A Dyson vacuuming system that sold for nearly $1 million in April 2016 after a campaign to raise awareness of air quality concerns led to a $1.7 million buyback and was one of the largest sales of a cleaning product in history, according to data released by the manufacturer.
Dyson, which has made a series of air-quality campaigns since 2009, says it had been “outgrowing” its own inventory of vacuums and had purchased about 5 million vacuum cleaners at a cost of about $5.5 million.
The buyback is part of a larger $2.9 billion buyback program the company announced in November.
The company did not immediately respond to a request for comment.
Dyson, based in Northbrook, Illinois, had previously sold about 1.2 million vacuum cleaning products in 2016.
The purchase price for the 1.5-liter model was $1 in 2016, up from $1 per 1,000 vacuum cleaners bought in 2016 and $1 for each vacuum cleaner sold in 2015.
The price of the $1 vacuum cleaner was $2,500.
The total buyback was about $1 billion.
The campaign to get consumers to use the product became a rallying cry in 2016 for the U.S. Environmental Protection Agency.
Diversions in the vacuum industry helped fuel a campaign by environmental groups and consumer advocacy groups.
Dermot O’Leary/Bloomberg NewsDyson’s sales are on track to break the record for the biggest sale of a vacuum cleaner in history.
It is the company’s fourth straight year of selling more than $1 a pound in a month.
In 2015, Dyson had sold nearly $2 billion in vacuum cleaners, according the company.
It has been the subject of numerous public health and safety complaints, including the potential for harmful chemicals in some of the products.
