BACKGROUND [0001] 1. Technical Field [0002] The present application relates to a vacuum cleaner for removing dirt and debris from different surfaces and a method of operating a vacuum cleaner. [0003] 2. Background Information [0004] The present application relates to a hand vacuum cleaner with an upper handle in the form of a steering handle which is an extension of a housing and a floor vacuum attachment which is located in the vicinity of the floor, whereby the dirt-laden air is transported via a hand vacuuming hose which is in the form of an ascending line into an upper portion of the housing to a dust separator unit that is located upstream of a motor, and the exhaust air is guided outward via air outlets in the housing, and the hand vacuuming hose is located in the area facing the vacuum nozzle so that it can be detached to perform auxiliary vacuuming tasks. [0005] Hand vacuum cleaners are generally designed for use with floor attachments or nozzles. For other cleaning tasks, either other cleaning attachments are connected to the vacuum cleaner body or a hand-held vacuuming hose is used instead of the floor nozzle. Both solutions have the disadvantage that either the equipment is difficult to handle, or the process of converting the unit from one operation to another is complex and time-consuming, because the objective is to make possible a rapid change between the types of operation. In addition, it is conventional on vacuum cleaners to route the air that is sucked in, after it is passed through a dirt trap and the filter, through an exhaust conduit to a plurality of housing slots that are located next to one another. The air exits these slots in the housing at significant flow velocities. On account of the relatively high concentration of the air flow, the exhaust can be very noisy, and to some extent, some components of the noise are also transmitted from the vicinity of the motor. [0006] For technical reasons related to fluid flow, it is desirable to make the exhaust duct and the exit point in the vicinity of the housing of the vacuum cleaner as large as possible, to thereby create a low exhaust resistance. In direct contradiction to these requirements, however, a reduction of acoustical emissions is also required, which could be achieved by a relatively high flow resistance. These contradictory requirements have not been satisfactorily resolved by the prior art. OBJECT OR OBJECTS [0007] The object is to improve a system of the prior art, and while retaining the suitability for floor cleaning, to make the use of an integrated hand-held vacuuming hose immediately available, as well as an additional handle for the operation and for transport of the unit, which guarantees a filter that is located on the housing, to make possible low air flow speeds with a large exhaust area. SUMMARY [0008] The present application teaches that the housing in the form of a vacuum cleaner body has, in the central area, an approximately cylindrical configuration in the form of an independent element, which is sheathed by filter material in the form of an exhaust filter and the exhaust air can be fed into a jacket chamber that is formed between the housing and filter material for exhaust, and in an area facing the motor compartment, passages to the jacket chamber are realized, and an outboard receptacle element for the hand-held vacuuming hose is provided, whereby the receptacle element is connected to the housing with some distance left open in between, with the realization of a reach-through opening for the replacement of the filter material. [0009] Consequently, the overall appearance of the unit is preserved while the ease of operation of the vacuum cleaner body is increased, and it is also possible to avoid any adverse effects on a surrounding exhaust filter that is located in the vicinity of the housing. [0010] In one advantageous configuration, the receptacle element is realized essentially in the form of a shell, in the manner of a curved receptacle. [0011] When the receptacle element is realized in the shape of a shell, it is possible to realize at least the lower portion of the receptacle element in a tubular shape. [0012] Alternatively, the present application teaches that the receptacle element can be realized in the manner of a curved receptacle, and is connected detachably to form a hand-held vacuuming element that can be removed from the body of the vacuum cleaner. [0013] The present application also teaches that the receptacle element is detachably connected with the vacuum cleaner body in the connecting areas by means of lockable mating connecting elements. [0014] The above-discussed embodiments of the present invention will be described further hereinbelow. When the word "invention" or "embodiment of the invention" is used in this specification, the word "invention" or "embodiment of the invention" includes "inventions" or "embodiments of the invention", that is the plural of "invention" or "embodiment of the invention". By stating "invention" or "embodiment of the invention", the Applicant does not in any way admit that the present application does not include more than one patentably and non-obviously distinct invention, and maintains that this application may include more than one patentably and non-obviously distinct invention. The Applicant hereby asserts that the disclosure of this application may include more than one invention, and, in the event that there is more than one invention, that these inventions may be patentable and non-obvious one with respect to the other.
