(14) Referring now more specifically to the drawings by numerals of reference, FIGS. 1-4 show various views of a floor cleaning device 100.

(15) FIG. 1 shows a floor cleaning device 100 during an ‘in-use’ condition. Here, floor cleaning device 100 may clean hard-to-reach areas of a floor without the user having to get down on the floor and scrub them by hand. As illustrated, floor cleaning device 100 may include mop head 110 that includes cleaning fibers 200. Furthermore, floor cleaning device 100 may include a corner brush 120 coupled to an inner handle 130 that is extendable from a center of mop head 110. Floor cleaning device 100 may include an inner handle 130 including knob 406 for engaging and disengaging a locking mechanism 404 for locking corner brush 120 in position.

(16) FIG. 2 shows the floor cleaning device 100 of FIG. 1. As above, floor cleaning device 100 may include mop head 110. Mop head 110 may include cleaning fibers 200 configured to suit the overall construction of mop head 110. In some versions, cleaning fibers 200 may also include a sufficiently absorbent material to facilitate removing cleaning products from a surface. And cleaning fibers 200 may be shorter than the length of inner handle 130. Mop head 110 may also include opening 202 positioned centrally to cleaning fibers 200 to allow passage of inner handle 130.

(17) Corner brush 120 may include cleaning bristles 201. Corner brush 120 may further comprise triangularly arranged cleaning bristles 201 to facilitate reaching a corner between two walls. And corner brush 120 may be coupled to inner handle 130 so that corner brush 120 may extend and retract with inner handle 130. Corner brush 120 may mount angled relative to inner handle 130 to facilitate comfortable use. In some versions, facilitate comfortable use means facilitate use that does not involve excessive bending.

(18) FIG. 3 is a perspective view of floor cleaning device 100 and shows that corner brush 120 may mount to inner handle 130, which may connect to inner handle 130. Inner handle 130 may extend through opening 202. As inner handle 130 is extended, it passes through opening 202 that sits centrally on mop head 110. Since corner brush 120 connects to inner handle 130, the extension of inner handle 130 extends corner brush 120. Inner handle 130 is significantly (such as 10, 20, 30, 40, or 50%) longer than cleaning fibers 200. In some versions, this greater length helps prevent cleaning fibers 200 from interfering with or with using corner brush 120. In some versions, corner brush 120 fits into a corner between two adjacent walls. In these or other versions, corner brush 120 is smaller than mop head 110. In some versions, cleaning fibers 200 comprise the same material as cleaning bristles 201. In these or other embodiments, cleaning fibers 200 have the same shape as cleaning bristles 201.

(19) FIG. 4 is also a perspective view of floor cleaning device 100. In this version, inner handle 130 passes through outer handle 150 and locking mechanism 404. Knob 406 attaches to the upper end of inner handle 130 and connects to locking mechanism 404 to facilitate locking and unlocking locking mechanism 404. Specifically, locking mechanism 404 sits at the end of outer handle 150, and knob 406 sits at the end of inner handle 130. In some versions, knob 406 is spaced apart from locking mechanism 404. Inner handle 130 may be positioned among a plurality of operative modes, including extended and retracted modes or positions. Twisting knob 406 may engage and disengage locking mechanism 404. Other methods of engaging and disengaging locking mechanism 404 may suit the design, construction, or needs of floor cleaning device 100.

(20) FIG. 5 is a flow diagram illustrating a method for cleaning a floor 500, according to an embodiment of the present disclosure. In particular, the method for cleaning a floor 500 may include one or more components or features of floor cleaning device 100, as described above. As illustrated, the method for cleaning a floor 500 may include the steps of step one 501, mopping a floor with a mop head until a user encounters a corner; step two 502, twisting the knob to disengage locking mechanism; step three 503, extending inner extendable handle to extend the corner brush; step four 504, twisting the knob to engage the locking mechanism; step five 505, cleaning a corner using the corner brush; step six 506, twisting the knob to disengage locking mechanism; step seven 507, retracting inner extendable handle to retract the corner brush; step eight 508, twisting the knob to engage the locking mechanism.

(21) FIG. 6 depicts a close-up view of joint 605 between locking mechanism 404 and outer handle 150. In this version, outer handle 150 has outer threads 1402 on the outside surface 601 of its upper end 650. Locking mechanism 404 has inner threads 1404 near its lower end 1410. In some versions, inner threads 1404 on lower end 1410 begin a distance upward from lower end 1410. Inner handle 130 extends upward from locking mechanism 404 and downward through locking mechanism 404 into and through outer handle 150. Taper lock 610 sits above inner threads 1404. In some versions, taper lock 610 is cylindrical and fits over inner handle 130. Taper lock 610, along the upper part 615 of taper lock 610, tapers inward such that the inner diameter of taper lock 610 remains substantially constant while the outer diameter of upper part 615 tapers to a reduced diameter.

(22) Taper lock 610 abuts upper end 650 of outer handle 150. Outer handle 150 substantially prevents taper lock 610 from moving downward along inner handle 130. Locking mechanism 404 has a tapered cavity 655 upward from inner threads 1404. Cavity 655 provides clearance for taper lock 610. In some versions, locking mechanism 404 threads onto outer handle 150. This causes upper end 650 to push against the bottom of taper lock 610. At that point, further movement causes taper lock 610 to move further into tapered cavity 655 until it contacts wall 656. Further threading causes upper end 650 to push against the bottom of taper lock 610 hard enough to cause taper lock 610 to wedge between wall 656 and inner handle 130 securing inner handle 130 in place relative to outer handle 150. Thus, inner handle 130 is locked in place by locking mechanism 404.

(23) FIG. 7 depicts a close-up view of the joint 700 between mop head 110 and outer handle 150. The lower end 701 of outer handle 150 comprises outer threads 1406 on outside surface 705 of outer handle 150. Mop head 110 has a socket 710 that comprises inner threads 1408 on inside surface 715 of socket 710. Threads 1408 receive threads 1406 to attach mop head 110 to outer handle 150. In some versions, threads 1406 extend into threads 1408 far enough to cause tip 716 to contact surface 717. In other versions, threads 1406 do not extend into threads 1408 far enough to cause tip 716 to contact surface 717. In these versions, space 720 sits between tip 716 and surface 717. Sometimes, space 720 facilitates assembly of mop head 110 onto outer handle 150.

(24) FIG. 8 depicts a top end 810 of inner handle 130. Knob 406 connects to top end 810. Knob 406 has base 815 and an elongate post 820 extending downward from base 815 into inner handle 130. Elongate post 820 is necked down and has a smaller diameter than base 815. As assembled, inner surface 840 of inner handle 130 contacts outer surface 825 of elongate post 820. In some versions, this contact results in a friction fit between knob 406 and inner handle 130. In other versions, an adhesive or glue is used on inner surface 840, outer surface 825, or both to secure elongate post 820 into inner handle 130.
