Saw a few posts about the Qinux VultrioX and it seems to handle grass okay. I’m mostly curious if the wire brush actually works for moss on a concrete driveway or if it just scuffs it around. I don’t need it for heavy brush, just some green stuff growing in the cracks. Seems like it might save me from replacing trimmer line every five minutes. Any real world experience with that?

Wire heads do work on moss but they leave scratch marks on the concrete if you press too hard. I borrowed one from a neighbor and got the green off my patio, though it took a couple passes on the stubborn bits. Not sure I’d buy my own for that job alone.

For moss in driveway cracks it does the job better than line in my opinion. Line just whips over the top and the wire actually gets down in there and scuffs it out. It’s not going to make the concrete look brand new or anything, but it clears the green stuff.

Moss on concrete is a bit of a mixed bag with these wire heads. I’ve got a wire brush head on my trimmer and used it on the patio slabs out back where green stuff was creeping along the joints. It does tear the moss up, way better than line ever did, and I wasn’t stopping every ten minutes to bump the head. But it doesn’t really sweep it clean, it flings bits everywhere and some of the stuff just gets smeared into the surface. Took a couple of passes and then a stiff broom to actually clear it. On my concrete it left faint marks too, nothing horrible but you can see them in certain light. For cracks and edges though it’s handy. Just don’t expect it to look like you pressure washed it.

I’d say the wire part is what actually makes it worth trying for moss, because the green stuff in cracks just laughs at regular line. My dad has a similar steel brush head on his old trimmer and he uses it on the patio every spring. It does scrape the moss out of the gaps, but the big thing I noticed is that it works best when the moss is a bit dry. After rain it just smears around and makes a mess. He goes over the same spots a couple of times and then sweeps it after. No trimmer line to mess with, which is the main reason he keeps using it. It’s not a miracle tool, but for a driveway with light green growth it seems to do the job without too much fuss.

Mine chewed through the moss on my patio better than the line ever did. It does leave the concrete a bit rougher looking, but I got used to that. If you’re just doing cracks it’s a solid swap.

I gave up on line for that exact job and grabbed one of these instead. It does bite into the moss in the cracks, but it also chewed up the edges of my concrete a bit. Works, just go easy around the nice parts.

I tried a wire head on our patio moss and it was honestly more hassle than the line for me. It grabs the moss but also snags on every little edge, and I spent more time untangling than trimming. For light green stuff in cracks I’d just spot treat it instead of buying a whole head.

Wire on concrete just polishes the moss lol.

If I had that moss problem on a driveway I’d just grab the wire head and be done with it instead of fighting with line. I used mine on a brick walkway last month and it took the moss down to the surface without much fuss. It does leave the bricks looking a bit scuffed after, so keep that in mind if the concrete finish matters to you.

Mine handled the moss between my pavers fine, and I didn’t have to keep stopping to bump the line. It did take a couple passes to get down into the deeper gaps though. Way less annoying than replacing line constantly, that part alone was worth it for me.

Moss in cracks is about the only thing a wire head is actually good for. It rips it out without the line snapping every two minutes. Just don’t expect it to leave the concrete looking pretty.

I don’t buy the whole “wire head saves you from line replacement” pitch for this. I’ve watched a neighbor do his driveway moss with a wire brush head and it was slower than just hitting it with a line trimmer and a rake. The moss came up, sure, but it smeared green junk across the concrete and he still had to sweep and wash it after. That’s more work, not less. Line snapping is annoying, but at least it doesn’t leave a mess you have to clean up twice. For a few patches of green in cracks I’d just spot spray or scrape it by hand.

I’d just rent a pressure washer for that driveway.

I went back and forth on this exact thing before buying one, mostly because I couldn’t tell if people were exaggerating about the moss part. What actually made the difference for me was the surface itself. On my concrete it worked better than I expected, but I noticed it did way more on the thin green film stuff than on the thicker patches that had been sitting there a while. The thin stuff came off in a couple passes and looked pretty clean. The older clumps needed more time and I ended up going over them from a couple angles. So it’s not a magic one pass thing, but it did cut down the whole line snapping every few minutes annoyance for me. Curious whether your moss is fresh or has been building up for years, since I think that changes the answer a lot.

I haven’t tried that specific head, but wire brushes on concrete always seemed like they’d wear down fast to me. Curious if anyone’s had one last a full season on a driveway.

[Tom 2020]

Wire heads on concrete are a mixed bag. Friend of mine tried one and it ate through the wire fast on his driveway, way quicker than he expected. For a few patches of moss in cracks it might be fine, but I would not count on it lasting.

[Lisa Hall]

Mine just polished the surface and left most of the roots in the cracks, so it came back within a couple weeks. Wire heads seem better for knocking down dry dead stuff than anything actually rooted. I’d save the money and spot treat the moss first.

[Julia Writes]

Wire brush heads are the wrong tool for cracks. The wire just skims the surface and can’t get down in there, so the moss is back once it rains. A narrow scraper or even a flathead screwdriver does more in five minutes than spinning a brush around for an hour.

Pressure washer still sounds easier for a driveway honestly.
