Water trailing detection system
First Claim
1. A floor cleaning machine comprising:
- a chassis configured to move along a cleaning path;
a cleaning mechanism connected to the chassis to perform a cleaning operation;
a liquid system connected to the chassis to provide liquid to the cleaning mechanism;
a recovery system connected to the chassis to recover liquid from the cleaning operation;
a control system connected to the floor cleaning machine to control performance of the cleaning operation; and
a cleaning operation sensing system connected to the control system and including a moisture sensor configured to detect moisture from the cleaning operation, the moisture sensor comprising a first conductive bristle defining a first electrode that is spaced from a second conductive bristle defining a second electrode, wherein the first and second electrodes are disposed in close proximity to the cleaning path and are configured to sense the liquid from the cleaning operation external to the floor cleaning machine.

Abstract
A floor cleaning machine can comprise a chassis, a cleaning mechanism, a control system, and a cleaning operation sensing system connected to the chassis. The chassis can be configured for movement along a cleaning path. The cleaning mechanism can perform a cleaning operation. The liquid system can provide liquid to the cleaning mechanism. The recovery system can recover liquid from the cleaning operation. The control system can control performance of the cleaning operation. The cleaning operation sensing system can detect a condition of the cleaning operation. The cleaning operation sensing system can comprise a water trailing detection system comprising: a frame connected to the chassis aft of the recovery system, an absorbent medium connected to the frame; and a moisture sensor in communication with the control system to alter a signal in response to moisture in the absorbent medium.
