The premium crevice tool is almost 4" longer than the standard crevice tool's length, which makes this tool superior in getting to those tight, hard to reach places such as underneath and behind furniture. There are more air-vents on the side than the standard crevice tool making it capable of maintaining airflow for better pick up of dirt and debris when used underneath areas like cabinets and appliances. Continuous airflow is critical for cleaning results, making the 13" premium crevice tool perfect for helping you vacuum the places that need it the most.
