The reset member (5) is configured as a linear spring (501), one end of which abuts against the pressure plate (3021) and the other end acts on the tensioning assembly (4).

5. The surface cleaning apparatus of claim 4 wherein, The walking mechanism (II) further includes a housing (6), which includes a drive wheel seat (601). The drive wheel seat (601) has a mounting surface (6011) for mounting the two drive wheels (1) and the conveyor belt (2), and the fixing part (301) is fixedly connected to the mounting surface (6011) so that the drive wheels (1), the conveyor belt (2), the reset member (5) and the tensioning assembly (4) can be mounted on the mounting surface (6011) from the opposite side of the mounting surface (6011).

6. The surface cleaning apparatus of claim 2, wherein, The tensioning assembly (4) includes a first tensioning assembly (4-1) and a second tensioning assembly (4-2); The first tensioning assembly (4-1) and the second tensioning assembly (4-2) are both mounted on the same support (302); The first tensioning assembly (4-1) is disposed on the inner side of the conveyor belt (2) between the two drive wheels (1) on the side closer to the surface to be cleaned, and the second tensioning assembly (4-2) is disposed on the inner or outer side of the conveyor belt (2) between the two drive wheels (1) on the side away from the surface to be cleaned.

7. The surface cleaning apparatus of claim 2, wherein, The tensioning component (4) is rotatably mounted on the support (302).

8. The surface cleaning apparatus of any of claims 2-7, wherein, The tensioning assembly (4) includes a tensioning structure (401) and a floating support (402). The tensioning structure (401) is connected to the floating support (402) and abuts against the conveyor belt (2) in the width direction of the conveyor belt (2); The floating support (402) is configured to extend along the width direction of the conveyor belt (2) and be centered relative to the centerline of the width direction of the conveyor belt (2); The reset member (5) applies an elastic force to the compression surface (4021) of the floating bracket (402) and is centrally located relative to the floating bracket (402).

9. The surface cleaning apparatus of claim 8, wherein, The floating support (402) includes a floating plate (4022) for mounting the tensioning structure (401), and the other end of the reset member (5) applies the elastic force to the floating plate (4022); the support (302) includes a pressure plate (3021) extending from the fixing part (301) into the conveyor belt (2) along the width direction of the conveyor belt (2), and a floating space (403) with the reset member (5) built in is provided between the floating plate (4022) and the pressure plate (3021).
