Power (suction power) and energy consumption
The power is expressed in watts (W). The higher the engine's power, the better the performance. It is considered a good power from 1,100 watts but there are models of up to 3,000 watts. However, it is important that the vacuum cleaner has a power regulator since it is not always recommended to use the maximum power or suction flow, which consumes more, but adapt it to each surface. The suction capacity will depend on the power and also the design of each model and its features. The suction power is measured in suction watts or in kilopascals (kPpa), which is a unit of pressure. The higher the suction power, the more cleaning capacity. To vacuum large surfaces, we recommend opting for electric cord models rather than battery models, which have lower power and a much reduced operating autonomy. The power required will also depend on the frequency of the aspirate: the higher it is, the less dirt you will have to clean, the less power you will need and the lower the energy consumption on your electricity bill. The key to finding the best vacuum cleaner is the information of its energy label, which since 2017 reports its energy efficiency (the most efficient is the A +++ and the least the D) and its energy consumption in kilowatt hours over a year , with normal daily use. Here is an example of the current energy label of a Bosch vacuum cleaner :The volume or capacity of the bag or deposit (expressed in ml)
The more volume, more comfortable to use because it avoids having to change the bag or empty the tank. Some models are equipped with light indicators to fill the tank. The sled vacuum cleaners and the vertical ones are the ones with the highest capacity. The capacity of paper bags ranges from one and a half liters to more than six liters. Disposable bag models are preferable because less dust is spread when exchanging the bag than when emptying the tank or container, although the suction power is reduced as the dust bag becomes full since air circulation becomes difficult. There are models without a bag that incorporate powder compression technology, which forms compact blocks of dust that are more hygienic and easy to empty, thus avoiding dispersing the dust particles collected by the house. Almost all vacuum cleaners incorporate suitable filters, both to protect the motor and so that the dust aspirated does not return to the environment. Better if they are washable. The HEPA filters (English High Efficiency Particulate Air ) have excellent properties. But other filter models are equally effective. HEPA filters have small glass fibers that form a very dense sieve that captures tiny particles. Once the contaminant particles have passed through the filter they can not return to the air again due to their highly absorbent pores. There are different levels of Hepa filter quality on a scale of 10 to 14. There are also washable antibacterial filters, such as CORE filters . Activated carbon filters eliminate odors and are practical if there are pets at home. The "ecological" models have a water filter that cleans all kinds of dry, liquid or damp dirt.
The length of the cable and the arm or vacuum tube
The longer the cable, the greater the radius of action of the vacuum cleaner, that is, the area that you can clean without having to look for another plug. The average acceptable length is around 7 to 8 meters . For its part, the long tube facilitates the cleaning of high places and it is convenient that additional extension tubes are incorporated. Almost all models include retractable cable or automatic cable winding. Better with rotating elbow to suck in different directions without having to drag the motor, and better the flexible hose aspirators and ergonomic handle.Noise that emits in operation
Do not just look at the volume reached by the vacuum cleaner in operation (measured in decibels, dB) but also in the sound frequency (measured in hertz, hz). It is expressed as follows in the energy label: "Noise level: Noise (dBA) / Frequency (Hz)". In online stores you can do a search " silent vacuum cleaner " and find many models designed for people (like the one who writes), sensitive to the noise of vacuum cleaners.Security system
It is convenient that the vacuum cleaner has safety devices such as: stopping the engine in the absence of a bag or when it is misplaced, indicators that indicate the filling of the bag, to change it or that the filter is saturated, or thermal safety systems protections on the parts exposed to blows against corners or furniture protections on the wheels to avoid scratching the floors, etc.Other features that facilitate the use
Make it easy to transport : look at the weight, on the handle (which is ergonomic), that the wheels are multidirectional, that it can be stored in a small space, etc. That is easy to handle : that the controls can be operated with the foot, that it brings different extension tubes and brushes, that it has dirt sensors that indicate when to go over a specific area of the floor or the carpet (although this feature makes the product more expensive), Bring bumpers to avoid damaging furniture, etc.See More Topic:
