I’ve been able to use the Shark Detect Pro Cordless Stick Vacuum for the better part of a week and I’m very impressed overall. I’ve been fortunate to own various stick vacs over the years from many manufacturers, and I wanted to just highlight what I really love about Shark’s take on the smart vacuum. First, Shark advertises their newest stick vac as the QuadClean machine. There are four selling points to this vacuum: (1) It will automatically adjusts power based on floor type (hard vs carpet); (2) it will automatically increase suction power when vacuuming along baseboards; (3) it has a row of LED lights to shine your path to allow you see dirt clearer; (4) DirtDetect that will automatically boost suction power when there is a higher level of dirt detected. (1), (2) and (4) are definitely testaments to its attempt at automation, and it actually does these very well. I have a mix of hardfloor and area rugs, and the Detect Pro has no problem switching power levels between floor types. It is actually very good at shaggy rugs and unlike my other stick vacuums, it doesn’t bog itself down. The cleaning head is a mixture of microfiber and hard edge bristles to satisfy both floor types. I have various low and high pile rugs and the Shark had no problems transitioning at all. The head height is relatively low and I can get it to fit underneath all of my couches. When vacuuming along baseboards, the vacuum will change its runway LEDs to only illuminate half of those closer to the wall and amp the power up to assist in collecting dirt and dust that had accumulated in those tight corners. When vacuuming over dirtier areas, the Detect Pro indicator will change colors to illustrate the amount of dirt detected, indicating that you should probably vacuum that spot just a little bit more. Red (dirty), Orange (less dirty) and Blue (clean) are your color indicators and they appear on the main unit as well as the floor cleaner head. As far as the “tale of the tape”, the Detect Pro is about 6 pounds, can hold about a tenth of a gallon of dirt and debris. Its cleaning path is about 11 inches. It’s a 15 AMP 240W system, with a charge time of about 3 hours and a maximum runtime of 40 minutes. As expected with most stick vacs, it is equipped with a HEPA filter. Does the Shark Detect Pro have suction power? Absolutely. After a few runs at home, the dirt collected was a clear indication that this machine is working. I generally keep my floors clean and it is still able to pick up dirt that I was not able to see. Speaking of seeing dirt, the one thing I truly appreciated about the cleaning head is the runway LEDs across the front of it. It’s very reminiscent of the corded vacuums with the running light. You can actually see dirt in those dark areas of your house like underneath tables, chairs and the like. It’s actually quite satisfying to see and pick up that dirt that you wouldn’t have originally seen. Since it is low power LEDs, I think the Shark engineers could afford to squeeze a tiny bit of battery power for its purpose. One other huge benefit is its ability to self clean its roller head. If you live at home with folks that have long hair, you know how hairlicious the roller heads can get on vacuums. This self cleaning head will actually get rid of the tangled hair. Nice. Battery life is advertised as 40 minutes; this is assuming you run the machine in a lower power setting from start to finish. So if you’re an all hard floor household, you will definitely benefit the most in terms of runtime. For the rest of us who have a combo hard/carpet flooring, you’ll probably squeeze 20-25 minutes. For all-carpet folks, you’d be better off running a corded machine because the Shark would automatically boost power to satisfy carpet cleaning, severely cutting your runtime. Now all these runtimes definitely depend on the size of your home. For me, living in a 2400 square foot home the Shark was able to tackle all of it in one pass. Bin size is a tenth of a gallon, or about one 12oz glass of water if you want to think of it that way. Conventional wisdom says to empty out the bin after every use, and you’ll probably have to do so with a bin this small. But I didn’t find myself emptying the bin midway though my cleaning. So, I do have ONE gripe with this machine, and it's the floor cleaning head and its ability to lock itself in a rest position. When not in use, the head’s neck locks into place to keep it standing upright. When vacuuming in tight spaces, I’ve inadvertently locked the head in this upright position without knowing…and the result is me vacuuming the floors thinking that the roller is making contact with the ground when in fact it is not. It doesn’t take long for me to realize it, but man it is quite annoying. I don’t have to worry about this with other stick vacuums I own, so I had to dock a star off for that. Another honorable mention: storage. For the life of me, I cannot get this thing to stand up against a wall when the roller is on a hard floor. On carpet, it’s fine as the carpet is enough to keep the floor head from rolling away from itself. Overall, I find this vacuum to be very well worth the price, considering its competitors are about double the price. Worried about quality?? The Shark Detect Pro Cordless Stick Vacuum comes with a 5 year manufacturer’s warranty on both parts and labor.
