A cleaning apparatus comprising: i. a main body comprising: a plurality of brush heads of bristles, a plurality of brush bases which the bristles are attached to, a plurality of channel shaped sections that hold said plurality of brush bases with brush heads attached to, wherein each brush base can bend flexibly and independently to each other; and a tension device; and ii. a shaft-like piece that is attached to the main body at one end and slides into an extension handle at the other end, said shaft-like piece further comprising a tension clip which locks the shaft-like piece into said extension handle; wherein said tension device is disposed between said each brush base and said each channel shaped section, said plurality of brush bases are independent of said plurality of channel shaped sections and said plurality of channel shaped sections are hinged with each other, an intersection between two channel shaped sections is cross-spanned with a brush base so that a bend between two channel shaped sections does not cause a space between two brush bases.
