Floor maintenance machine
First Claim
1. A method of maintaining a floor by applying fluid thereto, said method comprising:
- discharging a diluting fluid from a first reservoir to a mixing apparatus, the first reservoir being a gravity-feed reservoir;
discharging a cleaner concentrate from a second reservoir to the mixing apparatus with a selectively on pump;
mixing the discharged diluting fluid and cleaner concentrate to form a cleaning solution;
continuously identifying changes in fluid levels within the first reservoir with a level sensor;
providing a first signal indicative of an identified change in fluid level in the first reservoir;
passing the cleaner concentrate and diluting fluid through a flow control device for discharge therefrom;
andprocessing the first signal to generate an output signal and controlling operation of the pump and the flow control device in response to the output signal to provide a uniform flow of fluid to a cleaning device at a substantially constant ratio of the diluting fluid from the first reservoir to the cleaner concentrate from the second reservoir for substantially all fluid levels of the first reservoir.
