Drawing multiple sprites with clear screen for every frame

Question

I googled with best of my skills, but I cannot find any relevant answer to my problem. I'm making a game with an isometric view. I need to draw multiple sprites on the screen and before switching to next frame of the sprite, it is needed to clear the last frame of the sprite by doing a clearScreen of the window. If I do clearScreen, all of the other sprites get cleared, since the program cannot remember the last state of the screen. How can I overcome this problem?

Here is my code (I'm writing in pseudo-code, so that the solution can become implementation independent)

main.cpp
{
  //gameloop 

 Animation playerAnimation;

  while(window.isopen())
  {
    window.draw(game_map);

   if(certain_condition_is_met)
   playerAnimation.update(window)

    window.clear()
    window.display();
  }
}

   Animation.cpp

   class Animation
   {
     void update(&window) 
      {
        for(available_frames frame)
         window.draw(frame);
       //inside the above for loop ,i need to do a clearscreen to avoid overlap of 
       //frames,but this will make other sprites to be lost 
       }
   }

I'm using C++ SFML, in which there is no way to update a particular sprite without clearScreen.

In case you needed a code example

class Animation
{
    void update()
    {
        if (condition)
        {
            advanceFrame();
        }
        frame.draw();
    }
}

Animation animation;

int main()
{
    while (window.isOpen())
    {
        window.clear();
        animation.update();
        window.display();
    }
}

The condition is most likely a timer, to update the animation every few milliseconds. This way, the animation is drawn once per update.
