Vacuum Cleaner

Vacuum cleaners have been around since over a century now. They are considered to be indispensable units for housecleaning purposes. They are known for their convenience and efficiency. Running a vacuum cleaner over the surface to be cleaned will effectively remove the dirt and dust present in that particular area. Vacuum cleaners are known to remove any object from the surface provided it is light enough for the suction that it creates and can enter its inlet valve.

One reason why vacuum cleaners are preferred over traditional cleaning equipment such as brooms and mops is that they do not need the mechanical force that these devices need and because they are much more effective at the cleaning process itself. One more advantage is that vacuum cleaners can be used on horizontal, vertical as well as inclined and inverted surfaces and can clean even inaccessible nooks and crannies easily, something that traditional cleaning devices cannot do.

There are various kinds of vacuum cleaners used for a variety of purposes today. The hundred odd years since their first invention has allowed them to evolve and become highly convenient and purposeful objects today. There are vacuum cleaners that are designed to remove solid as well as liquid particles known as wet/dry vacuum cleaners, vacuum cleaners that can be used in an upright posture known as upright vacuum cleaners, canister vacuum cleaners, handheld vacuum cleaners, lint removers, bug cleaners and many more. Some of the more versatile vacuum cleaners comes outfitted with hoses of various dimensions. At the same time, there are vacuum cleaners of various shapes, sizes and bulk.

A typical vacuum cleaner will contain an inlet valve, a fan with electric motor and an exhaust valve. The fan is the most important component. It is designed with slanted blades so that when it moves, it can create a higher pressure below (where the inlet valve is present) and a lower pressure above (where the exhaust valve is present). Air has a tendency of moving from an area at higher pressure to an area at lower pressure. Thus, when the fan is put on, a current of air begins to move from the inlet valve to the exhaust valve. The electric motor connected to the fan energizes it for its motion.

The inlet valve is separately energized. It contains a horizontal cylinder with a spiral brush arrangement on it. When the cylinder rotates (it can rotate at high speeds), the entire brush comes in contact with its surface. As it moves, the brush sweeps out the dust and dirt particles from the surface. Once loosened, these particles move with the flow of air in the direction of the current.

A dust bag is attached somewhere between the inlet valve and the exhaust valve. It may be placed in between the inlet valve and the fan (as in canister vacuum cleaners) or it may be placed between the fan and the exhaust value (as in upright vacuum cleaners). The purpose of the bag is to collect the particles as they move with the air current. These bags also act as filtration devices. They are porous but with pores so tiny that the air can pass out of it but the dust and dirt particles remain trapped within.

Bags will accumulate these particles till they collect so much of it that it will reduce the efficiency of the cleaning process and will need to be emptied out. From here, the air current moves out of the exhaust valve. The current is continuous as long as the vacuum cleaner is in operation.

Some vacuum cleaners will need their bags to be replaced often while some of them will not use bag arrangements at all, but a compartment where the particles are collected. Even these will need to be emptied out, but they make replacement bags unnecessary due to which they have become more popular.

Vacuum cleaners are measured by two factors – the amperage, which is the power of the motor driving the fan, and the gallon capacity, which is a reference of how much air current it can take in at one time.

  1. Very good overview of vacuum cleaners! One aspect interesting to consumers is the difference between canister and upright vacuums.

    Canisters typically have better suction power and are easier to store, while the uprights may have bigger bags (or are bagless) and are easier to maneuver – at least the latest Miele and Hoover models.

  2. I second what the Wizard says. A very good article that provides some history as well as descriptions of many aspects of a vacuum cleaner rarely mentioned in most generic reviews. If I were to add anything it may be that while bagless vacuums do not require the purchasing and disposing of bags, they do have filters that need to be maintained or replaced and they rely on seals to prevent the dirt-container from leaking. It seems some consumers are big fans of bagless vacuums while others wouldn’t consider anything other than a bagged machine. It appears top be a matter of personal preference.

    I’m partial to the Rainbow myself. It’s great for people with allergies, because it traps the dust in the water and keeps it from escaping back into the air.

    On the topic of bags vs. bagless vacuums, I’d like to add that while “personal preference” comes into the equation, much of that bias can come from poor design and previous experiences. In 2000 my wife and i bought a Hoover wind tunnel–upright, bagless–because it was the highest rated vacuum by Consumer Reports. Bagless was a no-brainer to me because it saved money and was reduced waste.

    Every time I emptied that thing, I ended up breathing a cloud of stink and dirt. In 2005 we wanted a new vacuum, so of course our next vacuum had a bag. Since then I’ve seen designs that deposit the filth at the touch of a button from an otherwise closed canister. It’s something I’ll definitely be paying attention to when I pick my next one.

    I have to say, the more powerful the vacuum the better. I know the Miele canister is quiet and powerful. My sister bought one and absolutely loves it. She also has two casts and has been fighting fur balls for years. With her new vacuum, she is one happy person.

  6. Thanks for providing the history of the vacuum. I prefer the canisters because the suction I find to be better with those, and it does not leave such a dusty smell like the upright one does. Glass shatters, I can use the canister vacuum to clean it no problem where as the upright can be ruined by it easily. That has been my experience anyway. Not to mention I have not had the best experiences with upright vacuum cleaners as they are less durable than the canister types. But cleaning out the canister is a big pain, and whoever does the cleaning up must not have dust allergies.
