I have the Roborock Qrevo Plus, and it has been amazing! I have light colored floors and a black Dane and black Cocker. The robot runs every night and every morning we have clean floors. I have a 8 month old baby who is crawling so am also on the floor a lot and I’m always amazed by how spotless they are! Mapping was quick and painless, and I hardly ever have to intervene or rescue it. I also have a iRobot i3 and it’s a night and day difference. App is easy to use, and we have had it for just about a year and have had no problems. Refill clean water and dump dirty mop water once a week. Obstacle avoidance seems to work pretty well too, no incidents yet!

I owned iRobot i3 - worked fine, but only real sensor - was front bumper, so he was “dumb”. Best thing about iRobot is that you can replace every part without 3rd party help. I had it for several years, not a single problem whatsoever.

In case of i3 there was no problem with hair on the rollers. I cleaned hair from tips of the roller from time to time, but that was like 30sec cleanup. More hairs were collected in the front wheel, but it was removable and easily cleaned.

I have an irobot i3 and it runs every day without issues. The replacement rollers and filters are available cheap on Amazon. It collects plenty of debris and cat hair, mix of carpets and hard floors.

A robovac to me is not a substitute for vacuuming thoroughly once at least every other week. It helps keep little things off the floor, and gives you inspiration to pick up if you need it. I have a roomba i3 that cleans very well on carpet and hard floors, but yes you do have to make sure there are not loose cords or other objects around, I consider that a good thing. If you're looking to uplift fibers a cordless vacuum isn't the solution at anything lower than the highest price points. Cheap cordless vacuums are sweepers at best.

I had an i3 and it wasnt great. I upgraded to the 705 and I friggin love this one.

Any models with dual rollers imo. Any with single rollers dont do well with picking it up and get stuck with dog hair, even if they advertise not doing so. I've had i3 and it did fine and now I have 705 and it does even better.

And that sux! They are too expensive ..ordered the flow hoping it gets better in the corners and vacuums better..and guess I'm spoiled old roombas that are like tanks and last a long rime..has 3 yr warranty and comes with some stuff..I would think of it came to Costco it would be about the same.. but surprised doesn't have soap dispensary.. but does have a bigger battery so hoping 🤞🤞.. weirdly I cried giving up the 3i but it kept getting stuck in places I don't have problems with the others..😪

We have the i3 without the tower. It works ok. It helps, it still doesn’t get everything but it makes the floors look ok for a minute.

I have one basic Roomba that moves around randomly and another that supposedly maps the space. The cheaper, random movement robot is vastly superior in all ways.

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
