It includes a first supply unit 41 that supplies the stored electrolyzed water to the outside of the main body 31, and a second supply unit 42 that supplies the electrolyzed water stored in the storage tank 37 to the inside of the main body 31.

The main body 31 has a flat cylindrical shape, in other words, a disk shape. The main body 31, which is substantially circular in a plan view, can suppress the turning radius at the time of turning to be smaller than that of other shapes. In a plan view, the main body 31 may have a shape like a square, or may have a constant width figure having a constant width of delivery, for example, a Reuleaux Triangle. good.

The main body 31 includes, for example, a main body case 51 made of synthetic resin and a bumper 52 provided on the side surface of the main body case 51.

The main body case 51 and the storage tank 37 are defined in cooperation with each other by defining the outer lines of the main body 31 in a plan view. In the present embodiment, the main body case 51 and the storage tank 37 have an arc-shaped outer line cut by a string in a plan view. The arc-shaped outer line of the main body case 51 and the arc-shaped outer line of the storage tank 37 are combined at each string to draw a circular outer line of the main body 31. Similarly, even if the main body 31 has a shape other than a circle, the outer line of the main body case 51 and the outer line of the storage tank 37 are combined to draw the outer line of the main body 31. It is preferable that the storage tank 37 is housed inside the locus drawn by the outer line of the main body case 51 when the main body 31 is made to make a super-credit turn (spin turn, neutral turn, counter-rotation turn).

The height of the main body case 51 and the height of the storage tank 37 are substantially the same. The height of the main body case 51 and the height of the storage tank 37 may be different. For example, the height of the storage tank 37 may be higher than the height of the main body case 51, and the storage tank 37 may protrude upward. Further, the height of the storage tank 37 may be lower than the height of the main body case 51, and the storage tank 37 may be recessed. Further, the height of the storage tank 37 may be lower than the height of the main body case 51, and the storage tank 37 may be mounted on the upper surface of the main body case 51. In such a case, the upper surface of the main body case 51 may have a stepped step between a portion where the storage tank 37 is mounted and another portion. Then, it is preferable that the heights of the upper surface of the storage tank 37 and the upper surface of the main body case 51 are substantially the same in a state where the storage tank 37 is mounted on the main body case 51.

The moving unit 32 supports a plurality of drive wheels 55 that can be grounded to the surface to be cleaned f, a plurality of electric motors 56 that individually drive the drive wheels 55, and a main body 31 on the surface to be cleaned f together with the drive wheels 55. It is equipped with a driving wheel 57.

Each drive wheel 55 transmits a force for moving the main body 31 to the surface to be cleaned f. Each drive wheel 55 rotates about an axis extending in the width direction of the main body 31, that is, in the left-right width direction. The plurality of drive wheels 55 include at least a pair of drive wheels 55. The rotation axes of the pair of drive wheels 55 are arranged substantially on the same line. The vacuum cleaner 2 can go straight and turn by a pair of drive wheels 55. The drive wheel 55 is pressed against the surface to be cleaned f by a suspension device, a so-called suspension. The vacuum cleaner 2 may have an endless track instead of the drive wheel 55.

Each electric motor 56 independently drives each drive wheel 55. The vacuum cleaner 2 travels straight by rotating the left and right drive wheels 55 in the same direction, and turns by rotating the left and right drive wheels 55 in different directions. Going straight includes forward and backward. Turns include right turns and left turns. Further, the vacuum cleaner 2 adjusts the forward or backward speed by raising and lowering the outputs of the left and right drive wheels 55, and adjusts the magnitude of the turning radius by making the outputs of the left and right drive wheels 55 different. be able to.

The driven wheel 57 is arranged at a substantially central portion and a front portion of the lower portion of the main body 31 in the width direction. The driven wheel 57 is a circular rotating body, for example, a caster. The driven wheel 57 easily follows the forward, backward, and turning of the vacuum cleaner 2 and changes its direction to stabilize the traveling posture of the vacuum cleaner 2. The center of gravity of the vacuum cleaner 2 supported by the drive wheels 55 and the driven wheels 57 is preferably arranged inside the triangle formed by the pair of drive wheels 55 and the driven wheels 57. Therefore, the vacuum cleaner 2 can move more stably.

The cleaning unit 33 cleans the surface to be cleaned f below the main body 31. More specifically, the cleaning unit 33 cleans the surface to be cleaned f directly under and around the main body 31. The cleaning unit 33 includes a suction cleaning unit 58 that generates a suction negative pressure to suck dust on the surface to be cleaned f, and a wiping cleaning unit 59 that wipes or polishes the surface to be cleaned f below the main body 31. There is.

The suction cleaning unit 58 has a suction cleaning function. The suction cleaning unit 58 includes a suction port 61 provided on the bottom surface of the main body 31, a rotary brush 62 arranged at the suction port 61, a brush electric motor 63 for rotationally driving the rotary brush 62, and a dust collector provided on the main body 31. A dust container 65 as a unit and an electric blower 66 housed in the main body 31 and fluidly connected to the dust container 65 are provided.

The air passage that reaches the suction side of the electric blower 66 from the suction port 61 through the dust container 65 is a suction air passage 67 that is fluidly connected to the suction side of the electric blower 66. The suction air passage 67 includes an upstream air passage 67u from the suction port 61 to the dust container 65, and a downstream air passage 67d from the dust container 65 to the electric blower 66.

The air passage from the exhaust side of the electric blower 66 to the exhaust port of the main body 31 is an exhaust air passage 68 that is fluidly connected to the discharge side of the electric blower 66. The exhaust air from the electric blower 66 is exhausted to the outside of the main body 31 through the exhaust air passage 68.

The suction port 61 sucks dust together with air by the suction negative pressure generated by the electric blower 66. The suction port 61 is arranged on the front side in the forward direction F with respect to the wiping unit 59. The suction port 61 extends in the width direction of the main body 31. In other words, the opening width of the suction port 61 in the left-right direction is larger than the opening width of the suction port 61 in the front-rear direction. Since the bottom surface of the main body 31 faces and faces the surface to be cleaned f during autonomous movement, the suction port 61 collects dust on the surface to be cleaned f or dust scraped up from the surface to be cleaned f by the rotating brush 62. Can be easily inhaled.

The rotation center line of the rotary brush 62 is directed in the width direction of the vacuum cleaner 2. The rotary brush 62 comes into contact with the surface to be cleaned f when the vacuum cleaner 2 is placed on the surface to be cleaned f in a movable state. Therefore, the rotary brush 62 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 61.

The brush electric motor 63 rotates the rotating brush 62 in the forward or reverse direction. The forward rotation direction of the rotary brush 62 is a rotation direction that assists the driving force (propulsive force) of the vacuum cleaner 2 when moving forward. The reversing direction of the rotating brush 62 is a rotating direction that assists the driving force (propulsive force) of the vacuum cleaner 2 when reversing.

The dust container 65 is a part of the suction air passage 67. The dust container 65 accumulates dust sucked from the suction port 61 by the suction negative pressure generated by the electric blower 66. The dust container 65 includes a filter that filters and collects dust, and inertial separation such as centrifugal separation (cyclone separation) and straight-line separation (separation method that separates dust and air by the difference in inertial force between straight-moving air and dust). It is a separation device that accumulates dust. The dust container 65 is removable from the main body 31. The dust container 65 has a lid that can be opened and closed. The user can remove the dust container 65 from the main body 31 and open the lid of the dust container 65 to easily dispose of the dust accumulated in the dust container 65, or to clean or clean the dust container 65. it can.

The electric blower 66 is driven by consuming the electric power of the secondary battery 6. The electric blower 66 sucks air from the dust container 65 to generate a suction negative pressure. The suction negative pressure generated in the dust container 65 acts on the suction port 61. The main body 31 has an exhaust port that allows the exhaust of the electric blower 66 to flow out to the outside of the main body 31.

The wiping / cleaning unit 59 has a wiping / cleaning function. The wiping unit 59 is the bottom of the main body 31 and is arranged behind the suction port 61. The wiping unit 59 may be provided at the bottom of the main body case 51, or may be provided at the bottom of the storage tank 37 that defines the outer line of the main body 31 in cooperation with the main body case 51. In other words, the main body case 51 or the storage tank 37 corresponds to the main structure provided with the wiping and cleaning unit 59.

The wiping / cleaning unit 59 wipes and cleans, for example, the surface to be cleaned f below the main body 31. The wiping cleaning unit 59 includes a wiping cleaning member mounting portion 72 to which the wiping cleaning member 71 can be attached and detached, and a wiping cleaning member 71.

In the forward direction of the vacuum cleaner 2 (solid arrow F in FIG. 2), the suction port 61 and the wiping cleaning member 71 are arranged in the front-rear direction, and the suction port 61 is arranged in front of the wiping cleaning member 71. Therefore, when the vacuum cleaner 2 advances, the suction port 61 moves ahead of the wiping cleaning member 71. Therefore, when the suction cleaning unit 58 and the wiping cleaning unit 59 are simultaneously functioning, the wiping cleaning unit 59 wipes and cleans the surface to be cleaned after the dust is removed by the suction cleaning unit 58.

The wiping cleaning member mounting portion 72 is fixed by attaching a sheet-shaped wiping cleaning member 71 using a hook-and-loop fastener, winding a sheet-shaped wiping cleaning member 71, or inserting a part of the wiping cleaning member 71 into an insertion port. It is a base to be used. The wiping cleaning member mounting portion 72 brings the wiping cleaning member 71 into contact with the surface to be cleaned f while the vacuum cleaner 2 is placed on the surface to be cleaned f. The wiping cleaning member mounting portion 72 itself may also be detachable from the vacuum cleaner 2.

The wiping cleaning member 71 is a wiping cleaning sheet made of a fibrous material such as a woven cloth or a non-woven fabric. The wiping cleaning member 71 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 71 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 71 may be a sponge. Further, the wiping cleaning member 71 may integrally have a member made of a superabsorbent polymer (SAP, so-called absorbent polymer, highly absorbent resin, polymer absorber). The wiping cleaning member 71 integrally having a member made of a super absorbent polymer can retain a larger amount of electrolyzed water.

The wiping cleaning member 71 can be attached to and detached from the bottom surface of the wiping cleaning member mounting portion 72. When the vacuum cleaner 2 is placed on the surface to be cleaned f in a movable state, the wiping cleaning unit 59 comes into contact with the surface to be cleaned f. The wiping and cleaning unit 59 is preferably pressed against the surface to be cleaned f with a pressure such that the drive wheels 55 do not slip on the surface to be cleaned f. An elastic member such as foamed resin is provided between the wiping unit 59 and the bottom surface of the main body 31. This elastic member presses the wiping portion 59 against the surface to be cleaned f with a uniform pressure.

The wiping cleaning member 71 is also an aspect of the first supply unit 41 that supplies electrolyzed water to the outside of the main body 31. In other words, the vacuum cleaner 2 can wipe and clean the surface to be cleaned f with a wiping cleaning member 71 containing water. The wiping cleaning member 71 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 38. The surface to be cleaned f, which is wiped with electrolyzed water, is sterilized.

When the electrolyzed water is supplied to the surface to be cleaned f without going through the cleaning member 71, the cleaning member 71 can also wipe off the electrolyzed water sprinkled on the surface to be cleaned f.

That is, the wiping cleaning member 71 can also 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 2 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 71 is a dry wiping or a water wiping is determined by the amount of electrolyzed water sprinkled from the electrolyzed water generator 38 to the surface to be cleaned f and the amount of electrolyzed water supplied from the electrolyzed water generator 38 to the wiping cleaning member 71. 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 71 is moistened. In such a case, the dry wiping by the wiping cleaning member 71 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 71. In such a case, the dry wiping by the wiping cleaning member 71 will eventually shift from the dry wiping to the water wiping.

The detection unit 35 detects an object to be detected that approaches the main body 31 as the main body 31 moves, or an object to be detected that comes into contact with the main body 31. The detection unit 35 is provided in the main body 31 to capture an image of the surroundings of the vacuum cleaner 2, and the detection unit 35 is provided in the main body 31 so that the main body 31 approaches an object other than the vacuum cleaner 2, that is, an object to be detected. It includes a proximity detection unit 82 that detects that the main body 31 has been used, and a contact detection unit 83 that is provided on the main body 31 and detects that the main body 31 has come into contact with an object other than the vacuum cleaner 2, that is, an object to be detected.

The camera unit 81 is provided in front of the main body 31 and photographs the traveling direction in front of the vacuum cleaner 2, that is, when moving forward.

The vacuum cleaner 2 may include, in addition to or in addition to the camera unit 81, a distance measuring device 85 that obtains depth information in the photographing range by a principle different from that of the stereo camera.

The proximity detection unit 82 is, for example, an infrared sensor or an ultrasonic sensor. The proximity detection unit 82 that uses 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 82 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 31 comes into contact with the object to be detected. The proximity detection unit 82 that uses an ultrasonic sensor detects an object to be detected by using ultrasonic waves instead of infrared rays.

The contact detection unit 83 is a so-called bumper sensor. The contact detection unit 83 is interlocked with the bumper 52 that cushions the impact on the main body 31 when the moving main body 31 comes into contact with the object to be detected. When the bumper 52 comes into contact with the object to be detected, the bumper 52 is displaced so as to be pushed inward of the main body 31. The contact detection unit 83 detects the displacement of the bumper 52 and detects that the main body 31 has come into contact with the object to be detected. The contact detection unit 83 includes, for example, a microswitch that is turned on and off by the displacement of the bumper 52, an infrared sensor that measures the amount of displacement of the bumper 52 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 2 including the moving unit 32, the cleaning unit 33, the detection unit 35, and the control unit 36. The secondary battery 6 supplies electric power to each part of the vacuum cleaner 2 including the moving unit 32, the cleaning unit 33, the detection unit 35, and the control unit 36. 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 36.

The storage tank 37 is a container for storing water or salt water. The water stored in the storage tank 37 may be tap water. The storage tank 37 is preferably removable from the main body 31 in order to enhance the convenience of water supply. The storage tank 37 is provided with a lid that can be opened and closed. The lid of the storage tank 37 can be opened to easily supply water or salt water. The storage tank 37 is provided with a water amount detection unit 86 that detects the amount of water in the storage tank 37.

The electrolyzed water generator 38, for example, 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, milligram 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 38 can easily generate electrolyzed water containing hypochlorous acid by electrolyzing water containing chlorine such as tap water in Japan or salt water. The electrolyzed water generator 38 includes an electrode 87 including a positive electrode and a negative electrode.

For the electrode 87 of the electrolyzed water generator 38, a material that is difficult to dissolve in water, such as titanium or platinum, is used. In order to promote electrolysis, the electrode 87 may be supported by 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 87 is provided in the storage tank 37.

The electrolyzed water generator 38 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 38 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 38 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 38, the amount of acidic ionized water and alkaline ionized water used may become non-uniform, which may cause a burden of disposing of the remaining ionized water.

The detection control unit 117 stores in the detection result storage unit 125 the detection result of the contact detection unit 83, that is, that the object to be detected has come into contact with the main body 31. The information stored in the detection result storage unit 125 can be associated with the environmental map information and used for optimizing the movement route in the autonomous movement of the vacuum cleaner 2.

The water amount detection unit 86 may be either a contact type or a non-contact type. The contact type water amount detection unit 86 is, for example, a float type that measures the water level based on the position of the float (float) provided in the storage tank 37 in the vertical direction, and detects the capacitance between the pair of electrodes to determine the water level. A known method such as a capacitance type for measuring can be adopted. The non-contact type water amount detection unit 86 can adopt, for example, a known method of measuring the water level using radio waves, ultrasonic waves, or light waves.

In addition, in the bed leaving mechanism of the second example to the bed leaving mechanism of the fourth example, the same reference numerals are given to the same configurations as the bed leaving mechanism of the first example, and duplicate description will be omitted.

FIG. 6 is a schematic view of a first example of the bed leaving mechanism of the vacuum cleaner according to the embodiment of the present invention.

By the way, when the wiping cleaning member 71 containing water typified by electrolytic water is left in contact with a floor material having hygroscopicity such as a wooden floor including tatami mats and flooring, that is, the surface to be cleaned f, the floor material Excessively absorbs moisture, or the wax applied to the flooring material is removed. If such a situation is left unattended, the floor material may be discolored or damaged.

Therefore, as shown in FIG. 6 in addition to FIGS. 2 to 4, the vacuum cleaner 2 according to the present embodiment has a bed leaving mechanism 75 of the first example capable of separating the wiping cleaning member 71 from the surface to be cleaned f. (Hereinafter referred to as "bed leaving mechanism 75").

The solid line in FIG. 6 indicates a state in which the wiping cleaning member 71 is separated from the surface to be cleaned f, and the alternate long and short dash line in FIG. 6 indicates a state in which the cleaning member 71 is in contact with the surface to be cleaned f. ..

The bed leaving mechanism 75 provides a space between the surface to be cleaned f and the wiping cleaning member 71 to separate the wiping cleaning member 71 from the surface to be cleaned f. The bed-leaving mechanism 75 includes an elevating mechanism 76 of the wiping cleaning member mounting portion 72 and a bed-leaving electric motor 77 for driving the elevating mechanism 76. The bed leaving mechanism 75 brings the wiping cleaning member 71 into contact with the cleaning surface f or separates the wiping cleaning member 71 from the cleaning surface f by moving the wiping cleaning member mounting portion 72 closer to or away from the surface to be cleaned f. To do.

The bed leaving mechanism 75 separates the wiping cleaning member 71 from the cleaning surface f when the main structure provided with the wiping cleaning unit 59, for example, the main body case 51 and the storage tank 37 is stopped at the cleaning surface f. In other words, the bed leaving mechanism 75 separates the wiping cleaning member 71 from the cleaning surface f when the relative speed between the wiping cleaning member mounting portion 72 and the surface to be cleaned f is zero.

The elevating mechanism 76 may employ various mechanisms that convert the rotational driving force of the bed-leaving electric motor 77 into a linear motion that moves the cleaning member mounting portion 72 in the vertical direction. The elevating mechanism 76 is, for example, one of a rack and pinion, a ball screw, a pulley device, and a link mechanism.

Then, as shown in FIG. 5, the autonomous movement control unit 116 of the vacuum cleaner 2 according to the present embodiment includes a bed leaving control unit 126 that controls the operation of the bed leaving electric motor 77 of the bed leaving mechanism 75.

The bed leaving control unit 126 switches and controls a state in which the wiping cleaning member 71 of the wiping cleaning unit 59 is in contact with the surface to be cleaned f and a state in which the wiping cleaning member 71 of the wiping cleaning unit 59 is away from the surface to be cleaned f.

The bed leaving control unit 126 determines whether or not the vacuum cleaner 2 is stopped based on the detection results of various sensors such as the detection unit 35 and the encoder, or the control signal of the movement control unit 121.

The vacuum cleaner 2 is stopped in a state in which the drive wheels 55 of the moving unit 32 are stopped based on the control of the control unit 36, and a state in which the vacuum cleaner 2 cannot move due to the idling of the drive wheels 55. , And at least one state in which the vacuum cleaner 2 is unable to move due to some obstacle. Further, the stop of the vacuum cleaner 2 includes at least one of a state in which the vacuum cleaner 2 is stopped waiting for the cleaning operation and a state in which the vacuum cleaner 2 is temporarily stopped during the cleaning operation.

Further, the determination as to whether or not the vacuum cleaner 2 is stopped may be established at the moment when the vacuum cleaner 2 is stopped, or the stopped state of the vacuum cleaner 2 is a predetermined duration, for example. It may be established when the vacuum cleaner 2 continues for 3 to 5 seconds, and may not be established when the stopped state is released before the predetermined duration elapses, that is, when the vacuum cleaner 2 starts to move. .. When the vacuum cleaner 2 has been stopped for a predetermined duration, the dead zone treatment is performed so that the vacuum cleaner 2 is determined to be stopped, so that the wiping cleaning member 71 frequently leaves the bed by the bed leaving mechanism 75. And the landing motion are suppressed.

When the main structure is stopped on the surface to be cleaned f, the bed leaving control unit 126 separates the wiping cleaning member 71 from the surface to be cleaned f, and when the main structure is moving on the surface to be cleaned f. Brings the wiping cleaning member 71 into contact with the surface to be cleaned f. In other words, when the relative speed between the wiping cleaning member mounting portion 72 and the surface to be cleaned f is zero, the bed leaving control unit 126 separates the wiping cleaning member 71 from the surface to be cleaned f, and the wiping cleaning member mounting portion 72 and the covering When the relative speed with the cleaning surface f is a non-zero value, the wiping cleaning member 71 is brought into contact with the surface to be cleaned f.

In the bed leaving control unit 126, even if the relative speed between the wiping member mounting portion 72 and the surface to be cleaned f is a non-zero value, if the main structure is retracted (the relative speed is a negative value), When the wiping cleaning member 71 is separated from the surface to be cleaned f and the main structure is advancing (relative velocity is a positive value), the wiping cleaning member 71 may be brought into contact with the surface to be cleaned f.

In this way, in the vacuum cleaner 2, by keeping the wiping member 71 containing water away from the surface to be cleaned f when stopped, the surface to be cleaned f absorbs excessive moisture or is applied to the surface to be cleaned f. It is possible to prevent the wax from being removed.

The vacuum cleaner 2 can dry the wiping cleaning member 71 by generating an air flow between the wiping cleaning member 71 and the surface to be cleaned f. The bed leaving control unit 126 drives the bed leaving electric motor 77 to separate the wiping cleaning member 71 from the surface to be cleaned, and then operates the electric blower 66 through the suction cleaning control unit 122. The electric blower 66 sucks in air through the suction port 61 and discharges air through the exhaust port of the main body 31. The vacuum cleaner 2 uses the intake flow or the exhaust flow of the electric blower 66 to generate an air flow between the wiping cleaning member 71 and the surface to be cleaned f. When the wiping cleaning member 71 does not need to be dried, the vacuum cleaner 2 may be provided with a louver in order to keep the intake flow or the exhaust flow of the electric blower 66 away from the wiping cleaning member 71.
