I use WooCommerce REST API for updating/creating/deleting products. When I try to delete a product using $woocommerce->post('products/batch'), an image connected with a product is not deleting from the DB and filesystem. It takes up unnecessary space on the server.

What is the best way to resolve this problem?

I'd first get the attachment ID and with the attachment ID you could use wp_delete_attachment($att_id)

you can try this

$all_posts = get_posts(array(
    'numberposts' => - 1,
    'post_status' => 'any',
    'post_type' => get_post_types('', 'names') ,
));

foreach($all_posts as $all_post) {
    delete_post_media($all_post->ID);
}

function delete_post_media($post_id)
{
    if (!isset($post_id)) return;
    elseif ($post_id == 0) return;
    elseif (is_array($post_id)) return;
    else {
            $attachments = get_posts(array(
                    'post_type' => 'attachment',
                    'posts_per_page' => - 1,
                    'post_status' => 'any',
                    'post_parent' => $post_id
            ));
            foreach($attachments as $attachment) {
                    if (false === wp_delete_attachment($attachment->ID)) {

                            // Log failure to delete attachment.

                    }
            }
    }
}
