  "description_excerpt": "The present disclosure is directed to robotic laundry devices, systems, and methods.\n\nAutomating and outsourcing mundane, time-consuming household chores to robotic devices is increasingly common. Time-saving home robots include, for example, floor vacuuming and floor washing robots. Outsourcing responsibilities include, for example, engaging grocery shopping and delivery, and manually operated and human-operator dependent laundry washing and dry-cleaning pick up and return services.\n\nMany homes are appointed with a dedicated washer and dryer for family use. Domestic washers and dryers are increasingly sophisticated and include IoT connectivity features and push notifications for alerting users about cycle progress and energy and resource usage. These technologically advanced machines, however, require human interaction and cannot eliminate the time and manual labor required for processing loads of laundry in the home. Although more modern, “high efficiency” machines are equipped with sensors for metering water usage and dryer temperatures, the efficiency gains are capped by the constraints of sequentially processing single loads of laundry. Additionally, grey water is output to the city water and sewer system for mitigation with each load of laundry processed, and energy is consumed with each load of laundry washed and dried.\n\nHouseholds can outsource laundry chores to laundromat facilities for a fee in exchange for time.",
