Do more with less.
The EU energy label is a reliable aid when buying a new home appliance. Since September 2014 vacuum cleaners also bear the EU energy label. At a glance, the label shows the energy efficiency class (A-G), the cleaning performance class on carpet and hard floors, and the noise and dust emission classes, making it easier to choose the model best suited to your personal needs. Since the introduction of the new energy label, new vacuum cleaners may not exceed 1600 watts power, and starting 1 September 2017 they may not exceed 900 watts. That saves energy and helps the environment.
But it means that manufacturers face the challenge of getting the same performance out of less power.
Transparency and helpful orientation - the energy label.
The new energy label gives all the important information at a glance to help you choose the right vacuum cleaner.
1. Energy efficiency class
Lower power consumption is the main criterion for a favourable energy efficiency rating. Cleaning performance does not play a large role in it.
2. Average annual energy consumption
Calculated for an average home with 87 square metres living area and 50 vacuumings per year.
3. More detailed information
The two cleaning performance classes on the lower part of the label are especially important for choosing a vacuum. Comfort-related ratings like dust emissions and noise level are also in this area.
How important is low energy consumption to you?
The top part of the label contains the energy efficiency class (A to G) and the average energy consumption. The two cleaning performance classes on the lower part of the label are especially important for choosing a vacuum, because energy efficiency class "A" does not necessarily mean that the vacuum will do a good job of cleaning.
1. Dust re-emission class
Shows how clean the exhaust air is, measure by the number of particles in the air coming out of the vacuum. It is affected by the type and quality of exhaust filter, and the sealing of the appliance.
2. Sound power level
Indicates the noise level of a vacuum cleaner in dB(A). Just a few decibels make the difference between a vacuum that is very loud and one that is nice and quiet.
3. Carpet cleaning performance class
Measured by the percentage of dust picked up from a standardized test carpet. Dust pick-up describes the amount of dust picked up from the carpet with a new bag in the vacuum cleaner. The best of today's vacuums reach class C. Higher dust pick-up means reliable deep-cleaning of the subsurface.
4. Hard floor cleaning performance class
Measured in percentage of dust picked up. It describes the dust pick-up out of a dust-filled crevice in a wooden test panel.
