Vacuum trucks are specialized vehicles designed for suction and transport of liquids, sludges, or solids from underground or confined spaces. A vacuum truck, sometimes called a suction truck or vacuum pump truck, works by creating strong negative pressure to draw materials into a sealed tank for safe disposal or processing.

These trucks are widely used in municipal, industrial, and construction settings. A septic vacuum truck is commonly used for cleaning septic tanks, while a sewer vacuum truck is designed for sewer line maintenance and emergency response. For excavation projects, a hydrovac truck or hydro excavation truck combines high-pressure water with vacuum power to dig precisely without damaging utilities.

Vacuum trucks come in various capacities and configurations to suit different job requirements, offering reliable performance for waste removal, material recovery, and site cleaning tasks.
