1. A surface cleaning apparatus, comprising:
- a) a body having a forward compartment and rear compartment, wherein the forward compartment includes a wall;
b) an elongate rotatable brush extending across the forward compartment and positioned to propel debris up the wall;
c) an electric motor in the rear compartment;
d) a belt connecting the motor and rotatable brush; and
e) a cleaning strip assembly pivotably mounted on an underside of the body, the cleaning strip assembly comprising an elongate support member housed within an underside of the wall, a flexible strip extending along substantially the entire length of the elongate support member, and a plurality of tabs for engaging a surface being cleaned, the engagement of the plurality of tabs with the surface being capable of causing the cleaning strip assembly to pivot between a cleaning position and an elevated position.

16. A surface cleaning apparatus comprising:
-
a housing; an elongate brush arrangement mounted so as to be rotatable about a longitudinal axis thereof, extending across the housing for contacting a surface to be cleaned, and positioned to propel debris up a wall within the housing; a substantially continuous surface cleaning strip extending across an underside of the housing; movement responsive means including friction engaging means adapted to engage the surface to be cleaned and movable in opposing first and second directions in response to movement of the apparatus in opposing first and second directions relative to the surface to be cleaned, movement of the friction engaging means being transmitted to the cleaning strip; and movement stop means adapted to allow the cleaning strip to adopt a first orientation, a second orientation, and orientations between the first orientation and second orientation, and to prevent the cleaning strip from adopting orientations beyond the first orientation or second orientation, wherein the cleaning strip and the friction engaging means are mounted on an elongate member which is pivotably mounted within an underside of the wall, whereby contact between the friction engaging means and the surface to be cleaned causes the elongate member to pivot such that the cleaning strip adopts one of the first and second orientations. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)

36. A surface cleaning apparatus comprising:
-
a housing; an elongate rotatable brush arrangement extending across the housing and positioned to propel debris up a wall within the housing; an elongate support member housed in a cavity in an underside of the wall; a substantially continuous surface cleaning strip extending across an underside of the housing, the surface cleaning strip being mounted on the elongate support member, the elongate support member being rotatable between a cleaning orientation where the surface cleaning strip contacts a surface to be cleaned, and a second orientation where the surface cleaning strip is raised clear of the surface to be cleaned; and at least one surface engagement structure mounted on the elongate support member in an orientation relative to the surface cleaning strip such that in the cleaning orientation the surface engagement structure contacts a wall of the cavity, and in the second orientation the surface engagement structure contacts the surface to be cleaned; wherein movement of the surface engagement structure in a cleaning direction causes the cleaning strip to adopt the cleaning orientation and wherein movement of the surface engagement structure in a direction opposite to the cleaning direction causes the cleaning strip to adopt the second orientation. - View Dependent Claims (37, 38, 39, 40, 41)

42. A surface cleaning apparatus, comprising:
-
a body having a forward compartment and rear compartment, wherein the forward compartment includes a rear wall; an elongate rotatable brush extending across the forward compartment and positioned to propel debris up the wall; a belt connecting an electric motor to the rotatable brush; and a cleaning strip assembly pivotably mounted on an underside of the body, the cleaning strip assembly comprising an elongate support member housed within an underside of the wall, a flexible strip extending along substantially the entire length of the elongate support member, and a plurality of tabs for engaging a surface being cleaned, the engagement of the plurality of tabs with the surface being capable of causing the cleaning strip assembly to pivot between a cleaning position and an elevated position. - View Dependent Claims (43, 44, 45, 46, 47, 48, 49)
