Main brush: This is the core component of the vacuum cleaner, responsible for removing dirt and dust from floors. Over time, the main brush may wear out or accumulate debris, reducing its effectiveness, so timely replacement is recommended. Side brush: The side brush works alongside the main brush to sweep dust and debris from edges and corners into the cleaning path, ensuring thorough coverage. With regular use, side brushes can wear down and should be inspected and replaced as needed. HEPA filter: The HEPA filter helps capture fine particles such as dust and pollen, contributing to cleaner air emission. Filter efficiency diminishes over time, so periodic replacement is advised. Mop cloths: These are used for mopping functionality to help remove stubborn stains and residue from hard floors. With use, mop cloths can become soiled and worn, which may impact cleaning performance, so regular replacement is recommended. These replacement parts help maintain the cleaning performance and longevity of your robotic vacuum cleaner. For best results, regularly check the condition of these components and replace them as necessary.
