Pluto is unable to clear its orbital path of debris.
If by this question you mean why Pluto is no longer an official planet, it's because it is not the dominant object in its region of space.
Other dwarf planets in our solar system include Eris, Haumea, and Makemake. These dwarf planets are similar to Pluto in that they are smaller than traditional planets and do not meet all criteria to be considered full-fledged planets.
Pluto does not interact with any planets.
The dwarf planets in our solar system are Pluto, Eris, Haumea, Makemake, and Ceres. These objects are similar to planets in size but have not cleared their orbits of other debris, which is one of the criteria for being classified as a planet.
Pluto does not have an orbit clear of asteroids and debris. Planets do.
The answer for that is no. Pluto is now comsidered a dwarf planet. However, Pluto have many sisters and brothers. There are many dwarf planets that has been discovered. There maybe, some dwarf planets are still unknown because of the distance.
In terms of its physical characteristics, Pluto is relatively small and has a lower gravitational pull compared to the planets in our solar system. Therefore, it could be considered "weak" in that sense. However, Pluto's status as a planet or dwarf planet is not based on its strength but rather on its orbit around the Sun and other criteria defined by the International Astronomical Union.
Pluto has asteroids in its orbital path. Planets don't.
Pluto was removed from the list of planets in 2006 by the International Astronomical Union, as it did not meet the criteria to be classified as a planet due to its size and orbital characteristics.
When they discovered pluto did not follow the full criteria to be considered a planet. They needed a different scientific term to describe “planets” like pluto.

The three recognized dwarf planets in our solar system are Pluto, Eris, and Haumea. These objects meet the criteria for being dwarf planets, including not having cleared their orbital path of other debris and having sufficient mass for their gravity to shape them into a nearly round shape.
