The EU Standards ratings label also provides a wealth of information, including an overall efficiency and energy rating. This can range from A to G, and we recommend looking for a vacuum that falls within the A to C range. You also get information on energy usage (measured in kWh per year) and noise level (measured in decibels).
Also included is Pick Up Ratings for both Carpets and Hard Floors – which usually raises the question of ‘what on earth does carpet pick up rating C mean?’ This is a measurement of how effectively the vacuum cleaner will remove dirt and debris from the different flooring types, as determined by laboratory testing. Finally, you also get a Filtration rating (again between A to G), which indicates how well the vacuum retains the fine dust it picks up without blowing it out again.
