Adaptation and installation: The N30 Pro robot vacuum cleaner is for straightforward setup with no complex debugging required. It is ready to install, matches the machine structure, and helps ensure stable operation from the start. Cleaning performance: The roller brush is designed to rotate at speed while the machine is running, deeply touching the ground to effectively pick up dirt such as dust, debris, and hair. It works on wood floors, tiles, and shortpile carpets to keep floor surfaces clean. Antihair entanglement: The unique roller brush structure prevents hair from tangling, reducing the drop in suction power and cleaning efficiency caused by hair buildup. If hair attaches, it is easy to clean by simply removing the roller brush. Tool maintenance: The design is userfriendly, allowing manual disassembly and installation of the roller brush without any tools. This greatly saves time on accessory replacement and enables even firsttime users to get started quickly. Use scenarios: 1) Daily cleaning across homes with multiple floor types (wood, tile, and shortpile carpet) to maintain a spotless floor. 2) Homes with hair or debris, where easy rollerbrush maintenance helps sustain suction and cleaning performance. 3) users or quick setup when moving to a home, with hassle, tool installation and maintenance.
