Description

The Shark PowerDetect Clean & Empty (IP3251) system is the ultimate cordless solution for powerful, intelligent, whole-home deep cleaning. It features an Auto-Empty system that charges & empties your vacuum after every clean and holds up to 45 days of dirt and debris. PowerDetect is powered by Shark’s most powerful cordless suction PLUS a redesigned DuoClean Detect nozzle with dirt- detecting intelligence and direction detect technology, making it THE BEST debris cleaning of ANY cordless vacuum.

PowerDetect has an impressive 70min of runtime and a MultiFlex wand for effortless under-furniture reach and flex storage.(Based on ASTM F558, measured at the hand vacuum, tested in Boost mode)(Based on Geomean of ASTM F2607, and IEC62885-2 (5.5) vs cordless market)( vs. original DuoClean nozzle)( vs. Shark Stratos IZ862H)( measured at the handvac in ECO mode)

    • Neighbor is jealous
Style: PowerDetect w/ AutoEmpty (Essential)
My third Shark. (This was not deliberate. It just happened...) First was a plug-in that I still use. That was when I met the fantastic maneuverable Shark head. Second was a cheap Shark cordless. It would only run for ~8 min at a time, and was not very powerful, but it sure did the job I hired it for! It still runs fine and has been passed on to others. I got this new one because it is Labrador Shedding Season (gasp!) and I needed something with more battery time and more power. The "auto charge/auto empty " stand feature is nice. I never minded emptying my smaller one, but plugging in the charger was a pain. Put this one on its stand and it charges. Nice. I did not realize this one came with the jointed "fit under the furniture" feature and would not have sought that out. And I was WRONG. This feature is GREAT! And so easy to use. HELPFUL HINT: Some folks report they cannot get the auto-empty feature to engage without a lot of banging around. With mine, once it is docked, I just tilt it back a tiny bit and voila! Second hint: Yes, I did manage to plug it up with black lab hair. But it was pretty easy to figure out how to open it and unplug. ... show more

    • Terrific Stick Vacuum
Style: PowerDetect w/ AutoEmpty (Essential)
Very pleased with this vacuum. So far, I only have pros, no cons. Here are the pros. * Excellent suction. * Very manuverable. * The detect feature is a great boon. I don't have to wonder if stuff on the floor or carpet has been picked up, the sweeper adjusts to get everything. I do watch the lights to know when all has been removed. * The dust bin empty feature is a wonderful addition. I prefer to empty a dust bin after each use but disliked doing that. Now, I hang the vac and presto, the bin is empty. It's not too heavy. * Given it's many features, I doubt it could be much lighter. * The battery lasts while I do everything I want to do. The battery lasts much longer than the other brand that's highly rated. Very pleased with the purchase. ... show more

    • Saved my cat-lady house!
Style: PowerDetect w/ AutoEmpty (Essential)
Things this vacuum WILL pick up: - Crystal cat litter - Timothy hay - Legos - Ruggable rug tops Basically this vacuum does everything I bought it for, specifically because the front cover clearance is high so it doesn't kick around cat litter, and somehow it pulls out rabbit's dropped Timothy hay through the hose better an even our normal upright could do. Better yet, it has a neat easy access to the curve point between the roller and the upright connection where a lot of clogs happen. My main complaint is that (since I am tall) this vacuum sometimes clicks back into its upright locked position while in use. It's a personal problem, no biggie. I do have to turn the suction down when going over area rugs, especially our Ruggable, but it gets everything out anyway. ... show more

    • It could be a 5 star but it's not.
Style: PowerDetect
I have used Shark products for decades. My last stick was a Shark Ion Duo that finally gave out. This one has some new improvements. I like the automatic carpet to floor adjustment and the edge detect. However it does have some issues: 1. It needs a edge detect on the front of the machine too. There are some areas that are on edges but you can't get the machines edges turned that direction to clean because there is no room. Like in the kitchen area if you have an "L" or "U" shaped kitchen. 2. It really does good on MOST carpets and hard surfaces. It does fine with my nubby commercial foot wipe mats at the front and back doors. It does not glide as easily over my plush dining room area rug as my old Shark did. It requires some pushing. It is absolutely horrible on my living room area rug. I have to vacuum in very particular directions depending where I am at on the rug. The rug is multi level. It is designed as squares with a low tuft "nubby" design in each one. Kind of resembling a tapestry. The squares are joined together with "stripes" of higher tuft plush carpet between the squares and surrounding the whole rug. My older Shark vacuum glided over it effortlessly on the "Carpet" setting no matter what direction I vacuumed. Not this one. If I am not vaccuming in the "correct" direction in a particular section of the carpet, it will not budge. I have to either pick it up and put forward of the section and then pull the vacuum backwards or go around my coffee table to the other side to move forward. There must just be a visually imperceptable difference in the tufts directionality or it just doesn't like the very frequent shift in height . Whatever the reason, that carpet is a PIA to vaccuum. Fortunately, for now, we found a replacement motor for the old one on Ebay. Should have done that first! The old one now works. If we had done that first, we wouldn't have needed the new one. :( 3. Shark is not fully supporting this unit yet. I wanted to buy an extra battery but it has yet to be in stock at Sharks website. Initially, I considered sending the unit back because of this. However, the battery lasts much longer than the Duo Cleans did. I had 3 for that one and I had 2 charging in it's special Duo charger and one in the vaccuum at all times. It did not charge while in the vacuum. With the new one, I plug it in while I am between rooms ( I dust, vac and mop one room at a time and then go to the next) and I have yet to run out of life. However, sooner or later that one will start charging less efficiently and then I will need a new one so it does bother me that I can't get one. Other accessories for this product are not in stock either. 4. The dirt collection unit removal latch is difficult to find as well as the latch to actually dump it. The instructions are not helpful. I know I could have purchased the fancy auto dirt dump unit that goes with it but I am not paying that much extra for a small convenience. 5. On my old Shark ION Duo, taking the head off to use the wand was a simple process. There was a nice little lever that you used your foot to press. Easy! On this new one, there is a depressable button that you have to use your hands for. This means laying the vacuum down on a high flat surface or stand it on the couch in order to press it. unless you have the strenght to hold it up with one hand and press with the other. Since the head would then fall to the floor, I don't reccomend that. Otherwise you have to prop it up with one hand and squat and press the button with the other. This feature has definitly regressed in functionality. NTM, my hand strength has decresed over the years (I am 72) due to arthritis and Carpal Tunnell surgery and the button is difficult for me to press hard enough to get the dang thing off. 6. On my old Duo, there was a nice handle just for lifting the thing to carry it from room to room. Not on the new one. This is a PIA if you have different levels. 7. Like my old Shark, once you remove the head you are lightless. I have solved this issue (on both old and new) by rigging up a Macgyver. I take a "pencil" flashlight and tape it to the wand with shipping tape wrapped around it and I just turn it on when I need it. It seems like Shark could create an integrated solution to this. Note to Shark, lots of cleaning gets done when it is dark. Surprise! 8. No Hair Wrap!!!! It lives up to this claim. I have hair past my shoulders and I seem to shed it all the time even though it never seems any thinner. On the old ION Duo, I had to clip the hair from the brush at least weekly and it was a royal PIA. The fact that this doesn't need it, partly makes up for some of it's other shortcomings. ... show more
