An autonomous mobile robot includes a body, a drive supporting the body above a floor surface, a light-propagating plate positioned on the body and having a periphery defining a continuous loop, light sources each being positioned to direct light through a portion of the plate to a portion of the continuous loop, and a controller to selectively operate the light sources to provide a visual indicator of a status or service condition of the autonomous mobile robot. The drive is configured to maneuver the mobile robot about the floor surface.

An environmental control unit comprises a housing, a vacuum cleaner, a filtration unit, and a blower. The vacuum cleaner is positioned in the housing and is configured to receive a tool contaminant stream produced by at least one tool. The vacuum cleaner filters particulate matter from the tool contaminant stream, thereby producing a filtered air stream. The filtration unit is also positioned within the housing and comprises at least one filter. The blower is positioned within the housing downstream of the filtration unit. The blower is configured to create negative air pressure within the second compartment to draw an area contaminant stream from an exterior of the environmental control unit into the housing. A second blower may also be present. The blower draws the filtered air stream and the area contaminant stream through the at least one filter in the filtration unit to produce a filtered mixture stream.

A detection system for detecting a virus or the like. The detection system includes an autonomous collection device that is capable of moving on a floor surface and for collecting an object on the floor surface, and a station device for detecting an analyte from the object collected from the floor surface by the autonomous collection device. The autonomous collection device includes a moving part for moving on the floor surface, a primary electric blower for sucking the object on the floor surface, and a dust container for storing the sucked object. The station device includes a transfer pipe fluidically connected to the dust container of the autonomous collection device when the autonomous collection device is positioned in a home position, and a virus detection part for detecting the analyte from the object transferred from the dust container through the transfer pipe.

The present invention discloses a self-moving robot, comprising a self-moving module and at least one of a plurality of interchangeable working modules connected to the self-moving module; the working module further comprises a second energy unit, and the first energy unit comprises a chargeable battery, providing energy for the working module or the self-moving robot. The self-moving robot executes various types of working tasks in the working area in an unattended manner by disposing a self-moving module and an interchangeable working module, and by disposing the working module into an independent energy unit, the working module is sufficient in energy and long in durability.

The present disclosure concerns a system comprising an evaluation unit and a sensor, wherein the sensor can measure a vital parameter of an organism and the evaluation unit allows to conduct an evaluation based on the measured vital parameter. The evaluation unit is configured such that the evaluation unit can send a command signal to an external device, particularly to a household appliance, in dependency of a result of the evaluation, so that the external device carries out an action based on the command signal. The present disclosure also concerns a use, a method and a computer program product. The user can thereby save time and a very high operating comfort can be realized.

A hand vacuum cleaner has a suction motor and fan assembly having a suction motor axis of rotation, an air treatment member having an openable door and a central longitudinal axis extending between the front and rear ends of the air treatment member; and, a handle having a having a hand grip portion wherein the hand grip portion extends upwardly and forwardly when the hand vacuum cleaner is oriented with the upper end of the hand vacuum cleaner above the lower end of the hand vacuum cleaner. The central longitudinal axis intersects the openable door and the hand grip portion.

A feces collection device for sanitary collection and disposal of fecal matter includes a housing that defines an internal space. An orifice is positioned in a front of the housing. A first grate is positioned in the housing proximate to a back of the housing. A power module and a motor are coupled to the housing and positioned in the internal space. The motor is selectively operationally couplable to the power module. A fan is coupled to the motor and is positioned in the internal space. The motor is positioned to rotate the fan. The fan is configured to pull air and the fecal matter through the orifice into the internal space. The fecal matter is retained in the internal space as the air exits the internal space through the first grate.

A vacuum tool configured to be removably coupled to hose or wand of a vacuum includes a body including a first end, a second end, and a first longitudinal axis extending between the first end and the second end. The vacuum tool also includes a head coupled to the first end of the body, a connection portion coupled to the second end of the body and configured to couple the body to a hose or wand of a vacuum cleaner, and a brush coupled to the head. The brush includes an elongate support defining a second axis perpendicular to the longitudinal axis of the body and configured to couple the brush to the head, and a plurality of bristles positioned on the elongate support.

A hand vacuum cleaner has a cyclone having a cyclone axis of rotation that extends between the front and rear ends of the cyclone. A main body houses a suction motor. The suction motor is positioned at a lower end of the main body and forward of a battery pack provided at a lower end of a pistol grip handle.

Devices for collecting patient excretions utilize existing suction sources and facilitate the cleaning of bedding and/or a patient. Patient excretion collection devices comprise a collection reservoir and a collection wand which are attached to an existing source of suction.
