The main difference between the QR 598 (Robot Vacuum Cleaner) and the Qrevo series lies in the mopping technology and docking station functions. The Qrevo models have dual rotating mopping pads that lift when carpet is detected and specialised docking stations that automatically empty the dust bin and maintain the mopping pads. In addition, higher-end Qrevo models offer advanced brush systems, higher suction power and advanced obstacle detection. The QR 598 has a strong suction power of 8000 Pa, automatic functions such as water refill and mop pad drying, but no dual rotating mops or the specialised Qrevo docks.

To summarise:

- Qrevo: Dual rotating mops that lift up on carpets, specialised docking station for automatic emptying and mop pad maintenance, advanced brush systems, higher suction power, innovative obstacle detection.

- QR 598: High suction power (8000 Pa), automatic water refill and mop pad drying, laser navigation, carpet detection, but no dual rotating mops or specialised docking station.

The Qrevo series is overall more sophisticated in mopping function and maintenance, while the QR 598 is a powerful vacuum mopping robot with solid automatic functions, but without the specialised Qrevo features.
