## Abstract

A surface cleaner has a surface cleaning head having a separated material collection region which, in operation to clean a floor, receives solid and liquids. A rigid up flow conduit is moveable mounted to the surface cleaning head between an upright storage position and a reclined operating position. A hand vacuum cleaner has a first cleaning stage, a downstream second cleaning stage and a motor and fan assembly positioned in the air flow path. The first cleaning stage comprises a non-cyclonic momentum separator. The hand vacuum cleaner is removably mountable to the upper end of the up flow conduit. The hand vacuum cleaner dirty air inlet is removably mountable to the upper end of the up flow conduit and, when the hand vacuum cleaner is mounted to the upper end of the up flow conduit, the hand vacuum cleaner is supported by the up flow conduit.

## Claims

### Claim at position 1

1-20. (canceled)

### Claim 21

A surface cleaner comprising:
a surface cleaning head having a spray nozzle and a separated material collection compartment, the separated material collection compartment comprises a solid collection sub-compartment and a liquid collection sub-compartment, the separated material collection sub-compartment comprises a porous interface which physically separates the solid collection sub-compartment and the liquid collection sub-compartment, wherein, when the surface cleaning head is positioned on a floor to clean the floor, the porous interface is provided at a lower end of the solid collection sub-compartment and the solid collection sub-compartment is positioned above the liquid collection sub-compartment;
a rigid rod moveably mounted to the surface cleaning head between an upright storage position and a reclined operating position,
wherein, in operation to clean a surface in which liquid and solid material is drawn into the surface cleaning head, solid material is collected in the solid collection sub-compartment, liquid is collected in the liquid collection sub-compartment.

### Claim 22 (depends on 21)

The surface cleaner of claim 21 wherein, when the surface cleaning head is positioned on a floor to clean the floor, the solid collection region overlies the liquid collection region.

### Claim 23 (depends on 21)

The surface cleaner of claim 21 wherein the liquid collection region and the solid collection region are emptiable separately.

### Claim 24 (depends on 21)

The surface cleaner of claim 21 wherein the rigid rod is an up flow conduit which, in the storage position, has a lower air inlet and an upper air outlet, the surface cleaner further comprises a hand vacuum cleaner that is removably mountable to the upper end of the up flow conduit, the hand vacuum cleaner has an air flow path from a hand vacuum cleaner dirty air inlet to a clean air outlet with an air treatment chamber and a motor and fan assembly positioned in the air flow path, wherein, when the hand vacuum cleaner is mounted to the upper end of the up flow conduit, the hand vacuum cleaner dirty air inlet is in fluid flow communication with the upper air outlet of the up flow conduit.

### Claim 25 (depends on 24)

The surface cleaner of claim 24 wherein the hand vacuum cleaner dirty air inlet is removably mountable to the upper end of the up flow conduit.

### Claim 26 (depends on 24)

The upright surface cleaner of claim 24 wherein the up flow conduit is a wand, which is a sole support structure that connects the hand vacuum cleaner with the surface cleaning head.

### Claim 27 (depends on 23)

The upright surface cleaner of claim 23 wherein the spray nozzle is directed at a rotatably mounted brush in the surface cleaning head.

### Claim 28 (depends on 21)

The surface cleaner of claim 21 further comprising an on board energy store.

### Claim 29

A surface cleaner comprising:
a surface cleaning head having a solid collection region and a liquid collection region wherein, in operation to clean a surface during which liquid and solid material are drawn into the surface cleaning head, solid material is collected in the solid collection region and liquid is collected in the liquid collection region, and wherein the liquid collection region and the solid collection region are emptiable separately;
a rigid rod moveably mounted to the surface cleaning head and positionable in an upright storage position and a reclined operating position.

### Claim 30 (depends on 29)

The surface cleaner of claim 29 wherein, when the surface cleaning head is positioned on a floor to clean the floor, the solid collection region is positioned above the liquid collection region.

### Claim 31 (depends on 30)

The surface cleaner of claim 30 wherein the separated material collection region further comprises a porous interface which separates the solid collection region and the liquid collection region.

### Claim 32 (depends on 31)

The surface cleaner of claim 31 wherein the porous interface is provided at a lower end of the solid collection region.

### Claim 33 (depends on 32)

The surface cleaner of claim 32 wherein, when the surface cleaning head is positioned on a floor to clean the floor, the solid collection region overlies the liquid collection region.

### Claim 34 (depends on 29)

The surface cleaner of claim 29 wherein the surface cleaning head further comprises a rotatably mounted brush at a front end of the surface cleaning head and, when the surface cleaning head is positioned on a floor to clean the floor, the liquid collection region has a rear end that is rearward of the solid collection region.

### Claim 35 (depends on 34)

The surface cleaner of claim 34 wherein the surface cleaning head further comprises a first rotatably mounted brush at a front end of the surface cleaning head and a second rotatably mounted brush positioned rearward of the first rotatably mounted brush.

### Claim 36 (depends on 34)

The surface cleaner of claim 34 further comprising an on board energy store.

### Claim 37 (depends on 29)

The surface cleaner of claim 29 wherein the surface cleaning head further comprises a first rotatably mounted brush at a front end of the surface cleaning head and a second rotatably mounted brush positioned rearward of the first rotatably mounted brush.

### Claim 38 (depends on 29)

The surface cleaner of claim 29 further comprising an on board energy store.

### Claim 39 (depends on 29)

The surface cleaner of claim 29 wherein the surface cleaning head further comprises a spray nozzle.

### Claim 40 (depends on 39)

The surface cleaner of claim 39 wherein the spray nozzle is directed at a rotatably mounted brush in the surface cleaning head.
