## Abstract

A cleaning system includes: a bucket; a cleaning device with a mop head, the mop head including a carrier body and cleaning fringes that are fixed to the carrier body, the carrier body being connected to a stick on its side facing away from the cleaning fringes; and a washing-out device arranged in the bucket for washing out the cleaning fringes, the washing-out device including a basket settable into an upward and downward movement by a first actuating device, and a spinning device arranged in the bucket for spin-drying the cleaning fringes, the spinning device including the basket, which is settable into rotational movement by a second actuating device, and a centering pin, which is arranged in the basket and centers the cleaning device. The carrier body is essentially disk-shaped, with a circumferential boundary and with a maximum extension d1 between two circumferential areas opposite to each other.

## Claims

### Claim 1

A cleaning system, comprising:
a bucket;
a cleaning device with a mop head, the mop head comprising:
a carrier body, and
cleaning fringes that are fixed to the carrier body, and
a stick on its side facing away from the cleaning fringes, wherein the carrier body is connected to the stick; and
a washing-out device arranged in the bucket and configured to wash out the cleaning fringes, the washing-out device comprising:
a basket settable into an upward and downward movement by a first actuating device,
a spinning device arranged in the bucket, the spinning device configured to spin-dry the cleaning fringes, and
a centering pin, which is arranged in the basket and configured to center the cleaning device,
wherein the basket is settable into rotational movement by a second actuating device,
wherein the carrier body is essentially disk-shaped, with a circumferential boundary and with a maximum extension d1 between two circumferential areas opposite to each other,
wherein the basket is rotationally symmetrical, with a maximum clear first width d2, and
wherein a first ratio of d2 to d1 is ≥1.5,
wherein responsive to the first actuating device being actuated, the basket is arranged at a high point in the bucket that is above an essentially mean water level in the bucket, and
wherein responsive to the first actuating device not being actuated, the basket is arranged at a low point in the bucket that is at least partially below the essentially mean water level in the bucket.

### Claim 2 (depends on 1)

The cleaning system according to claim 1, wherein the first ratio is 1.5 to 2.5.

### Claim 3 (depends on 1)

The cleaning system according to claim 1, wherein the cleaning fringes protrude radially from the carrier body,
wherein the cleaning fringes have a maximum radial extension d3, and
wherein a second ratio of d3 to d2 is >1.

### Claim 4 (depends on 3)

The cleaning system according to claim 3, wherein the second ratio is 1.25 to 1.75.

### Claim 5 (depends on 3)

The cleaning system according to claim 3, wherein the bucket surrounds the basket with a radial distance and, as viewed over an axis of rotation of the basket, has a clear second width d4, and
wherein a third ratio of d3 to d4 is >1.

### Claim 6 (depends on 5)

The cleaning system according to claim 5, wherein the third ratio is 1.25 to 1.75.

### Claim 7 (depends on 3)

The cleaning system according to claim 3, wherein the carrier body and the basket delimit an essentially circular ring-shaped annular space,
wherein the annular space has a radial width W, and
wherein a fourth ratio of W to d3 is ≥0.25.

### Claim 8 (depends on 7)

The cleaning system according to claim 7, wherein the fourth ratio is 0.33 to 0.67.

### Claim 9 (depends on 1)

The cleaning system according to claim 1, wherein the centering pin is arranged in an axis of rotation of the basket, and
wherein the centering pin and the basket are connected to each other in a destruction-free releasable and force-fitting and/or form-fitting manner.

### Claim 10 (depends on 1)

The cleaning system according to claim 1, wherein the first actuating device comprises a lever with at least one articulation, and
wherein the centering pin is arranged on a first side of the at least one articulation and a first actuating pedal is arranged on a second side of the at least one articulation.

### Claim 11 (depends on 1)

The cleaning system according to claim 1, wherein the second actuating device comprises a second actuating pedal and a gearing mechanism configured to convert a translational movement of the second actuating pedal into a rotational movement of the basket.

### Claim 12 (depends on 1)

The cleaning system according to claim 1, wherein the bucket has an internal height that is fillable to a maximum height with a cleaning liquid and that corresponds essentially to twice a height of the essentially mean water level in the bucket and essentially to twice a height of the basket.
