Professional equipment for accommodations cleaning: is it reasonable to purchase such appliances?

Cleaning process of both residential, commercial and office accommodations demand professionalism and special equipment using for achieving the best results. At present time the scientific progress offers more and more equipment but on the other hand such equipment is purchased by professionals mostly.
For instance, steam generating unit is among the key cleaning equipment. Such unit is applied for disinfecting surfaces once or twice a month. The equipment is rather expensive therefore purchasing it for home using becomes rather unreasonable. The same situation concerns industrial vacuum cleaners purchasing. They are powerful but cost a lot and demand much space.
Therefore people accept a compromise. They don’t waste money for such equipment but order green cleaning services. Experienced technicians remove mud and dirt from every corner using their professional equipment. Such service becomes more and more demanded for both residential and commercial accommodations while prices are reasonable enough.
