Outdated Product
The Dreame company's robot vacuum belongs to the mid-price segment and is a versatile assistant for both dry and wet cleaning in the home. With a high suction power of 13000 Pa, it easily picks up dust, crumbs, fur, and hair from any floor coverings, including carpets. The DuoScrub floor washing system includes two round attachments with soft fibrous wipes, which during operation are tightly pressed against the floor and rotate at high speed to better tackle dirt. Moreover, one of the mops extends beyond the body to thoroughly clean corners and other hard-to-reach places. Upon detecting carpet, the robot automatically increases suction power and raises the wet cleaning attachments by 10.5 mm to avoid leaving wet marks. A capacious 5200 mAh battery provides up to 260 minutes o...f autonomous operation on a single charge, enough to clean a large apartment or house. After cleaning, the Dreame Bot D20 Ultra returns to the docking station, which automates maintenance of the device. It unloads collected debris from the dustbin, washes the mop attachments, and dries them with hot air to prevent mold and unpleasant odors. For this, the station is equipped with a 4.5-liter clean water tank, a 4-liter dirty water tank, and replaceable 3.2-liter garbage bags. The Smart Pathfinder technology ensures precise navigation: laser sensors help the robot accurately measure distance, plot efficient routes, create detailed maps, navigate spaces, and identify obstacles in its path to avoid collisions. The vacuum can also create and memorize maps of multiple floors. Control is carried out via the proprietary mobile app, where you can set up a cleaning schedule, adjust parameters, and define no-go zones. Thanks to support for virtual assistants Alexa, Siri, and Google Home, the robot also understands voice commands.
