Product Reviews of Dyson V9 Submarine Cordless Vacuum

Overall Rating Snapshot

Fantastic cleaner and washer
We recently upgraded our elderly dyson for the new v9 submarine. We are absolutely delighted with the new machine. The vacuum cleaner is lightweight and works perfectly. Changing to the washing function is quick and easy and on our vinyl plank floors the result is way better than we expected (so much better than a mop and bucket) .Overall we are very happy with our purchase and would not hesitate to recommend it to anyone else.

Absolutely Love Our Dyson V9 Submarine!
We received the Dyson V9 Submarine Cordless Vacuum as a gift from our family, and it’s been amazing! It cleans both wet and dry messes effortlessly, and the cordless design makes it super convenient. Floors have never looked this good — absolutely love it!
