Power-on-demand vacuums connect to a power tool for dust extraction and shut off automatically when the tool shuts off. - They have an outlet on their operating panel for plugging in power tools, so that the vacuum will run only when the power tool runs. - They're used for collecting dust from cutting, sanding, drilling, and grinding tools. - These vacuums also function as wet/dry vacuums for cleaning dust and dirt or liquid spills. - Specialty shop vacuums are used in specific applications, such as collecting dust from power tools or removing powders and chips from workers' clothing. - They include machines such as dust extractors for preventing dust buildup around machinery and wall-mount vacuums that won't take up floor space. - Other specialty vacuums are designed to handle specific materials, such as ash or slurry.
