A new $1,000 Roomba passed the mop test. Its app couldn’t keep track of it.
A review of iRobot's newest combo robot found strong vacuuming and mopping, and an app that periodically lost track of the robot mid-clean.
The iRobot Roomba Max 775 Combo cleaned a 750-square-foot apartment in 39 minutes on its first run, one review found. Mapping the space took about 11 minutes. iRobot’s own spec sheet claims roughly 9 minutes for a room nearly a third larger.
A full vacuum-and-mop cycle finished in two and a half hours, with 36 percent of the battery left. The Roborock Qrevo 2 Pro finished a similar cycle in two hours, with 40 percent remaining.
The vacuuming pass left little debris behind and rarely snagged cords, catching only two during the whole test. Mopping fared even better. The roller left hard floors streak-free, and the reviewer rated it close to pricier machines like the Matic and an Ecovacs Deebot X12 model.
Two problems showed up in the same test. The companion app periodically lost track of the robot’s position during longer runs, dropping it off the live map. On a low-pile rug, the robot’s ultrasonic carpet sensor sometimes failed to recognize carpet and mopped across it anyway.
The robot also got stuck once under a child’s bed. Its dock drew a specific complaint: the high-pitched whine it makes while washing the mop roller “interrupts a conversation,” the reviewer wrote.
The Max 775 Combo has been for sale since May 2026, in the same roughly $1,000 tier where Roborock, Dreame and Ecovacs already compete on suction and mopping. This is not a prototype or a future promise. If you are shopping that price band today, the exact robot this review describes is one you can buy right now.
Both problems surfaced inside one reviewer’s test, which ran a few days in one apartment. Does the app lose the robot in a home bigger than that, or the carpet sensor miss a different rug? No published owner account yet says. A short test can find a flaw. It cannot say how often that flaw comes back.
