I suggest the V12 Detect Slim to just about anyone who asks for a cordless vacuum recommendation because it's the cheapest Dyson vacuum with the green laser. If you're not yet a laser believe while reading this, I'm fully convinced that you will be the first time you shine it on a corner of your floor that looked debris-less otherwise. The laser highlights invisible hairs and tiny specks of dust that even the LED lights on other cordless vacuums I've tested don't pick up on.
Take the area around the litter box in my kitchen, for example. I use wheat or grass kitty litter (for sustainability reasons), which is tan and completely blends in with the hardwood. You can barely ever tell that there's tracked litter on the floor until you walk past it in bare feet.
The most satisfying part is the visible proof that the V12 Detect Slim actually cleared the floor of debris. I even use it to see how well all of the robot vacuums I test are performing.
Even though the V11's suction power is ever so slightly stronger, there's much more to be said for such blatant direction to the spots in your home that aren't as clean as you thought they were. Plus, the V12 Detect Slim comes with two full-sized cleaning heads, while the V11's single Motor Bar cleaning head may not be as gentle on delicate hardwood or tile. Both offer around an hour of battery life on one charge and come with the mini motorized handheld attachment.
