A mobile cleaning robot can include a body, a pad assembly, and a pad drive system. The pad assembly can be connected to the body and can be movable relative thereto. The pad drive system can be connected to the body and can be operable to move the pad assembly relative to the body between a stored position and a cleaning position.

Two in one mobile cleaning robot

A cleaning pad for a mobile cleaning robot can include a backing layer, a cleaning layer, and a card. The backing layer can be user-releasably securable to a pad tray of the mobile cleaning robot. The cleaning layer can be affixed to the backing layer and engageable with a floor surface. The card can be connected to at least one of the backing layer and the cleaning layer and can be engaged with the backing layer. The card can be slidably insertable into a retainer of the pad tray to align the cleaning pad with the pad tray of the mobile cleaning robot.

Cleaning pad assembly for mobile robot

A mobile robot includes a body configured to traverse a surface and to receive debris from the surface, and a debris bin within the body. The debris bin includes a chamber to hold the debris received by the mobile robot, an exhaust port through which the debris exits the debris bin; and a door unit over the exhaust port. The door unit includes a flap configured to move, in response to air pressure at the exhaust port, between a closed position to cover the exhaust port and an open position to open a path between the chamber and the exhaust port. The door unit, including the flap in the open position and in the closed position, is within an exterior surface of the mobile robot.

Evacuation station

An autonomous coverage robot includes a cleaning assembly having forward roller and rearward rollers counter-rotating with respect to each other. The rollers are arranged to substantially maintain a cross sectional area between the two rollers yet permitting collapsing therebetween as large debris is passed. Each roller includes a resilient elastomer outer tube and a partially air-occupied inner resilient core configured to bias the outer tube to rebound. The core includes a hub and resilient spokes extending between the inner surface of the outer tube and the hub. The spokes suspend the outer tube to float about the hub and transfer torque from the hub to the outer tube while allowing the outer tube to momentarily deform or move offset from the hub during impact with debris larger than the cross sectional area between the two rollers.

Robotic vacuum cleaning system

A mobile cleaning robot can include a body, a drive wheel, and a wheel stop. The drive wheel can be connected to the body and can be operable to move the mobile cleaning robot about an environment. The wheel stop can be movable with respect to the body and the drive wheel between a stop position and a release position. The wheel stop can be engageable with the drive wheel in the stop position to limit vertical travel of the drive wheel with respect to the body.

Mobile cleaning robot with adjustable suspension

A robot floor cleaning system features a mobile floor cleaning robot and an evacuation station. The robot includes: a chassis with at least one drive wheel operable to propel the robot across a floor surface; a cleaning bin disposed within the robot and arranged to receive debris ingested by the robot during cleaning; and a robot vacuum configured to pull debris into the cleaning bin from an opening on an underside of the robot. The evacuation station is configured to evacuate debris from the cleaning bin of the robot, and includes: a housing defining a platform arranged to receive the cleaning robot in a position in which the opening on the underside of the robot aligns with a suction opening defined in the platform; and an evacuation vacuum in fluid communication with the suction opening and operable to draw air into the evacuation station housing through the suction opening.

Debris evacuation for cleaning robots

An evacuation station includes a base and a canister removably attached to the base. The base includes a ramp having an inclined surface for receiving a robotic cleaner having a debris bin. The ramp defines an evacuation intake opening arranged to pneumatically interface with the debris bin. The base also includes a first conduit portion pneumatically connected to the evacuation intake opening, an air mover having an inlet and an exhaust, and a particle filter pneumatically the exhaust of the air mover. The canister includes a second conduit portion arranged to pneumatically interface with the first conduit portion to form a pneumatic debris intake conduit, an exhaust conduit arranged to pneumatically connect to the inlet of the air mover when the canister is attached to the base, and a separator in pneumatic communication with the second conduit portion.

This document describes a mobile cleaning robot including a chassis having a forward portion and an aft portion; a blower affixed to the chassis; a bin supported by the chassis and configured to receive airflow from the blower, the chassis enabling evacuation of the bin through a bottom of the robot. The bin includes a top, a bottom, a sidewall, and an internal barrier. The bin includes a first volume and a second volume separated by the internal barrier and a filter unit supported by the internal barrier and removably disposed in an airflow path between the first volume that includes an intake port in the bin and the second volume that includes an exhaust port in the bin.
