A tipping method for a tipping arrangement which includes a first element (1) and a second element (2), arranged between a moveable base unit (4) and a rotatable container (3). The container (3) is rotated by moving the second element (2) along a first track (7) on the first element (1). The second element (2) is moved along the track (7) by rotating the second element (2) relative to the first element (1). A number of engaging parts (9, 10) may be arranged on the tracks (7, 8) of the elements (1, 2), respectively. An interlocking arrangement may be arranged between the first element (1) and the second element (2) to secure the second element (2) in a starting position. A movable unit includes the tipping arrangement and a section unit, with the container (3) locked in a vertical position by a locking arrangement.

1. A movable vacuum cleaning unit for cleaning up one or more of liquids, fluids, debris and particles, said movable cleaning unit comprising: a movable base unit and a rotatable container having a container bottom, at least one container sidewall, and a container inlet for a suction hose through which container inlet the one or more of liquids, fluids, debris and particles are transferred to become contents of the rotatable container, the rotatable container having a center of gravity inside the rotatable container at a certain height above the container bottom;a tipping arrangement configured for connection to the movable base unit and to the rotatable container such that the rotatable container is manually rotatable around the tipping arrangement so that when emptying the contents of the container during a manual emptying rotation of the rotatable container from a substantially vertical, first position on the movable base unit to a substantially horizontal second position on the movable base unit a combined center of gravity of the rotatable container and the contents of the rotatable container shifts as a combined mass of the rotatable container and the contents of the rotatable container is reduced,the at least one container sidewall having a pouring lip on an upper part thereof,the tipping arrangement having a first element comprising a first track configured to contact a second track on a second element of the tipping arrangement in a contact area between the first track and the second track that moves during the manual emptying rotation of the rotatable container starting from the first position with the first element and the second element connected at a vertical height from the bottom of the container substantially corresponding to the height of the center of gravity of the rotatable container in the first position, the second element being movable from the first position of the rotatable container along the first track during the manual emptying rotation to the second position of the rotatable container as the contact area between the first track and the second track comprising a pivot point is shifted towards the combined center of gravity of the rotatable container and the contents of the rotatable container as the combined center of gravity shifts during the manual emptying rotation ending with the upper part of the container sidewall including the pouring lip oriented substantially vertically in the second position, the second element being rotatable relative to the first element such that the second element is movable along the first track for allowing the container to rotate in a direction opposite the manual emptying rotation starting from the second position to the first position in which the upper part of the container sidewall including the pouring lip is oriented substantially horizontally with the rotatable container in the substantially vertical, first position on the movable base unit. 2. The movable vacuum cleaning unit according to claim 1, wherein the second element includes a stabilizing flap. 3. The movable vacuum cleaning unit according to claim 2, wherein the second element is angled relative to the first element, the contact area between the two tracks being moved along the first track during rotation of the second element. 4. The movable vacuum cleaning unit according to claim 1, wherein a shape of the second track is determined according to a number of positions of the center of gravity of the rotatable container and the contents of the rotatable container during the rotation of the rotatable container. 5. The movable vacuum cleaning unit according to claim 4, wherein one or both of the first track and the second track has or have at least one of a planar surface, a curved surface and a wave shaped surface having a crest and a trough. 6. The movable vacuum cleaning unit according to claim 1, wherein the tipping arrangement further comprises an interlocking arrangement configured to hold the second element to the first element when the second element is in the first position. 7. The movable vacuum cleaning unit according to claim 1, wherein the base unit comprises a steering arrangement for manually moving the vacuum cleaning unit. 8. The movable vacuum cleaning unit according to claim 1, wherein a number of engaging female and male parts are arranged on the first track and on the second track respectively. 9. A movable vacuum cleaning unit comprising: a movable base unit;a rotatable container positioned on the base unit having a container inlet for a suction hose through which container inlet vacuumed contents are transferred in a substantially vertical, first position of the rotatable container; and,a tipping arrangement arranged between the base unit and the rotatable container, the tipping arrangement configured for connection to the base unit and to the rotatable container at a vertical height from a bottom of the rotatable container substantially corresponding to a center of gravity of the rotatable container in the first position, such that the rotatable container is manually rotatable around the tipping arrangement, the rotatable container having a pouring lip on an upper part of a sidewall thereof, the tipping arrangement having a first element configured as a track element, a second element configured to move along the first element, the first element having a first track including a number of engaging male or female parts configured to contact a second track of the second element, the second track including a number of respective engaging female or male parts, the second element being rotatable relative to the first element, such that the second element is movable along the first track for allowing the container to rotate from the first position in which the part of the sidewall including the pouring lip is substantially horizontal to a second position in which the part of the sidewall including the pouring lip is substantially vertical, the second element being movable along the first track during manual rotation of the container to the second position such that when emptying the vacuumed contents of the rotatable container during an emptying rotation of the rotatable container from the first position to the second position a combined center of gravity of the rotatable container and the vacuumed contents of the rotatable container shifts as a combined mass of the rotatable container and the vacuumed contents of the rotatable container is reduced during the emptying. 10.
