Return Conditions
To qualify for a refund under the 30-day return policy, all of the following conditions must be met:

The RA number must be included with the return.
Products must be returned in unused, unmodified condition (e.g., no scratches, alterations, missing parts, or signs of installation/use) and in their original packaging, suitable for resale.
Shipping fees are non-refundable. Return shipping costs are the responsibility of the customer, except in cases of a product confirmed defective through RobotShop's troubleshooting process or of a verified shipping error by RobotShop.
Refunds are processed within 7 days after receipt and inspection of the returned item.
A €100 cleaning fee may apply to domestic robots returned in used or unclean condition.

Used, damaged, or modified products — Items that show signs of use, wear, or alteration, making them unsuitable for resale.
