Vacuum cleaners and accessories clean surfaces in commercial and industrial workplaces. Wet/dry vacuums pick up debris or liquid spills at construction sites and industrial workshops. Commercial upright vacuums clean hard floors and thick carpets. Backpack vacuums are worn on your back to move with you through multiple hotel rooms or long corridors. Critical-area vacuums pick up hazardous materials, fine dust particles, and potent compounds in laboratories and cleanrooms. Handheld vacuums are small and lightweight for cleaning stairs, furniture, and car interiors. Canister vacuums have a lightweight cleaning wand attached to a canister that can be wheeled or carried along while cleaning. Vacuum accessories, attachments, and parts adapt vacuum cleaners for specific applications and replace worn parts to maintain proper operation.
