The Tineco Pure One S12 is one of the most unique cordless vacuums we've ever tested. It has a user interface that lets you know how much battery life you have left, the amount of suction, and how clean your floor is.

While testing, we found that the S12 was pretty good at estimating how much dirt was on our carpet. It declared a clean surface when 80% of the testing dirt was suctioned up. Overall, the cleaning performance lagged behind other cordless vacuums in the Pure One's price range, but not so much so that it's a deal breaker.

If you want the coolest tech in your home, the Tineco Pure One S12 is a solid choice.
