The present invention refers to a cleaning trolley comprising a base plate supported by rolling members; at least four upright hollow profiles for fixing cross walls arranged on the base plate, wherein each cross wall consists of two separate wall elements removably arranged back-to-back to each other and fixed by said upright hollow profiles; and an upper frame for securing the at least four upright hollow profiles. Further, the invention provides a cleaning trolley comprising a primary section and a secondary section, each section having a base plate supported by rolling members, wherein the primary section and the secondary section are removably connected by a connection mechanism, which connection mechanism contains a pedal pivotably attached to the bottom side of the base plate of the secondary section, and its actuation releases claws which in connection position are engaged with the primary section.

1. A cleaning trolley, comprising: A. a first modular unit, comprising: (i) a first base plate;(ii) at least four first upright hollow profiles for fixing first cross walls arranged on the first base plate, each of the four first upright hollow profiles including at least one groove,wherein each first cross wall consists of two first wall elements removably arranged back-to-back to each other to form two first opposed edges, each first opposed edge defined by an area with reduced thickness and a terminal beaded edge shaped to be fixably inserted into the groove of one of the four first upright hollow profiles; and(iii) a first upper frame for securing the at least four first upright hollow profiles, B. a second modular unit, comprising: (i) a second base plate;(ii) at least four second upright hollow profiles for fixing second cross walls arranged on the second base plate, each of the four second upright hollow profiles including at least one groove, wherein each second cross wall consists of two second wall elements removably arranged back-to-back to each other to form two second opposed edges, each second opposed edge defined by an area with reduced thickness and a terminal beaded edge shaped to be fixably inserted into the groove of one of the four second upright hollow profiles; and(iii) a second upper frame for securing the at least four second upright hollow profiles;wherein the first modular unit is removably connected to the second modular unit via a connection mechanism, wherein the connection mechanism is released by actuation of a pedal element, and further wherein the modular units are independently mobile. 2. The cleaning trolley according to claim 1, wherein at least one of the first wall elements includes one or more seats, each of the one or more seats including a slot and a hole, and wherein a support plate for an element to be fixed to the cleaning trolley includes a tongue arranged along one edge of the support plate for insertion into the slot of one of the seats; and a drop-in pin arranged at the back of the support plate for a snap-fit insertion into the hole of one of the seats. 3. The cleaning trolley of claim 1 wherein the first modular unit includes two first crosswalls arranged opposite each other to form a drawer cabinet, and wherein one of the two first wall elements of each of the two first crosswalls includes a plurality of rails for guiding one or more drawers. 4. The cleaning trolley according to claim 1, wherein the first modular unit and the second modular unit further include lateral doors having hinges comprised of a fixed hinge leaf and a moving hinge leaf which is integral with the door, and wherein the hinges are self-closing and provide two rest positions separated from each other by 180°. 5. The cleaning trolley according to claim 4, wherein the two rest positions of the hinges are determined by an uneven profile of a support flange from which a hinge pin of the fixed hinge leaf protrudes and by an uneven profile of a rim surrounding a hinge hole of a hinge pin bushing of the moving hinge leaf, and wherein the uneven profile of the support flange and the uneven profile of the rim each include two opposite lowest points separated by peaks that are substantially complementary to each other and provide a mating interface. 6. The cleaning trolley according to claim 4, wherein the fixed hinge leaf comprises a flat section with a drop-in pin for a snap-fit insertion into a hole of one of the four first upright hollow profiles and an extension having a shape of a cramp for an enveloping grip with the edge of the one of the four first upright hollow profiles. 7. The cleaning trolley according to claim 1, wherein the first modular unit further includes a handle bar provided with one or more braces configured for removable attachment to one of the two first wall elements. 8. The cleaning trolley according to claim 7, wherein the braces include the handle bar at a height of from 50 to 200 cm above floor level. 9. The cleaning trolley according to claim 1, wherein at least one of the first upper frame and the second upper frame include an upper lid assembly comprising a frame and horizontally arranged sliding lids connected thereto for covering the top side of the trolley. 10. The cleaning trolley of claim 1 wherein each of the two first wall elements includes at least one seat, each seat configured to receive a support plate including one of a hook, a handle, a flat surface, and a clamp for holding a mop handle. 11. The cleaning trolley according to claim 3, wherein the one or more drawers include at least one of a tablet, a first drawer, a second drawer having 1.5 to 2.0 fold of a height of the first drawer and a third drawer having a smaller height than the first drawer. 12. The cleaning trolley of claim 1 wherein the first modular unit includes three first crosswalls arranged to form two drawer cabinets. 13. The cleaning trolley of claim 1 wherein at least one of the first modular unit and the second module unit includes a drawer cabinet.
