I Spent $420 on Smart Cleaners — Here's the Unvarnished Truth

Last November, I made an impulse buy: a robot vacuum and a floor scrubber, total around ¥3000.

Six months in, here’s my honest review. Regret? Some. But not entirely wrong purchase either.

Let’s talk robot vacuums first

Before buying, I pictured this: come home from work, floors spotless, nothing to do. Reality check:

First, robot vacuums do save you a ton of effort, especially with hair and dust on hard floors. BUT — they can’t reach corners, can’t fit under most furniture, and are useless against anything bigger than a crumb.

Second, they need regular maintenance. Brushes to clean, dust bins to empty, filters to replace. Hidden labor nobody tells you about.

Third, when it gets stuck somewhere — and it will — you’re hunting all over the house. Mine wedged under my bed once. Took me 30 minutes to find it.

Verdict: Robot vacuums are great for daily maintenance, not deep cleaning. If you’re naturally lazy and keep a tidy home, they’ll save you serious effort. If you expect them to replace manual cleaning entirely, you’ll be disappointed.

Now the floor scrubber

This one I regret more. Marketed as “sweeps, mops, and sucks up liquid in one.” Here’s what actually happens:

It’s heavy. Like, really heavy. My wrists got tired, especially doing larger areas. The clean water and dirty water tanks are smaller than advertised — you’re refilling and emptying constantly.

And the brush cleaning part… I’ll spare you the details. But it’s gross.

That said, the scrubber does handle liquid spills better than robot vacuums. Kitchen and bathroom? It’s useful there.

My advice

Before buying any smart cleaning device, ask yourself three questions:

One — what’s your floor made of? Wood and tile work fine with robot vacuums. Carpets? Effectiveness drops significantly.

Two — how cluttered is your space? Lots of furniture? Robot vacuums will struggle.

Three — how often will you actually use it? If you can’t commit to running it daily, even the best device becomes an expensive dust collector.

On budget: ¥1000-2000 mid-range models are often better value than flagship devices. Those premium features? You probably won’t use them.

Final take: Smart cleaning devices are “nice to have,” not “set it and forget it.” Don’t expect them to replace elbow grease — regular maintenance and realistic expectations are key.
