The main difference between the aforementioned robot hoover and the Dreame X50 Ultra Complete lies in the features and performance. The X50 Ultra Complete is a flagship model with a suction power of up to 20,000 Pa, has advanced navigation with AI-controlled camera, automatic mop cleaning and drying and a docking station with automatic dust emptying and mop handling. It can overcome obstacles of up to 6 cm and has a height of just 8.9 cm, making it easier to clean under furniture. It also supports voice assistants such as Google Assistant, Amazon Alexa and Apple Siri.

The X50 RLX85CE-6-BK (robot hoover) has a battery life of 220 minutes, a maximum volume of 70 dB, a height of 11.1 cm and offers functions such as automatic dust emptying, obstacle detection and self-emptying. It also supports Amazon Alexa and Google Assistant, but has no details on an AI camera, automatic mop cleaning or the ability to overcome high thresholds [product data].

To summarise:

- Suction power: X50 Ultra Complete up to 20,000 Pa, X50 RLX85CE-6-BK no specification, presumably lower
- Navigation: X50 Ultra Complete with AI camera and advanced obstacle detection, X50 RLX85CE-6-BK with obstacle detector
- Mop function: X50 Ultra Complete with automatic mop cleaning and drying, X50 RLX85CE-6-BK without this function
- Threshold overcoming: X50 Ultra Complete up to 6 cm, X50 RLX85CE-6-BK no specification
- Noise level: X50 Ultra Complete approx. 63 dB, X50 RLX85CE-6-BK up to 70 dB
- Height: X50 Ultra Complete 8.9 cm, X50 RLX85CE-6-BK 11.1 cm

The X50 Ultra Complete is therefore technically and functionally much more advanced and designed for more demanding cleaning tasks.
