Daniel Hess invented a machine with a bellows for suction and arotating brush in 1860, but it was largely impractical. Ahand-pumped vacuum cleaner invented by Ives McGaffey appeared andwas patented in 1869. In 1901, Cecil Booth, a British engineer,invented a large contraption built on a wagon that w…as set upoutside buildings and had hoses running through windows to servicemultiple rooms. Booth had seen a machine originated by an American,and this was a springboard to his device. The Chapman and Skinnermachine from San Francisco (1905) worked, but at nearly 100 pounds,did not sell. James M. Spangler's idea was purchased by WilliamHenry Hoover, who built and marketed a unit with a bag attached toa long handle beginning in 1907. As is so often the case with inventions, a "standard" devicedoesn't appear out of the blue. Rather, a good working design isdeveloped from different ideas that appeared over time before abreakthrough of sorts incorporates those older designs and a bit ofnew thinking. (MORE)

To use a vacuum cleaner, you plug the cord into an outlet, click the on switch, and glide the bottom of the vacuum on the floor! It will suck up any little pieces of stuff on the ground, but make sure that you clean up any big things before vacuuming so it does not ruin your vacuum!
Bagless When you turn on the vacuum cleaner, the suction from the motor (either top or bottom) sucks in dirt and dust, bringing it into the cyclonic dust bin, and preventing it from getting into the motor by using a dust filter. When full, you must dispose of the waste in the cyclonic dust bin…, either dumping it into the disposal or using a flip bottom. Bagged When you turn on the vacuum cleaner, the suction from the motor (either pulling it in by a fan driving a belt or a fan behind or below the bag) sucks in dirt and dust, bringing it into the bag (usually filtered). When full, you must dispose of the bag and replace it with an empty one. (MORE)

A vacuum cleaner is used to suck up a mess or dirt in a carpet oron tile or wood floors, and all the gross junk goes into a bag orcontainer you throw away or dump in trashcan.

Overwhelmingly, no. There are only two steam cleaners available on the market with a built in vacuum. Most people don't buy them to use as a vacuum cleaner though, they are bought because the vacuum gives the steam cleaner the ability to clean carpets on top of their already well known ability to cl…ean hard surfaces. There are some steam cleaners that can be used for carpets and rugs. In fact, they tend to clean the carpet better than most vacuums. They do a much better job at deep cleaning, removing carpet stains, eliminating allergens. Some provide the ability to achieve all of this without harmful chemicals. (MORE)
a vacuum cleaner uses air to create suction. in a vacuum there is no air. Therefore, the aswer is NO.
First answer: 5 pounds Second answer: The suction is the maximum pressure difference that the pump can create. For example, a typical domestic model has a suction of about negative 20 kPa. This means that it can lower the pressure inside the hose from normal atmospheric pressure (about 100 kPa) b…y 20 kPa. The higher the suction rating, the more powerful the cleaner. One inch of water is equivalent to about 249 Pa; hence, the typical suction is 80 inches (2,000 mm) of water. This translates to 2.89 psi. (MORE)
The total cost for a vacuum cleaner when the sales tax was included was 362.96 the retail price of the vacuum cleaner was 349.00 What was the rate of sale tax as a percent?

No. First of all it wouldn't stay on the ground. and whywould you need to vacuum? A vacuum cleaner depends on a difference in air pressure tooperate. With no air pressure in space, there could be nodifference in air pressure and thus no operation. Inside a manned spacecraft, which is usually pres…surized a vacuumcleaner will obviously work just fine; especially for collectingand disposing of water globules. Also the standard NASA spacetoilet uses a modification of a vacuum cleaner for urinecollection. (MORE)
The machine gets its name from the fact that the fan in the unitmoves air and creates a low pressure pathway (a vacuum, though apartial one) that is open at the nozzle (or hose, when usingaccessories). Air rushes in at the opening of the pathway, and thatmoving air picks up debris. The air and dirt …is then carried to afilter or bag, and the air get out to be returned to the room.Debris is left in the dirt tank or in the bag for disposal. (MORE)
Air pressure out of the vacuum's exhaust automatically creates a negative pressure (a vacuum) at the machines front end - that picks up the dirt.
Advantages: *Cleans the floor *Sucks of dust Disadvantages: *Can take up space *Can be noisy *Boring to push around *Not very mobile
Although it is called a vacuum cleaner, it does not actually create a vacuum. Inside the cleaner there is an electric motor which drives a fan blade. This fan blows air out of the vacuum cleaner and this causes air to be drawn in to the cleaner at the other end. Thus the cleaner works by creating …an air flow, not a vacuum. (MORE)
About 100 something if its not that new and about 250 ish if it like just came out last year. But if its new and very useful it would be about 350 or maybe 400. That is worth it!
If the vacuum cleaner is powered by electricity this is used to turn the electric motor which is needed to create the suction or vacuum. That motor either has permanent magnets inside it, or the current passes through many "turns" of wire to create magnets when you switch the cleaner on. Early exper…iment in electricity showed that if a wire is moved in a magnetic field some current is created. Similarly, if a magnet is moved near to a wire the same result occurs. So, yes the cleaner does need a magnet. (MORE)
Although regular dry vacuuming removes the surface layer of everyday dust, embedded dirt and grime still exist in your carpet, making fibres look flat and lifeless.
