Automatic Water Management and Compact Design

The X40 Master features automatic refilling and draining functions facilitated by an 8-in-1 hands-free base station. This hub not only manages water but also handles tasks like self-cleaning, self-drying, and self-emptying, reducing the need for manual maintenance. With a low-profile design standing at 11 inches tall, the station is intended to fit seamlessly into homes.

Advanced Cleaning Reach

In terms of cleaning reach, the device’s side brush extends over 0.39 inches, allowing it to access corners and under furniture. Additionally, its MopExtend RoboSwing technology enables the robot to reach up to 1.57 inches into low-clearance spaces.

High Suction Power and Intelligent Dirt Detection

Much like the Dreame X40 Ultra, the X40 Master is equipped with a suction power of 12,000 Pa, designed to remove various types of debris. It also incorporates OmniDirt Detection technology, which uses color sensing and dirt detection mechanisms to adapt its cleaning approach based on the type of mess encountered. For particularly dirty areas, the robot can automatically perform additional mopping passes and rewash its mops autonomously.

Optional TriCut Brush for Hair Management

An optional feature available for the X40 Master is the TriCut brush, sold separately. This accessory is designed to manage human and pet hair by automatically cutting and directing it into the dust box, potentially reducing the need for manual cleaning of the brush roll.
