When is Black Friday? This year, Black Friday is happening on Friday, Nov. 28, while Cyber Monday will be on Monday, Dec. 1. Black Friday is always the day after Thanksgiving in the US, a holiday that is celebrated on the last Thursday in November. Many employers have historically given workers the Friday after Thanksgiving as a day off, so retailers started featuring discounts to encourage people to do their holiday shopping. Are robot vacuums really cheaper during Black Friday? Yes, robot vacuums really are cheaper during Black Friday and Cyber Monday. Cyber Week is the last big shopping event before the holidays and also the last one of the year, so many retailers offer steep discounts on their stock to prepare for the new products that will launch in the new year. How did we choose these early Black Friday deals? I constantly monitor robot vacuum deals as part of my work, so I'm always looking for the best discounts that offer the best combination of features and value. As a robot vacuum reviewer, I've tested dozens of models across different brands and every price range -- so I've become very well acquainted with robot vacuums, their features, and their worth. Through this experience, I've realized that the robot vacuum market is currently saturated, and many brands attempt to outcompete one another with significant discounts during shopping events.
