Operates on the sides of the body of the robotic vacuum, specifically close to walls, baseboards, and corners of furniture, gathering scattered dust and small debris, filling narrow areas that the main brush cannot reach, and reducing blind spots in household cleaning. Uses a side-sweeping structure that conforms to various hard floors and tile gaps, sweeping out tiny sand grains and dust embedded in crevices, preventing long-term accumulation of fine residues and maintaining floor cleanliness. Shares the cleaning pressure of the main roller brush, takes over corner cleaning tasks in different zones, completes waste collection in different areas, delays wear on the main components, and makes the overall cleaning process smoother. Easy to install and remove, requiring no complex tools, can be done by hand; convenient for daily cleaning of tangled hair and leftover debris, making future maintenance simple and time-saving, suitable for home use.
