# Commission Regulation (EU) No 666/2013 of 8 July 2013 implementing Directive 2009/125/EC of the European Parliament and of the Council with regard to ecodesign requirements for vacuum cleaners (Text with EEA relevance), Division 3: Annual energy consumption

Extent: E+W+S+N.I.

The annual energy consumption AE is calculated, in kWh/year and rounded to one decimal place, as follows:
for carpet vacuum cleaners:
AE c = 4 × 87 × 50 × 0,001 × ASE c × 1 − 0,20 dpu c − 0,20
for hard floor vacuum cleaners:
AE hf = 4 × 87 × 50 × 0,001 × ASE hf × 1 − 0,20 dpu hf − 0,20
for general-purpose vacuum cleaners:
AE gp = 0,5 × AE c + 0,5 × AE hf
where:
ASEc is the average specific energy consumption in Wh/m2 during carpet test, calculated as provided below
ASEhf is the average specific energy consumption in Wh/m2 during hard floor test, calculated as provided below
dpuc is the dust pick-up on carpet, determined in accordance with point 4 of this Annex
dpuhf is the dust pick-up on hard floor, determined in accordance with point 4 of this Annex
50 is the standard number of one-hour cleaning tasks per year
87 is the standard dwelling surface to be cleaned in m2
4 is the standard number of times that a vacuum cleaner passes over each point on the floor (two double strokes)
0,001 is the conversion factor from Wh to kWh
1 is the standard dust pick-up
0,20 is the standard difference between dust pick-up after five and after two double strokes.
