Customer Reviews for Dyson - V9 Submarine Extra Dry Cordless Wet and Dry Stick Vacuum - Dark Gray

I bought this specifically for the submarine attachment because I already have a V15 that I'm really happy with. The build quality on the submarine attachment is very poor compared to standard Dyson attachments and it took me some time to assemble it for use after first disassembling it while clean and dry for practice. The actual mopping function was excellent. Cleaning the submarine head was easy as well. However, once it dried, I was completely unable to assemble it again. The pieces just didn't fit together. I had already spent several fruitless hours with Dyson's offshore support trying to get clarity on what parts were supposed to be included on the box and decided to return the entire thing. If you wanted this only for vacuuming, it is likely a great device but the poor design of the mop attachment made it useless for me.

The vacuum is okay. It is convenient and light weight but the trigger needs to be engaged the whole time and my finger gets tired. The part I dislike the most is removing the dirt/dog hair from the canister. I try to shake it but the debris never comes out without me reaching in and pulling it out. I might end up going back to a broom and dustpan. I just expected more thoughtful details.
No, I would not recommend this to a friend.

Bought this V9 to replace an older V7 model: better vacuuming and maneuverability! Works very well on both carpet and hardwood. Even used it on the bedspread to remove lint. Easy to clean. The HEPA filter and the time usage/count down feature are pluses. Has similar attachments as both the V7 and V8. That being said, it is unfortunate the attachments from previous Dyson’s do not fit and the V9 uses a different docking/charging station. It would be helpful to know how to responsibly recycle/repurpose these unusable pieces.

This is our 3rd version of this vacuum and I love it. I don't love that the capacity of the canister has gotten progressively smaller. We have two dogs (lots of dirt and hair) and have to empty the canister 3-4 times every time we vacuum the house.

I was very surprised how lightweight the vacuum is. It has a powerful suction and the battery lasts quite a long time. It moves in small areas easily and under cabinets. I mostly use it on hardwood and tile in on the main floor of our house. It works well on rugs if they are thick. The thinner washable rugs it is much harder to use since the suction is so good. Overall, I am enjoying the stick Vac.
