Automated cleaning device

A pool debris collection system comprising:

• an automated cleaning device submersible in pool water comprising a device body, at least one filter cassette releasably mounted within the device body, the at least one filter cassette having a debris container and a flotation device, a cartridge mounted to the device body configured to release a gas into the flotation device of one of the at least one filter cassettes to inflate the flotation device, the automated cleaning device being configured to selectively release the at least one filter cassette into the pool water, the at least one filter cassette having a transmitter for releasing a signal upon reaching the top of the water;
• a receiver attached to a pool skimmer for activating a pool skimmer pump in response to the signal from the at least one filter cassette;
• and
• a sensor attached to the pool skimmer for detecting that the at least one filter cassette has reached the pool skimmer and sending an alert in response to the detection.

A computer implemented method for automatically cleaning a pool comprising:

• submersing a device body configured to move along the bottom of a pool into a pool, the device body having a filter canister mounted within the device body, a plurality of filter cassettes releasably mounted within the filter canister, each filter cassette having a filter container and a flotation device;
• activating a vacuum pump on the device body to collect debris on the bottom of the pool into the filter container of a first one of the filter cassettes;
• automatically activating a cartridge mounted to the device body to release a gas into a flotation device of the first filter cassette to inflate the flotation device in response to filter container being full;
• and;
• automatically releasing the first filter cassette from the filter canister upon inflation of the flotation device.
