a mop base;

the cleaning roller is arranged in the mop seat;

2. The surface cleaner of claim 1, further comprising an upper cover that mates with the mop base, the upper cover being positioned on top of the mop base; one side of the upper cover is movably connected with the mop base, the other side of the upper cover is bent downwards to form a bent part matched with the cleaning roller, and a certain gap is formed between the bent part and the outer peripheral surface of the cleaning roller to form a centrifugal channel.

3. The surface cleaner of claim 2, wherein the mop base defines a first mounting space for mounting the cleaning roller therein, a bottom of the first mounting space is open, the centrifugal channel is located in the first mounting space, and a bottom of the bent portion forms a cleaning opening communicated with the first mounting space, so that the dirt enters the sewage tank through the cleaning opening, the centrifugal channel and the inlet.

4. The surface cleaner of claim 3, wherein the bottom of the bent portion is provided with a water retaining strip.

5. The surface cleaner of claim 2, wherein the inlet of the sump tank is angled and has an interference fit with the outer peripheral surface of the scrub roller.

6. The surface cleaner of claim 2, further comprising a nozzle assembly, wherein the nozzle assembly comprises a nozzle and a water jet pump connected with the nozzle for supplying water to the nozzle, the nozzle and the water jet pump are both mounted on the mop base, the nozzle is arranged towards the middle of the cleaning roller, and an included angle between a spraying direction of the nozzle and a central axis of the cleaning roller is an acute angle.

7. A surface cleaner according to claim 6 wherein at least two of the spray heads are spaced apart in the axial direction of the cleaning roller.

8. The surface cleaner of claim 6, further comprising a body hingedly connected to the mop base and a clean water tank connected to the water jet pump and removably mounted to the body.

9. The surface cleaner of claim 2, wherein the cleaning roller includes a roller shaft and an absorbent layer wrapped around an outer periphery of the roller shaft, the absorbent layer being a cleaning cloth.

10. The surface cleaner of claim 1, wherein the drive mechanism includes a drive motor and a timing belt assembly coupled to the drive motor, the drive motor is secured to one side of a motor bracket, the timing belt assembly is mounted to the other side of the motor bracket, the timing belt assembly includes a first pulley, a second pulley, and a timing belt coupling the first pulley and the second pulley, an output shaft of the drive motor passes through the motor bracket to couple to the first pulley, and the second pulley is coupled to the cleaning roller via a drive coupling disposed on the one side of the motor bracket.
