％のものを用いることが好ましい。On the other hand, in the main body 1 of the electric vacuum cleaner, an exhaust chamber 61 is formed behind the electric blower chamber 15, and an exhaust gas is formed in the upper rear part of the upper case 2b of the main body 1 of the electric vacuum cleaner. Room
An exhaust hole 62 communicating with an exhaust hole (not shown) of the electric blower 14 via the opening 61 is formed at the rear side of the upper case 2b. In the exhaust chamber 61, a high-performance filter 63 having a dust trapping property of 0.3 μm or more and 0.5 μm or less similar to that of the first auxiliary dust collecting filter 21 is 60% or more and 90% or less is provided. The second auxiliary dust collecting filter 64 is detachably arranged. The second auxiliary dust collecting filter 64 has a trapping ability of 50% lower than the trapping ability of the high-performance filter 38 of the first auxiliary dust collecting filter 21, for example, 0.3 μm or more and 0.5 μm or less. Use one. This is because the first auxiliary dust collection filter 21 captures a small amount of fine dust that is mostly captured by the dust collection bag 17 and not captured by the dust collection bag 17.
Almost no dust is mixed in the air flowing into the exhaust chamber 61, and the suction efficiency is reduced due to the decrease in air permeability due to the use of the high-capacity high-performance filter 21, and at the positive pressure side of the electric blower chamber 15. Since the positive pressure becomes high and the air flowing into the exhaust chamber 61 does not pass through the second auxiliary dust collecting filter 64 and is discharged together with fine dust collecting from the gap of the main body case 2 or the like, the problem becomes larger. 2 auxiliary dust collection filter 64
Is lower than the trapping ability of the first auxiliary dust collecting filter 21, for example, the trapping ability of dust of 0.3 μm or more and 0.5 μm or less is 50.
% Is preferably used.

ほつれることを防止できる。When the suction port 74, the hose 70, the extension tube 80, the suction port body 81, or the like is clogged with dust or the like during cleaning, the negative pressure on the suction side of the electric blower 14 increases, and this negative pressure is increased. Is detected by the pressure sensor 57 and the control means mounted on the circuit board 54 controls the drive of the electric blower 14 to have a high output for a predetermined time, for example, and is displayed on a display means such as a level indicator (not shown). And remove the blocking dust. Further, when the dust bag 17 is filled with the captured dust, the negative pressure on the suction side of the electric blower 14 also increases. Therefore, when the pressure sensor 57 detects an increase in negative pressure even though the dust is not blocked, the cleaning worker determines that the dust bag 17 is full and interrupts the cleaning. And replace the dust bag 17. Since the net-like body 34 is provided on the raised side of the high-performance filter 36 whose one surface is raised, it is possible to prevent the hand or the like from touching the high-performance filter 36 when replacing the dust collection bag 17, for example. It is possible to prevent the constituent charged fibers from fraying.
