The CAiRoomba functions as a battery-powered moving vacuum filter that will traverse the house, ensuring no spot is left unfiltered. From the outside, the CAiRoomba is shaped like a rectangular box and lined by mesh, ensuring that it is accident-proof. On the side are holes connected to an open space that contains an axial fan to draw in air. Four sensors will be positioned, one on each side of the machine, to help direct movement and ensure that the CAiRoomba takes in air from new locations as it works.

Inside the CAiRoomba, there will be a rectangular section lined by titanium oxide. Air drawn in from the fan will enter tubes made of titanium oxide. UV light, specifically UVC, will be emitted from the top, utilizing photocatalytic oxidation (PCO) to kill viral particles as well as other dangerous contaminants/volatile organic compounds (VOCs) into water and CO2 molecules which can be used for additional purposes. The CO2 can be funneled into another section of the CAiRoomba to be used to generate more water as well as methane through a Sabatier reaction with hydrogen in the air. The resulting products can be used in their own separate ways. The water from the Sabatier reaction as well as PCO can be sent to another section to be used to produce O2 through electrolysis using the CAiRoomba’s battery power. The methane gas product can be stored in a fuel cartridge connected to a pressure sensor. When near full-capacity, the sensor will signal that the cartridge should be replaced. Alternatively, the methane can be used as fuel to heat homes or generate electricity in the future.

Although UV light can be dangerous, the titanium oxide lining will ensure UV light does not penetrate through the CAiRoomba and will instead scatter, ensuring that the air inside is sufficiently treated. Following the filtration process, the remaining air will be clean and free of contaminants and will be released through the other side of the CAiRoomba. As the CAiRoomba moves around, this procedure will take place across the house, ensuring quality air and protecting those inside.
