The skilled addressee will appreciate that the flow rates provided are merely suggestions and may be different, given that the rank of flow rate of each mode relatively to the other modes is respected.
The skilled addressee will thus appreciate that the above-described invention is of great advantage since the switch assembly 108 provides the cleaning device 100 with water saving abilities by enabling a user to select a flow rate based on an amount of water needed for a cleaning operation.
For instance, the cleaning of a car using a cleaning device 100 according to one embodiment of the prior art, using a constant flow of water at a flow rate of about 12 L/min as provided by a standard garden hose tap known to the skilled addressee, may consume about 144 L of water. The cleaning of a car using a cleaning device 100 according to one embodiment of the present invention may consume about 28 L of water, providing a saving of about 81% of the total amount of water used in the process.
The switch assembly 108 further enables a user to selectively use for a cleaning operation water with cleaning mixture or water without cleaning mixture, for a rinsing phase of a cleaning operation for instance. The present invention further offers to a user a notable advantage over prior art by eliminating the need to successively plug and unplug multiple device to and from the water hose to dispense water from the cleaning device 100 at different flow rates.
Although the above description relates to a specific preferred embodiment as presently contemplated by the inventor, it will be understood that the invention in its broad aspect includes mechanical and functional equivalents of the elements described herein.
