Most robotic vacs are great, especially if you don't have wall to wall carpeting. I have a Robovac and an Eufy.

I love it. It keeps our house clean and works every day so I don’t have to. We have an Ecovac Deebot XI Omni. It also mops and you can tell it what to do verbally with standard commands like “Go back to base.” Now that I have had one for 3 years I would never go back to manually vacuuming. We have carpet and tile. Our version also has the pet poo interface that you can turn on if you have pets that have accidents in the house on occasion. It recognizes it and steers around it.

I’ve had two roborocks for five years…two houses. Both have performed flawlessly.
My model is pre-mopping. After the first few runs you know where it will get hung up. I just drop a throw pillow in that spot and Timmy bounces off the pillow and moves on.
Now I’m looking for a robot to change sheets and clean windows.

Now we know who the lazy one is in your house. LOL

We have had a EUFY for years. Love that it cleans under the beds and along the edges.

We’ve had a Roomba for about 10 years, still going strong.

You wouldn't say that if you knew how hard it is to supervise my wife.
It's easier herding cats!

Our friends' EUFY flat out quit on them after two years of daily use. Ours didn't even make it that long, not daily use and not being here 6 months of the year.
It constantly got hung up in wires, stuck among chair legs under the dining room table and bar stools. I had to block the elderly dog off because he wasn't afraid of it, and it would vacuum all around him and eat his tail. His hair got caught in parts of it, requiring lots of disassembly. Making a 14-year-old 85-lb arthritic dog move from room to room was more than I was willing to do to him. So I had to stack things around him, which was more work for me.

I got tired of having to get all the chairs and stools up off of the floor and untangling the thing from wires, freeing it from all the places it got caught.
It also vacuumed randomly, which I didn't like, but possibly I could have corrected that online had I ever been able to get it to connect to our wifi. (And I'm not tech-challenged.)

When it quit on me I went back to our trusty cordless Dyson Animal Stick.

Make sure you get the one that has a memory so that it memorizes your floor plan. It must be programmable for that. We have one that isn't and so it constantly goes around with no rhyme or reason and duplicates where it goes. It also gets hung up on areas easily such as where the sliding glass door lower frames are located. Goes behind chairs and cannot find it's way back out. Things like that are annoying.

I wonder...how many guys here have said that to their wife?

:D

Samsung and iLife mopper
 

20 years user and contributor to robotreviews.com with engineering info, repairing bots etc. I prefer the Samsung vacs for more reliable electronics from major supplier, and the iLife W400 Shinebot mopper with water extraction, rotating brush instead of just mopping pads. Samsung also more powerful suction useful for carpets. I spoke on this industry technology at The Villages science club. The newest models have self-empty, separate vac charging bases with large bins, expensive, and camera vision of floor avoiding obstacles and obstruction. Wide range of prices and features in this industry. Caution Neato Robotics, bought by German appliance co. some years ago, is closing with support next four years only.
Amazon had tried acquiring venerable iRobot (Roomba brand) but blocked by regulators.
Which bot to use depends on flooring and furniture obstructions. Carpets need more than hard floors.
Best to buy where can be returned if doesn't work out in your premises. Various tricks can be used to assist with furniture, see robotreviews.

We've had one for years.
We like ours.
It's not a super-duper do all, but it does a nice job.

But you will have to name it.
I assume most posters here have named their unit.

Look at the features involving how it avoids obstacles. Issues that cause problems are getting stuck under furniture; stuck on a wire; stuck on the sliding door tracks; stuck on a tile to carpet transition; beaching on top of a flip flop, dog toy, sock...

I think the basic vacuuming is the same across all robot machines, but high tech vacuum cleaners (dyson) with true HEPA filtering capture the tiny particles much better than those paper filter cups.

We have a roomba. We learned to be careful with phone charging and laptop power cords, the vacuum will grab them. The vacuum also likes dog toys.
But the vacuum does a great job.

Don't knock it until you’ve tried a robot vac. We have Roomba & it keeps dust & pet hair to a bearable level. It’s not a full replacement for dusting & vacuuming but it’s worthwhile.

CAUTION: yes, it does make a gross mess if your pet leaves a surprise on the floor. Cleaning the trails it makes & inside the unit is really awful. It also terrorizes pets since it keeps going until it hits their legs. My dog tries to bite the Roomba which would be pretty funny but I fear it could hurt her.
