## Abstract

The present invention relates to an upright vacuum cleaner having a main longitudinal extension, comprising a housing provided with a cavity, which cavity is formed between a bottom portion, and a frame portion, and a dust container comprising a wall and having two lateral sides, wherein the dust container is arranged in the cavity, and wherein the frame portion comprises at least two support bars arranged substantially in the longitudinal direction of the vacuum cleaner, one along each lateral side of the dust container, such that the at least two support bars contribute to the rigidity of the vacuum cleaner while a major portion of the wall of the dust container remains visible.

## Claims

### Claim 1

An upright vacuum cleaner having a main longitudinal extension, comprising a housing provided with a cavity, which cavity is formed between a bottom portion, and a frame portion of the housing, and a dust container comprising a wall and having two lateral sides, wherein the dust container is arranged in the cavity, and wherein the frame portion comprises at least two support bars arranged substantially in the longitudinal direction of the vacuum cleaner, one along each lateral side of the dust container, such that the at least two support bars contribute to the rigidity of the vacuum cleaner while a major portion of the wall of the dust container remains visible and wherein the frame portion further comprises at least two bottom support bars arranged in the bottom portion along each lateral side of the dust container.

### Claim 2 (depends on 1)

An upright vacuum cleaner according to claim 1, wherein the dust container is made, at least partially, of a transparent or semi transparent material.

### Claim 3 (depends on 2)

An upright vacuum cleaner according to claim 2, wherein the support bars of the frame portion are arranged such that essentially the entire inside wall of the dust container is visible from the outside of the vacuum cleaner.

### Claim 4 (depends on 1)

An upright vacuum cleaner according to claim 1, wherein the dust container is made completely of a transparent or semi transparent material.

### Claim 5 (depends on 1)

An upright vacuum cleaner according to claim 1, wherein the support bars of the frame portion are arranged such that the torsional rigidity of the vacuum cleaner at the cavity is substantially improved.

### Claim 6 (depends on 1)

An upright vacuum cleaner according to claim 1, further comprising a lower shaft for connecting the housing with a suction nozzle and an upper shaft for connecting the housing with a handle portion, wherein the at least two support bars are substantially aligned with an upper portion of the lower shaft and a lower portion of the upper shaft.

### Claim 7 (depends on 1)

An upright vacuum cleaner according to claim 1, wherein the support bars of the frame portion are arranged such that a left side portion and a right side portion of the dust container is visible through an opening between the bottom portion and each support bar.

### Claim 8 (depends on 1)

An upright vacuum cleaner according to claim 1, wherein each of the two bottom support bars meet one of the two support bars, respectively, such that a closed frame is formed around the opening on each lateral side of the dust container.

### Claim 9 (depends on 1)

An upright vacuum cleaner according to claim 1, wherein the dust container is releasably arranged in the housing for enabling removal and emptying thereof.

### Claim 10 (depends on 1)
