## Abstract

The present invention relates to an improved grout tool generally employed with a multi-functional surface cleaning machine having a fluid tank, a pump, and at least one receptacle for holding concentrated cleaning chemicals. In one embodiment, the grout tool employs fluid jets, adjustably connected via brackets, such that the jets are positioned at an angle relative to the grout tool body to allow fluid to hit a surface of an angle.

## Claims

### Claim 1

A grout tool for use with a portable surface cleaning device, comprising:
a tool body having a front, a back, a base and a top;
one or more brushes having a proximate and a distal end, the proximate end of the one or more brushes being removably attached to the back of the tool body and the one or more brushes extending below the base of the tool body;
at least two brackets adjustably connected to the top of the tool body, wherein each bracket includes a first surface which is positioned substantially over the top of the tool and second surface which projects beyond the top of the tool body and which is angled toward the tool base; and
at least one fluid jet connected to the second surface of each of the brackets.

### Claim 2 (depends on 1)

The device of claim 1, wherein the fluid jets are positioned by the brackets to spray fluid beyond the distal end of the one or more brushes.

### Claim 3 (depends on 1)

The device of claim 1, wherein the fluid jets are positioned by the brackets to spray fluid at the distal end of the one or more brushes.

### Claim 4 (depends on 1)

The device of claim 1, wherein the fluid jets are positioned by the brackets to spray fluid into the one or more brushes.

### Claim 5 (depends on 1)

The device of claim 1, further comprising at least one hose connected to each fluid jet wherein each hose is in fluidic communication with a quick disconnect coupling device.

### Claim 6 (depends on 1)

The device of claim 1, further comprising a vacuum chamber defined by a first squeegee and a second squeegee positioned adjacent to a front edge of the tool body and a second edge of the tool body respectively.

### Claim 7 (depends on 1)

The device of claim 1, further comprising a vacuum inlet in operative association with the vacuum chamber and adapted for connection to a suction device.

### Claim 8 (depends on 1)

The device of claim 1, further comprising a plurality of squeegees connected to the tool body and adapted for contact with the surface.
