We have been advised by management that this product does need time to map out your pool, therefore, will take longer the first few times of use. If you aren't satisfied with the product, please contact our Warranty Department which can arrange a return label for the item at no charge to you. We are also more than happy to offer other suggestions on another cleaner if you are interested? Our priority is our customers satisfaction with their purchase. I will inform our Warranty Team of this review in case you would like to reach out.
