Refurbished robot vacuums are the same machine for less money

A refurbished robot vacuum isn’t someone else’s junk — it’s a returned or open-box unit that’s been inspected, repaired if needed, thoroughly cleaned, and tested before being resold at a discount. The manufacturer or a certified company replaces worn parts and repackages it, so you’re basically getting a like-new machine for less. Just check the warranty before you buy.
