In this product demonstration, Karthik, a mechanical engineer at Matic, explains the design and operation of Matic's waste bag for its robot vacuum. The bag features HEPA‑12 grade filtration and a dual‑layer construction—fabric on top and a thin plastic film on the bottom—to provide strong airflow while keeping liquid sealed. To maintain hygiene and odor control, the bag incorporates antibacterial powder, lemon scent, and a water‑gelifying salt that prolongs freshness. Embedded sensors monitor bag fullness in real time, allowing the robot to adjust suction power and notify users when the bag reaches capacity. The replacement process is designed to be completely hands‑free: the user opens the lid, slides the used bag out, and clicks a new bag onto rails, never touching the debris. Karthik emphasizes the hygienic, user‑friendly experience and the engineering choices that enable it.

Hello, my name is Karthik and I'm one of the mechanical engineers at Matic. I helped design the waste bag at Matic and today we're going to talk more about it. So Matic's waste bag provides HEPA 12 grade filtration and it can hold variety of debris from like dry debris like pet hair to dust particles to wet debris that we also collect back from our mopping feature. And the way it's being done is through the combination of different materials here. So at the top we have the fabric, and on the bottom we have a thin plastic film. And this allows us to have ample airflow suction during vacuuming and also to keep the water inside the bag leak tight. In addition to that, we also added antibacterial, antibacterial powder, lemon scent, and also water gelifying salt. Which keeps the bag fresher and cleaner for a long duration of time. Inside the robot, we have a range of sensors that basically tells us the fullness of the bag during vacuuming, and we basically adjust our vacuum and suction depending on how much the bag is full. And at one point, when the bag is like full to its capacity, we tell the customer to like take the bag out, and we just replace the bag with a new one. And replacing action is also very simple. So you open up the lid, you take the bag out, and it basically closes at the front, at the top, and then you throw this bag in the trash can. So at no point in the entire interaction you're actually touching the dirt or any kind of debris. So we keep the entire experience clean and hygienic. Thank you. And the way to reinstall a new bag is just take the bag in, there are rails provided on the bin, and just put it here. It's gonna click in and close the lid.
