I have a friend who has spent a lot of money on a new vacuum cleaner. He wanted to get the quietest model available.
Many notoriously noisy appliances such as vacuums, washing machines, dryers and dishwashers are available in much quieter versions now. Of course, appliances that have the quieter technology are more expensive than the traditional noisy versions.
My friend was willing to pay more to have a new quiet vacuum cleaner so that he would be able to hear his television while doing housework.
