The clothes and the hat are relatively simple and convenient to replace, the universality is strong, and the hidden danger of disease transmission is small. However, the replacement of shoes is troublesome and embarrassing, and particularly, the common shoes are replaced under the condition of foreign personnel, so that foot diseases are hidden in the prior art. The cleaning mode that the sole cleaner cleans the soles of the entering personnel is adopted, so that a plurality of problems caused by shoe replacement are effectively solved. The existing cleaning machine comprises a cleaning belt type or a cylindrical brush roll type, and a bearing strip is arranged between the adjacent cleaning belts or brush rolls for a user to tread. Existing washers typically have a certain width and for narrower aisles there is no room for personnel to walk after the washer is installed. For a clean environment which can only come in and go out of the channel, the user can only step on the cleaning machine to pass through when the user needs to come out of the channel. To avoid that the washing machine does not perform an ineffective washing operation or that the washing water is carried away, it is often necessary to cover the washing area with a cover plate in the washing unit so that a person steps on the cover plate to pass. However, the cleaning machine in the prior art lacks the cover plate, and only one plate can be additionally searched for to cover the cleaning machine, so that the potential safety hazard of sliding of the cover plate exists; in addition, no separate sterilizing unit is provided in the existing cleaning machine, which cannot sterilize shoes or has poor sterilizing effect. For this reason, further improvements to existing washers are needed.
