Chief Steamer Triangle Brush. The triangle brush is the go-to brush for carpet cleaning, especially in a car. The shower head output of steam disperses hot steam over the carpeted or fabric surface and makes quick work of dirt and many stains. The brush has heavy-duty nylon bristles, clips to hold a cleaning towel, and has a lock-in setting and a swivel setting for easy maneuverability. This brush stands up to heavy-duty use and is very well made.
