Dreame is well known for making some of the best robot vacuums and hair stylers around, but it also has a sideline in coffee machines — and they’re every bit as good as the rest of its appliances. This week I’m testing its new portable espresso machine, the Dreame Ecceluxe Go, and I think this pint-sized brewer is going to be my new favorite travelling companion. Of course, there’s no shortage of travel-friendly coffee makers available, from the classic AeroPress to the hand-pumped Wacaco Nanopresso . The problem is, they all need to have hot water on hand, which isn’t always feasible. Who wants to set up a camping stove and kettle for one drink — and who has the patience?
