(but lack of data)

TWh

Vacuum cleaners - Categories:

. No technical Categories

. Canister . Upright . Motorized Brushes . Bags/cyclone etc. . All performing same function . difficult to define . Could limit e.g. inovation if ‘new type’ was excluded from labelling

l

Vacuum cleaners - Categories:

. Functional Categories

. All Purpose . Carpet only . Hard Floor only . Some VCs designed only for one one surface . No need to penalize, . Warn customer that only designed for Hard Floor or Carpet

l

Vacuum cleaners - Categories:

. Domestic Low voltage Directive . Commercial Machinery Directive

Same

. Ecodesign requirements . Information requirements

(possibly no label for commercial VCs)

. Finland need more clarification –

definition of commercial/domestic

l

Vacuum cleaners - Impacts:

. Energy in use 20-30 TWh

. Noise . Cleaning Increased Hygiene . Dust Re-emission Reduced pm (0.4-4 µ)

l

VCs – Policy : Noise

. Label

» dBa figure

. Ecodesign

» No Limit

. ECMA – Commercial VCs covered by Machinery

Directive already defines noise with limits – should follow

. ANEC should include noise limit (76 dBa)

l VCs –Dust re-emission

. Technical particle size included

» E.g. 0.4 - 4 micron

l VCs –: Dust re-emission

. Technical impact on indoor environment

» Indoor particulate much higher than outdoor levels » Significant health impact » Not clear that ‘very good’ filtration (e.g. 99.5%)

significant improvement over ‘good’ filtration (e.g. 98%)

» Very important to some consumers (e.g. households

with asthma suffers)

l

VCs –: Dust re-emission

» 0.3 µ to 20 µ » 1% after 1 year, 0.4% after 3 years

l VCs –Cleaning performance

. Dirt removal after 2 Double Strokes

» More realistic than 5 double strokes » Repeatability and Reprocability a little worse than after

5 double strokes

l VCs –: Cleaning performance Comments

. Ecodesign

»

NL suggest limits of 65% carpets and 95% hard floor (5 double strokes) would meet (CECED) concerns about very low performance VCs receiving a label or better

»

Ro suggests limits

»

ECOS limit after 2 Double Strokes

»

ANEC limits of 55% carpets and 85% hard floor (2 double strokes)

l VCs –: Energy Consumption

. Real Life Behaviour

Information available suggests

» 2 double strokes (regardless of level of cleaning)

l VCs –: Energy Consumption

. Real Life v. EN standard

» Real life Cleaning times implies about 2 double strokes

in test

» Floor must be covered at least once » Test floors probably ‘dirtier’ than real life

(so fewer ‘double strokes’ needed to achieve set cleanliness)

l VCs –: Energy Consumption

. Real Life v. prEN standard

» Cleaning time implies about 2 double strokes in test » Floor must be covered at least once » Test floors probably ‘dirtier’ than real life

(so fewer ‘double strokes’ needed to achieve set cleanliness)

l VCs – : Energy Consumption

. Study

» LLCC for (standard size) vacuum cleaner

750W – about 28 kWh per year

» Extra costs low (and saving from smaller motor)

l VCs – : Energy Consumption

. Annual Energy Consumption

» Power input x Annual Cleaning time

l VCs – : Energy Consumption

. Annual Energy Consumption

Power input x Annual Cleaning time

. ANEC – suggest label etc on rated input

power (A 800W G 1200 W) (as in study)

l VCs – : Energy Consumption

. Annual Cleaning time

»50 Cleans x 87M² x 2 double strokes x F x P

+ 5h idle time

(divided between 40 M² carpet & 47 M² hard floor) (time to clean 87M² from head width and velocity of 0,5M/s)

l VCs –: Correction Factor ‘F’

.

Penalizes Vacuum Cleaners with ‘bad’ cleaning performance where after 2 double strokes users may still see visible dirt and so may continue to clean.

l VCs –: Correction Factor ‘F’

»For VCs with at least average Dust Pick up:

»For VCs with below average Dust Pick up:

VCs –: Correction Factor ‘F’ Comment

.

Penalizes Vacuum Cleaners with ‘bad’ cleaning performance where after 2 double strokes users may still see visible dirt and so may continue to clean.

. CECED suggests factor insufficient so

VCs with very low power and very low performance could still receive A energy rating (or better) – but with G performance rating.

l VCs –: Correction Factor ‘P’

.

Penalizes Vacuum Cleaners which require ‘high’ push force (over 25N), where users may push vacuum cleaner more slowly.

l VCs –: Correction Factor ‘P’

.

Penalizes Vacuum Cleaners which require ‘high’ push force (over 25N), where users may push vacuum cleaner more slowly.

l VCs –: Correction Factor ‘P’

.

»For VCs with push force under 25N:

1

»For VCs with push force over 25N:

Push force 25

l

VCs –: Correction Factor ‘P’ Comment

.

Penalizes Vacuum Cleaners which require ‘high’ push force (over 25N), where users may push vacuum cleaner more slowly.

. NL suggests different formula and

limit of 50N

l

VCs –: Energy Consumption Comments CECED

. Annual Cleaning time

»50 Cleans x 87M² x N double strokes + 5h idle time »Where » N is the extrapolated number of double strokes to achieve

reference cleaning performance.

»E.G. if cleaning performance on carpet after

• 1ds is 60, and after 2ds is 70 - then
• N = 1.5

(No other correction factors)
