I’ve had robot shark and roomba. I believe running them daily has prevented us from being buried in dog hair and 100% recommend a robot vacuum. My dogs are very housebroken and I’ve never had the poo every where situation.  Overall, I think the shark works a little better, but I think the roomba’s features and app are better. I just upgraded to the dual vacuum/mop roomba and it’s not perfect but I’m happy. I still have to real vacuum once a week as it doesn’t get all the hair all the time, but the literal basketball was of hair I pull out of the canister every few weeks tells me it’s working pretty damn good.

I’ve been seeing the roomba I-versions (i3, i7 etc) gently used on Facebook marketplace. It’s not perfect and some of the programming is annoying but for the most part it does a good job on our carpet with our dogs. I still run the real vacuum once a month or maybe every 2 weeks but the roomba helps a lot. I have one without the self empty so I’m looking to pick one up with it

The other commenters seem like theirs is quieter than the shark. We can have a conversation while it’s running which was a huge improvement over the roomba i3 we replaced. We have it run when we leave the house for the day so we are not usually watching tv while it goes

Bought a vac and mop roomba. I now that myself now maybe a month. I call my cleaning lady less frequently. So yes.

I bought the best roomba (mop and vacuum) on the market and I feel my floors and carpet being less dusty. Not saying you should buy an expensive one but consider the mop and vacuum combo

Your experience must be with the cheaper Roombas. I bought a $500 Roomba and base and my experience was the same as yours. Hot trash. Sent it back and even that was a bad experience, they never refunded me and I had to do a credit card charge back. But then I bought a $250 roborock + base. Wayyyyyy better. Never have to tinker with it. Completes our kitchen, dining room, main bedroom, and living room in 35-40 minutes. Does multiple floors/mapping. Vac and mop. A lot quieter than the Roomba. Very clean floors, like I'm blown away at how well it vacs, the Roomba left little crumb piles  everywhere. I have not manually vacuumed anything since I've bought it other than to spot clean when my dogs destroy a toy or something. Overall there is a reason irobot is going out of business. Roombas are overpriced and perform poorly. But not all robot vacuums are created equal and other brands are both cheaper and higher in quality.

We love ours. We have one for upstairs and downstairs. Don’t try to get a cheap one, we did that and went through a couple of them pretty quickly. Now we have two good ones (iRobot) with the bin that they self empty into when they get full. We have three kids, two dogs, and a cat that sheds more than both dogs combined, and having robot vacuums has been a game changer. Before we got the one with the bins, it would get full and need emptying before it finished a whole cycle. Now it goes and empties itself and then goes back to cleaning. It’s some trial and error at first. Just run it the first few times when you’re watching it to see where it has any problems. Then you can try to adjust any problem areas. Our upstairs vacuum doesn’t go into the bedrooms because the kids have lots of tiny Barbie shoes and stuff. We have them clean up good and just regular vacuum real quick every other week or so (and we keep bedroom doors closed so the pets don’t go in there to keep hair shedding out). But the robot keeps the main areas of the house from getting hairballs and dirty. We recently got a robot mop as well, and that has been awesome! I feel like it’s just like having any other vacuum. You have to get everything picked up off the floor before you start. You wouldn’t start regular vacuuming with things still on the floor. If there are areas that it gets stuck often, either block it off or try to adjust any problem areas. We usually pull all of the dining room chairs away from the table so that it can get a good clean under the table and around it. We run the vacuums & mop anytime we leave the house, and it’s so nice coming home to freshly vacuumed and mopped floors!

Read the reviews. I had a couple of Roombas that were very unreliable. A vacuum one and a mop one. Both broke after just a couple of months. I finally got a vacuum one on Amazon made by Eufy that got excellent reviews and it lasted for a couple of years until I moved and didn’t take it with me.

I bought a roomba i3 in 2020, and it's still working fine Every part is easily replaced, and there is lifetime support that I use once to replace the battery Although that was before it was bought by Amazon, I don't know if it's still the same

Oh! I didn't know It's still robust and serviceable, but yeah, parts might be hard to find soon
