As the market for robotic vacuums continues to expand, “decentralizing flagship technology” and providing “premium features at mid-range prices” has been a primary trend. Stone Technology’s latest model, the Roborock P20 Ultra, is representative of this trend. Priced between $400 and $550, the P20 Ultra integrates high-end features like lifting LDS laser navigation, ultra-slim body, self-cleaning base station, and intelligent interaction technology, rewriting the rules for mid-to-high-end robot vacuums.
Two of the standout features of Roborock P20 Ultra are its slender 7.98 cm body and industry-leading chassis lifting technology. Both innovations eliminate the common vacuum cleaning challenge in low-clearance environments and complex terrains, offering unparalleled ease of use for the consumers. The slender body enables the P20 Ultra to vacuum under sofas and beds, while the chassis lifting technology enables it to flow smoothly over the obstacle as high as 4 cm, way above industry benchmarks.
Besides, the P20 Ultra comes with enhanced mopping at 12N dynamic pressure and 80°C heat mopping technology that can effortlessly wipe away stubborn stains without over-wetting the floor. Its self-cleaning base station makes maintenance a breeze, with high-temperature cloth washing and a self-driven chassis cleaning system that requires minimal maintenance.
Appearance
The Roborock P20 Ultra robot vacuum and mop boasts a minimalist design with a pure white body that gives it a clean and sleek appearance. Its laser head, pressure sensor, and laser ranging sensor all automatically retract in standby mode, maintaining its sleek appearance.
The front of the Roborock P20 Ultra is minimalist, with just a cleaning button and a power button. It also has three internal microphones for detecting voice commands. A height sensor above the buttons tracks the robot’s height in real time, so it will not get stuck in narrow areas and clean smoothly.
At the front, the P20 Ultra features obstacle avoidance sensors, charging sensors, and an onboard camera for real-time monitoring of the cleaning. On the bottom, it has a pressurized mop spinning at 200 rpm with 8N of force to lift stubborn stains even in hot water.
Both the main and side brushes are of double-conical spiral in structure, which prevents hair entanglement and problems such as jamming. Powerful 22,000 Pa suction force and washable universal wheels enable effortless cleaning with Roborock P20 Ultra.
Its base station, which features sleek lines and a contemporary look, will blend into any living room. It includes a disposable dust bag, clean water tank, and dirty water tank for convenience.
Cleaning experience
3D Mapping
Before starting to clean, the Roborock P20 Ultra quickly maps the space. In a room around 10 square meters, the mapping process is completed in under 2 minutes. Additionally, its 3D mapping feature can automatically identify furniture types and adjust its cleaning route for maximum efficiency.
Cleaning Experience
The Roborock P20 Ultra delivers powerful suction up to 20,000Pa, with five suction levels: Quiet, Standard, Strong, Max, and Max+. Max+ mode is ideal for deep cleaning but consumes more power and generates more noise, so the first four modes are recommended for daily use. Standard mode efficiently handles common household debris and hair.
In our tests, the Roborock P20 Ultra easily removed dry debris like seed shells and dust in Standard mode. For regular cleaning, Standard or Quiet mode is sufficient, especially if cleaning daily.
Mopping Performance
The Roborock P20 Ultra’s dynamic pressure rotary mop operates at 12N of pressure and uses 80°C hot water for constant humidity. The mop rotates at 200 rpm to effectively tackle stubborn stains while maintaining close contact with the floor for thorough cleaning.
Its constant-humidity technology keeps the mop moist and sterilized at 80°C, which helps clean both dry and wet debris efficiently. This system ensures stains are removed without leaving residue, with just a couple of passes.
Additionally, the P20 Ultra supports dynamic hot water re-mopping. Equipped with dirt detection, it checks the cleanliness of the mop and floor during the process. If it detects dirt, it returns to the base station to clean the mop before resuming. This intelligent feature ensures a spotless clean without manual effort.
Mechanical Side Brush Extension
The Roborock P20 Ultra features a dual-arm system with a telescopic robotic arm for side brushing and dynamic mopping. This design enables the robot to clean hard-to-reach areas and corners, ensuring comprehensive coverage.
When cleaning edges or corners, the mop extends outward, applying 12N of pressure. The side brush also extends to sweep debris into the vacuum, even in tight corners, ensuring 100% corner cleaning coverage.
The side brushes automatically retract to avoid scattering debris or hitting obstacles, providing an efficient and worry-free cleaning experience. Its TÜV Rheinland-certified corner cleaning has an impressive 99.5% coverage rate, ensuring hands-free cleaning.
Lifting LDS and Low-Area Cleaning
Thanks to its ultra-thin 7.98cm body and liftable LDS system, the Roborock P20 Ultra can easily clean low-lying areas like under sofas and beds. This design allows it to reach more challenging areas, expanding its cleaning versatility.
Obstacle Test
When encountering a 2cm threshold, the Roborock P20 Ultra’s wheels work together to lift the chassis, easily crossing the threshold without scratching the robot’s body. In our tests with a 4cm threshold, the P20 Ultra made two attempts to raise the chassis and successfully crossed the barrier, showcasing its ability to handle higher obstacles.
Self-cleaning experience
Dust Collection
When the Roborock P20 Ultra returns to the base station, the first task is automatic dust collection. After a cleaning session, the dust box, filled with debris like melon seed shells, is emptied without requiring manual intervention, making daily maintenance easy and hassle-free.
Mop Cleaning
The mop, initially stained with tough spots like soy sauce, underwent dynamic rinsing with 85°C hot water. This deep cleaning process, lasting 5 to 6 minutes, effectively removed even stubborn oil stains, leaving the mop spotless. The result was a visibly clean mop, showing a stark contrast to its initial condition.
Automatic Drying
After washing, the Roborock P20 Ultra starts its automatic drying process, with a default drying time of 3 hours. Hot air is blown continuously at a 45-degree angle to dry the mop and the base station thoroughly. The mop also lifts slightly to ensure proper ventilation and avoid odors, mold, or mildew, maintaining a fresh, clean base station environment.
Conclusion
Amid fierce competition in the sweeping robot industry, the Roborock P20 Ultra stands out by addressing common cleaning challenges like threshold navigation, low-area cleaning, and removing stubborn stains. Its 7.98cm ultra-thin design allows it to clean under beds and sofas, providing full-house coverage without missing any spots. The dual-view LDS system enhances navigation accuracy, avoiding collisions with low furniture.
The automatic lifting chassis enables it to cross thresholds effortlessly, reducing the need for manual intervention. With 22000Pa suction power, it removes dust and hair from deep within carpets, while the 80°C heated mopping and high-frequency vibration mop handle tough stains like coffee and oil.
Additional features, like the spiral main brush that prevents hair entanglement, further optimize the cleaning experience. Delivering flagship-level performance at a mid-range price, the P20 Ultra is a top contender in the market for seamless, intelligent home cleaning.
