Hard disagree, because vacuuming is something you often need to do daily. Spending 10 min/day becomes over an hour a week. That's a significant chunk. If you have smooth floors, running a Roomba kind of becomes a no-brainer.
On the other hand, I only need to dust once a week, and that takes all of 10 minutes. Cleaning the bathroom is similarly once a week (assuming you wipe/brush the sink and toilet bowl as necessary after use).
Reducing vacuuming time, to me, is the #1 thing you can do to save cleaning time, if you live in a Roomba-compatible space.
People that don't vacuum that frequently, I'd assume, are also the type of people that don't clean a litter box for a week instead of daily.
I would not personally vacuum daily but having completely automated, vacuuming and mopping, every day has produced wonderful floors. Less work than what we did before too.
There's no germs involved here. Dustin on the floor is dirty socks, and you can peel crumbs and other things under foot under foot. It all goes away if floors are cleaned daily.
We also have building ventilation that is sadly unfiltered, so we have more dust than normal coming in.
We don't vacuum everything daily but a robot would really help us, we just won't buy an internet connected one or something that's very pricey. Our existing vacuum is crazy efficient and quiet.
Some people install domotic, always choose escalators and elevators over stairs, do everything they need to not move their ass during the day only to pay for a gym pass and spend more time at the gym than they have provably saved avoiding "living".
But I also get the difficulty when you have a space with lots of larger debris around. The robot vacuum was excellent before kids. Now with little kids that will leave toys and other obstacles all over the place, it requires diligence to pick up after them (and work to teach them to clean up their toys and socks) to ensure the vacuum can be effective.
And I'll show myself out…
I gave it googly eyes in 2017 and named it Harold.
It's an interesting idea but it just didn't work for me and I wouldn't consider buying another.
I don't know that I'd buy another, especially because the new ones creep me out with all the cameras and such, but as long as I can keep this one running, it does a good enough job.
With furnishing optimized for dust generation (less materials where the dust-shitting microbes live, like material curtains) and daily Roomba runs (plus eventual air filter running in the background) there is very little to dust off of surfaces. If there's little dust on the floor, it doesn't get kicked up and doesn't land on things. Ergo - Roomba makes dusting easier.
Unless you design your house and buy your furnitures taking these roomba into account, they get stuck nearly every where or at the first sock left on the ground by someone in your household. They have a number of wearable most owner will not even want to replace and will start being inefficient rather quickly. Add to that some battery wear and I don't think there is a lot of +5y old devices in the wild.
I and most people I know went back to regular vacuum cleaners. The thing is, those robots really don't solve a real problem as vacuuming and mopping are the easiest and quickest job when it comes to cleaning the house. Dusting all the furnitures + objects on top of them and cleaning the bathroom and toilets correctly are both much more time consuming and annoying jobs.
