Most pipes under the floor are 2, 3 or 4-inches in diameter. The piping for sinks and similar fixtures inside the wall are 1 1/4-inch or 1-1/2 inch in diameter. Just like the branches on a tree, every branch line in a home gets larger as it gets closer to the main line.
A small hand snake is designed to open minor clogs in small traps or branches. They are not designed to clear the lines under your floor. If the floor line is clogged, you need something bigger for the sewer cleaning.
When drain cleaning, you need to use the cutting blades that are set to the inside diameter of the pipe. So to clear a 2-inch drain you would need a pair of 2-inch blades. If not, a 2-inch blade in a 3-inch pipe will leave 1-inch of scum in the pipe.
