Conclusion from 22.07.2025 The Dreame H15 Pro Heat is tested with impressive features, but shows weaknesses in its suction power. With generous water tanks of 0.7 litres for dirty water and 0.78 litres for fresh water, the vacuum cleaner is well equipped. Commissioning and daily use run smoothly. The station with self-cleaning and drying mode is particularly practical, as it saves several work processes. Although the hot water function takes a few seconds to heat up, it proves to be useful. Despite the weight of over 6 kg and 1.34 kg in the hand, the pulling aid provides effective support when mopping surfaces and dries the floor reliably. The appliance has a display, but it does not show the remaining running time. The battery lasts around 40 minutes on the minimum setting and around 30 minutes on the maximum setting, taking more than four hours to charge. The mopping performance is impressive: fresh dirt is removed at an average level, while dry stains are removed excellently. However, the suction power is disappointing; even on the maximum setting, the appliance is barely more powerful than on the minimum setting and only manages to pick up half of the test dust. The Dreame H15 Pro Heat is therefore no substitute for a conventional hoover.
