We received the device including a battery. The one battery can (must) be changed back and forth between the devices. Just like the motor. It would be strange if the appliance was delivered inoperable. Changing works well. But it remains to be seen how long it will last.

I also asked myself this question and asked customer service directly in the app. Yes, there are spare parts. The official answer: Hello, Thank you for contacting us. You can purchase the "extension bar" separately from our customer service team. Unfortunately, it is not possible to connect two extension rods together. You can order other spare parts and wearing parts on our official Swiss website. Free service number: +49 800 000 1747 (Monday-Friday 9:00-21:00 Saturday-Sunday 9:00-18:00) E-Mail: aftersales@dreame.tech Thank you for your support and understanding.

The difference between the H15 Mix and H15 Pro Heat lies primarily in the technology and features: - The H15 Pro Heat is a stand-alone wet cleaner with a more powerful function that uses hot water up to 85-90 °C for cleaning, which is particularly helpful against dirt and odours. It has a suction power of 21,000 Pa and a battery life of around 60 minutes. - The H15 Mix consists of several parts, but is not a Pro or Pro Heat model per se, but rather a variant or set based on the H15 technology. In terms of performance, the H15 Mix cannot be equated with the Pro or Pro Heat. - Compared to the normal H15 Pro, the H15 Pro Heat also offers the hot water function, which the H15 Mix does not have. - Both Pro models have an intelligent squeegee lip for better edge cleaning, while the H15 Pro Heat also has a remote control option. Regarding the fitting of a dog hairbrush analogue to Dyson: There is no official information that a special dog hairbrush can be fitted to one of the models. Compatibility with such brushes has not been confirmed and is unlikely to be standard.

Unfortunately, we do not currently offer any additional battery packs for this product.
