I have never had good luck with Gorilla glue on a non-porous surface. (On wood and fiber it is AMAZING though)
For plastics I'd look at solvent or thermal welding if the material is suitable. Any adhesive that is brittle, think cyanoacrylate (super glue) or most epoxy's are likely to fail on a rigid substrate. If you could arrange a lapped join, perhaps with a backer or sleeve over the join, Silicone RTV can be pretty amazing. Having a little flexibility in the bond coupled with a tenacious hold to the non-porous surface really works well. |

JB Weld has worked miracles for me. I prefer the type that takes 12 hours to cure.
I'm not clear on the hose piece that's broken. If nothing needs to slide over or into it, then you're golden and won't need to file down the glue after it sets. OTOH, if you do, it might be a tedious process if you have to do it on the inside of the glued piece. |

At $25 + free shipping + 10% off at Bissell.com I don't really think it's worth trying to fix the broken hose. Remember that is a tension zone and it's very difficult for any "glue" to stand for too long. If you already have the adhesives, it may be worth trying and maybe stretch the hose's life, but if you're going to spend money buying adhesives, it's better to buy the replacement hose.

I work for a plastics company.
Quite often the best way to repair something is to use the correct solvent to melt the edges and then quickly join them. Then let the part rest, preferably 24 hours, for the bond to cure. What solvent? That would depend on the plastic. I suggest taking the broken pieces to a place like Tap Plastics and asking them to determine what kind of plastic it is, and what solvent to use. |

So maybe it's time to replace the whole thing... I have the revolution pet pro and ...WOW... it's really better and much more powerful than ANY commercial stuff. Last use was saturday night, when a rider did what's expected from drunk rideshare riders in a saturday night. Huge mess REALLY cleaned up in less than 3 minutes + cleaning fee coming straight to my bank account. SWEET! |

can be a great help in repairing many broken plastic items, especially it the two pieces that need to be stuck together are difficult to hold together while any other type of glue “sets” and makes a bond. Hot glue sets almost immediately. I finally bought one at Christmas time this year and it came in very handy repairing some of our Christmas ornaments.

If you're trying to bond plastic parts made from ABS, look for tetra hydro furan, or THF. It's also used on PVC. TAP plastics should carry it. It's kind of nasty so you want a lot of ventilation when you're using it. It's highly flammable, and you do not want to let quantities of it evaporate by themselves to dryness, as that can form explosive peroxides. So keep containers tightly sealed and only use small amounts at a time. The good news is that it's not thought to be carcinogenic, but it readily penetrates skin and can cause dehydration of tissues. It also dissolves latex so use nitrile or neoprene gloves.
