1. A mop module of a robotic surface cleaning device, the module comprising:
a frame, further comprising:
a liquid reservoir having liquid therein, and
a control mechanism for controlling a release of the liquid from said liquid reservoir,
a drainage mechanism positioned below the frame,
wherein:
the release of the liquid from said liquid reservoir by said control mechanism is controlled by a motion of said robotic surface cleaning device,
a rapidity of said release of the liquid from said liquid reservoir is proportional to a speed of said robotic surface cleaning device,
the release of the liquid from said liquid reservoir by said control mechanism is controlled by a rotary motion of one or more non-propelling wheels of said robotic floor cleaning device,
the release of liquid from said liquid reservoir is solely controlled by the motion of said robotic surface cleaning device,
said mop module is configured to be positioned within a chassis of said robotic surface cleaning device, and
at least one component of said mop module is detachable from said chassis.
