Improve cleaning efficiency: Replace the main brush head of the vacuum cleaner with dense and elastic bristles, which can go deep into the crevices to absorb dust, clean carpets and floors more thoroughly, and restore the cleanliness of the home. Reduce hair tangling: The aging brush head is easy to entangle hairs and affect the operation, so replace the anti-tangle design of the main brush head of the vacuum cleaner so that the hair is not easy to get tangled and ensure the continuous and efficient work of the vacuum cleaner. Reduce operating noise: the worn brush head is easy to produce abnormal noise when running, and the main brush head parts of the vacuum cleaner are highly compatible, running smoothly and quietly, and more comfortable to use. Protect the cleaning surface: Replace the main brush head of the vacuum cleaner with a soft and moderate material, which will not scratch the surface of the floor and carpet during cleaning, and prolong the service life of home decoration.
