  • a vacuum cleaner is a household appliance that sucks in small garbage or dust in a manner that uses electricity to suck air and fills the dust bin in the product, and is generally referred to as a vacuum cleaner.
  • Such a vacuum cleaner may be divided into a manual cleaner in which the user directly moves the cleaner to perform cleaning, and an automatic cleaner in which the user performs cleaning while driving by themselves.
  • the manual cleaner may be classified into a canister-type cleaner, an upright cleaner, a handy-type cleaner, and a stick-type cleaner, depending on the type of cleaner.
  • canister-type vacuum cleaners were used a lot in household cleaners, but recently, hand-held vacuum cleaners and stick cleaners, which are convenient to use by providing a dust container and a cleaner body, are increasingly used.
  • the canisty type vacuum cleaner is connected to the main body and the suction port by a rubber hose or pipe, and in some cases, it can be used by inserting a brush into the suction port.
  • the Hand Vacuum Cleaner maximizes portability, and since it is light in weight but short in length, there may be restrictions on the cleaning area while sitting. Therefore, it is used to clean localized places such as on a desk or sofa, or in a car.
  • the stick vacuum cleaner can be used while standing, so you can clean without bending your back. Therefore, it is advantageous for cleaning while moving a large area. If a hand-held vacuum cleaner cleans a narrow space, the stick-type vacuum cleaner can clean a wider space than that, and can clean a high place that cannot be reached by hand. Recently, a stick cleaner is provided in a module type, and the cleaner type is actively changed and used for various objects.
  • the robot vacuum cleaner automatically cleans the area to be cleaned by sucking foreign substances such as dust from the floor while driving the area to be cleaned by itself.
