iRobot has unveiled two new robot vacuum and mop models featuring a new carpet-sealing technology called SealForce.

iRobot has introduced two new flagship robot vacuum and mop models, the Roomba Max 875 Combo and the Roomba Plus 678 Combo. The company is showcasing the new devices at the IFA trade show in Berlin. These are the first major product releases since the company was acquired by contract manufacturer Picea Robotics earlier this year.

New SealForce Cleaning Technology

The primary feature of the new models is SealForce, a system that lowers a skirt around the cleaning head when carpet is detected. This creates a seal that directs airflow deeper into the carpet fibers. According to iRobot chief engineer Adam Pope, the system allows the Roomba 875 to deliver three times deeper carpet cleaning than previous iterations. The 875 model features 35,000 Pa of suction power and a vane-type blower motor that moves 20 liters of air per second.

Mopping and Additional Features

The Roomba 875 includes a self-cleaning roller mop system with a heated mist feature called ThermaMist, which pretreats stains. It also comes with an auto-empty and wash dock that cleans the mop with hot water and dries it with hot air. The midrange Roomba 678 model uses a different system called SprayForce, which sprays cleaning fluid on stains before mopping. Both models are compatible with Amazon Alexa, Google Home, and Siri Shortcuts, and are currently undergoing Matter certification.
