Robotic Vacuum Cleaners...

Posted by admin in Vacuum Cleaner on September 2, 2009 | No Comments

As technology gets better and better, life will get easier as well.  Not only are computer going at impressive speeds, but even household appliances such as vacuum cleaners are evolving.  If you’ve never heard of a robotic vacuum cleaner, you will soon.  These small robotic battery powered creatures will roam around your home, looking for dust and debris.  They are designed to do your vacuuming for you and make life easier than ever before.

The robot type vacuums were invented by Electrolux then introduced into the consumer market in 2001. After that came Roomba vacuums, as they perfected cordless vacuums and took things to the next playing field.  If your wondering how they can improve your life, just think about coming home after a hard day at work, sitting down to watch television, and letting the robot do all of the vacuuming for you.

The Roomba robotic vacuum cleaners use a 3 stage cleaning system that is designed to clean the edge of your walls, underneath your furniture, and  anywhere else it detects dirt.  These robots can actually detect the dirty areas on your carpet or floors and do extra cleaning in those specific areas to get the job done right.

These vacuums actually have a brain of sorts, so they can detect such things as stairs and stay clear of them.  By using infrared sensors to detect the stairs in your home, they can quickly and easily stay away from them.

After the room as been cleaned, the robotic vacuum cleaner will go back to the recharge station to charge its battery for the next time you need to use it.  Keep in mind that Roomba isn’t the only company that makes robotic vacuum cleaners, as  other models worth checking out include Karcher RC 3000, EVac, and Samsung.  The most popular
type however, is the Roomba Discovery SE.

When you look at things as a whole, you’ll quickly see that robotic vacuum cleaners are the way to go.  They can save you a lot of money in the long run, and a lot of time and effort as well.  When you get a robotic vacuum cleaner, you can rest  assured that your days of vacuuming are over.

When it comes to price, the price will vary depending on the model you select.  You can find Roomba models these days for under 100 dollars, which is perfect for those on a budget.  Now days, you don’t need to spend a fortune to get a robot vacuum cleaner for your home.

To get your robotic vacuum cleaner, you can check your local store or online.  You can find some impressive deals online, with hundreds of stores at your fingertips.  All you have to do is select the model you like best, buy it, then watch it do all of your vacuuming from here on out!

How Vacuum Cleaners Work...

Posted by admin in Vacuum Cleaner on August 27, 2009 | No Comments

Even though it may appear to be a very complicated machine, the conventional vacuum cleaner is actually made up of six essential components:  intake port, exhaust port, electric motor, fan, porous bag, and  a housing that stores all of the other components.

When you plug the vacuum cleaner into the outlet and turn it on, the following happens:
1.  First of all, the electric current will operate the motor, which is attached to the fan, which resembles an airplane propeller.
2.  As the blades begin to turn, they will force the air upwards, towards the exhaust port.
3.  When the air particles are driven forwards, the density of the particles will increase in front of the fan and therefore decrease behind it.

The pressure drop that occurs behind the fan is similar to the pressure drop when you take a drink through a straw.  The pressure level in the area that is behind the fan will drop below the pressure level that is outside of the vacuum cleaner.

This will create a suction inside of the vacuum cleaner.  The ambient air will push itself into the vacuum cleaner through the intake port because the air pressure that is inside of the vacuum cleaner is much lower than the pressure on the outside.

Picking the dirt up
The stream of air that the vacuum generates is just like a stream of water.  The air particles that move will rub against any loose dust or debris and if it is light enough, the friction will carry the material around the inside of the vacuum cleaner.

As the dirt continues on to the exhaust port, it will pass through the cleaner bag.  They tiny holes in the vacuum cleaner bag are large enough to let the air pass through, although too small for the dust particles to fit through.  Therefore, when the air current gets into the bag, the dirt and debris will be collected there.

You can stick the bag anywhere along the path between the intake tube and the exhaust port, just as long as the air current passes through.

Suction
The power of a vacuum cleaner’s suction will depend on several factors.  The suction can be stronger or weaker depending on:
1.  Fan power – In order to generate a strong suction, the motor needs to turn at a good speed.
2.  Air passageway – When a lot of debris builds up in the bag, the air will face a greater level of resistance on the way out.  Each particle of air will move slowly due to the increase in  drag.  This is the reason why a vacuum cleaner works much better once you’ve replaced the bag than when you have been using it for a while.
3.  Size of the intake port – With the speed of the vacuum fan being constant, the amount of air that passes through the vacuum cleaner per second is also constant.
