Abstract
A floor cleaning device includes a base. A cleaning fluid supply tank is carried by the base. A source of pressure communicates with the cleaning fluid supply tank which pressurizes a cleaning fluid held in the cleaning fluid supply tank to an above atmospheric pressure. A fluid delivery system delivers pressurized cleaning fluid from the cleaning fluid supply tank to a surface to be cleaned.
Claims30
A floor cleaning device comprising:
- a base;
- a cleaning fluid supply tank carried by the base;
- a source of pressure communicating with the cleaning fluid supply tank which pressurizes a cleaning fluid held in the cleaning fluid supply tank to an above atmospheric pressure;
- and
- a fluid delivery system which delivers pressurized cleaning fluid from the cleaning fluid supply tank to a surface to be cleaned.

A method of cleaning a surface comprising:
- supplying a pressurized gas to a cleaning liquid supply tank;
- pressurizing a cleaning liquid held in the liquid supply tank;
- delivering the pressurized cleaning liquid to a distributor which applies the cleaning liquid to a surface to be cleaned;
- and,
- suctioning cleaning liquid from the floor into a recovery tank.
2 more elements
A carpet extractor comprising:
- a housing;
- a first cleaning liquid tank mounted to the housing;
- a fluid delivery system which delivers a cleaning liquid from the cleaning liquid tank to a surface to be cleaned;
- a heater which heats the cleaning liquid before it exits said fluid delivery system, the heater operating at a first power level in a warm-up phase and at a second power level, lower than the first power level, in an operational mode;
- a suction source carried by the housing, which functions only in the operational mode;
- and,
- a suction nozzle which fluidly communicates with the suction source, for withdrawing the cleaning liquid from the surface.
4 more elements
An extractor comprising:
- a housing;
- a cleaning fluid supply tank carried by the housing, for holding a cleaning fluid;
- a heater, carried by the housing, which heats the cleaning fluid;
- a fluid delivery system which delivers cleaning fluid from the cleaning fluid supply tank to a surface to be cleaned;
- a suction nozzle which withdraws dirty fluid from the surface;
- a suction source which fluidly communicates with the suction nozzle;
- and
- a control system which controls delivery of power to the suction source and the heater, the control system having a warm up mode, in which power is delivered at a first level to the heater and no power is delivered to the suction source, and an operational mode, in which power is delivered at a second, lower, level to the heater, and power is delivered to the suction source.
