The skilled addressee will appreciate that the application of water and cleaning mixture onto an object to be cleaned using the cleaning device 100 set in the water and cleaning mixture dispensing mode wherein water and cleaning mixture is dispensed from the cleaning device 100 is usually followed by a scrubbing motion of the brush 104 of the cleaning device 100 onto the object to be cleaned. As such, the stream of water and cleaning mixture exiting the cleaning device 100 does not need to travel a distance before reaching the object to be cleaned, hence the flow rate being lower in the water and cleaning mixture dispensing mode than in the water dispensing mode and the second water dispensing mode.

In a preferred embodiment, when the cleaning device 100 is set to the water and cleaning mixture dispensing mode, water and cleaning mixture are dispensed from the cleaning device 100 at a flow rate of 1 L/min.

In the water dispensing mode, water is dispensed from the cleaning device 100 with an amount of force sufficient to effectively rinse off cleaning mixture previously applied on an object to be cleaned. The flow rate provided in such mode is thus higher than in the water and cleaning mixture dispensing mode.

Still in a preferred embodiment, when the cleaning device 100 is set to the water dispensing mode, water is dispensed from the cleaning device 100 at a flow rate of 2L/min.

In the second dispensing mode, water is dispensed from the cleaning device 100 with an amount of force sufficient to clean off debris from an object to be cleaned. The flow rate provided in such mode is thus higher than in the water and cleaning mixture dispensing mode and in the water dispensing mode.

Still in a preferred embodiment, when the cleaning device 100 is set to the second water dispensing mode, water is dispensed from the cleaning device 100 at a flow rate of 3L/min. DM_MTL/274566-00004/l 750692.8

- 28 -

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 12L/min as provided by a standard garden hose tap known to the skilled addressee, may consume about 144L of water. The cleaning of a car using a cleaning device 100 according to one embodiment of the present invention may consume about 28L 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.
