Abstract: Retrofit box systems to maximize operational capacity of inaccessible floors are described. The retrofit box system includes a gate complex that provides fluid communication between an inaccessible floor and a box, and a box to deliver a cleaner to the inaccessible floor and adapted for equalizing pressure when the inaccessible floor is under water while minimizing waste seepage from the retrofit box system. The retrofit box system further includes a power system and a control system to deliver the cleaner to the inaccessible floor and remove waste from the inaccessible floor and the box.

Abstract: Auger cleaned inaccessible floor systems to maximize operational capacity of inaccessible floors. The auger cleaned inaccessible floor system includes a floor having at least one channel beneath the lowest point of the floor extending horizontally at least half the length of the longest dimension of the floor and adapted for receiving an auger cleaner, at least one gate complex that provides fluid communication between the channel and at least one box and further provides access to the floor for the auger cleaner, and at least one box to deliver the auger cleaner to the channel and adapted for equalizing pressure when the inaccessible floor is under water to deliver an auger cleaner for cleaning. Thus, the auger cleaned inaccessible floor system allows cleaning of the inaccessible floor while the inaccessible floor system is in operation increasing the yield from the inaccessible floor system.
