Efficient cleaning: The main brush head is larger, covering a wide area to quickly remove dust, hair, and debris. This design helps improve cleaning efficiency for large cleaning tasks. Deep cleaning capability: Bristles or a special design enable the head to reach deep into carpets and floor gaps, effectively removing hidden dirt for thorough cleaning. Versatile compatibility: Most main brush heads are suitable for wooden floors, tiles, and carpets, reducing the need to change brush heads and increasing convenience during use. Debris gathering design: The shape and structure are engineered to gather debris together, making it easier for the vacuum cleaner to lift and preventing scattered debris during cleaning. Use case: Daily living room cleaning with mixed flooring and pet hair. The wide head covers more surface area on hard floors and helps lift hair from carpets in fewer passes, improving efficiency. Use case: Cleaning under furniture and along baseboards. The broad head and gathering design reach into tight spaces and collect debris in one pass, minimizing the need for repositioning. Use case: Large open areas with transitions between floor types. The head's crosssurface compatibility allows effective cleaning across wood, tile, and carpet without frequent brush head changes, saving time during large cleaning sessions.
