If you are not satisfied with a product purchased from the Site, you may request a return within 30 days from the delivery date, unless the product is listed under the Return Exceptions below or is subject to specific return conditions noted on the product page.

This return policy also applies, as a minimum standard, to products sold and fulfilled by third-party vendors through the Marketplace.

Please review the Return Conditions, Return Exceptions and the process on How to Request a Return Authorization (RA) before initiating a return request.

Returns under this policy concern non-defective products. In the case of a confirmed manufacturing defect, remedies are handled under the Warranty terms, at the Vendor's discretion. See the Warranty section.

Return Conditions

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

• A valid Return Authorization (RA) number must be obtained prior to returning the product. Returns without an RA number will be refused.
• The RA number is valid for 30 days. The returned item must be received within that period.
• 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.
