As shown in FIG. 1, the vacuum cleaner 1, a so-called autonomous vacuum cleaner, and a robot cleaner according to the present embodiment. The vacuum cleaner 1 consumes the electric power of the secondary battery 6 mounted on the main body 5 and moves autonomously. As the vacuum cleaner 1 travels, it moves on the surface to be cleaned f, the so-called floor surface, of the area A to be cleaned as a cleaning place in the living room. The vacuum cleaner 1 moves around the surface to be cleaned f in the area A to be cleaned to perform cleaning. The vacuum cleaner 1 comprehensively moves the area to be cleaned A to perform cleaning. When the vacuum cleaner 1 finishes cleaning the surface to be cleaned f, it autonomously returns to the station 7 (also referred to as "homecoming") and waits for the next cleaning operation.

The vacuum cleaner 1 may be a non-autonomous type that can be connected to the station 7 and stored, for example, a canister type, an upright type, a stick type, or a handy type.

The station 7 can be installed on the surface to be cleaned f in the area A to be cleaned. The station 7 can smoothly connect or disconnect the vacuum cleaner 1. The station 7 has a so-called charging stand function. The station 7 includes a power cord 8 that guides electric power from a commercial AC power source, and a charging circuit 9 that converts an AC voltage supplied via the power cord 8 into a DC voltage to charge a secondary battery 6. ..

The vacuum cleaner 1 returned to the station 7 charges the secondary battery 6 while waiting for the next cleaning operation, for example. Therefore, the vacuum cleaner 1 can save the trouble of charging by the user and can cope with the sudden cleaning operation requested by the user.

FIG. 2 is a right side view of the vacuum cleaner according to the embodiment of the present invention.

FIG. 3 is a bottom view of the vacuum cleaner according to the embodiment of the present invention.

The solid arrow F in FIGS. 2 and 3 indicates the forward direction of the vacuum cleaner 1.

In addition to FIG. 1, as shown in FIGS. 2 and 3, the vacuum cleaner 1 according to the present embodiment includes a main body 5, a moving portion 11 for moving the main body 5, and a surface to be cleaned below the main body 5. A cleaning unit 12 for cleaning, a detection unit 13 for detecting an object to be detected around the main body 5, a control unit 15 for controlling the operation of the vacuum cleaner 1, and two units for supplying electric power to each part of the vacuum cleaner 1. It is equipped with a next battery 6.

Further, the electric vacuum cleaner 1 includes a storage tank 16 provided in the main body 5 for storing liquid, for example, water, and an electrolyzed water generator 17 that electrolyzes the water stored in the storage tank 16 to generate electrolyzed water. It includes a first supply unit 18 that supplies the liquid stored in the storage tank 16 to the outside of the main body 5, and a second supply unit 19 that supplies the liquid stored in the storage tank 16 to the inside of the main body 5. That is, the vacuum cleaner 1

The main body 5 includes, for example, a main body case 21 made of synthetic resin and bumpers 22 provided on the side surfaces of the main body case 21. The main body case 21 is the outer shell of the main body 5. The bumper 22 is provided on the side surface of the main body case 21.

The main body 5 has a flat cylindrical shape, in other words, a disk shape. The main body 5, which is substantially circular in a plan view, can suppress the turning radius at the time of turning to be smaller than other shapes. In a plan view, the main body 5 may have a shape like a square, or may have a shape like a Reuleaux Triangle, for example, a curve of constant width in which the width of the distribution is always constant. good.

The main body case 21 and the storage tank 16 cooperate with each other to define the outline of the main body 5 in a plan view. In the present embodiment, the main body case 21 and the storage tank 16 have an arc-shaped outline cut by a string in a plan view. The arc-shaped outer line of the main body case 21 and the arc-shaped outer line of the storage tank 16 are combined at each string to draw a circular outer line of the main body 5. Similarly, even if the main body 5 has a shape other than a circle, the outer line of the main body case 21 and the outer line of the storage tank 16 are combined to draw the outer line of the main body 5. It is preferable that the storage tank 16 is housed inside the locus drawn by the outer line of the main body case 21 when the main body 5 is made to make a super-credit turn (spin turn, neutral turn, counter-rotation turn).

The height of the main body case 21 and the height of the storage tank 16 are substantially the same. The height of the main body case 21 and the height of the storage tank 16 may be different. For example, the height of the storage tank 16 may be higher than the height of the main body case 21, and the storage tank 16 may protrude upward. Further, the height of the storage tank 16 may be lower than the height of the main body case 21, and the storage tank 16 may be recessed. Further, the height of the storage tank 16 may be lower than the height of the main body case 21, and the storage tank 16 may be mounted on the upper surface of the main body case 21. In such a case, the upper surface of the main body case 21 may have a step between a portion on which the storage tank 16 is mounted and another portion. Then, it is preferable that the heights of the upper surface of the storage tank 16 and the upper surface of the main body case 21 are substantially the same with the storage tank 16 mounted on the main body case 21.

The moving unit 11 includes a plurality of drive wheels 26, a plurality of electric motors 27 that individually drive the drive wheels 26, and a driven wheel 28 that supports the main body 5 on the surface to be cleaned f together with the drive wheels 26. There is.

Each drive wheel 26 transmits a force for moving the main body 5 to the surface to be cleaned f. Each drive wheel 26 rotates about an axis extending in the width direction (left-right width direction) of the main body 5 as a rotation center. The plurality of drive wheels 26 include at least a pair of drive wheels 26. The axles of the pair of drive wheels 26 are arranged substantially on the same line. The vacuum cleaner 1 can go straight and turn by a pair of drive wheels 26. The drive wheel 26 is pressed against the surface to be cleaned f by a suspension device (so-called suspension). The vacuum cleaner 1 may have an endless track instead of the drive wheel 26.

Each motor 27 independently drives each drive wheel 26. The vacuum cleaner 1 advances straight (forward or backward) by rotating the left and right drive wheels 26 in the same direction, and turns (turns right or left) by rotating the left and right drive wheels 26 in different directions. ). Further, the vacuum cleaner 1 adjusts the forward or backward speed by raising and lowering the outputs of the left and right drive wheels 26, and adjusts the magnitude of the turning radius by making the outputs of the left and right drive wheels 26 different. be able to.

The driven wheel 28 is arranged at a substantially central portion and a front portion of the lower portion of the main body 5 in the width direction. The driving wheel 28 is, for example, a caster. The driven wheel 28 turns in accordance with the forward movement, backward movement, and turning of the vacuum cleaner 1 to stabilize the movement of the vacuum cleaner 1. The center of gravity of the vacuum cleaner 1 supported by the drive wheels 26 and the driven wheels 28 is preferably arranged inside the triangle formed by the pair of drive wheels 26 and the driven wheels 28. As a result, the vacuum cleaner 1 can move stably.

The cleaning unit 12 cleans dust directly below the main body 5 and on the surface to be cleaned f around the main body 5. The cleaning unit 12 includes a suction cleaning unit 31 that generates negative pressure to suck dust on the surface to be cleaned f, and a wiping cleaning unit 32 that wipes or polishes the surface to be cleaned f below the main body 5. ..

The suction cleaning unit 31 includes a suction port 34 provided on the bottom surface of the main body 5, a rotary brush 35 arranged at the suction port 34, a brush electric motor 36 for rotationally driving the rotary brush 35, and a dust collector provided on the main body 5. A dust container 37 as a unit and an electric blower 38 housed in the main body 5 and fluidly connected to the dust container 37 are provided.

The air passage that reaches the suction side of the electric blower 38 from the suction port 34 through the dust container 37 is a suction air passage 39 that is fluidly connected to the suction side of the electric blower 38. The suction air passage 39 includes an upstream air passage 39u from the suction port 34 to the dust container 37, and a downstream air passage 39d from the dust container 37 to the electric blower 38.

Further, the air passage from the exhaust side of the electric blower 38 to the exhaust port of the main body 5 is an exhaust air passage 41 fluidly connected to the discharge side of the electric blower 38. The exhaust air from the electric blower 38 is exhausted to the outside of the main body 5 through the exhaust air passage 41.

The suction port 34 sucks dust together with air by the negative pressure generated by the electric blower 38. The suction port 34 is arranged on the front side in the forward direction F with respect to the wiping unit 32. The suction port 34 extends in the width direction of the main body 5. In other words, the opening width of the suction port 34 in the left-right direction is larger than the opening width of the suction port 34 in the front-rear direction. Since the bottom surface of the main body 5 faces and faces the surface to be cleaned f during autonomous movement, the suction port 34 collects dust on the surface to be cleaned f or dust scooped up from the surface to be cleaned f by the rotating brush 35. Can be easily inhaled.

The rotation center line of the rotary brush 35 is directed in the width direction of the vacuum cleaner 1. The rotary brush 35 comes into contact with the surface to be cleaned f when the vacuum cleaner 1 is placed on the surface to be cleaned f in a movable state. Therefore, the rotary brush 35 that is rotationally driven scrapes up the dust on the surface to be cleaned f. The scraped up dust is efficiently sucked into the suction port 34.

The brush motor 36 rotates the rotating brush 35 in the forward or reverse direction. The forward rotation direction of the rotary brush 35 is a rotation direction that assists the propulsive force of the vacuum cleaner 1 when moving forward. The reversing direction of the rotating brush 35 is a rotating direction that assists the propulsive force of the vacuum cleaner 1 when reversing.

The dust container 37 is a part of the suction air passage 39. The dust container 37 accumulates dust sucked from the suction port 34 by the suction negative pressure generated by the electric blower 38. The dust container 37 is an inertial separation such as a filter for filtering and collecting dust, and an inertial separation (a separation method for separating dust and air by the difference in inertial force between the straight air and the dust) such as centrifugal separation (cyclone separation) and straight separation (separation method for separating the dust and air by the difference in inertial force between the straight air and the dust). It is a separation device that accumulates dust. The dust container 37 can be attached to and detached from the main body 5. The dust container 37 has a lid that can be opened and closed. The user can remove the dust container 37 from the main body 5, open the lid of the dust container 37 to easily dispose of the dust accumulated in the dust container 37, and clean or clean the dust container 37. it can.

The electric blower 38 consumes the electric power of the secondary battery 6 to drive the electric blower 38. The electric blower 38 sucks air from the dust container 37 to generate a suction negative pressure. The negative pressure generated in the dust container 37 acts on the suction port 34. The main body 5 has an exhaust port that allows the exhaust of the electric blower 38 to flow out to the outside of the main body 5.

The wiping portion 32 is the bottom portion of the main body 5 and is arranged behind the suction port 34.

In the forward direction of the vacuum cleaner 1 (solid line arrow F in FIG. 2), the suction port 34 and the wiping cleaning member 43 are arranged in the front-rear direction, and the suction port 34 is arranged in front of the wiping cleaning member 43. That is, the wiping cleaning member 43 is arranged behind the suction port 34. Therefore, when the vacuum cleaner 1 advances, the suction port 34 moves ahead of the wiping cleaning member 43. Therefore, the wiping cleaning unit 32 wipes and cleans the surface to be cleaned after the dust is removed by the suction cleaning unit 31.

The wiping cleaning unit 32 wipes or polishes, for example, the surface to be cleaned f below the main body 5. The wiping cleaning unit 32 includes a wiping cleaning member mounting portion 45 to which the wiping cleaning member 43 can be attached and detached, and a wiping cleaning member 43.

The wiping cleaning member mounting portion 45 is fixed by attaching a sheet-shaped wiping cleaning member 43 using a hook-and-loop fastener, winding a sheet-shaped wiping cleaning member 43, or inserting a part of the wiping cleaning member 43 into an insertion port. It is a base to be used. The wiping cleaning member mounting portion 45 brings the wiping cleaning member 43 into contact with the surface to be cleaned f in a state where the vacuum cleaner 1 is placed on the surface to be cleaned f. The wiping cleaning member mounting portion 45 itself may also be detachable from the vacuum cleaner 1.

The wiping cleaning member 43 is a wiping cleaning sheet made of a fibrous material such as a woven cloth or a non-woven fabric. The wiping cleaning member 43 is a variety of hygroscopic cleaning tools such as a wiper sheet, a duster cloth, a rag, and a mop (a mass of fibers at the tip excluding the handle portion). The material of the wiping member 43 is natural fiber such as cotton, regenerated fiber such as cellulose, polyester fiber, polyamide fiber such as nylon 6, nylon 66 and nylon 46, and synthetic fiber such as polyolefin fiber such as polyethylene and polypropylene. is there. The wiping member 43 may be a sponge. Further, the wiping cleaning member 43 may integrally have a member made of a superabsorbent polymer (SAP). The super absorbent polymer is a so-called absorbent polymer, a superabsorbent resin, or a polymer absorber. The wiping cleaning member 43 integrally having a member made of a super absorbent polymer can retain a larger amount of electrolyzed water.

The wiping cleaning member 43 can be attached to and detached from the bottom surface of the wiping cleaning member mounting portion 45. When the vacuum cleaner 1 is placed on the surface to be cleaned f in a movable state, the wiping cleaning unit 32 comes into contact with the surface to be cleaned f. It is preferable that the wiping cleaning unit 32 is pressed against the surface to be cleaned f with a pressure such that the drive wheels 26 do not slip on the surface to be cleaned f. An elastic member such as foamed resin is provided between the wiping unit 32 and the bottom surface of the main body 5. This elastic member presses the wiping portion 32 against the surface to be cleaned f with a uniform pressure.

The wiping cleaning member 43 is also an aspect of the first supply unit 18 that supplies electrolyzed water to the outside of the main body 5. The wiping cleaning member 43 wipes the surface to be cleaned f with water in a state of being moistened with the electrolyzed water supplied from the electrolyzed water generator 17.

Further, when the electrolyzed water is supplied to the surface to be cleaned f without passing through the cleaning member 43, the cleaning member 43 can also wipe off the electrolyzed water sprinkled on the surface to be cleaned f.

That is, the wiping cleaning member 43 can be used for so-called water wiping, in which the electrolyzed water is moistened and the electrolyzed water is applied to the surface to be cleaned f, and the electrolyzed water sprinkled on the surface f to be cleaned is wiped off. It can also be used for so-called dry wiping. In other words, the vacuum cleaner 1 sprinkles or applies electrolyzed water containing hypochlorous acid to the surface to be cleaned f as it moves, and sterilizes the surface to be cleaned f.

Whether the wiping with the wiping cleaning member 43 is a dry wiping or a water wiping is determined by the amount of electrolyzed water sprinkled from the electrolyzed water generator 17 onto the surface to be cleaned f and the amount of electrolyzed water supplied from the electrolyzed water generator 17 to the wiping cleaning member 43. It depends on the amount of electrolyzed water. For example, if the amount of electrolyzed water supplied to the floor surface is very small, the electrolyzed water evaporates before the wiping member 43 is moistened. In such a case, the dry wiping by the wiping cleaning member 43 continues. If the amount of electrolyzed water supplied to the floor surface is large, the electrolyzed water does not evaporate completely and moistens the wiping cleaning member 43. In such a case, the dry wiping by the wiping cleaning member 43 will eventually shift from the dry wiping to the water wiping.

The detection unit 13 detects an object to be detected that approaches the main body 5 as the main body 5 moves, or an object to be detected that comes into contact with the main body 5. The detection unit 13 is provided in the main body 5 and has a camera unit 51 that captures an image of the surroundings of the vacuum cleaner 1, and the main body 5 is provided in the main body 5 and the main body 5 approaches an object other than the vacuum cleaner 1, that is, an object to be detected. It includes a proximity detection unit 52 for detecting that the image has been made, and a contact detection unit 53 provided on the main body 5 for detecting that the main body 5 has come into contact with an object other than the vacuum cleaner 1, that is, an object to be detected.

The camera unit 51 is provided in front of the main body 5 and photographs the traveling direction in front of the vacuum cleaner 1, that is, when moving forward.

The vacuum cleaner 1 may include, in addition to or in addition to the camera unit 51, a distance measuring device 55 that obtains depth information in the photographing range by a principle different from that of the stereo camera.

The proximity detection unit 52 is, for example, an infrared sensor or an ultrasonic sensor. The proximity detection unit 52 using an infrared sensor includes a light emitting element that emits infrared rays and a light receiving element that receives light and converts it into an electric signal. The proximity detection unit 52 emits infrared rays from the light emitting element, receives the infrared rays reflected by the object to be detected by the light receiving element and converts them into electric power, and when the converted electric power exceeds a certain level, the object to be detected is within a certain distance. Is detected before the main body 5 comes into contact with the object to be detected. The proximity detection unit 52 that uses an ultrasonic sensor detects an object to be detected by using ultrasonic waves instead of infrared rays.

The contact detection unit 53 is a so-called bumper sensor. The contact detection unit 53 is interlocked with the bumper 22 that cushions the impact on the main body 5 when the moving main body 5 comes into contact with the object to be detected. When the bumper 22 comes into contact with the object to be detected, the bumper 22 is displaced or moved so as to be pushed inward of the main body 5. The contact detection unit 53 detects the displacement or movement of the bumper 22 and detects that the main body 5 has come into contact with the object to be detected. The contact detection unit 53 includes, for example, a microswitch that is turned on and off by the displacement or movement of the bumper 22, an infrared sensor that measures the displacement or movement amount of the bumper 22 in a non-contact manner, and an ultrasonic sensor.

The secondary battery 6 stores the electric power consumed by each part of the vacuum cleaner 1 including the moving unit 11, the cleaning unit 12, the detection unit 13, the control unit 15, and the power supply unit 57 of the electrolyzed water generator 17. The secondary battery 6 supplies electric power to each part of the vacuum cleaner 1 including the moving part 11, the cleaning part 12, the detecting part 13, and the control part 15. The secondary battery 6 is, for example, a lithium ion battery and has a control circuit for controlling charging / discharging. This control circuit outputs information regarding charging / discharging of the secondary battery 6 to the control unit 15.

The storage tank 16 is a container for storing an aqueous solution such as water or salt water. The water stored in the storage tank 16 may be tap water. The storage tank 16 is preferably removable from the main body 5 in order to enhance the convenience of water supply. The storage tank 16 is provided with a lid that can be opened and closed. The lid of the storage tank 16 can be opened to easily supply water or salt water.

The electrolyzed water generator 17 electrolyzes water to generate electrolyzed water in which ozone is dissolved, or electrolyzes salt water to generate electrolyzed water in which hypochlorous acid (HClO, Hypochlorous Acid) is dissolved. Or generate. In Japan, according to the Water Supply Law, tap water that is easily available at home contains chlorine. The Japanese Waterworks Law stipulates that the chlorine concentration in tap water should be 1/10 ppm (mass millions, milligrams per liter) or more (Waterworks Law Enforcement Regulations based on Article 22 of the Waterworks Law (Ministry of Health, Labor and Welfare). Ordinance) Article 17, item 3). The electrolyzed water generator 17 can easily generate electrolyzed water containing hypochlorous acid by electrolyzing water containing chlorine such as tap water in Japan or an aqueous solution obtained by dissolving chloride. The chloride may be, for example, a salt that is easily available at home. That is, the aqueous solution obtained by dissolving chloride may be salt water. The electrolyzed water generator 17 includes a plurality of electrodes 61 including a positive electrode and a negative electrode, and a power supply unit 57 that supplies DC power to the plurality of electrodes 61 with the electric power supplied from the secondary battery 6.

For the electrode 61 of the electrolyzed water generator 17, a material that is difficult to dissolve in water, for example, titanium or platinum, is used. In order to promote electrolysis, the electrode 61 may be supported with a platinum group metal such as iridium, platinum, ruthenium, or an oxide thereof. Chemical species such as hydrogen peroxide, active oxygen, and OH radicals are generated in electrolyzed water. The electrode 61 is provided in the storage tank 16. The electrode 61 applies a direct current supplied from the power supply unit 57 to the water.

The power supply unit 57 appropriately adjusts the voltage of the DC power supplied from the secondary battery 6 and applies it to the electrode 61.

The electrolyzed water generator 17 may be a one-chamber type having no partition between the positive electrode and the negative electrode, or a multi-chamber type including a two-chamber type and a three-chamber type having a partition between the positive electrode and the negative electrode. It may be. The one-chamber type electrolyzed water generator 17 neutralizes the acidic ionized water generated on the positive electrode side and the alkaline ionized water generated on the negative electrode side to provide electrolyzed water containing an appropriate concentration of hypochlorous acid. Generate. On the other hand, the multi-chamber type electrolyzed water generator 17 generates acidic ionized water in a room containing a positive electrode and alkaline ionized water in a room containing a negative electrode.

In the multi-chamber type electrolyzed water generator 17, the amounts of acidic ionized water and alkaline ionized water used may become non-uniform, and there may be a burden of disposing of the remaining ionized water. Unlike the multi-chamber type, the one-chamber type electrolyzed water generator 17 does not have a burden of disposing of the remaining ionized water, and may be more convenient for the user than the multi-chamber type.

By the way, the inventors have diffused or sprinkled electrolyzed water having a hypochlorous acid concentration of 5 ppm or more on the surface to be cleaned with a supply amount of 1/10 microliter per square centimeter or more to the surface to be cleaned. It was found that f can be sterilized. Therefore, the electrolyzed water generator 17 electrolyzes water having a chlorine concentration of 1/10 ppm or more, that is, water compatible with tap water under the Japanese Waterworks Law, and electrolyzed water having a hypochlorous acid concentration of 5 ppm or more. Has the ability to generate. If it is difficult to generate electrolyzed water with a hypochlorous acid concentration of 5 ppm or more even if tap water is electrolyzed due to the low chlorine concentration of tap water, chloride, for example, salt should be added to tap water. Just melt it.

The vacuum cleaner 1 does not have to include the electrolyzed water generator 17. That is, the electric vacuum cleaner 1 may store the generated electrolyzed water in the storage tank 16 and use it for sterilizing the area A to be cleaned.

The first supply unit 18 supplies the electrolyzed water to the surface to be cleaned f at a supply amount of 1/10 microliter per square centimeter or more so that the electrolyzed water can be diffused or sprinkled. The first supply unit 18 supplies electrolyzed water to at least one of the wiping cleaning member 43 and the surface to be cleaned f. The first supply unit 18 supplies the electrolyzed water from the storage tank 16 to the surface f to be cleaned, the pipe 62 that guides the electrolyzed water from the storage tank 16, the first supply mechanism unit 65 that supplies the electrolyzed water from the storage tank 16 to the wiping cleaning member 43, and the storage tank 16. The second supply mechanism unit 66 is provided.

The first supply mechanism unit 65 directly supplies the electrolyzed water to the wiping cleaning member 43 to moisten the wiping cleaning member 43, while the second supply mechanism unit 66 sprinkles the electrolyzed water on the surface to be cleaned f and the surface to be cleaned f. Electrolyzed water can be indirectly supplied to the wiping cleaning member 43 via the above to moisten the wiping cleaning member 43.

The first supply mechanism unit 65 has a wetting supply port 71 that supplies electrolyzed water to the back surface of the wiping cleaning member 43, and is provided in the middle of the pipe 62 to cut off the supply and supply of electrolyzed water to the wetting supply port 71. It is provided with a first on-off valve 72 for performing the above.

There may be a plurality of wetting supply ports 71. For example, the wetting supply ports 71 are arranged in a row in the width direction of the main body 5, that is, in the width direction of the wiping cleaning member 43. The wetting supply ports 71 arranged in this way can moisten a wide range of the wiping cleaning member 43 with electrolyzed water. Further, the wetting supply port 71 may be an elongated flat opening having a long side extending in the width direction of the main body 5.

The first on-off valve 72 is a so-called solenoid valve. By opening the first on-off valve 72, the first supply mechanism unit 65 supplies the electrolyzed water by the height difference between the water level of the electrolyzed water in the storage tank 16 and the wetting supply port 71, that is, the head difference. The first supply mechanism unit 65 may include a pump for pumping the electrolyzed water in the storage tank 16 instead of the first on-off valve 72. Further, the first supply mechanism unit 65 may be simply a flow path through which the electrolyzed water in the storage tank 16 flows out, for example, a thin tube or an orifice. In such a case, the inner diameter of the thin tube or the orifice diameter is appropriately and preferably set in order to obtain the required supply amount (supply amount per unit time) of the electrolyzed water.

The second supply mechanism unit 66 provides a sprinkling supply port 73 for sprinkling electrolyzed water to the surface to be cleaned f, and a supply port 73 provided in the middle of the pipe 62 to cut off the supply and supply of electrolyzed water to the sprinkling supply port 73. It is provided with a second on-off valve 74 to perform.

The sprinkling supply port 73 is, for example, a nozzle capable of sprinkling electrolyzed water. Electrolyzed water is supplied to the surface to be cleaned f sandwiched between the suction port 34 and the wiping cleaning member 43. In other words, the first supply unit 18 is located between the suction port 34 and the wiping cleaning member 43 from the sprinkling supply port 73 located in front of the wiping cleaning member 43 and the wiping cleaning member mounting portion 45 in the traveling direction of the electric vacuum cleaner 1.
