniques, their services are usually less expensive than commercial cleaning services. In general, commercial cleaning is more intensive and typically requires more specialized equipment and training than residential cleaning. However, both types of cleaning are important for maintaining a healthy and safe environment.
