I tried to create the vaccum orb that collect all xp gem in the map, it temporally worked just as intended but there is a small issue.
If the xp gems are too far away from the player and the life span of their prefab are short (under 5s), they will disappear before touching player (player still get the correct amount of xp, iirc), life span around 10s would do the job.
VacuumPickUp.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class VaccumPickUp : MonoBehaviour
{
    public float pullSpeed = 10f;  // Speed at which the gems move toward the player
    private PlayerStats playerStats;  // Reference to the player's stats

    Vector2 initialPosition;
    float initialOffset;

    // To represent the bobbing animation of the object.
    [System.Serializable]
    public struct BobbingAnimation
    {
        public float frequency;
        public Vector2 direction;
    }
    public BobbingAnimation bobbingAnimation = new BobbingAnimation
    {
        frequency = 2f,
        direction = new Vector2(0, 0.3f)
    };

    void Start()
    {
        initialPosition = transform.position;
        initialOffset = Random.Range(0, bobbingAnimation.frequency);

        // Find the player stats (assuming PlayerStats script is attached to the player)
        GameObject player = GameObject.FindGameObjectWithTag("Player");
        if (player != null)
        {
            playerStats = player.GetComponent<PlayerStats>();
        } else
        {
            Debug.LogError("Player object not found. Make sure it has the 'Player' tag.");
        }
    }

    void Update()
    {
        // Apply bobbing animation even when not collecting XP
        transform.position = initialPosition + bobbingAnimation.direction * Mathf.Sin((Time.time + initialOffset) * bobbingAnimation.frequency);
    }

    void OnTriggerEnter2D(Collider2D other)
    {
        if (other.CompareTag("Player"))
        {
            // Start collecting all XP gems on the map
            CollectAllXP();
            // Optionally destroy the vacuum pickup object after use
            Destroy(gameObject);
        }
    }

    void CollectAllXP()
    {
        // Find all XP gems in the scene by their "XP" tag
        GameObject[] xpGems = GameObject.FindGameObjectsWithTag("XP Berry");

        // Loop through all the XP gems and collect them
        foreach (GameObject xpGem in xpGems)
        {
            Pickup pickupScript = xpGem.GetComponent<Pickup>();
            if (pickupScript != null)
            {
                // Call the Collect method to have the XP gem fly towards the player
                pickupScript.Collect(playerStats, pullSpeed);
            }
        }
    }
}

You don’t have to increase the lifespan of the Pickup. You can add a 3rd argument to the Collect() function to overwrite the default lifespan:

    void CollectAllXP()
    {
        // Find all XP gems in the scene by their "XP" tag
        GameObject[] xpGems = GameObject.FindGameObjectsWithTag("XP Berry");

        // Loop through all the XP gems and collect them
        foreach (GameObject xpGem in xpGems)
        {
            Pickup pickupScript = xpGem.GetComponent();
            if (pickupScript != null)
            {
                // Call the Collect method to have the XP gem fly towards the player
                pickupScript.Collect(playerStats, pullSpeed, 10);
            }
        }
    }
