Abstract

A floor sweeper is disclosed. The floor sweeper has a handle, a main body including a detergent compartment, a roller mechanism including a roller with a washing belt thereon, a scraper and a waste fluid compartment. Detergent is dripped from the detergent compartment onto the washing belt. The washing belt washes a floor and wipes stains therefrom due to frictional contact therewith during the forward motion of the floor sweeper. Waste fluid soaked into the washing belt is squeezed from the belt by the scraper and is collected in the waste fluid compartment during the backward motion of the sweeper.

Claims

1. A floor sweeper comprising:

a sweeper body;

a handle connected to said sweeper body for moving said sweeper body;

roller means within said sweeper body for washing and wiping a floor, said roller means comprised of a roller rotatably mounted in said body and a washer belt on the outside of said roller;

a liquid compartment within said sweeper body above said roller means, said liquid compartment being adapted to hold liquid therein and supply said liquid to said washer belt therebeneath;

stopper means within said sweeper body adjacent said roller means for preventing said roller means from rotating when said sweeper body is moved forward and for allowing said roller means to rotate when said said sweeper body is moved rearward;

scraper means contacting said washer belt for squeezing liquid from said washer belt when said roller means is rotated; and

waste fluid container means adjacent said scraper means for collecting fluid squeezed from said washer belt by said scraper means.

2. A sweeper as claimed in claim 1, further comprising valve means in said liquid compartment for allowing a predetermined amount of liquid in said compartment to flow from said compartment toward said roller means.

3. A sweeper as claimed in claim 1, further comprising:

a plurality of elliptical bearing member means within said sweeper body for rotatably mounting said roller means therein, one bearing member means being at each end of said roller means, and each of said bearing member means having an opening at its lower side for receiving said roller means therein.
