Buying a vacuum cleaner can be an expensive investment. So it is important to know the criteria to remember about a vacuum cleaner without bag. In addition, as you use it, you will have to follow some tips for your bagless vacuum cleaner , such as optimizing suction or treating unpleasant odors.
The air flow rate
The air flow rate is the amount of air sucked in by the appliance per second. This indicator, expressed in liters per second (L / s) hardwood floor vacuum or cubic decimeter per second (dcm 3 / s). It tells you about the suction capacity of the air with dust to the tank.
The greater the airflow of the vacuum cleaner, the more efficient the appliance is and thus limits the number of passages to clean a surface. The average airflow for a vacuum cleaner with bag is 38 dcm 3 / s and 30 dcm 3 / s for a bagless .
It is expressed most often in Pascal kilos (kPa). It is the measure of the force exerted to lift and aspirate dust from the soil to the tank.
The higher the vacuum, the more your vacuum cleaner will be able to lift and aspirate large particles. Currently, the average vacuum value of vacuum cleaners with bag is about 30 to 40 kPa. As for vacuum cleaners without bags, the vacuum is about 25 to 30 kPa.
The useful power
This is the result of a combination of the two indicators mentioned above, the air flow and the vacuum. The balance between these two elements guarantees the efficiency of the device. In most cases, this information is not available in stores. So do not hesitate to contact the manufacturer to get them.
It is only an accessory of the vacuum cleaner, however it is the most important accessories because it is the brush that will determine the effectiveness of your vacuum cleaner on hard or soft surface. It is therefore important to learn about the brush to see if the vacuum cleaner is more suited to hard,bona hardwood floor mop soft floors or if it is made for both types.
The range of action
It is the addition of the length of the electrical cable, the hose and the device itself. And the greater the range of action, the less you will have to unplug the vacuum cleaner in search of the nearest free intake.
Manufacturers are making more and more efforts to ensure that the vacuum cleaner can be drawn with as little stress as possible. Indeed, the heavier it will be, the more painful it will be. Especially since you will sometimes be led to lift it.
The sound level
A vacuum cleaner in operation emits more or less noise. The latter is expressed in decibels (dB). This criterion is not necessarily negligible especially since it is recommended to choose a vacuum cleaner whose noise nuisance is as low as possible.
In addition, it should be noted that the noise doubles every 3 dB. In other words, a vacuum cleaner at 78 dB makes twice as much noise as at 75 dB and 4 times more than one at 72 dB. Between the quietest (around 65 dB) and those near an aircraft reactor (more than 80 dB), it therefore has nearly 40 times more noise. Vacuum cleaners without bag are more noisy, unlike models with bag. The bag acts as a sound insulator. swiffer wet jet batteries
