In a vacuum cleaner, you need one that is sturdy and simple but it has to be the right price. Most heavy duty vacuum cleaners out in the market can last up to 15 years. When you find one that is dependable and the instructions on how to use is a breeze, you can say your money is put in a good investment. Dirt Devil’s famous M083414 stick vacuum cleaner received numerous good reviews online. This stick vacuum is lightweight, battery-charged, bagless, and popular for use in cleaning both bare floors and carpets. It is also designed to pick up crumbs under the table but not suitable to clean the edge along the walls though. The M083414 has an agitator and it releases trapped dirt in small, hard to reach areas. With its 14.4-volt battery, it holds power long enough to accomplish small size pickups. But to clean the entire house, you may need to charge the battery halfway.

If you want to remove spills on tile or wooden floors, you may turn off the revolving brush. This 4 pound Eureka Lightweight Easy Clean Upright Vacuum Cleaner easily picks up everyday messes, like dog hair and dust bunnies be it on floors or delicate carpets. This bagless cleaning machine empties your house from dust starting from top all the way to the bottom easily and quickly. It perfectly cleans your furniture, stairs, sweeping up crumbs under the table or around your baby’s high chair, including small debris from rugs and carpets. kenmore true hepa vacuum cleanerIf your problem is dog hair, dog food, crumbs, even sands that get tracked into the house, its suction is just excellent to clean them all up.small cyclone vacuum cleaner With its long cord, you can pretty clean a single room without re-plugging. best vacuum cleaner in india 2011

It can be converted easily into a dust buster when you detach the handle and push down inside and pop the flat part off the bottom. To reach under the couch and tables, the vacuum bends each of the way down to the floor. It’s only about five inches tall when laid on the ground so it can be stored under most furniture. Carpet Pro CPU-1 Heavy Duty has a patent clean air bypass motor system which makes this an effective cleaning machine. Much larger than the newer robotic cleaning machines. As long as you keep the filter clean by washing, your motor should last up to 15 years! In addition, the motor, handle, bottom plate and the roller brush are all made up of metal – heavy and solid, yet roll smoothly! The brushes are made of Teflon and slides out of the brush roll so you can replace the brushes and there is no need for you to go to the hassles of replacing the entire roller brushes! Another advantage of this carpet cleaning machine is its versatility in picking up every unsupportable piece of dirt and lots.

There is a minor downside though – no on board storage of tool. Listing down all the benefits this product offers like affordability, durability, superb quality, and prompt delivery, this vacuum cleaner is worth your money. Understanding Vacuum Motor Terminology Vacuum Motor Design & Operation How to replace filter bags in a Ducted Vacuum VACUUM MOTOR DESIGN AND OPERATION The most common ducted vacuum motor consists of a rotating armature and a stationary field. The armature is made of a laminated iron core which is wound with copper enamel-insulated wire. The windings are attached to a copper commutator near one end of the armature. The commutator has individual bars of copper which are positioned in the shape of a drum. The motor brushes are carbon rods which are held against the commutator in order to carry the electrical current to the windings on the armature. The field consists of a laminated iron frame on which one or two coils of copper wire are wound.

It is shaped so that it wraps around the core of the armature on two opposite sides. Since the same current passes through the field coils and the armature coils, it is termed a series motor. As current passes through the coils in the field and armature, magnetic fields are created by each of them. It is the attracting or repelling of these fields which cause the armature to rotate within the field. The fans (impellers) are an integral part of the vacuum motor as the fan housings and the motor are assembled as a complete unit by the manufacturer. Being a series type motor it is capable of creating high levels of torque for its size. As current increases through the motor, the magnetic fields created by both the armature and field increase proportionally. Therefore, with lighter loads the torque is proportional to the square of the amount of current flowing through the motor. If the current is doubled, the torque is increased by four times. Under heavy loads the field’s magnetic strength reaches a point of saturation whereby it can no longer increase.

Then the torque increases only in proportion with the change in the current flow. Vacuum motors are designed to operate at very high speeds under moderate to heavy loads. The load to a vacuum motor is an interesting and unusual phenomenon. One or more fans (impellers) are attached to the motor shaft and are rotated at a very high speed. The air entering the fans is forced to spin with the fans as it passes through it. The load to the vacuum motor is the force needed to overcome the inertia of the air as it enters the fans. When you reduce the air flow to the motor by increasing air flow resistance, the load on the motor is actually reduced so the motor speed increases and current through the motor decreases. The effect of this is to increase the suction created by the motor which helps to counteract the effect of the resistance to the air flow. If you restrict the air flow completely, it will create its maximum possible suction. This is what happens when a vacuum gauge is used to measure sealed vacuum.

In reality, it is greater than the suction which is produced in the normal operating range of the motor. A substantial amount of energy is dissipated in the form of heat. This is primarily the result of resistance in the copper windings on the armature and field as current flows through them. BYPASS & FLO THRU MOTORS Most ducted vacuum cleaners currently use what is known as a bypass motor. In this type of motor, a separate fan circulates clean air around the armature and field to cool them. This design is also used on almost all commercial vacuum cleaners and steam cleaners since it is unsafe to pass damp or wet air over the electrical components. In the event that a ducted vacuum system with a bypass motor is operated without filtration, the dirt and dust will be exhausted without any damage to the motor itself. Almost all portable and some ducted vacuum cleaners use a flow-thru motor. The air which has already passed through the fans (impellers) is directed around the armature and field to cool them after it exits the fans.
