Vacuum cleaners are the most used household appliances among other maintenance tools in your cleaning closet. There are various types of vacuums, including corded, cordless, and even robot vacuum cleaners. Today, technological innovations have made it possible for brands to manufacture smart cleaners that can be controlled with your smartphone. But no matter how fancy the gadget, you must still avoid the following common mistakes while using a vacuum cleaner: Do not vacuum wet surfaces Liquids coming in contact with electrical appliances is just a disaster in the making. Because water conducts electricity, you can damage the motors instantaneously or even experience minor electrocution. Regular vacuum cleaners are not designed to suction up liquids or other oddly shaped objects. There are, however, special wet-dry vacuum cleaners that are specifically designed to pick up water and other liquids. Commonly referred to as shop vacs, you can safely use these smaller-sized cleaners to clear up puddles and spills from most surfaces in and around the house. Not using the proper attachments Vacuum cleaners these days come with a ton of fancy attachments and accessories designed for specific tasks. For example, beater bars and roller bar accessories are ideal for cleaning heavy-duty carpets.
