The European Union is looking at introducing legislation that would see the suction power of vacuum cleaners capped at 900 watts.
Although some of the current best-selling models on the market contain motors which rely on up to 2,000 watts of power, the EU wants to see them scrapped in order to reduce the average household's energy consumption.
According to a report by the Scotsman newspaper, draft legislation is due to be published on the matter next month.
The Association of Manufacturers of Domestic Appliances, the trade association for the domestic appliance industry in the UK, told the newspaper that manufacturers were concerned.
A spokesman said: "If you are affecting the amount of energy you have flowing through a product, then of course it is a concern about how that will impact on cleaning performance."
The EU's argument is that more power does not necessarily mean better cleaning. It's looking to manufacturers to alter their designs to help the environment without having to offer consumers inferior products.
