## Description

The PowerDetect robot vacuum is powered by 3 deep-cleaning technologies that enable the robot to maximize performance by sensing mess level, floor type, and edges & corners. DirtDetect sees even the hidden debris and automatically increases suction and cleaning passes to remove the mess on carpets and hardfloors. The only robot with NeverStuck technology, it will navigate around obstacles AND lift itself up and over thresholds and onto thick carpets. Not only can the robot deep clean, but you also do not have to worry about it getting stuck. PowerDetect finishes the cleaning mission every time and with each clean will empty itself into its bagless base that contains a HEPA Anti-Allergen Seal trapping dust & allergens inside.

Review: Freegin Awesome (Boxer Dog Owner)! - So my first robot vacuum was an original iRobot Roomba many years ago prior to this auto-dump tech. I loved that thing and it still works to this day, however obviously its nearly daily use maintenance was too much for me to do each time. FFWD to now: I live alone with a boxer dog and am gone to work each day so my home's floor was just too much for me to be able to maintain. I decided to invest in a new tech auto-dump technology robotic vac, which would be perfect. Nutshell: after much research and my great experience with iRobot, I decided to order up their latest and greatest, and at "greatest" cost. Supply chain issues delayed delivery for a month, okay, got that. After a month, emailed company just to simply get an update. Did this four or so times over the following month. I received zero, absolutely zero responses, to my utter surprise. Placed two phone calls in to their customer service, and each time after on hold for 45 minutes, I gave up. I was willing to wait - but.... Their product originated in development from the USA, by higher ed students originally afterall. Wellll, suffice it to say I experienced the outsourcing effects of their company. To cancel, I ended up having to go to the lengths of changing my credit card number, updating auto-charges from other providers on that account and it was THEN that I FINALLY heard back from iRobot. Who would want to invest $1300 in a device with zero company customer service response after 4-6 or so tries? Not me. So saddened to see yet another great company to sail off our lands. So I decided to give Shark a try at half the price-I have some of their appliances which have been great. First delivery didn't go well, and that's because I didn't pay attention to the exact model AND the seller. It arrived, I set it up, and the battery would not take a charge. Turns out it was a "previous" model - obviously had sat on some shelf for who knows how long. Returned, and desertcart covered my back on this. More research showed me that that unit wasn't the current model. I decided to order this one which at this time is the CURRENT model, and sold THROUGH desertcart, fully returnable. I can not say enough about this little critter! It's just amazing! This robot vac has made a huge difference to my home. I don't really understand the other reviews' complaints about it's vacumming "noise" be it while operating or on its base in sucking out the bin. It's absolutely no louder than my wired Dyson unit while "sounding like an airplane taking off," for all of less than 10 seconds. To me, the freegin louder it is, the better it's cleaning out the robot! I launched it without even preemptively vacuuming my home- it worked hard and it took a few good cleaning out's to get it more leveled out and that's on me. I made a few changes to my home physically and reset its map by deleting the map (put my couch up on hockey pucks for access-it's about 3.5" tall). It's now re-learning my home and doing a fantastic job after several runs! I can add "high traffic 'rooms' " or areas layed over the top of overall rooms. Contrary to other reviews I've read, probably earlier ones, you can add rooms and name them to your use- I've overlayed "rooms" over larger "rooms." I love this thing! I can't believe it's only been a month of use - I've used the crap out of this thing. No issues and very adaptable. The only thing I look forward to is to be able to program more than one program. You can currently program one session- per day, per week, every each day of your choice, but of your selection of rooms identified including all of the rooms. Can't do an additional sub program of, say, "high traffic areas," which I've added as additional "rooms." I've read that is coming in future software updates. iOS WiFi connectivity is great. Map views when swiping give you more than one historical map of effected coverage. At half the price, "customer service" response remains to be seen (I've not had to), I would recommend this unit. Just make sure you look at current models, and not the older very similar looking models. As with any robotic vac, I'd recommend a home, or shop-use air compressor with regulated output to soften as needed for blowing out all as needed. I also found some great video reviews online that taught me a lot about this model line- very similar responses. By design, one can tell older vs newer units simply by how its dump cannister is designed. The map image I am attaching is one of its first runs of learning, and you can see it did a really good job of coverage for its first attempt. Smaller home in my case but numerous areas-after which I edited rooms, areas and overlayed high traffic areas as additional rooms for double-cleaning. It's been great once my home floor condistions leveled out and the robot can easily cover all areas. Not hard at all- give it a whirl! Hope this helps some. r-
Review: Does the job just fine! I would buy again. - So far, so good. Works as described. I have three dogs ( short-to mid length hair, mastiffs ) and bought this robot to keep the dog hair under control. I did an initial deep vacuum with my upright vacuum (also a shark, highly recommend) and started with the robot the next morning. I run the robot every morning. The robot connects to wifi without any problems. It mapped the area that I intend to use it for. I move any objects that may be in the way, such as bar stools, dog beds, and such. The robot does its thing without any problems. I have bare floors and low profile area rugs. It returns to the dock to empty and resumed its work. I am very happy with the performance. I empty the bin, wipe off the robot with a microfiber cloth after each use to keep it dust free, and it's quick and easy. The only problem that has come about so far, was a piece of wood splinter, from the dog chewing a stick it snuck in the house, stuck in the robot in the space that connects to the base and caused it to not empty but the app let me know there was an issue and I was able to clear it simply with my finger and all was well. It takes about an hour for the robot to clean the area it is mapped for (about 500 sqr. ft around obstacles). The battery still has about 60- 70% of power left when finished. It is new, so I will do an update if that should change. It does not hit or smash into furniture like some of the reviews that I read had said, it was gentle, in my opinion. I have always had great results from all my shark or ninja products. True story.

### ⭐⭐⭐⭐ Good robot vacuum, could be improved.
*by M***N on July 21, 2026*

Long Informational/personal experience review for Shark Stratos 2 in 1 vac mop with power detect. Overall, this vacuum has made maintenance cleaning easier to keep up with. BUT, I would just recommend doing a bit more research on the programming quirks, software nitty gritty type things. I dont like that if I move furniture in one room I cannot just change the map in that room, I have to delete the entire map of my house and let it remap the house for 30 minutes. I also dont like that this model will run anything over if it isn't over 3 inches tall. For example, my dining room table has legs that are connected by a steel bar that runs along the floor (like an old school lawn chair) and the vacuum will run over that bar back and forth dinging up the bottom of it. I also dont like that the mop reservoir does not completely empty back into the base when it is done mopping so it always has a bit of watter sloshing around. Another mopping quirk I dont like is that when its done mopping, for instance mopping the bathroom or entryway, it will then keep the dirty mop pad down leaving a snail trail for dirty mop pad water alllll the way across the house when it goes back to the base. Bathroom & entryway germs spread all across the house. And then there the software bug or default issues. Like recently I have noticed that my robot will be told to clean a spot in the living room, then 10 minutes late I realize that it never did it because it got lost going from the dining room to the living room (a 15 foot journey) and had been going in circles the whole time. It has been doing this quite often, starting about 6 months after getting it. It started with the minor detour then correcting itself, then it turned into it being found on the opposite side of the house when I asked it to vacuum the entryway. Like I said, I didn't expect a perfect robot and it has made things easier, but the annoyances should not be there if I am paying over six hundred dollars for a vacuum. The app is pretty easy to use. Works well on hard wood, tile, and low pile carpet. Works on medium pile carpet too, just now as well. Does pick up hair but it gets caught in the brush and needs to be cut out every so often or it will not vacuum good. Also, it ran over a dryer sheet one time and it got stuck behind the wheel up inside and started running in circles, so I would check that often.
