The iRobot Roomba 415X, a combination vacuum and mop robot, is currently discounted 50%, bringing its price under $400 ahead of Amazon’s Prime Big Deal Days sale.
The sale price is temporary and tied to the run-up to October Prime Day, which runs Tuesday, Oct. 6 through Wednesday, Oct. 7, 2026.
The Roomba 415X has a slimmer design than earlier iRobot models, allowing it to fit under furniture for more thorough cleaning. It uses tangle-free rubber brushes designed to handle pet hair, and it applies extra pressure when it detects dried stains in an effort to remove them without manual scrubbing.
The device also handles its own maintenance. It returns to its dock automatically after cleaning, and the dock includes an auto-wash feature for the mop component. Owners only need to empty the dock about once every 90 days.
What Is Prime Big Deal Days?
Prime Big Deal Days, also referred to as October Prime Day, is Amazon’s major fall sales event, held annually ahead of Black Friday and Cyber Monday. It differs from the July Prime Day event in that it runs every October, giving shoppers an earlier start on holiday purchases.
Access to Prime Big Deal Days discounts requires an Amazon Prime membership. Shoppers who are not already members can sign up for a 30-day free trial to gain access to the sale and other Prime benefits, including free shipping.
Amazon’s next full Prime Day event is expected in summer 2027, though additional deals are anticipated around Black Friday and Cyber Monday later this year.
