Home appliance robotic system, a tandem of a robotic parking station and a roaming device

A home appliance system for autonomously cleaning surfaces of a home environment, comprising:

• a robotic stationary device, comprising:
• a frame structure;
• at least one sensor;
• at least one actuator;
• a processor;
• a dust intake port, a vacuum motor, an exhaust, a filter, a dustbag, and charging contacts;
• at least a component configured for attaching to a permanent water supply of the home environment;
• a memory storing instructions that, when executed by the processor of the robotic stationary device, effectuate operations comprising:
• actuating, with the processor of the robotic stationary device, at least a motor of the robotic stationary device to autonomously supply water to a robotic roaming device;
• a robotic roaming device, comprising:
• a chassis;
• a set of wheels;
• a motor to drive the set of wheels;
• at least one sensor;
• at least one actuator;
• a component for navigation;
• a processor;
• a first set of components for a first data communication mechanism;
• a second set of components for a second data communication mechanism,
• different from the first data communication mechanism;
• a memory storing instructions that, when executed by the processor of the robotic roaming device, effectuate operations comprising:
• receiving and transmitting data from and to the robotic stationary device with the first data communication mechanism;
• receiving and transmitting data from and to a wireless network connected to the internet with the second data communication mechanism;
• wherein the home appliance system is configured to autonomously clean at least one component of itself with an actuated rubbing motion between a component of the robotic stationary device and a component of the robotic roaming device.
