Sweeper capable of avoiding liquid cleaning

The invention relates to the technical field of sweeping machines, in particular to a sweeping machine capable of avoiding liquid sweeping, which comprises a sweeping machine whole body, a driving mechanism, a PLC (programmable logic controller) and an anti-collision frame, and is characterized in that the driving mechanism is arranged at the bottom end of the sweeping machine whole body and extends downwards to be supported on the ground; a radar scanning positioning system; the liquid sensor is arranged on the peripheral surface of the bottom end of the whole sweeper; the PLC is arranged in the middle of the interior of the whole sweeper; when the whole sweeper is put into use, the whole sweeper can collect information about whether the swept ground has spread liquid or not through one or more liquid sensors arranged on the peripheral end face of the bottom end, and when the spread liquid exists, a PLC in the whole sweeper can control the whole sweeper to avoid the area; by means of the arrangement, the sit
