Okay, let's talk about this. I got one of those battery-powered portable power washers a while back. Super handy for quick jobs, right? Washing the car, cleaning the grill, that sort of thing. Didn't need to drag out the big gas one every time.

But then I looked at my patio. Ugh. Took forever with the little nozzle, just making stripes back and forth, back and forth. My arm got tired, and the battery would die before I was even halfway done. I have one of those big round surface cleaner attachments for my gas washer, the thing that looks like a floor buffer, and it cleans the driveway super fast. So, I started wondering...

My Search Began

I figured, maybe they make a smaller version for these battery things? Seemed logical. So, first thing, I went online. Typed in stuff like "surface cleaner for battery power washer," "small surface cleaner attachment," "low power pressure washer surface cleaner."

Found a whole bunch of surface cleaners, yeah. But they all talked about needing a certain GPM (gallons per minute) and PSI (pounds per square inch). My little battery washer? It's got spirit, but it ain't got that kind of power. Most specs listed were way higher than what my portable unit could push out.

I got a bit discouraged. Thought maybe it was just a dumb idea. Battery washers are great for light stuff, not for heavy-duty attachments like a surface cleaner, right? That’s what I figured.

Did I Find Anything?

Well, kinda. After digging around more, I saw a few smaller, like 6-inch or 8-inch diameter, surface cleaner heads. They looked like the big ones, just shrunk down. Some ads were kinda vague, didn't list super specific power requirements, or maybe mentioned compatibility with electric washers, which can still be more powerful than the battery ones.

I found one that looked promising. It was small, light plastic construction. The description wasn't super clear, but it didn't have crazy high PSI requirements listed like the big metal ones. It wasn't expensive, so I thought, what the heck? Let's give it a shot. Ordered it.

Trying It Out

When it arrived, I hooked it up to my battery washer wand. It used the standard quick-connect fitting, so that part was easy. Felt a bit flimsy, but okay.

I charged up a fresh battery, filled the washer's bucket (mine draws from a bucket), and took it out to the patio. Put the cleaner flat on the concrete, took a breath, and pulled the trigger.

• The Spin: It did spin! The little arms underneath started rotating, just like the big one. Not super fast, but it was moving.
• The Cleaning: Well... it sort of cleaned. It was definitely better than just the narrow jet nozzle for covering area. It made a circle pattern, about 6 inches wide. But the cleaning power? It was weak. It took off the light layer of green algae, but any ground-in dirt or tougher spots? Nah. I had to go super slow, like snail's pace, to get even mediocre results.
• The Battery: Oh man, did it drain the battery! Because the washer was constantly running to keep the spinner going (even slowly), the battery died way faster than usual. Faster even than just using the regular nozzle continuously, it felt like.

So, Is There One? My Final Thoughts

Technically, yes. I did find and buy a surface cleaner attachment that physically connected to my battery power washer and did spin when I turned it on.

But does it work well? Honestly? Not really. Not for me, anyway. The power limitation of the battery washer is the main problem. It just doesn't have enough juice (GPM and PSI) to spin the cleaner effectively and blast dirt away like a corded electric or gas model can. It was slow, weak, and killed the battery super fast.

So, my experience? It was kinda disappointing. The idea is good, but the reality with current battery washer tech (at least the affordable ones I have) just isn't quite there for this kind of attachment. It ended up being faster, though more tedious, just using the regular fan nozzle carefully. That little surface cleaner attachment is now sitting in a box in my garage. Maybe someday battery washers will get powerful enough, but for now, I'd say don't waste your money if you were hoping for results like a real pressure washer.
