Today, vacuum is one of the most popular household appliances, and is present in almost any apartment. High demand stimulates companies to constantly expand the functionality and range of their models. But the variety of the model range sometimes complicates the choice of the optimum vacuum. Primarily, it depends on the price, characteristics and functionality of the model.
Main functions and characteristics of modern vacuums.
Suction power adjustment.
Modern models have the mechanical or automatic suction power adjustment.
Mechanical adjustment is carried out with the help of controls on the handle or on the device housing.
Digital adjustment is carried out with the help of remote control with digital display. Such models are significantly expensive. This function is implemented, for example, in Miele vacuums.
Power adjustment is designed to select the optimal level that is different for coating types. This function is convenient during sequential cleaning the carpet, linoleum and parquet, or for cleaning curtains. Optimal suction power is maximum for a carpet with a long pile and is minimal for curtains.
This function is also useful for models with battery, providing efficient use its charge.
Maximum power is well suited for quick cleaning. Lowered power is convenient for cleaning with minimal noise.
This function is intended for filter cleaning without disassembly of vacuum.
Cord length adjustment.
This function adjusts the power cable length and can work in fast or slow mode. It’s activated when the distance between the vacuum and the mains socket is reduced, eliminating the cable excess on the floor.
In some models, this function is automatically activated in the case of disconnection from the mains.
Heating dust is accompanied by an unpleasant odor. Ambia filter is intended to its eliminate. It uses special plate with a few drops of flavoring.
Carbon filter almost completely eliminates all unpleasant odors, but requires periodic replacement.
Flavorings in the form of granules can use in almost all modern vacuums with a dust bag.
Some models have active control module for automatic adjustment of the air aromatization level.
This function provides the high speed of the airflow at the vacuum outlet that is often very convenient. It can use, for example, for cleaning the air filter of the car, for coloring or for working in the garden or in the yard. Blowing mode is very convenient for cleaning territory from dust and leaves. Unfortunately, vacuums rarely have this function. It’s mainly present in wet / dry models.
Additional functions of models with water filtration.
These models often provide the steaming, fluid collection and electronic adjustment of water level and steam supply.
The maneuverability highly depends on the vacuum weight and shape of its wheels. The wheels are usually placed on sides of vacuum. Four wheels provide good maneuverability and steadiness. The rubberized wheels reliably protect the parquet and laminate against damages. They are better then plastic wheels. Some companies use the additional engineering solutions. For example, Dyson Company has developed the special Ball technology. Wheels with the ball shape provide turning on the spot and excellent maneuverability between the furniture.
However, the company continues to improve this technology. Its advantages are perfectly illustrated on the video at the end.
It depends on cable length and telescopic extension rod.
Cleaning area is usually 16 ft. Some models provide 23 ft or more. This value does not very important for the small rooms but extended cleaning area is very convenient in large rooms or in the courtyard.
Compartment for accessories.
Many models have a compartment for storing attachments in the vacuum body.
Also, it can be on handle or on pipe. However, this compartment increases the device dimensions.
Turbo brush is one of the major accessories of modern vacuums. It effectively removes the very small particles of garbage and pet hair. Turbo brushes use mechanical or electrical drive. Modern models are often complex device, that provides a significant improvement of cleaning quality.
Protection from the germs, fungi and bacteria.
Nano-silver coating on the HEPA filters is designed to protect against germs, fungi and bacteria.
Special antibacterial attachment with UV lamp is another way to deal with germs. They are usually sold separately. Sometimes it’s equipped with a vibrating mechanism. UV lamp kills harmful bacteria and microorganisms. The vibrating platform is designed for knocking out them from the dense fluffy coating. Their simultaneous operation provides the efficient cleaning from mites and other harmful microorganisms.
Protection from allergens.
Special design of turbo brush increases efficiency of cleaning the carpets from pet hair. For example, some model use fastening the bristles on a rotating shaft in a spiral.
It’s intended for convenient cleaning the surfaces of the shelves, cabinets or air conditioners.
The motor thermal protection function.
This function disables vacuum at a critical motor temperature. It protects the motor from overheating during intensive use and is present in almost all modern models.
Lock of false start.
This function is activated at absence of the dust container and protects from accidental ingress of dust and dirt in the device nodes. This situation occurs when a user forgets to set the dust bag.
It protects the motor against overload during a launch.
Automatic shutdown of the motor when filling the dust bag.
The protection relay turns off the motor.
The elastic rubber bumper protects the furniture from scratches and damage. Some models have the ability to replace the bumper.
The noise level is proportional to the engine power. Companies are constantly trying to reduce it. Developers use special sound insulating materials and optimization of air flows. Using amortization suspension for motor also reduces noise. These technical solutions provide good results. For example, models Stealth from Samsung or Ultra Silencer from Electrolux have noise level of 71-73 dB. This is a very good value for a powerful vacuum. The latest models of Bosch also are positioned as noiseless.
