The Rotobrush is a specialized tool used in air duct cleaning. It is a cylindrical brush attached to a flexible shaft that is inserted into the air ducts and rotated to clean the interior surfaces of the ducts.
The use of the Rotobrush can help improve indoor air quality by removing contaminants from the air ducts, which can circulate throughout the home. It can also help improve the efficiency of the HVAC system by removing built-up debris that can impede airflow.
