Great robot vacuum, but suction sucks. I have a dog and this vacuum was only picking up 50% of the hair from my carpet. Definitely performed better than Roomba J7, but not even close to Neato D9 I got instead.

It maps perfectly, and ran great for a couple of weeks. Then error #2 became constant. The front brushes would continually stop working. It was also very frustrating every time the wifi would disconnect.

Great robot vacuum for tile, wood, or hard surface. Not great for long carpet or pet fur on carpet. The battery lasts about 30 mins and needs to be recharged. Does not go off ledges or stairs and has great sensors.

Admittedly I should have done a deeper dive before purchasing this expensive robot vacuum. I wanted a self-emptying robot and thought Shark had a good reputation. Now I know the robot has a common problem - Error #2. Looking at several "fixes" and work-arounds, I find different causes for this error. Another issue I have is it sometimes just stops and I have to carry it to the base. Very frustrating. I had a great experience with the Eufy and will purchase that brand next time -- never again for a Shark.

Got a new wifi network in the house and put my robot out of service. No instructions online on changing network information. Called the Shark company just to get some help and all they want to do is data mine. Asked me all kinds of questions that were completely irrelevant to my problem. Finally got fed up and just got right to the point, "how do I get this connected?". He tells me to delete the ronot from the app and start a new one, except that's not working either. I don't need to be put on a sales call list or email blast, just help me fix my problem. I'm just about ready to toss this thing in the trash.

After trying to have it map the house 5 times, I finally just gave up and accepted "good enough", even though it's not detecting a wall between two rooms.Although I tell it to clean a specific room, it'll still wander outside of it.When I have it clean the whole house, it'll revisit the same room multiple times instead of going in once, cleaning it and not returningIt doesn't pick up all the dog fur, but it does pick up most.It's pretty loud compared to other robotic vacuums I've tried.I wish it did everything it advertises but it just doesn't, though it does do barely enough to not return it. Definitely, absolutely not worth the price.

The WiFi will "constantly" (about every two weeks or so) disconnect then seemingly never try to connect again. I'm required to physically turn it off and on again, which kind of defeats the purpose of being connected to the internet. It also seems to not remember the cleaning schedule if the WiFi didn't work, so your floors get dirty again, or in our case dog hair builds up again.As a vacuum cleaner it does better than my older Roomba which just bounced around the rooms never really getting everything. This goes in a somewhat orderly fashion. Though I wish it would finish a room instead of bouncing back afterwards to get the spots it missed.

Though it cleans thoroughly, I’ve had too many instances of having to troubleshoot. The problem that occurs most often is the shark becoming disconnected from our WiFi which involves several steps and lots of waiting in order to get it back online. That problem seems to arise about once a month. The other problem is that it will randomly turn on in the middle of the night and begin running in a random pattern in our house, banging around hitting walls and furniture. My family and I wake up to what sounds like an intruder and it’s pretty disruptive. I wish it wasn’t so problematic but at this point it’s quicker and simpler for me to just use our cordless vacuum and clean the floors myself.

I find that I am getting a dust bin or debris error every other time it runs. It also needs the roller to be removed to clean out hair wrapped around it about once a week. I have it scheduled to run every night so it really isn't that dirty in between.For the same $$ I would buy a Roomba.

I was extremely happy with my shark ninja robot vacuum cleaner received on November 29th 2022. It’s cleaning and mapping abilities was extremely impressive. I only used this device every 3-4 days. I February 20th I turned on the vacuum and all it did was spin around and around. I changed all the parts I could fined per manual of device which was very limited in instructions of where the filters were and how to change them. I blew out with an air device the sensors with no change in the vacuum device going round and round with having no direction. I call the helpline whom looked at the issue and is sending me new robot vacuum cleaner. They were very helpful but now I wonder is this going to be an on going issue and with the new one, I have no insurance on it but the one year warranty.
