TINECO FLOOR ONE S7 PRO Pro Self Cleaning Loop

Dirty Water Tank Assembly

The Dirty Water Tank contains silver-plated electrodes that measure the conductivity and volume of the waste fluid. If these sensors are fouled by detergent buildup or mineral deposits, they provide a false 'dirty' or 'full' signal to the control board. This prevents the machine from verifying that the self-cleaning cycle was successful, causing the firmware to immediately re-trigger the sequence.

iLoop Smart Sensor Assembly

The iLoop sensor is an infrared-based optical assembly located in the vacuum's throat that detects debris density. If the internal IR emitter or receiver is obscured by residue or if the plastic housing is scratched, the sensor enters a 'fixed high' state. The system interprets this as a persistent clog or heavy soil, looping the self-cleaning mode in a failed attempt to clear the optical path.

Charging Dock Base Station

The base station contains the logic interface that initiates the 'Pro' cleaning sequence and manages power delivery for the electrolysis process. Internal corrosion or moisture on the dock's PCB can cause a 'stuck' logic state where the cleaning command is pulsed continuously via the communication pins on the vacuum's rear interface.
