You can loop through all the woo-commerce products and delete them along with their attachment(images)..
$args = array( 'post_type' => 'product', ... );
$loop = new WP_Query( $args );
while ( $loop->have_posts() ) : $loop->the_post(); ?>
<?php wp_delete_post( $loop->post->ID );
wp_delete_attachment( $loop->post->attachment_id ); ?>
<?php endwhile; ?>
