Solution Overview
Problem
Current sweeping robots cannot automatically clean their mops, requiring manual intervention which compromises the automated cleaning process.
Innovation Solution
A method and system for a self-moving cleaning device to align with a washing device, using a cleaning unit with a roller brush and water outlet to autonomously clean the mop, allowing for efficient and automatic mop maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the sweeping robot uses dry-cleaning or wet-cleaning mode to clean the floor, then the cleaning performance is maintained, but the mop accumulates dirt and dust requiring manual replacement or washing
Solution Approach 1:
The patent implements a self-service mechanism where the sweeping robot automatically returns to the washing device to clean its own mop. The washing device includes a cleaning unit with a roller brush that rotates to scrape dirt from the mop, and a water outlet that sprays cleaning liquid. This automated self-cleaning system eliminates the need for manual mop maintenance while maintaining continuous cleaning performance.
2Extent of automation
If the sweeping robot cannot automatically clean the mop, then the automated cleaning function is limited, but manual cleaning intervention is required which compromises the automatic sweeping effect
Solution Approach 1:
The system enables the sweeping robot to autonomously perform mop cleaning by returning to the washing device. The cleaning unit automatically applies cleaning liquid and uses the rotating roller brush to remove dirt from the mop surface. This complete automation eliminates manual intervention time and extends the automated cleaning function to include both floor cleaning and mop maintenance.
Solution Approach 2:
The washing device performs preliminary cleaning actions by spraying cleaning liquid onto the mop before the roller brush scrapes the dirt. This pre-wetting action softens accumulated dirt and makes it easier to remove, enhancing the overall cleaning efficiency and completing the automated maintenance cycle.
3Extent of automation
If a cleaning unit with roller brush and water outlet is added, then automated mop cleaning is achieved, but the device complexity increases
Solution Approach 1:
The patent merges the water outlet and roller brush cleaning mechanisms into a single integrated cleaning unit. The water outlet sprays cleaning liquid onto the mop while the roller brush simultaneously scrapes the dirt away. This combination of washing and mechanical scraping in one unit achieves automated mop cleaning while minimizing the increase in device complexity.

Function Achieved in This Case
Enables fully automated floor cleaning and mop cleaning without human intervention, improving the efficiency and reducing the need for manual maintenance of the cleaning robot.
Implementation Method 1
a water outlet configured to spray cleaning liquid in a direction facing the first mop
Implementation Method 2
cleaning the first mop using a cleaning member of the cleaning unit

AI summary
The present invention involves a washing device and a cleaning method for cleaning self-moving cleaning devices. The cleaning method includes: moving the self-moving cleaning device towards the washing device, and causing a first side of the self-moving cleaning device to be aligned with the washing device, wherein the self-moving cleaning device includes a mop; and moving a mop to a location over a cleaning unit of the washing device, and cleaning the mop of the cleaning member of the cleaning unit, including, during a first period, causing the cleaning unit in a first direction over the first side; and during a second period, causing the self-moving cleaning device to move in a second direction different from the first direction.
