Verdict

The MEDION X20 SW is a 2-in-1 robot vacuum and mop featuring an intelligent LiDAR laser navigation system for precision mapping, a variable suction power topping out at 3,000 Pa, and an impressive battery life of up to 150 minutes. Main pros include its self-emptying station featuring a 2.5-litre dust bag capacity, automatic carpet detection with suction boost, dual side brushes for edge cleaning, and versatile app control with Amazon Alexa compatibility. However, potential cons include its structural limitation regarding high door thresholds, a compact 0.25-litre internal dust bin, and a minor operational dependency where user assistance is needed if it encounters dense loose cables.
