A "shop vac," short for shop vacuum, is a powerful cleaning tool designed for heavy-duty tasks. Unlike regular household vacuums, shop vacs can handle larger debris, liquids, and fine dust. They are commonly used in workshops, garages, and construction sites, making them ideal for cleaning up after projects or spills. Shop vacs typically feature a large canister to collect debris and a strong motor for suction. Many models come with various attachments, such as hoses and nozzles, to help reach tight spaces or tackle different types of messes. They are versatile and essential for both DIY enthusiasts and professionals.
