The flexible cleaning apparatus has a cleaning fluid interface configured to provide cleaning solution to the plurality of extendible tubes. The flexible cleaning apparatus has a plurality of nozzles disposed along the plurality of extendible tubes and is configured to transit the cleaning solution from the plurality of extendible tubes to the internal cleaning region. The plurality of extendible tubes are each configured to adjust between a first length and a second length to adjust a volume of the internal cleaning region.
