Abstract: A device for receiving a suction hose that connects a nozzle of a vacuuming device to a central unit of the vacuuming device. The device is has at least one holding device that can be arranged on the central unit of the vacuuming device, wherein the suction hose is able to be fitted in the at least one holding device such that the hose can be accommodated in a secure and stable manner. This advantageously makes it possible for the user of the vacuuming device to be able to adapt the length of the suction hose as required to the task currently to be performed. Here, the unused part of the suction hose is stored in a particularly secure and stable manner in the device or in cavities of the device that can be formed between the at least one holding device and a rear part. In a second aspect, the invention relates to a vacuuming device having a central unit that is connected to a suction hose having a nozzle.
