H15 Pro Heat uses 85°C (185°F) hot water to rinse the brush roller, achieving 55°C (131°F) hot water floor washing. Additionally, our newly developed cleaning solution is compatible with hot water and results in triple cleaning efficiency to easily manage heavy dirt and stains, including tough messes like kitchen oil, while causing little to no damage to wooden floors. H15 Pro Heat's upgraded brush boasts the TangleCut resilient scraper with durable Swiss PPA-bladed comb teeth. This advanced design precisely severs hair tangles as they are vacuumed, leaving the brush tangle-free and saving you from manual detangling troubles. H15 Pro Heat's RGB dirt detection is 5x more sensitive than previous models. It can recognize a wide range of dirt and stains, automatically adjusting its suction power based on the type of mess encountered. Whether solid crumbs or thick liquid, this advanced system can detect dirt types when vacuuming, ensuring optimal cleaning without exerting extra effort on scrubbing. H15 Pro Heat raises the cleaning game with its 22,000Pa suction power, up to 72 minutes of runtime, tackling various messes efficiently, wet or dry, surface or ground-in. No mess is too tough, from spaghetti and coffee beans to annoying kitchen grease. Experience hands-free cleaning via Dreamehome App control by placing the vacuum lying down and controlling it like a robot vacuum. Guide your vacuum forward and backward; the two rear GlideWheel will respond and guide the vacuum's movement. It can fit into spaces as low as 13cm (5.12in) for the body and 8.9cm (3.5in) for the brush head, making cleaning in lower spaces more energy-efficient and helping to reach further comprehensive cleaning.
