After years of testing robot vacuums, there are all sorts of inconveniences I have grown to accept as part of owning and using one. They get stuck on string. Sometimes they fall off steps. But all those hassles fell away with Roborock's midrange Q5+ (9/10, WIRED Recommends). After years, it's still the most reliable cleaning partner in my house and the one I call on when other robot vacuums have failed.
It mapped 850 square feet of my home on the first run for 110 minutes, with plenty of battery left to spare. It methodically ran around the rim of the room before vacuuming it in rows, navigated neatly around kitchen chairs, didn't fall off the step in front of the fireplace, and marked everything accurately on the map. It can save and customize up to four separate maps, which means I can simply pick it up and carry it upstairs or to the basement. Adding Siri voice commands is simple, and I can yell at it to start from over 50 feet away.
I have one gripe, which is that the onboard bin is still pretty small. You can make up for this by increasing the emptying frequency and power in the app, or setting up different zones so it empties after each room. However, it did pick up tumbleweeds of dog hair and adroitly swiped croissant crumbs from under the kitchen counter that other vacuums had left behind. I can ignore it—which is the highest praise you can give to any vacuum, ever.
