Bold of you to assume my home is clean.

You’re never going to be sterile; good enough is good enough.

Keep an abundance of cleaning supplies. Soaps and rags in the kitchen and the bathroom. Think about investing in a vacuum and a carpet cleaning machine. Edit = Also get more trash bins. One for the kitchen, one for the desk, one by the coffee table, one for the bathroom.
Some people find it easier to do one big push where they clean the whole house in one session; other folks like to do a little bit every day. Figure out which type you are.

Also, check and see what cleaners charge in your area. It might be worth it to have a pro come in and do the work for you. Figure out what your leisure time is worth to you and then compare.

I can’t believe no one has said this… Don’t wear shoes inside the house.

This will dramatically reduce the griminess of your floors.

Its a big commitment. You’ll prioritise shoes you can just slide your feet into, or at least out of. I still have nice boots and stuff but wear them less often.

If you’re sweeping, it’s possible you’re kicking a lot of dust up in the air, so that by the time you’re done mopping, it has resettled back down on the floor. You could mitigate this by vacuuming instead, or opening your windows and using fans to blow air out of your house. But also, you’ll never get all of the dust anyway.

In newer construction, especially high-rise apartments, there’s a lot less dust. But in older buildings, it’s just an endless torrent, and the solution has been…

Robot vacuums

While they must be maintained, and won’t work well if you’re not diligent about picking up and keeping obstacles off the floor, they make it far easier to keep the whole house clean by reducing the overall volume of interior dust and debris inside the building envelope.

To illustrate (this will be gross) I change the bags about every month and weigh them and it’s usually ~1 kg (~2 lbs) per bag, and each year they remove roughly 30-40 kg (70-90 lbs). And every time I’ve cut them open to see what’s causing all the weight (or make sure nothing important was eaten) it appears to be mostly dust and hair.

It’s freaky thinking how all of that would be floating around, settling on surfaces, collecting in corners and crevices, saturating carpets and upholstery, and of course getting breathed in constantly. Instead I don’t have to manually dust and vacuum very often and our indoor AQI is usually better than outside.

So yeah. Robots.

Edit: added imperial mass equivalents

Keeping your house clean is a good thing to do. But it’s easy to stray into obsession territory. There lies madness.

Remember we all have far more visitor microbes in our bodies than our own host cells. Life is dirty. Life is germy. Embrace this.

You don’t need to live in a hoarder hell hole, but the sooner you accept that living is a messy business the more time you’ll have to enjoy actually living. Cleaning tasks should be quick and efficient, not sterilization.

Beyond that, there’s dusting, cleaning windows, sinks, countertops, bathrooms, and probably things I don’t even consider.

Of all the items you’ve listed, I personally rank floors as the most important to clean, followed by bathrooms, countertops, sinks, windows, and finally dusting. These are in order of which are used more frequently and how easily they’d be noticed. A dirty window (on the outside) is rarely dirty enough to outright block the sunlight, but grime on the floor will be tracked into other rooms, worsening the issue. Bathrooms are used daily, so would bother me if they’re not at least reasonably seemly.

For keep floor clean, the zeroth step is to prevent dirt and grime from coming in at the onset. A shoes-off policy in the home is probably the most substantial in this effort. That’s not to say you have to go barefoot – although I do think it’s quite nice – since indoor slippers or shoes are an option. The next step would be to rip out all wall-to-wall carpet, if possible. I have a full rant about the drawbacks of carpet, but it will suffice to say that carpet traps dust and dirt whereas hard surfaces like tile or laminate do not.

After that, you may need to identify what exactly is dirtying your floors. If it’s loose particulate (eg food crumbs), that’s going to need a different solution than if it’s loose hairs, which is different than dust or clothes threads. Crumbs or hair might suggest localized sweeping in the kitchen or bathroom will be most effective, while dust or threads suggest you need to adjust your clothes dryer settings, or your central air system needs a new/different filter.

The thing to keep in mind with all this is that grime does not come from nowhere: there is always a source, and the evidence will lead you to what’s most effective to keep your home maintained. Even if you conclude that the dust is fallout from the nearby coal-burning power station, there will still be things you can do, such as campaigning for a fossil-fuel free world electrostatic air filters or keeping doors closed when not needed.

I have a roomba to get rid of 80% every day. I strive to manually vacuum once a week, because the roomba doesn’t do corners and some hard to reach bits. Nor can it do stairs, obviously. After vacuuming I run a steam mop over the floors, which is amazing and SO much faster than regular mopping, without any cleaning agents.

Since its a combination steam mop/hand thing, I also use it for the windows. That’s not on any schedule, just when I think they’re dirty.

I wetwipe the countertop after I make dinner, and I clean it with soap whenever it looks dirty enough to be worth the effort.

Honestly, things like wooden floors can be hand-scrubbed four or five times before being actually clean, but it feel that anything that’s stuck on there after running the steam mop is probably not coming off during normal use, so it qualifies as clean enough.

I pay someone to clean once a month. I hate cleaning and it’s worth the $200 to me.

I keep my sink clear of dishes and take out my own trash, but the rest is just stuff I don’t want to do.

I have 2 dogs and a cat and have hard floors throughout. The roboVac runs twice per day and is always FULL when I empty it after every run. In addition my roboMop runs 3 days a week. My job at home is no longer cleaning but, roboTending 😂

But yes, taking off your shoes from outdoors is a must. We all keep a pair birks just for use inside.

Vacuum. It sucks up the dirt and traps it.

Brooms & mops were from the ancient days before electricity existed, and as you’ve experienced, the dirt just keeps circulating and never goes away. Endless filth & frustration.

Set a weekly cleaning day and stick to it. On weeks when you can’t clean on that day, move it to a different day. Don’t skip.

And no shoes inside, ever. Tracks in lots of filth, even when you think you have clean shoes.

I have a mastiff. Truly clean will never be a thing again.

i don’t.

I’m a little late to the party but keep in mind that people who stay on top of cleaning and have sparkling houses are doing just that and nothing else because it is so time consuming. You don’t want to invest all your free time (or all your time) into cleaning that will never end. Good enough is good enough.
