电源单元启动，发送开机命令；
显示单元接收开机命令；
驱动单元(主电机)开始通电运作，吸收单元(真空吸力)持续运转；清洁单元(地刷组件)通电运作；
1.开启缺水检测单元，2.开启滚刷堵转检测单元
启动湿拖模式；
接收单元执行命令，并发送给清洁单元(地刷组件)；
水泵启动，持续向滚刷喷水作业；
滚刷启动，持续转动。
驱动单元(主电机)吸收单元(真空吸力)将清洁液体回收至回收装置中；
设备正常运作，并上传至显示单元。
这种常规的步骤问题点：
滚刷与地面持续清洁作业中，水泵持续喷水,压力及水量会有逐渐减弱的现象，导致不能持续有效的喷水，工作一段时间后滚刷表面会附着一些脏物， 同时内表面也会开始聚集泥垢，这使得洗地机持续作业清洁效果下降。

步骤2：洗地机水泵启动预喷水工作模式，将储液装置中的水输送至喷头持续喷出，随后延时启动清洁单元的滚刷(根据不同机型能够对延时时长进行设定)，在管道内无水状态下，液体从出水端流至喷水端会有时间差，导致检测单元会检测到缺水，防止检测缺水误判，洗地机水泵启动预喷水工作模式持续喷水0.2-1S后，滚刷启动工作模式持续转动；
步骤3：滚刷启动工作模式后持续转动，吸收单元将液体回收至回收装置中完成洗地机工作前的预处理；
步骤4：启动湿拖模式；接收单元执行命令，并发送给清洁单元；洗地机水泵启动常规工作模式持续进行周期性喷水作业，喷水期间滚刷持续转动，能够延长喷水作业的时间，以及稳定出水水量及出水压力。间隔喷水减少一定的喷水量，防止喷水量过大，吸力回收不干净，引起地面存留水渍；
步骤5：驱动单元的吸收单元持续将滚刷上的液体回收至回收装置中，同时回收装置内设有红外感应机构，红外感应机构包括了红外感应接收器与红外感应发射器，红外感应发射器发射出可穿透回收装置内污水的红外线，红外感应接收器根据红外线的光强强度判断污水的干净程度，并根据干净程度通过驱动单元、清洁单元分别调节吸收单元的吸力与滚刷的转速实现变频调节；根据红外感应接收器的光强强度将污水分为轻度混浊、中度混浊与重度混浊，在轻度混浊的情况下，驱动单元将吸收单元的吸力调节为一档吸力、清洁单元将滚刷的转速调节为一档转速；在中度混浊的情况下，驱动单元将吸收单元的吸力调节为二档吸力、清洁单元将滚刷的转速调节为二档转速；在重度混浊的情况下，驱动单元将吸收单元的吸力调节为三档吸力、清洁单元将滚刷的转速调节为三档转速；且二档吸力、二档转速是一档吸力、一档转速的1.5-2倍，所述三档吸力、三档转速是一档吸力、一档转速的2.5-3倍；
根据回收装置内污水的干净程度实现对调节吸收单元的吸力与滚刷的转速实现变频调节，根据污水干净程度判断地面干净程度，在地面干净时保持低功率运行，能够有效的延长洗地机的续航，在地面较脏时立即提高洗地机的清洁效率；
步骤6：设备正常运作，并上传至显示单元。
所述电源单元启动用于发送开机命令，所述显示单元用于接收开机命令与驱动单元、吸收单元、清洁单元、接收单元的工作状态，所述清洁单元包括地刷组件、储液装置与回收装置，且地刷组件包括滚刷与水泵。
所述步骤2中洗地机水泵预喷水持续的时长为0.2S-1S。
所述步骤4洗地机水泵周期性喷水作业的时间范围为每1S-5S喷0.1S-0.5S。
所述缺水检测单元预设一个电压值用于判断，通过持续一定时间检测导 电体之间的储水容器内水的流体的电阻，将电阻值换算成电压值，来判断是否缺水，当测出导电体之间的储水容器内液体的电压值低于预设值就能判定有水，高于预设值认为他没有水，其缺水检测单元的检测步骤如下：
步骤A：开启缺水检测单元；
步骤B：持续检测一定时间后检测的电压值是否超过预设数值，超过预设数值则执行步骤C，未超过预设值则执行步骤D；
步骤C：地刷工作异常状态；传至显示单元，等待处理；
步骤D：地刷正常工作。
所述滚刷堵转检测单元通过预设一个采样电流数值，电流超过预设数值即为过载，过载即为滚刷堵转，且检测步骤如下：
S1：开启滚刷堵转检测单元；
S2：持续检测一定时间后检测的电流数值是否超过预设数值，超过预设值则执行S3，未超过预设值则执行S4；
S3：判定地刷工作异常，处于堵转状态；传至显示单元，等待处理；
S4：地刷正常工作。
具体操作方法如下：
按键启动洗地机，电源开通发送开机命令，显示面板显示开机，主电机开始运作持续的运转真空吸力。主电机两侧分别设有储液装置和液体回收装置。
清洁部件地刷组件开始运作，各检测单元随即开始工作。各检测单元检测异常会将异常反馈至显示单元，提醒使用者。检测无异常，正常工作进入下一步骤。水泵启动预喷水工作模式-持续喷水1S，其目的是预先喷水，起到以下作用：1.管道内无水状态下，液体从出水端流至喷水端会有时间差，导致检测单元检测缺水，防止检测缺水误判。2.使水管内储存满液体，缩短喷液等待时间。3.排空原水管内遗留的液体。4.打湿滚刷，让液体预先浸泡滚 刷，提高清洁效果。
滚刷在水泵预喷水后延时启动，延时时间可为1S；两者启动的间隔时间相差甚微。但启动顺序仍是先水泵后滚刷。地刷组件内滚刷与滚刷盖板及挡水板形成内部的密封空间，通过高速转动的滚刷与喷水的配合在密封空间内完成自身表面的冲洗和空间的清洁，由主电机持续的真空吸力将液体回收至回收装置内。
用户启动湿拖模式，接收单元执行命令，并发送给清洁单元(地刷组件)；地刷组件启动常规工作模式，水泵先喷水，滚刷持续转动。其中水泵喷水以周期持续喷水作业，即每隔2S喷水0.1S。其目的一方面延长喷水作业的时间，以及稳定出水水量及出水压力。另一方面间隔喷水减少一定的喷水量，防止喷水量持续过大，吸力回收不干净引起地面存留水渍。驱动单元(主电机)的吸收单元(真空吸力)持续将液体回收至回收装置中；设备正常运作，并上传至显示单元，直至使用者完成清洁作业。
工作原理：洗地机通过地刷组件内的水泵喷射液体与高速转动的滚刷配合，与地面摩擦，然后通过主电机的真空吸力将清洁地面表面的污水以及碎屑等吸到回收装置的污液箱内，而获得更好的清洁效果。
在进行湿拖模式下，驱动单元(主电机)持续运转吸收单元(真空吸力)的情况下；清洁单元(地刷组件)开始作业。通过地刷组件内的水泵和滚刷之间进行喷射液体的步骤及喷射时间的有效配合，将水泵的清洁液体持续有效的向滚刷喷射，使滚刷在工作状态下，一边清洁地面，一边完成自身的冲洗，保持自身清洁。利用主电机的真空吸力持续将污液转移到液体回收装置，持续有效的完成清洁作业。
以上显示和描述了本发明的基本原理和主要特征和本发明的优点,对于本领域技术人员而言，显然本发明不限于上述示范性实施例的细节，而且在不背离本发明的精神或基本特征的情况下，能够以其他的具体形式实现本发 明；因此，无论从哪一点来看，均应将实施例看作是示范性的，而且是非限制性的，本发明的范围由所附权利要求而不是上述说明限定，因此旨在将落在权利要求的等同要件的含义和范围内的所有变化囊括在本发明内，不应将权利要求中的任何附图标记视为限制所涉及的权利要求。
