Many models have a power tool socket that switches the vacuum on automatically with the tool.It is used for renovation, sanding, wall chasing, drilling and woodworking. More corded tool buying guides are in Choosing Corded Power Tools.ImportantFine gypsum, cement and sanding dust quickly clogs a household vacuum filter and can damage the motor. A construction vacuum is designed for exactly this kind of dust. Selection criteriaPower, suction and airflowMotor power shows energy consumption, while cleaning performance depends on suction (vacuum) and airflow. Compare both figures when the manufacturer states them.Tank size and materialA small tank (15–20 l) suits carrying and short jobs; a large one (30 l and more) suits building sites and large volumes. Steel tanks are tougher, plastic ones are lighter and do not rust.Filters and filter cleaningFilter type, area and cleaning method matter. Automatic or semi-automatic filter cleaning keeps suction steady during long work.Dust class (L, M, H)The dust class shows how hazardous a dust the vacuum is designed for. Class L is for general dust, M for concrete, gypsum and wood dust, and H for the most hazardous dust. The class is confirmed by the manufacturer.Tool socket and hose diameterA built-in socket switches the vacuum on together with the tool. Check the hose diameter and adapters so they fit the dust ports of your tools.Wet and dry operationIf you need to pick up water or wet debris, choose a wet and dry model and follow the manual regarding the filter.WarningDo not use a standard construction vacuum for hot ash, flammable liquids or explosive dust. Use a model of the appropriate class for hazardous dust.
