Dreame Robot aspirateur L20 Ultra

How does the MopExtend technology work?

MopExtend uses position-sensitive detectors to identify edges and corners automatically. When the robot approaches walls or furniture, the mop pads extend outward to clean areas that standard circular robots cannot reach. This technology ensures thorough cleaning of baseboards and tight spaces that are typically missed during regular cleaning cycles.

What happens when the robot encounters carpets whilst mopping?

The L20 Ultra features ultrasonic carpet detection that identifies carpet surfaces automatically. When carpets are detected during a mopping cycle, the robot returns to its base station to remove the mop pads completely. This prevents water damage to carpets and ensures only appropriate cleaning methods are used on different floor types.

How often does the base station need manual maintenance?

The fully automatic base station handles most maintenance tasks independently, including emptying the dustbin, cleaning mop pads and refilling water tanks. You'll need to empty the base station's waste container approximately every 60 days and refill the clean water tank every few weeks, depending on usage frequency and home size.

Can the robot clean multiple floor types in one session?

Yes, the L20 Ultra automatically adjusts its cleaning method based on surface type. The AI navigation system recognises different floor materials and switches between vacuuming and mopping modes accordingly. On hard floors, it vacuums first then mops, whilst on carpets it increases suction power and avoids mopping entirely.

How accurate is the obstacle avoidance system?

The 3D structured light obstacle avoidance system combined with AI Action can identify up to 55 different object types. This includes furniture, cables, shoes and pet toys. The system creates detailed maps of obstacles and plans efficient cleaning paths around them, significantly reducing the chance of collisions or getting stuck.

What is the cleaning coverage area on a single charge?

The L20 Ultra can clean large homes on a single charge, though exact coverage depends on floor type, suction settings and obstacle density. The robot automatically returns to its base station when the battery runs low, recharges, then continues cleaning from where it left off until the entire mapped area is complete.

How does the app control system work?

The Dreame app connects to your robot via Wi-Fi, providing complete control over cleaning schedules, suction levels and cleaning modes. You can view real-time cleaning progress, set virtual no-go zones, receive maintenance alerts and access detailed cleaning reports. The app works from anywhere with internet connection.

What warranty coverage is included with the L20 Ultra?

Dreame provides a comprehensive 3-year warranty covering manufacturing defects and component failures. This extended warranty period demonstrates the manufacturer's confidence in build quality and provides peace of mind for long-term ownership. Warranty terms cover the robot, base station and included accessories.
