Roborock S8 Pro Ultra Robot Vacuum and Mop

The S8 Pro Ultra is an all-encompassing solution to clean your home. It vacuums, mops, and self-empties. It dries its mop to prevent mold and mildew from forming. As for the self-emptying of the dirt, that happens due to the large dust bag that allows up to a whopping seven weeks of dirt accumulation! Even the RockDock Ultra cleans itself, refilling the water tank for you to extend the mopping range to 3,230 square feet.

Self-emptying modes

The self-emptying modes include:

  • Smart
  • Light
  • Balanced
  • Max

As for the washing modes, they include light, balanced, and max with drying modes that include two, three, or four hours.

Double cleaning method

Thanks to Roborock’s newest dual rubber brush system, cleaning happens to a higher extent in only one go, and hair tangling happens less frequently. The likes of hair, dust, and debris are picked up while moving seamlessly between floors and carpets despite thresholds in between them.

VibraRise 2.0 Mopping System

This mopping system is there to upgrade the vibration module from one area to two areas (through two vibration modules) in order to guarantee a wider 50 Hz dual sonic mopping zone with up to 3,000 times per minute of high speed scrubbing. Furthermore, there are more than 6 Newtons of consistent mopping pressure so that stains are cleaned for sure.

Lift-able brush & mop

In order to separate vacuuming from mopping, the DuoRoller Riser brushes will lift whenever needed, and the mop will be lifted by 5 mm on low-pile carpets when needed too, operating alongside the Roborock Carpet Boost+ System for enhanced carpet suction. You see, on a carpet, you would not want your S8 Pro Ultra to mop.

Now, for very high thresholds that are otherwise tough to climb, both the brushes and the mop can be lifted. However, the mop cannot be lifted that high. It would have been nice to be able to remove the mop holder.

Reactive 3D Obstacle Avoidance

This technology involves 3D structured light and infrared image technology, which makes the S8 Pro Ultra intelligent enough in order to pick out unknown objects on your floors to then determine their location and size, enabling a smooth bypassing of them, even if it is dark. Add to that LiDAR navigation & detailed 3D Mapping 2.0, and you are good to go, amigo!

Advanced smart control

You can control the S8 Pro Ultra in different ways, such as by way of the user friendly Roborock App, letting you:

  • Control the S8 Pro Ultra completely.
  • Engage auto-emptying mode.
  • Activate mop washing-and-drying mode.
  • Adjust suction.
  • Adjust water flow.
  • Schedule a cleaning.
  • Add furniture to the layout.

Up to four levels of your home can be recognized. This Roborock robot cleaner can even suggest setting no-go zones where easy-to-get-stuck areas are.

Another way to control the S8 Pro Ultra is by way of voice control, including Amazon Alexa, Google Home, and Siri Shortcuts.

About charging

The S8 Pro Ultra charges quite fast, meaning in four hours, which are supposedly 30% less than average. The runtime is a good three hours in quiet mode, guaranteeing the cleaning of most homes. If you know your off-peak times, you can set them in order to charge and save on power, saving you from hefty electricity bills.


The S8 Pro Ultra is a worthy sequel to its critically acclaimed predecessor and is a contender for the world’s best!
