 Truck-mounted equipment may be used where electricity is unavailable, but may be unsuited to premises distant from a driveway or road, and require hoses to pass through windows to reach the upper floors of a building. The hoses needed for truck-mount and professional portable carpet cleaning may present a trip hazard, and allow pets or children to escape through doors left ajar. Heated or air conditioned air can also be wasted when doors are left open for hoses. Truck-mounted carpet cleaning equipment minimizes the noise in the room being cleaned, but may cause noise and air pollution offensive to neighbors, and could violate anti-idling bylaws in some jurisdictions. However, truck-mounted cleaning is much faster than portable equipment , and the extra heat will dissolve more spots and stains, and more vacuum suction power will reduce drying times .
