and a mop module including a cleaning pad configured to mop the flooring surface when the mop module is installed in the cavity, the mop module user-securable to the cavity of the body. ### Claim 3 (depends on 2) The mobile cleaning robot system of claim 2, wherein the mop module includes a fluid supply system including an applicator configured to dispense a cleaning fluid on the flooring surface. ### Claim 4 (depends on 3) The mobile cleaning robot system of claim 3, wherein the fluid supply system includes: a reservoir configured to contain a supply of the cleaning fluid; and a pump to deliver the cleaning fluid from the reservoir to one or more of the cleaning pad and the flooring surface. ### Claim 5 (depends on 4) The mobile cleaning robot system of claim 4, wherein the fluid supply system includes a shaft connectable to a drive gear of the mobile cleaning robot when the mop module is installed in the cavity, the shaft configured to be driven by the drive gear to operate the pump. ### Claim 6 (depends on 4) The mobile cleaning robot system of claim 4, wherein the mop module includes an agitation system operable to forcibly move the cleaning pad relative to the mobile cleaning robot to scrub the flooring surface with the cleaning pad. ### Claim 7 (depends on 2) The mobile cleaning robot system of claim 2, wherein the body includes a seating located between a front portion of the mobile cleaning robot and a rear portion of the mobile cleaning robot, the seating configured to receive the mop module to allow the mobile cleaning robot to perform mopping operations when the vacuum module is not installed and to receive the vacuum module to allow the mobile cleaning robot to perform vacuuming operations when the mop module is not installed. ### Claim 8 (depends on 7) The mobile cleaning robot system of claim 7, wherein the mobile cleaning robot includes: a lid connected to a top portion of the body, the lid movable between a closed position and an open position, the cavity user-accessible to install or remove the mop module or the vacuum module from above the mobile cleaning robot when the lid is open, and the cavity enclosed from above the mobile cleaning robot when the lid is closed. ### Claim 9 (depends on 8) The mobile cleaning robot system of claim 8, wherein the mobile cleaning robot includes: a hinge connected to the body and the lid to allow the lid to hingeably move between the open position and the closed position. ### Claim 10 (depends on 8) The mobile cleaning robot system of claim 8, wherein the mobile cleaning robot includes: a module sensor connected to one or more of the lid and the body configured to generate a signal based on one or more of a presence or absence of one or more of the mop module and the vacuum module. ### Claim 11 (depends on 10) The mobile cleaning robot system of claim 10, wherein the mobile cleaning robot includes: a controller connected to the body and configured to determine whether the mop module and the vacuum module are installed in the cavity. ### Claim 12 A mobile cleaning robot system configured to clean a flooring surface of an environment, the mobile cleaning robot system comprising: a mobile cleaning robot comprising: a body including a cavity; and a drive system connected to the body and operable to move the mobile cleaning robot about the environment; a vacuum module including an extractor operable to extract debris from the environment when the vacuum module is installed in the cavity, the vacuum module user-securable to the cavity of the body; and a mop module including a cleaning pad configured to mop the flooring surface when the mop module is installed in the cavity, the mop module user-securable to the cavity of the body. ### Claim 13 (depends on 12) The mobile cleaning robot system of claim 12, wherein the vacuum module includes a housing and a filter user-removable from the housing. ### Claim 14 (depends on 13) The mobile cleaning robot system of claim 13, wherein the vacuum module includes a lid movable to access the filter. ### Claim 15 (depends on 13) The mobile cleaning robot system of claim 13, wherein the vacuum module includes a chamber connected to an intake port and an exhaust port, the intake port connected to a cleaning head of the mobile cleaning robot and the exhaust port connected to a blower of the mobile cleaning robot to generate an airstream through the cleaning head and through the chamber. ### Claim 16 (depends on 15) The mobile cleaning robot system of claim 15, wherein the chamber includes a first chamber and a second chamber separated by the filter, the first chamber configured to collect debris from the airstream. ### Claim 17 (depends on 16) The mobile cleaning robot system of claim 16, wherein the vacuum module includes a bottom door connected to the first chamber, the bottom door user-openable to empty debris from the first chamber. ### Claim 18 (depends on 16) The mobile cleaning robot system of claim 16, wherein the vacuum module includes an evacuation port configured to engage with a suction device of an evacuation station for evacuation of the first chamber by the evacuation station. ### Claim 19 A mobile cleaning robot system configured to clean a flooring surface of an environment, the mobile cleaning robot system comprising: a mobile cleaning robot comprising: a body including a cavity; and a drive system connected to the body and operable to move the mobile cleaning robot about the environment; a vacuum module including an extractor operable to extract debris from the environment when the vacuum module is installed in the cavity, the vacuum module user-securable to the cavity of the body; and a mop module including a cleaning pad configured to mop the flooring surface when the mop module is installed in the cavity, the mop module user-securable to the cavity of the body. ### Claim 20 (depends on 19) The mobile cleaning robot system of claim 19, wherein the vacuum module includes: a housing and a filter user-removable from the housing; a lid moveable to access the filter; and a chamber connected to an intake port and an exhaust port, the intake port connected to a cleaning head of the mobile cleaning robot and the exhaust port connected to a blower of the mobile cleaning robot to generate an airstream through the cleaning head and through the chamber, the chamber including a first chamber and a second chamber separated by the filter, the first chamber configured to collect debris from the airstream. ### Claim 21 (depends on 20) The mobile cleaning robot system of claim 20, wherein the body includes: a seating located between a front portion of the mobile cleaning robot and a rear portion of the mobile cleaning robot, the seating configured to receive the mop module to allow the mobile cleaning robot to perform mopping operations when the vacuum module is not installed and to receive the vacuum module to allow the mobile cleaning robot to perform vacuuming operations when the mop module is not installed;
