Roborock Q Revo Master Review | TechManPat

FlexiArm cleaning reaches the edges

The Q Revo Master’s standout feature is FlexiArm technology. Both the mop and brush can extend from the robot, allowing them to reach closer to walls and into corners. The extending components create what the video describes as a 90 degree cleaning angle, while the mop pads overlap their cleaning paths to reduce missed areas between them.

The review found the mopping performance particularly effective when cleaning a thick, dark coffee spill. The robot was directed to clean the area and completed the task within a few minutes. One limitation was that it could not fit under the kickboard in the tested area, due to the robot’s height.

Vacuuming and mopping performance

Underneath, the Q Revo Master uses dual rubber rollers that move up and down to stay close to different floor surfaces. Suction is rated at up to 10,000Pa, with the highest level automatically selected when the robot moves onto carpet. The review found the vacuuming effective against dirt, debris and pet hair.

The mop pads spin and apply some pressure to the floor while cleaning. They also lift when moving over carpet, helping to prevent wet mops from touching it. The app can be set to vacuum before mopping, and the robot can lift its mops when passing back over an area it has already cleaned.

Docking station and maintenance

The Multifunction Dock 3.0 washes the mop pads with hot water, dries them with hot air at up to 60 degrees, empties the robot and refills its water supply. The dust storage is described as lasting about seven weeks. The video also says the heat-based washing and drying process removes 99.7 percent of bacteria and helps prevent mould and odours.

Maintenance is still required. The dust bag needs replacing approximately every six to seven weeks, and the clean water tank needs regular refilling. The removable section beneath the dock makes it easier to clean the area where the mop pads are washed. The review recommends washing the mop pads every two to four weeks, depending on the floors in the home.

The rubber rollers include hair-cutting blades near their edges. Hair is directed towards the sides of the rollers, where it can be cut and then collected, rather than forming a large central clump. Some hair can still remain on the edges, so the robot is not maintenance-free.

Navigation, app and battery results

The Q Revo Master uses reactive AI obstacle recognition with light and RGB cameras, as well as LiDAR navigation. The review describes its navigation as among the best seen across the Q Revo range. It can create a detailed map, adjust routes when furniture or other objects move, and avoid many obstacles without requiring extensive preparation.

However, small objects can still cause trouble. The review observed the robot becoming caught on shoelaces and small cables, including USB chargers, and also reported that it picked up Lego. Users will still need to clear these items from the floor.

The Roborock app supports schedules, virtual boundaries, no-go zones, live progress monitoring, maps, suction settings, mopping intensity and targeted cleaning modes. In the reported test, the robot cleaned 74 square metres in 97 minutes, washed the mops three times and returned with approximately 28 percent battery remaining. It was also used on a separate level by moving it manually, after which it returned to where it started.

Limitations and overall positioning

The main drawback identified is the higher price, which reflects the premium features and FlexiArm system. The robot also requires ongoing attention for water, dust bags, mop washing and general cleaning. Its obstacle recognition is strong, but it cannot reliably deal with every small cable, shoelace or toy left on the floor.
