So far so good. Seems to work well and pick up better than my other robot vac. Does a great job of returning to base and empty. Set up and mapping was easy and accurate.

A fantastic addition to our home! Wonderful to not have to run the vacuum cleaner daily. Now I have it setup to automatically do a morning routine. So incredibly helpful!

I love this vacuum! It works awesome and is a game changer for my busy family. I set her up and she cleans the entire house and then returns to her dock and I enjoy not having to manually vacuum every day after my dogs and children!

I bought this to replace my Shark that was about 6 years old. What a dramatic improvement! I loved time old but I’m blown away with this one! All the features and the ability to use an app with it!! Marvelous 💚

One of the he best robot vacuums I have bought. The mapping is great , and the self clean option is the best. This is my 4 th robot vacuum but my first Shark it’s safe to say I will stay with Shark.

This robot vac, I've named him Rover, works incredibly well and is a time saver. I love that I can schedule cleaning times and just let Rover do his thing. Great purchase!

I’ve tried to research replacement parts and even on sharks website it’s like this model doesn’t exist. The customer service was horrible. No how to videos. The filter in the vacuum itself is not replaceable and does not look like a reusable one that you can clean. It’s literally siliconed and molded to the dust bin so there is not way to take it out at all. I really want to love this vacuum as it does a good job cleaning but this is pretty much a deal breaker for me. Not being able to find any replacement brushes or even being able to replace the filter is a no go for me. If it’s a reusable filter I wouldn’t even be able able to know or find out as there is no info about this vacuum. I’ve got 3 dogs and I know that filter will eventually clog with dirt and will break the vacuum which is $400 down the drain. I will be returning this.

I purchased this vacuum in June when it had a rebate. Initially it was easy to set up, mapped my house well, and did a good job cleaning. However, after owning for only 2 months it started having issues. It was scheduled to clean every day. It would start to clean at scheduled time, but only cleaned for a few minutes and would then return to the base and never resumed. This happened every time after that. I cleaned everything and still had the same issue. No error message, just wouldn't clean more than 5 minutes. I deleted the robot from the app and tried to upload it again. Now it wouldn't even map my house anymore. It would leave it's base turn in a circle and then re dock when trying to remap the house. Was on with customer service multiple times in a day, but they weren't helpful at all. Luckily I was still within the return window for Sam's so I exchanged it for a new one without any issues. The new one started having the exact same issues a month into using it. I give up. I'm going to try to get my money back and buy a different brand.

I'd have given five stars except the unit was delivered without the side brush and contacting customer support to get one was very difficult. Like so many companies these days, Shark has done all they can to prevent you speaking or chatting with a human being. Side brushes are really inexpensive so I ordered some on-line, but a boomer like me expects all the parts to be included or we complain to the manager. So with that out of the way... I bought this to replace my Roomba S9 which was several years old. The Shark Matrix is much better at navigating obstacles like thresholds, furniture C-shaped supports, fabric on the floor and so on. I had to pretty much follow the Roomba around getting it unstuck, moving it off of thresholds, putting it back on its charger when it got lost and generally babysitting it whenever it was working. The Shark Matrix is much less labor intensive. While both can get tangled in wires, the Shark is far more forgiving. The Shark mapped my home a lot faster than the Roomba did. I have an area rug in my dining room with jet-black wide stripes. Both the Roomba and the Shark interpreted those stripes as "cliffs" they could fall into (and they both quit at those spots) so I will probably end up making that rug a no-go zone. The Shark self-emptying feature is excellent, though their claim that you only need to empty the dust reservoir every sixty days will only hold if you are vacuuming NASA clean rooms or hospital surgical suites. I cleaned my bedroom and bathroom once, which is less than a third of my house, and the dust reservoir was completely filled. And that after I had just used a stick vacuum on that room yesterday. We have a Golden Retriever dog, and they shed unbelievably much, so I'm sure most people will be able to go several days between emptying the dust bin, but I expect to empty mine every night. The flip side is that the vacuum was obviously picking up a LOT of dog hair that I had missed. In other words, it does a good job vacuuming the floor! The Shark Matrix is significantly less expensive than the Roomba S9+, but so far I am more pleased with the Shark Matrix. I recommend this product!

I'm giving this a 4 for right now because I've only had it for two days. Getting it on my network was a breeze, I then started a map of my house. It created the map but I can't tell what room is what. What I did is pick a room and tell it to go clean. Then I would see where it went and label the room. I couldn't decide between this and the Roomba I3 EVO and this, I decided on this because it doesn't need bags. It seems to clean very well. My rugs look great after a matrix clean. I'll update this review when I've had it a while.
