Vorwerk, which makes Thermomix, has drawn criticism for limiting the smart functions offered by its robot vacuum cleaners. The company reportedly broke promises to customers and ended cloud support earlier than planned. That change left some owners without features they had been led to expect from connected appliances. A project called Vacoola aims to reverse the loss by providing a way to restore the missing functions. The effort reflects growing frustration among users who bought the machines on the strength of future connected services. It also puts pressure on Vorwerk to account for what happens when cloud support disappears without the affected capabilities being fully replaced. The Vacoola initiative gives owners a potential route back to the smarter experience described when the products were sold.
