When I used to refill, I discovered a mcdonalds straw matched the diameter nicely. i got a small funnel that also fit that straw. Pry the plug from the cartridge, put the straw in, suck the air out of the bag in the box, pour in your chosen solution, replace the plug.
Hi everyone!
So I'm using the CatGenius (B05 right now). And everything seems fine. I'm thinking about trying another solution (right now I'm not using anything and the cartridge is empty for a long time). So what is the right way to refill the cartridge??? Can I just cut a hole through plastic and make a hole in a bag and fill it with some cleaning solution???? Or it must be air sealed?? Thanks!
