This application discloses a side brush and a smart cleaning device. The side brush includes a side brush base for mounting to a smart cleaning device and a scraper connected to a peripheral side of the side brush base. The scraper is configured to be in contact with the floor, so as to scrape sundries. A structure of the side brush can effectively prevent the side brush from being entangled with sundries during cleaning.

A toothbrush capable of inhibiting damage of an oral cavity of a user that includes: a head section that has a bristle implanting surface on a front end side; a handle section that is disposed on a rear end side from the head section and has a handle section main body; and a neck section that is disposed between the bristle implanting surface and the handle section. The toothbrush has a deforming portion that is located on the rear end side from the bristle implanting surface and is deformed, while stress characteristics associated with bending due to an external force acting on the head section are in a plane stress condition.

An infinity brush has a flaccid belt configured to define a lemniscate. A plurality of work-contacting segments protrude from and are carried by the flaccid belt. A mechanical drive rotates the flaccid belt. Various embodiments of the flaccid belt include a single lemniscate, a plurality of lemniscates, and various simulated lemniscates. In one embodiment, the infinity brush bristle includes non-cylindrical brush bristles with a longitudinal shaft having at least one diameter transition, while other bristles comprise beads of various oval, circular, and cylindrical geometries.

An illustrated view of an exemplary straw cleaning system for cleaning and sanitizing a straw as well as for providing a clean container to store the straw. The straw cleaning system has a straw with an expandable area. The straw is placed in a straw holder. The straw holder having a hole in the bottom to drain liquid of the straw. A straw brush is then placed into the straw and cap of the straw brush is coupled to the straw container. The cap fits around an outside of the straw holder to seal the straw in the straw holder. The straw brush has a brush with soft bristles for cleaning residue from inside of the straw.
