Huge Upgrade to my trusty V1 Robot
We've had one of the first model robot vacuums from the og manufacturer which has been a workhorse for us for years! It's the drunk uncle of robots though, no bells and whistles, just your basic robot that runs into everything but gets the job done in some random chaotic pattern. Seeing this on sale and finally just going for it to see how good newer models have gotten (no more separate virtual wall lazers, a nice easy to use app, no more bumping around clumsily!, and more). Well, long story short, they have gotten soooo much better and I'm incredibly glad I gave this one a try. It's is running flawlessly, cleans very well, i love the ease of the app and setting up no-go zones, and pretty much everything else has been an upgrade. Looking forward to many years of our new bot and a cleaner, less noisy, less drunk uncle of a bot around the house. (Don't worry, drunk uncle is still getting his time in down in the basement. He's old reliable at this point and will go as long as he wants to.) This is a great vac that performs wonderfully with all the functions and conveniences I need (i haven't tried the mopping function yet but didn't really buy it for that) at an incredible price point, esp when on sale. If you're looking to upgrade like I did, it's well worth it. If you're looking at your first robot and are unsure if it's something you really need.... trust me, get it. It will save you time, knock one thing off your million item to-do list, and will soon become something you are unsure why it took so long to try.

Updated Review: error code and quit working after only 3 weeks.
Update! I absolutely loved this vacuum.....for about 3 weeks. I ran it every day. I loved loved loved the mapping feature that allowed me to select which rooms of my house I wanted it to clean. It did a pretty good job and I was so happy with it. I took good care of it and cleaned the filter and emptied it often. It was great ...until it didn't work anymore. Fan error: error 155 called for me to factory reset the vacuum which I did 3 times but it still wouldn't go more than about 30 seconds before stopping and giving me the internal error code again. After researching the code (because the website and help book on the app don't list this code in their troubleshooting guide) apparently this is a common thing for this particular model (the Q5 pro) to do. And most of the time it isn't fixable. We were still within the time frame to return it through Amazon so we decided to do that rather than contact customer service in hopes that they might fix it but not and then not be able to return it anymore. Sadly I won't be buying this brand again for a while. My previous vacuum (roomba) lasted me 5 years and still works, just has old technology. I was really hoping for another vacuum with newer technology like house mapping to last me a long time as well. I most likely will be returning to the Roomba brand. Which is sad because this seemed like a great vacuum with great features for a good price. I hope roborock improves their models and fixes these error issues and maybe one day I'll give them a try again. Maybe.
Original review: I love this vacuum. I had another brand that was 5 year old technology and just caused more headache than help. This one is a huge improvement. I love how it initially mapped out my house and I was able to divide and name the rooms in the app. Now I can tell it to clean only certain rooms or the whole house and it does great and doing only the rooms I want it to do. I connected it to my Google speaker as well and now I can tell google to make my roborock clean my kitchen. I can also control it and monitor it from the app even when I'm not home. The mop feature isn't great. It really doesn't clean, more just puts water on the floor and leaves dirty streaks. But I didn't buy it for the mop function. If it does a great job vacuuming, which it does, I'm happy with it.

Works well!
If you have Omni S1 pro this is everything you could ever need to maintenance for it! I have it run twice every night and you can’t beat $60 to have several repairs several times! Totally worth its money and fits exactly as if bought new!
