The Future Of In-water Hull Cleaning

The Remora brushes are mounted on an impeller hub so when the brush rotates, the machine sucks itself to the hull. All the diver has to do is drive it around. That said, it does produce some torque (especially when used at higher rotation speeds) that requires getting used to. You develop a new set of muscles that you don't use so much when cleaning by hand.

Well, extremely foul bottoms (hard, 3-dimensional growth) that required scraping before cleaning by hand with a pad will still need to be scraped before going over them with the Remora.



No. I continue to be surprised at how gentle the machine is. Like any cleaning media a diver might use, the potential to damage the paint exists with the Remora. But by selecting the proper brush and rotation speed for the fouling condition and paint type, I believe the Remora actually removes less paint than cleaning by hand. It absolutely provides a more consistent cleaning as opposed to doing it manually.







I work in saltwater marinas. Electric Shock Drowning (ESD) rarely (or never) occurs in saltwater, as has been discussed here ad nauseum.
So- the Remora is only for sale to people using it in salt water?

Because it's electrically operated. ;)
Well yes, it operates on a 12 volt battery. But since it's a watertight unit, the diver is not in contact with any electrical components. Completely safe to use in freshwater.

I think they mean just dealing with the stray electrical currents that could be within a fresh water marina itself and not just the 12 volt tool.

$3,105! Ouch.
That was two years ago and frankly, I think the price is wrong. Hulltimo at that time was selling their simple pole-mounted, battery-operated rotary brush for about that price. I can't image their robotic hull cleaner going for less than $10K.

That said, the company seems to have changed hands and countries. Not sure they even sell the Hulltimo Pro anymore.

:laugh: That's insane.
They were marketing it as a business opportunity. Instead of having a diver come out, you'd hire a guy trained by Hulltimo (but running his own hull cleaning business with the Hulltimo Pro) to come and drop his robot into the water and then drive it all over your hull. I think we can guess how well that worked out.

I actually own a Hulltimo pole-mounted rotary brush. If anybody wants to buy it, I'll make you a screaming deal. :thumbup:

OK, "own" may be a bit of a stretch. Hulltimo sent me the machine some years ago to use and provide feedback as a diver-operated unit. While I could tell that a battery-powered rotary brush was the future of in-water hull cleaning, the Hulltimo had some serious drawbacks. After using it for a month or two and taking a meeting with the designer/inventor, I tried to return it. No replies to my e-mails or phone calls. Ive had it ever since. I guess it's mine!

Awesome tool, but the "toilet plunger" intrigued me as much.
I think you're wrong, Bob. That's one of those things from RIO to give the athletes hickies . Dang, that's the first time I've seen spellchecker on this forum. Hickies.
