Most robot warranties are written for the person who bought the robot new, and several say outright that they cannot be transferred. Roborock, Shark, and Worx say so. Ecovacs warrants the “original purchaser.” iRobot, Navimow, Mammotion, and eufy tie coverage to the original purchase, but the terms we read do not say whether a second owner is covered. If you are buying or selling a used robot, assume the warranty does not come with it until the maker says otherwise in writing.
Last reviewed: October 2026. This is a plain-language read of each maker’s published terms. I am not a lawyer, and this is not legal advice. Only the maker can say whether a specific claim would be accepted.
What each maker’s terms say
- Roborock: its US warranty says it cannot be assigned or transferred, and that Roborock’s obligations are only to the buyer. A separate six-month warranty covers certified refurbished units sold by Roborock.
- Shark: the SharkNinja warranty we read says coverage applies to the original owner and the original product only and is not transferable. It also requires purchase from an authorized retailer.
- Worx: its 3-year warranty says it applies only to the original purchaser and may not be transferred.
- Ecovacs: its US warranty is given to “you, the original purchaser” for new products bought and used in the US and Canada. It does not say whether a later owner is covered. It does not warrant products not bought from Ecovacs or its dealers. Certified refurbished units have their own, shorter warranty.
- iRobot: the warranty copy we read applies to robots bought from iRobot.com or an authorized retailer and asks for the original proof of purchase. It does not say whether it transfers.
- Navimow: the warranty runs from the original purchase or activation date and requires the product to be bought from Navimow or an authorized dealer. It does not address a second owner.
- Mammotion: the warranty period starts at the first purchase, and a claim needs proof of purchase with the date and the serial number. Labels or serial numbers that are changed, removed, or illegible are excluded. The page does not address a second owner.
- eufy: the warranty runs from the original purchase date and is valid only in the country of original purchase. The page does not address a second owner and tells readers to contact eufy to verify the terms for a specific product.
- Husqvarna Automower: we did not find transfer wording on the pages we read, so we cannot say.
We did not check pool cleaner makers for this page.
If you are buying a used robot
- Ask the seller for the original receipt and the serial number. Several makers want both for a claim.
- Ask the maker in writing whether the warranty covers a second owner, and name the model and serial number.
- Check where the seller bought it. Several warranties require an authorized retailer or the maker’s own store.
- Check the battery’s age. Many makers treat batteries as consumable parts, so a used robot may need a new one soon. See battery replacement cost.
- Compare the price with a new or certified refurbished robot from the maker, which comes with its own warranty.
If you are selling a robot
- Say plainly whether you expect any warranty to remain, and pass along the receipt and serial number.
- Reset the robot and sign out of your app account before handing it over. Steps vary by maker, and a reset can erase maps and schedules.
- Do not promise coverage you cannot confirm.
Check what is left on your own warranty
Use the warranty checker to see when your own coverage ends, and warranties compared for length and battery coverage by brand.
Frequently asked questions
Does a Roomba warranty transfer to a new owner?
The iRobot warranty copy we read does not say. It applies to robots bought from iRobot.com or an authorized retailer, and it asks for the original proof of purchase. Ask iRobot before you rely on it.
Can I transfer a Roborock warranty?
No. Roborock’s US warranty says it cannot be assigned or transferred.
Does the warranty cover a robot I bought from a private seller?
Often not. Several warranties require an authorized seller, and some name the original purchaser. Ask the maker in writing.
