Description

Description: TECHNICAL FIELD The present invention relates to a cleaning device having a main vacuum cleaner and an auxiliary vacuum cleaner.

2. Description of the Related Art There are the following three typical types of conventional cleaning devices. That is, one of them is a floor moving type, in which a floor nozzle is connected to a vacuum cleaner having wheels for moving the floor via a hose and an extension pipe. The other one is an upright type, in which a handle, a fan motor dust collector and a floor nozzle are linearly and integrally arranged.

The other one is a hand-held type called a handy type, and is often a cordless type using a secondary battery as a power source. In some cases, a combination of the two, for example, a combination of an upright type vacuum cleaner and a hand-held type vacuum cleaner is also found.

Problems to be Solved by the Invention However, any of the above-mentioned types of vacuum cleaners have advantages and disadvantages, and cannot be said to be sufficient in terms of usability. That is, the floor moving type has a small operation labor, but on the other hand, the vacuum cleaner is drawn through a hose, so that it is difficult to use in places where there are many obstacles.
The upright type does not have such a drawback, but has the drawback that the weight of the vacuum cleaner is added to the operator and the operation labor is large.

The hand-held type can be easily cleaned, but is not suitable for cleaning large places.

Therefore, several types of vacuum cleaners have conventionally been required to meet the cleaning conditions.

Furthermore, in combination type vacuum cleaners, only an independent vacuum cleaner is combined, and the combination cannot be used effectively.
