    Abstract: This invention provides an improved method and system for controlling a self-propelled floor cleaning vehicle characterized by the fact that the vehicle has excellent cleaning performance. This method is applied to a floor cleaning vehicle that follows a guidance line located on the floor. It detects the level of dirt or scratching present on the floor and it controls the running speed of the floor cleaning vehicle corresponding to the amount of the dirt or scratching detected. It is thus able to modify the cleaning and polishing/buffing operation in response to the amount of dirt or scratching on the floor.

    Abstract: In connection with a mounting device for sensors and pick-ups generally, serving as dust-detecting means for vacuum cleaners, in particular in the form of luminous diodes and phototransistors arranged adjacent the suction channel of the said vacuum cleaner, it is proposed to form at least one axial channel, leading from the inside to the outside, immediately adjacent the sensor, through which an air flow is passed due to underpressures or overpressures prevailing in the area of the sensor, which air flow acts to continuously clean the sensitive area of the sensor.

    Abstract: An electric cleaner for use in households and/or industry, is provided with a control system for running the blower of the motor cleaner at a constant speed in spite of the speed set by a control unit when dust has not been detected by a dust sensor, and to effect an increase in the speed of the blower motor up to the speed set by the control unit when dust has been detected, whereby the electric cleaner is capable of effecting a cleaning operation quietly with its operational properties being improved.

    Abstract: In connection with an optical indication and function monitoring unit for vacuum cleaners comprising optical dust detection means in the form of a luminous diode and a phototransistor provided adjacent the suction duct, and optical indication means for the user, it is proposed to provide, in addition to first delay means for the dust detection means, second delay means having a longer time constant and designed in such a manner that a third flashing luminous diode, which also lights up when the supply battery is nearly run down, is triggered when the dust indication does not operate for an extended period. Further, the pressure switch connecting the unit with the supply battery and responding to a vacuum condition generated by the associated vacuum cleaner is adjusted in such a manner that the whole unit is repeatedly connected to the supply battery when a sufficiently high dust level is reached in the dust bag of the vacuum cleaner so that at least one of the luminous diodes provided for the indication seems to flash.

    Abstract: The invention is concerned with pneumatic apparatus for removing fibres, dust and threads from industrial processes, particularly in the textile industry. In an arrangement in which there is a plurality of collecting heads each associated with a part of a machine from which dust, fibres or threads are likely to be emitted, each of these collectors leads into a common duct which in turn leads to a suction fan and filter.The suction pressure (or any other physical characteristic of the air in the duct which relates to the suction pressure) is detected, and a signal from this detector is compared with a signal corresponding to a desired suction pressure and the output signal from the comparator used to control the speed of the driving motor for the suction fan. In this way, the suction pressure in the duct approximates to a constant pressure, despite variations due to the build-up of material on the filter or other factors such as the opening and closing of dampers controlling the flow of waste material into the duct. Consequently, the fan speed can be set at an optimum value, instead of having to set it at a value which will ensure operation of the system under the worst conditions. Hence, a large energy saving is possible.

    Abstract: Disclosed is a cleaner. The cleaner according to an embodiment includes a main body, a suction device configured to suck dust outside the cleaner, a dust detection sensor including a light emitting element and a light receiving element disposed adjacent to the suction device, a dust container configured to store sucked dust through the suction device, and a processor configured to identify a dust inflow state and a dust amount of the dust container based on a voltage value output from the light receiving element, and control an operation of the cleaner based on the identified dust inflow state and dust amount, wherein the light emitting element and the light receiving element are disposed at an outside of the dust container in a direction toward an inlet of the dust container.
