Cleaning machines are devices used to clean surfaces such as floors, walls, windows or other objects. There are different types of cleaning machines, such as high pressure cleaners, floor cleaning machines or even window cleaning robots. Pressure washers are usually electric or gasoline-powered and produce a powerful water jet to remove stubborn dirt and grime from surfaces. They are often used outdoors to clean patios, walkways or house facades, for example. Floor cleaning machines are used indoors to remove dust and dirt from floors. They can be designed for different floor coverings such as tile, laminate or carpet. Window cleaning robots are a relatively new type of cleaning machine designed specifically for cleaning windows. They operate automatically and are controlled by a remote control or smartphone app. Overall, cleaning machines can be a useful addition to the cleaning of premises and help save time and effort.
