A cleaner includes a body, a left spin-mop module located on a left side of the body and a right spin-mop module located on a right side of the body, each of the left spin-mop module and the right spin-mop module being rotatable about a first rotational axis to perform mopping, a left spin-drive unit disposed on the left side of the body, the left spin-drive unit being configured to provide a force to rotate the left spin-mop module; and a right spin-drive unit disposed on the right side of the body, the right spin-drive unit being configured to provide a force to rotate the right spin-mop module. Each of the left spin-drive unit and the right spin-drive unit has a second rotational axis that extend in a direction different from the first rotational axis of the respective left spin-drive unit and the right spin-drive unit.

A surface maintenance machine includes a maintenance head assembly comprising one or more surface maintenance tools for performing a surface maintenance operation. The machine also includes wheels and an operator grab handle permitting the operator to apply a force to urge the machine to change orientation. The machine also includes a first and second motor controlled by a motor controller. The motor controller is configured to sense a parameter indicative of motor load on the first and second motor and control the power delivered to the first and second motor to maintain a torque output setting. Maintaining the torque output setting is in light of motor load on the first and second motor and the force applied to the machine by the operator. The control of power delivered to the motors to maintain the torque assists the force applied by the operator to the machine.

A cleaner includes a first cleaning module including a left spin mop and a right spin mop that come into contact with a floor while rotating in a clockwise direction or in a counterclockwise direction when viewed from an upper side, a second cleaning module that comes into contact with the floor at a position spaced apart from the left spin mop and the right spin mop in a forward-and-backward direction, a body supported by the first cleaning module and the second cleaning module, and a water supply module that supplies water to the first cleaning module. A water tank is disposed inside the body. Water supplied by the water supply module reaches the first cleaning module before reaching the floor.

A floor cleaning machine having a machine housing, cleaning-liquid and dirty-liquid tanks received in the machine housing, a chassis with front and rear wheels spaced apart along a longitudinal axis and facilitating movement of the machine housing over a floor surface, a cleaning device configured to clean the floor surface, a cleaning liquid applicator that dispenses a cleaning liquid from the cleaning-liquid tank to a region of the cleaning device, and a dirty-liquid intake that is in fluid communication with the dirty-liquid tank and configured to intake liquid on the floor surface and discharge the liquid to the dirty-liquid tank. The dirty-liquid intake being disposed on the machine housing behind the rear wheel and being movable relative to the machine housing between a retracted position and an extended position. The dirty liquid intake is closer to the rear wheel when disposed in the retracted position.

Provided herein are systems, methods and devices for classifying nested content execution loaded by a webpage or an application executed by a client device, comprising a client device executing a webpage or an application loaded from a content server which embed nesting element(s) used for loading nested content from nested content server(s). The webpage/application embeds a host monitoring code executed to collect session data indicative of execution session of the webpage/application including execution of nested content loaded using the nesting element(s), transmitting a signature of the session data to server(s) configured to classify the execution according to at least part of the session data extracted from the signature, and transmitting transaction indicator(s) of execution of the nested content to one or more providers of the nested content which may verify execution of the nested content in the context of the webpage/application based on the classification obtained from the server(s).
