Summary of YouTube Video: Roborock QR798 vs. Q Revo S

Key Concepts:

• Roborock QR798: New robot vacuum model replacing the Q Revo S.
• Q Revo S: Previous generation robot vacuum.
• Automated features: Self-washing, self-drying mops, auto-emptying dustbin.
• Suction power: Measured in Pascals (Pa).
• Obstacle avoidance: Using structured light sensing.
• Ultrasonic sensor: Detects carpets and adjusts cleaning settings.

1. Introduction and Overview of Roborock QR798

• The video introduces the Roborock QR798 as a new robot vacuum cleaner, positioned as a replacement for the older Q Revo S model.
• A key selling point is its affordability, with a price around 9 million VND during promotions, offering full automation features previously unavailable at this price point.
• The video aims to highlight the significant differences between the QR798 and the Q Revo S.
• The review is sponsored by Roborock.

2. Design and Features of QR798

• The QR798 features a similar design to previous Q Revo models but with a new naming convention.
• It includes standard vacuuming and dual spinning mop features.
• The most important feature is the dock, which provides automatic mop washing, mop drying, and dustbin emptying.
• The dock includes clean and dirty water tanks, and a dustbin.
• Previously, such comprehensive features were only available in higher-priced models (15-20 million VND), but the QR798 offers them at around 10-11 million VND.
• The automated features reduce user intervention, eliminating the need for manual mop washing, drying, and attachment.
• The water tanks require refilling/emptying every 2-3 days for a 50-60 m² area.

3. Key Differences Between QR798 and Q Revo S

• Side Brush Design: The QR798 features an offset side brush design, unlike the symmetrical three-pronged brush of the Q Revo S. This new design is intended to reduce hair tangling.
• Mop Pads and Main Brush: The mop pads and main brush are similar in both models. The main brush is designed to minimize hair tangling.
• Ultrasonic Carpet Detection: Both models have an ultrasonic sensor to detect carpets, automatically increasing suction power and lifting the mop pads to avoid wetting the carpet. This eliminates the need for manual carpet zoning in the app. The reviewer emphasizes that this feature is essential for robot vacuums in the 10 million VND price range.
• Other Sensors: Both models include standard sensors like anti-fall and collision sensors.
• Suction Power: The QR798 has a maximum suction power of 10,000 Pa, compared to 7,000 Pa for the Q Revo S. However, the reviewer notes that the maximum suction power is rarely needed, and automatic or medium settings are usually sufficient.

4. Obstacle Avoidance

• Both models use structured light sensing for obstacle avoidance, which is standard for this price range.
• The system can effectively avoid larger obstacles like shoes but may struggle with low-lying objects like thin cables.
• The reviewer recommends keeping the floor relatively clear for optimal performance.

5. Docking Station Comparison

• The docking stations of the QR798 and Q Revo S are nearly identical.
• Both include clean and dirty water tanks, a dust bag for automatic dustbin emptying, and a filter to reduce odors.
• Both docks feature a removable tray for easy cleaning of the mop washing area. The reviewer recommends cleaning this tray monthly.

6. Noise Level and Battery Life

• The noise levels of both models are similar and generally acceptable.
• Both models have a maximum battery life of 180 minutes, according to the manufacturer.
• Actual battery life depends on factors like carpet area and suction power settings.
• The battery life is sufficient for cleaning homes up to 100 m².
• Both models automatically return to the dock to recharge and resume cleaning if necessary.

7. Conclusion and Recommendation

• The Roborock QR798 is recommended as a compelling option in the under 12 million VND price range.
• The Q Revo S is being phased out, making the QR798 its direct replacement.
• The QR798 offers a good price point and a full suite of automated features, including mop washing, drying, and dustbin emptying.
