Comparing the Dyson V12 and the Dyson V15
Dyson is well known for its powerful, innovative vacuums, offering even cordless models that can deep clean all surfaces. The V12 Detect Slim and V15 Detect are two of the brand’s more exciting models because they both feature a dirt-revealing laser that illuminates hidden dust and debris to thoroughly clean hard flooring.
The similarities between the Dyson V12 and Dyson V15 don’t end there, though. They also have similar run times, offer the same cleaning modes, and come with the same tools to increase their versatility. Both models have an LCD display, too, which provides info about the particles you’re picking up.
But there are some key differences between the two. The V15 Detect gets the edge when it comes to overall suction power, while the V12 Detect Slim has a slimmer, lighter design that makes it more comfortable to use.
So, while both the V12 Detect Slim and V15 Detect are top-of-the-line cordless vacuums, they excel in different situations. Ultimately, the Dyson V12 is the better option for anyone who wants a lightweight vacuum that’s easy to carry from room to room or up and down stairs. On the other hand, the Dyson V15 is the clear winner for deep cleaning or homes with plenty of carpeting.
Spring cleaning can be a tedious, time-consuming chore if you’re not equipped with the right tools. These top-tested products from BestReviews can help you get your home sparkling clean in no time at all.
Dyson V12 Detect Slim vs. Dyson V15 Detect specs

With its lightweight design and single-button power control, the Dyson V12 Detect Slim is certified by United States Ergonomics, an organization that tests products to determine how difficult they are to use.
Product Specifications: Run Time: Up to 60 minutes | Suction Power: 150 AW | Bin Capacity: 0.09 gal | Weight: 5.22 lb
As its name implies, the Dyson V12 Detect Slim is a compact, lightweight vacuum, weighing just over 5 pounds. In fact, it was one of the lightest cordless models we tested. As a result, it was very easy to maneuver around furniture and other obstacles. We were very impressed with how easy it was to move around our testing area, especially up and down stairs. It also has a maximum suction power of 150 air watts (AW), allowing it to clean effectively on both hard flooring and carpeting. However, its max suction isn’t as powerful as models like the Dyson V15, so it sometimes required two passes to pick up debris on medium-pile carpeting.
Because the V12 Detect Slim has such a trim design, though, its dustbin is smaller than those found in other cordless vacuums, so it needed to be emptied more often during testing than models like the V15 Detect. Dyson advertises a run time of up to 60 minutes for the V12 Detect Slim, which is similar to other Dyson cordless vacuums, including the V15 Detect. However, during our testing, the V12 cleaned for 54 minutes in Eco mode before its battery ran out, while the V15 cleaned for over 60 minutes.

The testing team was impressed by the Dyson V15 Detect’s powerful suction.
Product Specifications: Run Time: Up to 60 minutes | Suction Power: 240 AW | Bin Capacity: 0.2 gal | Weight: 6.83 lb
The Dyson V15 Detect is one of Dyson’s most powerful cordless vacuums, and that power means a heavier design. It weighs nearly 7 pounds, over 1.6 pounds more than the lightweight V12 Detect Slim. It wasn’t difficult to move around our testing area, but we found that our arm often got tired when cleaning for longer periods due to its weight. However, the V15’s larger build allows its dustbin to hold more than double the V12 Detect Slim, so we didn’t have to empty it too often during cleaning.
