Wow! Not always easily impressed!

I just bought my Shark Duo Power Detect vacuum this morning. I came home and immediately went to work cleaning the area rug in my sunroom which had been vacuumed by my previous machine two days prior. I expected to see some residual dirt, especially since I have small dogs. What I did not expect were the results demonstrated in the photos below! I photographed the results after vacuuming once, then twice, then 3 times over the same rug! Needless to say, I am quite impressed. The machine is heavier than other vacs I have used, but for these results I will happily accept the trade-off! When I say this vacuum sucks, I mean it in the best way possible!

Never going back to the “other” guy

I was a creature of habit and once I found something that worked I stayed with it and that was me and another popular vacuum. I also became a loyal ninja consumer once I bought my first blender about 17 years ago. I did dabble with shark when the steam cleaner came out, I still own, and use, the handheld purple one from years ago. But this is my first experience with shark vacuum cleaner and I can't believe I waited so long! All of the features go beyond what I thought I needed, until this vacuum showed me I definitely did need! 1. The lights in the front showed every hair my furry friends leave on the hardwood floors. 2. My lower back didn't hurt after using this vacuum, I didn't have to twist and pull to get it to go the way I wanted, unlike the ball that ruined another brand. 3. Let me tell you about the odor neutralizer, WOW!! Even the cleanest dogs leave a “dog” smell in your vacuum and blow it back at you as you clean. Not with this vacuum, my home smells so fresh after vacuuming! 4. On the hardwood floors I loved how well it picked up the gritty bits my dogs bring in without spitting it back out at me 5. No bending over to switch from carpet to hardwood floors, this smart one knows what to do 6. The attachments are great and the best part is the lift off, no more carrying a heavy vacuum up the stairs 7. If you use attachments without liftoff I didn't have the vacuum follow closely and trip me up, the hose is much more flexible but not flimsy by any measure! I know there are more things that I'm missing for right now but I think everyone should know I'm giving this vacuum 5 stars! Other brands, I think, have become complacent and just moved on from their vacuum once they perfected it. Not shark, they perfected and made it so amazing. They truly were listening to their customers and went above and beyond!

Not good for dog hair

I have numerous shark products. Including 7 total vacuums (2 robots). This does not count the other appliances including 2 coffee makers, an air purifier, handheld mixer, blender and the ninja creami. I am sure I am missing something. Out of my countless vacuums this one is by far the worst one that I have had for pets. I had the previous model (which I still have and use) for pets that seems to work better than this one. My husband purchased this one for me for Christmas in 2024. I started using it about 8 months ago. I wanted to continue to use it before leaving a review. I have 2 German Shepards and I vacuum every day. I have to take off the roller at least one time during my daily vacuum to suck the hair off of the "comb" portion behind the roller. I have never had this issue with any of my other shark products.
