This is a list of vacuum cleaners and robot vacuum cleaner manufacturers. A vacuum cleaner is a device that uses an air pump to create a partial vacuum to suck up dust and dirt, usually from floors, and optionally from other surfaces as well. The dirt is gathered by either a dustbag or a rigid cartridge, which may be emptied and reused.
Upon seeing the dust and dirt collected on the underside of the handkerchief, he realized the idea could work. Booth created a large device, [11] driven by an internal combustion engine. Nicknamed the "Puffing Billy", [12] Booth's first petrol-powered, horse-drawn vacuum cleaner relied upon air drawn by a piston pump through a cloth filter. It ...
Instead, the dust is separated in a detachable cylindrical collection vessel or bin. Air and dust are sucked at high speed into the collection vessel at a direction tangential to the vessel wall, creating a fast-spinning vortex. The dust particles and other debris move to the outside of the vessel by centrifugal force, where they fall due to ...
"This movement was a key design feature as it has a double connected bellows, meaning that movement in either direction created a vacuum." The second person could use the attached hose then to clean the house. The dust was collected in a cotton bag within the machine. An example of this can be seen at the Walthamstow Pumphouse Museum
Air and dust are sucked at high speed into the collection vessel at a direction tangential to the vessel wall, creating a fast-spinning vortex. Roughly speaking, the dust particles and other debris spiral outward to the wall of the vessel by centrifugal force, where they fall due to gravity into the bottom of the
Spillbuster 2000 from 1998. The Black & Decker DustBuster (now stylized as DUSTBUSTER) is a cordless vacuum cleaner that was introduced in January 1979.. Mark Proett and Carroll Gantz are listed as the inventors on the utility and design patents, respectively, assigned to Black & Decker for a cordless vacuum cleaner.
Most general pumps can increase as well as decrease the pressure of a gas; however, this category contains pumps that are usually exclusively used to decrease pressure. Wikimedia Commons has media related to Vacuum pumps .
