Estimating the term…
The present invention relates to a connection device for connecting a first cleaning cart to a second cleaning cart along a connecting direction, each configured for receiving cleaning utensils and comprising rollers for moving on a ground surface, wherein the connection device comprises a first connecting part fixed or fixable to the first cleaning cart and a second connecting part fixed or fixable to the second cleaning cart, wherein the respective connecting part comprises a base region and a projection region projecting therefrom in a direction towards the respective other connecting part, wherein a first locking element is arranged at the first projection region of the first connecting part and a second locking element is arranged at the second projection region of the second connecting part, wherein the locking elements are configured to be in engagement with one another when in a locking position and to be out of engagement when in an unlocking position, and wherein the projection regions are arranged transversely and in particular perpendicularly to the connecting direction, in lateral side-by-side relation to one another. The invention further relates to a cleaning system with two or more cleaning carts and a connection device.
