Cleaner apparatus

A cleaner apparatus for spraying a cleaning composition, the cleaner apparatus comprising:

• an apparatus housing at least partially defining an interior of the cleaner apparatus;
• a spray outlet assembly extending from the apparatus housing to an exterior of the apparatus housing, the spray outlet assembly configured to be directly exposed to an interior of a separate device;
• a pump device configured to pump an amount of the cleaning composition through the spray outlet assembly such that the spray outlet assembly is configured to spray the amount of the cleaning composition as a fluid stream;
• a controller configured to operate the pump device to cause the amount of the cleaning composition to be pumped through the spray outlet assembly without manual intervention;
• and
• a structure connector that is configured to connect the cleaner apparatus to an external structure to at least partially hold the cleaner apparatus in place in relation to an opening in a housing of the separate device, such that
• the apparatus housing of the cleaner apparatus is external to the separate device, and
• the spray outlet assembly is at least partially inserted into the interior of the separate device through the opening in the housing of the separate device, such that the spray outlet assembly extends from the apparatus housing external to the separate device and through the opening in the housing of the separate device to the interior of the separate device.
