Problems solved by technology

However, the above mentioned hand-held vacuum cleaners suffer a number of disadvantages.
One disadvantage is that the filter elements are often small and tend to clog with debris relatively quickly.
This disadvantage arises as a result of the compact nature of these hand-held vacuum cleaners.
Thus, the overall vacuum and pickup efficiency of the cleaner is reduced as well.
Another disadvantage with prior hand-held vacuum cleaners is that they do not provide a convenient method of emptying the dirt which accumulates in the dirt cup of the cleaner.

Embodiment Construction

[0024] With reference to FIG. 1, a first embodiment of a hand-held vacuum cleaner 100 is shown. The hand-held vacuum cleaner 100 generally includes a housing 110, a suction nozzle 112, a handle 114, a dirt cup 116 and a suction fan and motor assembly 118 (FIG. 8). As shown in FIG. 1, the housing 110 can be formed of two bilaterally symmetrical pieces, a left half portion and a right half portion. Of course, other housing constructions are also contemplated. As can be seen in FIG. 9, the suction fan and motor assembly 118 is disposed internally to the housing 110. The suction nozzle 112 can be disposed adjacent a first end 110a of the housing 110, whereas the dirt cup 116 can be disposed adjacent a second end 110b of the housing 110.

[0025] Now with reference to FIG. 2, a perspective view of the first embodiment 100 of the hand-held vacuum cleaner is shown with the dirt cup 116 removed from the housing 110. A plurality of nubs 120 are disposed along the second end 110b of the housing...

[0001] This application is a continuation-in-part of application Ser. No. 29 / 221,441, filed on Jan. 14, 2005, and Ser. No. 29 / 221,442, filed on Jan. 14, 2005, and Ser. No. 29 / 237,958, filed on Sep. 8, 2005.BACKGROUND [0002] The present invention relates to the field of vacuum cleaners. It finds particular application in conjunction with vacuum cleaners which employ cyclonic separation. [0003] Vacuum cleaners have become extremely popular for cleaning a variety of surfaces in homes, offices, cars or the like. One well known type of vacuum cleaner is a portable hand-held unit. Such units are utilized typically for small clean-up jobs or for cleaning in hard-to-reach places. These portable vacuum cleaner units are relatively light-weight and have a handle in order to enable a user to readily employ them in places where canister, upright, or shop-type vacuum cleaners cannot be used or are inconvenient to use. [0004] However, the above mentioned hand-held vacuum cleaners suffer a number ...
