In an electric vacuum cleaner, in a suction air passage provided between a nozzle unit having a nozzle and an electric blower for producing a suction air flow, a separator for separating dust from the suction air flow is arranged. In the separator, a dust collection chamber for collecting the separated dust is provided. The separator is fitted with an exhaust tube having an outlet, fitted with a filter, formed in the peripheral surface thereof so that the suction air flow is exhausted out of the separator through the exhaust tube to the downstream side of the suction air passage. The separator is fitted with a cleaning member having a brush for cleaning the filter. When the cleaning member is moved with the brush keeping contact with the filter, the dust that has settled on the filter is raked off. The cleaning member is moved through manual operation, with a motor, or by the suction air flow.

The cleaning member is moved through manual operation, with a motor, or by the suction air flow. ss; each compression spring is received in the member receiving recess of the respective upward extended plate; each press member is a T-shape member that includes an outer ring integrally formed with a pivot section, the outer ring is formed with an annular recess for securing the compression spring, the pivot section has a distal end formed with an annular groove and an inclined guide face; the cleaning body includes an elongated plate, a glass scraper, and a brush, the elongated plate has a first side formed with a scraper clipping groove and a second side formed with a brush clipping groove, and has a mediate section formed with four member passing holes for passage of the rivet members, the glass scraper is a plate formed by soft plastic material, and has an inner edge secured in the scraper clipping groove of the elongated plate, the brush consists of multiple plastic threads, and has an inner edge secured in the brush clipping groove of the elongated plate. plit brush sections provides a gap between said split brush sections of said third brush, so that the distal end of one arm is not connected to the distal end of the other arm. 4. A toothbrush as claimed in claim 2 wherein said gap between said split brush sections is on an angle with respect to said handle so that said split brush sections overlap when said toothbrush is moved along the line of teeth to be cleaned. locking member from the second end so that the cavity can fit onto a protrusion of the locking member when the bed is stretched to an in-use position where the base rods are positioned substantially on a plane; thus, the safety device prevents folding of the bed caused by unexpected force. The cavity is disengaged from the protrusion for allowing displacement of the base rods by means of lifting the second end of the tube. locking unit controls the gap between the end of the bronze strings of the brush roller and the hot-cell floor surface to be cleaned by rotating the fan-shaped adjusting nut engaged with the adjustable bolt in a clockwise or counter-clockwise direction, and wherein fastening the fan-shaped adjusting nut in a clockwise direction lowers down both the housing and the primary suction unit relative to the hot-cell floor surface and makes the end of the bronze strings of the brush roller to be in contact with the floor surface. 6. A remote-controlled mobile cleaning apparatus as defined in claim 4, wherein the adjustable bolt engaged with the upper holder primarily passes through the upper boss of the adjusting holder downward, and secondarily the central opening of the fan-shaped adjusting nut prior to being finally inserted into the lower boss of the adjusting holder, thus completing the adjustable locking unit. 7. A remote-controlled mobile cleaning apparatus as defined in claim 6, wherein the adjustable locking unit controls the gap between the end of the bronze strings of the brush roller and the hot-cell floor surface to be cleaned by rotating the fan-shaped adjusting nut engaged with the adjustable bolt in a clockwise or counter-clockwise direction, and wherein fastening the fan-shaped adjusting nut in a clockwise direction lowers down both the housing and the primary suction unit relative to the hot-cell floor surface and makes the end of the bronze strings of the brush roller to be in contact with the floor surface. 8. A remote-controlled mobile cleaning apparatus as defined in claim 3, wherein the adjustable locking unit controls the gap between the end of the bronze strings of the brush roller and the hot-cell floor surface to be cleaned by rotating the fan-shaped adjusting nut engaged with the adjustable bolt in a clockwise or counter-clockwise direction, and wherein fastening the fan-shaped adjusting nut in a clockwise direction lowers down both the housing and the primary suction unit relative to the hot-cell floor surface and makes the end of the bronze strings of the brush roller to be in contact with the floor surface. 9. A remote-controlled mobile cleaning apparatus as defined in claim 1, wherein said flexible suction unit comprises: a suction nozzle having a predetermined length; a flexible hose connected to the suction nozzle; a connection hose extended from a control valve and connected to the primary collection unit; and a control valve to control the operation of said flexible suction unit, wherein said control valve connects the flexible hose and the connection hose and is fixedly mounted to the outer side of the housing. 10. A remote-controlled mobile cleaning apparatus as defined in claim 3, wherein said primary collection unit comprises: a storage case to collect radioactive waste debris sucked either through the primary suction unit or through the flexible suction unit, wherein said storage case has a circular plate at its lower part by which said storage case is sat in the interior of the housing; a sealing cap covering the top of the storage case completely by fastening a plurality of clamps mounted on the outer surface of the storage case; a perforated conduit pipe fixed concentrically at a bottom center hole of the sealing cap; and a cylindrical ceramic filter to primarily filter sucked radioactive waste debris, wherein said cylindrical ceramic filter encircles the perforated conduit pipe concentrically. 11.
