- the battery device is arranged on the device body in such a way that a center of mass of the battery device lies at least approximately on the center plane .
- Batteries of the battery device have a relatively high mass.
- the center of gravity of the battery device is on the center plane. As a result, no tilting moment or no relevant tilting moment results from the positioning of the battery device on the device body.
- the suction device can be held or lifted, for example, without an operator having to compensate for tilting moments.
- the suction device according to the invention has a high level of stability.
- the battery device is arranged on the center plane and/or is arranged symmetrically to the center plane on the device body; the battery device comprises a plurality of battery units which are arranged on the center plane and/or are arranged symmetrically with respect to the center plane; the filter cleaning device is arranged on the center plane and/or is designed symmetrically to the center plane; the filter cleaning device has a plurality of external air valves, which are arranged on the central plane and/or are arranged symmetrically to the central plane on the device body.

- the arrangement of the battery device makes it possible to prevent or at least minimize a tilting moment in relation to the central plane. This results in a high level of stability.
- the suction device can easily be raised for an operator. This results in particular from the fact that the central plane lies in the middle between the first longitudinal side and the second longitudinal side.
- the median plane is transverse to the first transverse side and the second transverse side.
- the first transverse side can be used, for example, to fix or remove a battery unit of the battery device on the device body.
- a charge status display can be observed on the first lateral side.
- Simple operability and a compact structure result when a suction connection and/or an operating panel are arranged on the first lateral side.
- a wheel axle of a wheel device is oriented transversely and, in particular, perpendicularly to the center plane. This results in a high level of stability. A tilting moment can also be kept low with respect to a plane which is perpendicular to the center plane due to the wheel axle being oriented transversely to the center plane.
- a compact structure results when the impeller lies on the center plane with respect to an axis of rotation.
- a carrying handle is at the midplane, an operator can lift the tool body without substantial tilting even when the battery pack is fixed to the tool body. As a result, the operator does not have to provide a compensating force and is therefore easier to operate.
- the center of gravity on the center plane can be specified in a simple manner.
- suction connection and/or the control panel on the middle level result in a compact design that is easy to operate.
- the battery device includes (at least) a first battery unit and a second battery unit, wherein a battery unit is a battery and in particular a rechargeable battery, or is a counterweight that corresponds to a battery in terms of weight.
- the suction device is operated with only one battery unit, then it is advantageous if a balancing weight is fixed symmetrically to this electrically active battery unit on the device body, so that no tilting moment occurs. If several electrically effective battery units are used on the device body, the result is a longer service life for the suction device.
- the first battery unit and the second battery unit are arranged on the device body at a distance from the center plane; the first battery unit and the second battery unit have a spacing direction which is transverse and in particular perpendicular to the median plane; the first battery unit and the second battery unit sit mirror-symmetrically or point-symmetrically to the center plane on the device body; the first battery unit and the second battery unit are spaced apart from the filter cleaning device on the device body; the first battery unit and/or the second battery unit is detachably fixable or fixed to the device body.
- the suction device can be made compact. It is easy to use. A center of mass of the battery unit can be "positioned" in a simple manner on the geometric center plane. As a result, a tilting moment is reduced. The result is a high level of stability. For example, an operator can easily raise or lower the machine body.
- the functioning of the filter cleaning device is not impeded and no compromises have to be made with regard to the functioning of the filter cleaning device due to the necessary positioning of the battery units.
- first battery unit and/or the second battery unit can be or are fixed in a detachable manner on the device body, then charging can take place on an external charging device. This results in a compact design of the suction device.
- the centers of the battery units or the filter cleaning device can be centers of mass of the corresponding components or geometric centers. A symmetrical arrangement is achieved by the triangular arrangement. This results in a high level of stability of the suction device. Furthermore, the components are arranged in a compact manner, so that the dimensions of the suction device—even if a filter cleaning device is provided—can be kept small.
- the device body has a receptacle (a receptacle space) for the filter cleaning device and/or the filter device, which is closed with a movable cover.

When the cover is released (either completely or for example by folding it over), the filter cleaning device can be accessed, for example for maintenance purposes. If necessary, a filter device can be exchanged via an open cover. If the battery device is at a distance from the cover, then this access is not impeded or made difficult by the battery device. For the same reason, it is favorable if the battery device is at a distance from an air duct device of the filter cleaning device. External air for cleaning the filter device can be supplied via the air duct device. By spacing the battery device from the air duct device, no compromises have to be made with regard to the functionality of the filter cleaning device due to the presence of the battery device.
- the device body has a first transverse side and has a spaced-apart second transverse side, the center plane being oriented transverse to the first transverse side and/or transverse to the second transverse side, the device body having a first part on which the first transverse side, and having a second part on which the second transverse side is formed, with at least one of the following: the battery device is arranged on the first part; the filter cleaning device and the filter device are arranged on the second part; the battery device is closer to the first transverse side than to the second transverse side; the filter cleaning device and the filter device are closer to the second transverse side than to the first transverse side; the fan means is closer to the first transverse side than to the second transverse side or is midway between the first transverse side and the second transverse side;

- the battery device is positioned on an intermediate ring, which is arranged in particular between a suction head and a suction material container. Due to this intermediate ring, the suction head does not have to be modified to accommodate a battery device. The suction material container also does not have to be modified. The battery device can be positioned on the intermediate ring between the suction head and the suction material container and thereby outside of the suction head and outside of the suction material container.
