[0097] The number of the suction nozzles 216 is preferably 4 or 5. Of course, the number of the suction nozzles 216 can be appropriately increased or decreased according to actual application requirements and structural changes. Each suction nozzle 216 is connected to the air outlet interface 215 through a branch pipe 217 in the working head 210.

[0098] The working brush head 213 may be, but is not limited to, a common rust removal brush head such as a wire brush head and a polishing cotton brush head.

[0099] Preferably, the air extraction hose 320 and the power transmission cable 310 are arranged in the same soft casing 300 .

[0100] The handheld terminal 200 further includes a dust cover (not shown in the figure), which is sleeved on a side of the working head 210 away from each working turntable 212 .

[0101] When not in use, the working head 210, the hand-held rod 220, the vacuum hose 320 and the power transmission cable 310 can be disassembled and placed in the water storage cavity 120 to reduce the floor space occupied by the portable multifunctional cleaning tool when it is stored.

[0102] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of the utility model rather than to limit them. Although the embodiments of the utility model are described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the embodiments of the utility model can still be modified or replaced by equivalents, and these modifications or equivalent replacements cannot cause the modified technical solutions to deviate from the scope of the technical solutions of the embodiments of the utility model.
