1. A cleaning cart, comprising: a base plate including a first outer boundary and a first fastening region having a first area; anda working plate including a second outer boundary and a second fastening region having a second area, the working plate being arranged at a vertical distance above the base plate,wherein the base plate and the working plate are connected to each other by a linkage arranged within the vertical distance,wherein the linkage includes first and second struts extending in a non-parallel manner with respect to each other, the first and second struts each having a first end-side end and a second end-side end opposite the first end-side end,wherein the first and second struts are in each case connected at the first end-side end of the strut to the first fastening region of the base plate, and in each case connected at the second end-side end of the strut to the second fastening region of the working plate,wherein the first area is smaller than the second area, andwherein the base plate includes a depositing area suitable for accommodating cleaning utensils inside the outer boundary of the respective plate and radially outside of the struts. 2. The cart of claim 1, wherein the first end-side ends of the struts are at a first distance from each other, and the second end-side ends of the struts are at a second distance, and wherein the first distance is smaller than the second distance. 3. The cart of claim 1, wherein the first and second struts are arranged trapezoidally with respect to each other, transversely with respect to a main travel direction of the cleaning cart. 4. The cart of claim 1, wherein the end-side ends are arranged in a frictional and/or form-fitting manner in respective recesses of the base plate and/or of the working plate. 5. The cart of claim 4, wherein the recesses have a depth, and wherein a ratio of the depth of the recesses, in which corresponding struts are accommodated, to a length of a main axis of accommodated struts is 1 to 3. 6. The cart of claim 1, wherein the first and second struts are identical parts. 7. The cart of claim 1, wherein the first and second struts each have a profile which is closed in a circumferential direction and does not include undercuts. 8. The cart of claim 1, wherein the first and second struts each have a cross section differing from a circular shape. 9. The cart of claim 1, wherein the first and second struts have an elliptical cross section, with a respective main axis which extends substantially in a main travel direction of the cleaning cart. 10. The cart of claim 9, wherein main axes of the first and second struts arranged trapezoidally with respect to each other are arranged converging with respect to each other in a main travel direction. 11. The cart of claim 10, wherein main axes of the first and second struts enclose an angle of 2° to 45° in a main travel direction. 12. The cart of claim 1, wherein the working plate is larger than or the same size as the base plate, transversely with respect to a main travel direction. 13. The cart of claim 1, wherein the first fastening region together with the first outer boundary bounds a depositing area for at least one cleaning utensil. 14. The cart of claim 13, wherein the depositing area has a width of at least 50 mm. 15. The cart of claim 1, wherein the base plate is larger than the working plate, transversely with respect to a main travel direction. 16. The cart of claim 1, wherein the linkage includes no further strut beyond the first and second struts. 17. The cart of claim 1, configured to accommodate elongated cleaning utensils extending from the working plate to the cleaning plate.
