FIELD: process engineering.
SUBSTANCE: invention relates to self-contained mobile cleaner. User force can be evaluated proceeding from magnitude and direction of stretching force applied to air passage pipe. Cleaner casing can displace in response to user force. This allows the cleaner to displace independently. Besides, this cleaner can, always and precisely, detect the user actions without interference caused by obstacles using the said air passage pipes. Costs of production can be notably decreased. Displacements in all directions can be calculated with the help of Hall transducer and magnetic element.
EFFECT: minimised user control force, ruled out damages of cleaner components, caused by undue force.
