Silent vacuum cleaners during operating time actually make sounds, just the level of their noise is much lower, than at the majority of traditional models and, as a rule, 70 dB do not exceed. The cost of such products is rather high, besides increase in the price is connected with convenience of models, but not with quality of cleaning.
Instruction
1. Pay attention to the net power of the silent vacuum cleaner. It is the most important point: often producers intentionally underestimate this characteristic, seeking to reduce noise level to minimum, and as a result the device becomes useless as cannot qualitatively remove dust and garbage. Do not mix net power from electric. Optimal variant – 240-480 W.
2. Give preference to models with noise level 65-70 dB or less. "Louder" devices can be called noise-free only in the advertizing purposes, however actually they cannot brag of such advantage. Remember that some sellers and producers specify noise level in the economic, i.e. most silent mode. It is useful to specify this moment, having checked the instruction.
3. Try to choose the device with power control. It is very convenient: you will be able to change force of suction and loudness of noise and to do operation of the vacuum cleaner almost silent if necessary. It is important that the power adjuster was located in the convenient location. For example, good option – placement of this part on the handle.
4. Choose the vacuum cleaner taking into account its weight and the sizes. To reduce noise level, producers use different receptions among which and use of the special materials "extinguishing" vibrations and sounds. The more such materials it is used, the device is heavier and larger. It is important that it was convenient to you to store the vacuum cleaner and to use it therefore consider the area of the apartment and own physical capacities.
5. Look for popular models to which it is easy to buy consumables. Very seldom silent vacuum cleaners belong to the category washing or cyclonic – as a rule, such devices are complemented with refuse sacks as this option allows to achieve the lowest noise level. However, unfortunately, to some rare models of such vacuum cleaners it is difficult to buy suitable bags, and it becomes serious problem for users.
