Using a commode is a better option than going to the bathroom every time the need to urinate strikes. The portability of a medical commode makes it an excellent choice for individuals who are confined to a wheelchair or bed or who have restricted mobility.The vacuum technology in portable restrooms uses air instead of water to transport sewage. This advantage significantly reduces water usage. It also allows the airflow to vent away odors. Not least, this process dramatically reduces the risk of spreading airborne and waterborne pathogens.
