• Regularly lift the cover: After using it three or four times, open the roller brush cover to check the inside. It is recommended to use a small brush to sweep away the fluffy dust stuck on the inside of the cover plate in daily life. If it is not cleaned for a long time, a circle of furry things will accumulate on the edge of the cover plate, causing it to not be tightly closed.
• Hair removal: The inner groove of the roller brush cover is prone to entangling long hair. During each cleaning of the roller brush, use your fingers to pull out the hair strands from the groove of the cover. It is recommended to use a used toothbrush dipped in water to brush the grooves and patterns, dry them thoroughly, and then cover them to reduce adhesion next time.
• Direction verification: Before installing the roller brush cover, pay attention to the arrow or protrusion mark on the cover, which corresponds to the body. It is recommended to align the front end and insert it first before pressing the back end. Do not forcefully reverse it, otherwise the gap between the cover will become larger and the sound produced during operation will be uneven.
• Anti vibration gasket: If there is a slight clicking sound when using the roller brush cover, you can stick a small piece of thick double-sided tape or thin sponge at the four corners inside the cover plate. It is recommended to check if the gasket has hardened every six months. If it has hardened, tear it off and replace it with a new one to reduce the vibration of the cover plate during work.
• Foreign object inspection: When the roller brush cover cannot be closed, do not press it hard with force. First, check if there is any hard object stuck in the roller brush slot. Daily advice is to flip over the vacuum cleaner and shine a flashlight under the cover. It is common for children to insert small blocks or coins, which can be removed and covered.
