I like it. It all depends how good the filters work though. The constant pumping seem like it could be a PIA. But using a wash mitt is a bit nicer opposed to a bunch of MF towels.
There is another 15 minute video on Vimeo where the dude demos it. But, for some reason he mixes regular wash solution with rinseless - so it's hard to tell how clean the solution stays (solution cloudy from "soap").
A while ago I came up with an idea of a "filtered bucket". It would be a rechargeable battery operated bucket with some type of electric fuel pump device forcing water through a filter type apparatus - chosen appropriately to remove damaging particles.
The filter / pump / battery part would be sealed off & built into the bottom of the bucket (walled off) so the bucket is balanced. It would be a 5 gallon size bucket, but the bottom gallon and a half area or so would be the mechanicals. It would be primarily for rinseless solution, the way I figure it you would need 2 gallons of solution max.
There would be a grit guard type device attached to it to scrub your mitt. There would be a few intake jets below the grit guard to designed suck in dirty solution in a swirling water down the drain type motion.
The clean solution would be pumped up a tube on the side of the bucket 3/4 of the way up. Kinda like an underwater fountain with an inline filter, or a pool filter.
I'm thinking this would enable you to do single bucket GDWM type washes with one towel and under 2 gallons of water.
The filter would obviously have to be some type of paper media type (easily replaceable), maybe with a screen type pre-filter (rinsable). The recharging cord would obviously plug into some jack in the bucket and would have a GFI.
I would want battery life to be around 2 hours (2 washes)... I'm not that familiar with battery technology - but my gut tells its reasonably possible without a super heavy battery - considering you will only need 2 gallons of water & depending on GPM. If the battery weighed 8-10 lbs I'd be happy.
Of course; all parts, filters, tubes, and battery would be replaceable (even the bucket assembly itself) and sold by me.
Ok. So now you can all make fun of me.
I have it figured out in my head. Maybe I'll invent it??
I'm thinking price would be between $200-$300... Which sounds like a lot, but if it kept the solution clean it would solve a lot of rinseless wash headaches and pretty much eliminate the need for a 2BM or washing a bunch of towels.
