A vehicle for removing an accumulation of particles comprises a vehicle body, a system configured to remove the particles in bulk, and an arm coupled to and extending from the vehicle body. The arm comprises a first sweeping element and a second sweeping element. Each sweeping element includes a shaft member rotatable about a longitudinal axis, and a set of bristles projecting away from the axis along the shaft member. The first and second longitudinal axes are a distance apart, and the sweeping elements define a concerted sweeping area. The arm may be movably coupled to the vehicle body and may be configured to move the sweeping element around the vehicle body by rotating the arm about a horizontal axis. When a sweeping element rotates in proximity to the ground, the longitudinal axis is substantially vertical. The vehicle may further include a computer system for tracking the location of an object.
