Position of the insertion port 33a in the front-rear direction Home. As a result, as shown in FIG. 2, the center of gravity Ga of the electric cleaner 100 is located near the lower portion of the cylindrical portion 22 a held by the user. Therefore, the load of the load applied to the finger of the user is reduced.

Moreover, in the electric cleaner 100, as shown in FIG. 3, the central axis Ax1 of the suction port 15 is arrange | positioned on the front extension of the central axis Ax2 of the retractable pipe | tube 20 mentioned later in plan view of the cleaner body 1. As shown in FIG. 4, the central axis Ax1 of the suction port 15 is arranged parallel to the central axis Ax2 below the central axis Ax2 of the telescopic pipe 20 in a side view of the cleaner body 1.

Therefore, the electric sweeper 100 is excellent in operability when the first handle 30 mounted on the rear portion of the telescopic pipe 20 is held and the suction port 15 is directed toward the floor surface side.

As shown in FIG. 2, the center axis Ax5 extending in the direction of the long hole serving as the user's finger insertion port 33 a is located on the rear extension of the center axis Ax1 of the suction port 15 of the cleaner body 1.

Therefore, the electric cleaner 100 is excellent in operability when the second handle 33 is held and the suction port 15 is directed toward the floor surface side.

In addition, if the electric sweeper 100 is used in an upright form, the center of gravity Ga of the electric sweeper 100 is on the floor surface side, rather than the hand, so it can be cleaned without the burden of the opponent, which improves the convenience .

As shown above, the electric sweeper 100 can be easily used regardless of whether it is a handheld type or an upright type.

In addition, the electric sweeper 100 operates telescopic pipes Since the trigger 39 of the locking / unlocking device 50 of 20 constitutes the first handle 30, the length adjustment of the telescopic tube 20 using the first handle 30 is extremely simple.

In addition, with the electric cleaner 100, since the operation button 31a is disposed on the upper surface of the base handle portion 30a constituting the first handle 30, the user can easily use the fingers of the hand holding the side of the first handle 30, which is simple. Electrical operation of the electric sweeper 100 is performed.

In the electric cleaner 100, a switch substrate 36 associated with the operation button 31 a is disposed in the first handle 30. In addition, since the switch substrate 36 is fastened to the rib 35 a provided on the lower side of the handle upper half 35 constituting the first handle 30, the switch substrate 36 has excellent mounting stability and reliability.

Moreover, in this electric cleaner 100, since the switch substrate 36 is covered with the electrically insulating plate frame portion 37b through the ribs 35a, it is less susceptible to electrical influence from the outside.

Moreover, in this electric cleaner 100, as shown in FIG. 6, the front-end part of the telescopic pipe 20 (pipe member 21) is provided with the buckled part 51. As shown in FIG. However, in a conventional electric sweeper (see, for example, Patent Document 1), a pipe member is fastened to the rear end portion of the sweeper body, thereby locking the protruding length of the pipe member.
