In a specific implementation, the water cavity 9 is supported by the outer bucket 1 and is fixedly connected to the outer bucket 1 or a derivative part of the outer bucket 1. In this embodiment, the water pump 2 pumps water from the small cavity 4 and then delivers the water to the mop head a by means of the cleaning roller 8, and in the using process, the cleaning roller 8 makes contact with the mop head a, so that the cleaning effect is improved; and when water is stored in the water cavity 9, the cleaning roller 8 rotates to bring water to the mop head a, and under the effect of the cleaning roller 8, water can be distributed on the mop head a more uniformly.

(16) Preferably, the big cavity 3 and the small cavity 4 are formed by partitioning an inner bucket b which is arranged in the outer bucket 1, a partition plate b1 is arranged in the inner bucket b, and a gap is formed between the partition plate b1 and the inner wall of the inner bucket b; the partition plate b extends from an opening to the bottom of the inner bucket b and is connected to the inner wall or the bottom surface of the inner bucket b, a space formed between the outer side of the partition plate b1 and the inner bucket b is the big cavity 3, a space defined by the inner side of the partition plate b is the small cavity 4, and the partition plate b1 has a water passage. In a specific implementation, the water outlet 20 of the water pump 2 is close to the central axis of the support 5, the inner bucket b is fixedly connected to the outer bucket 1, and the upper surface of the big cavity 3 formed between the outer side of the partition plate b1 and the inner bucket b is impervious and is covered with a shield plate b2 or an extension part of the partition plate b1, so that water generated during centrifugal spin-drying will not flow into the big cavity 3, and thus, clean water and waste water will not be mixed. In this embodiment, the outlet of the water pump 2 is formed inside the inner side of the partition plate b1, water out of the water outlet 20 is sprayed to the mop head a, is then diffused from inside to outside under the effect of centrifugal force, and finally is collected and temporarily stored in the outer bucket 1, and the waste water can be poured out of the outer bucket 1 later.
