This is a feature-packed robot vacuum. Overall, it’s similarly equipped to the Roborock Q Revo. Like that model, it has the brand’s Auto-Mop Lift feature, which lifts its mopping pad by 5 millimeters when the vacuum detects that it’s passing onto a carpeted surface, so there’s no need to take off its mopping pads if you want the vacuum to clean carpets and mop floors in the same cleaning job. Unlike that model, however, the Roborock S8 Pro Ultra’s brushrolls can also lift, so they don’t drag on the floor while the unit is running a mopping cycle. There are five different suction power modes: the energy-efficient ‘Quiet’ mode, the default ‘Balanced’ mode, ‘Turbo,’ ‘Max,’ and ‘Max+,’ which is meant for cleaning extremely stubborn debris. There are also a variety of carpet-specific cleaning functions, where it uses its ultrasonic sensor to detect whether or not it’s on carpet: ‘Carpet First’ mode, ‘Carpet Boost’ mode, and ‘Deep Carpet Cleaning,’ the last of which directs the vacuum to only clean carpets after it’s finished cleaning the rest of your home. You can also set it to avoid all carpets or, on the opposite end of the spectrum, disable the carpet-detection function entirely so that it may mop rugs and bare floors. This isn’t desirable for normal carpets, but it’s especially handy for mopping any rubber mats you might have in your home.

There are a variety of mopping options, too. You can choose between three levels of water flow to its mopping pads: ‘Low,’ ‘Medium,’ and ‘High.’ There are also four levels of route mapping settings, which effectively allow you to choose between fast and deep mopping on a sliding scale.

The Roborock S8 Pro Ultra also features Roborock’s Reactive 3D system, which uses a structured light sensor and infrared camera to spot hazards, but this type of sensor ultimately isn’t as sophisticated or as effective as the RGB-color camera-based system found on the Roborock S7 MaxV.
