Dyson has introduced the first vacuum cleaner boasting no bag, no loss of suction - and a filter that never needs changing.
The company's Cinetic technology uses cyclones that are so efficient the filter never requires washing or replacing.
Cinetic, showcased at Berlin IFA tech show in the German capital, separates microscopic particles - meaning clogging dust is simply thrown away.
Engineers tested Cinetic with the amount of dust collected in a household in 10 years and found it never lost suction.
James Dyson said: "Getting rid of bags solved the frustration of my vacuum losing suction. But washing filters - or worse buying them - is still a nuisance.
He added: "... Everything gets thrust in the bin, and you can forget about fussy filters."
Why are you making commenting on The Herald only available to subscribers?
It should have been a safe space for informed debate, somewhere for readers to discuss issues around the biggest stories of the day, but all too often the below the line comments on most websites have become bogged down by off-topic discussions and abuse.
heraldscotland.com is tackling this problem by allowing only subscribers to comment.
We are doing this to improve the experience for our loyal readers and we believe it will reduce the ability of trolls and troublemakers, who occasionally find their way onto our site, to abuse our journalists and readers. We also hope it will help the comments section fulfil its promise as a part of Scotland's conversation with itself.
We are lucky at The Herald. We are read by an informed, educated readership who can add their knowledge and insights to our stories.
That is invaluable.
We are making the subscriber-only change to support our valued readers, who tell us they don't want the site cluttered up with irrelevant comments, untruths and abuse.
In the past, the journalist’s job was to collect and distribute information to the audience. Technology means that readers can shape a discussion. We look forward to hearing from you on heraldscotland.com
