Xiaomi Robot Vacuum H40 UK

The Xiaomi Robot Vacuum H40 is a powerful, smart cleaning companion designed for modern homes. Its compact round body (≈340 mm diameter × 97 mm height) slips under furniture and navigates tight spaces with ease, while high-precision LDS laser mapping builds an accurate 3D map of your rooms for thorough, efficient coverage. With up to 10,000 Pa suction, anti-tangle brushes, and adaptive suction control, the H40 lifts dust, hair, and debris from hard floors and carpets to keep your surfaces spotless with minimal effort.

Engineered for convenience, the H40 combines vacuuming and mopping in one pass using an electronically controlled water tank for adjustable flow. The large 5200 mAh battery powers up to 180 minutes of cleaning before the robot automatically returns to charge and then resumes where it left off. An auto-empty dock with a 4 L dust bag handles disposal for weeks at a time, while the Xiaomi Home app lets you schedule, zone clean, and set no-go areas—making everyday cleaning smarter and hands-free.
