The vacuum cleaner is an apparatus that creates a partial vacuum and is used to suck up dust and dirt. It uses an air pump to create a vacuum, and it is used to clean floors, but it can also clean other surfaces. What a vacuum cleaner sucks into itself is collected into a dustbag or a cyclone and later disposed of.
With canister vacuum cleaners, the cleaning nozzle is placed at the end of a wand, and linked to the vacuum unit through a hose. This unit, or canister, contains the engine, filter and dust bags. It has wheels in order to be dragged by the user.
They generally have better suction and flow rate, which can mean easier and faster cleaning for your cleaning team. Canister vacuums are quieter than other types of vacuums, which can be helpful in quiet environments like hospitals.
