Fixing Melanie's H2O Steam Mop

Project:
So I've always wanted to take apart my wife's H20 steam mop to see how it all works. NOT. But, I've been informed that it is on its way out and I just could not have that. Paying $100 bucks for something useful is one thing, but paying another $100 bucks for the same thing a year or two later just didn't sit right with me. So out to my shop I went to see what was going on with that mop. I took the whole thing apart and was amazed by its simplicity.

Reason for Project:
Melanie told me that there was hardly any steam coming out and that it would leave streaks on the floor. I had noticed over the last few months that the pump seemed to jug pretty hard and I wasn't sure whether the pump was actually getting worn out or if the pipes were somehow clogged.

How it works:
Water flows from the main reservoir (1) into the filter (2) through a semi-permeable plastic "port" (3). The water then flows through foam filters (4), through a mini water softener (5), then through some more foam filters (4). After that, the water flows through the pump (6), then then through the heating element (7) into the base of the mop (8). The pump is activated by a trigger on the handle (9) that pushes a switch (10) and that's how it works.

Here's a general overview of the mop with the reservoir (1), the filter (2) and the base (8)

This is the water filter between the reservoir and the pump with the semi-permeable inlet (3), the foam filter (4) and the compartment for the mini-water softener (5)

Here's a close-up of the filter element with the foam filter (4) and the mini-water softener (5)

Diagnosis:
The reason the mop stopped working was that the minerals of the water had clogged up the semi-permeable "port" (3) and would not let any water flow into the filter.

Fix:
Since the filter element was plastic-welded together I had to cut it in half with a small coping saw and clean out the foam filters as well as the little water softener beads (more on water softeners in the "additional resources" section), put them all back together and use 24hr epoxy glue to glue the two compartments back together. I took a zip-lock bag, mixed the epoxy glue together inside of the bag and cut the corner off so I had an accurate way of squeezing the glue out onto the area to be glued.

Tools:
Coping saw



Materials:
Epoxy glue, zip loc bag

Although it takes 24hrs to cure, it is much stronger because of its flexibility to hold the two parts of the filter element together.

Update:
I just couldn't wait the full 24 hours to test the mop so I plugged it in tonight and it just didn't seem to work right. I was kinda disappointed but stubborn as I am (and Melanie would gladly attest to that), I tried to figure out why it didn't work. Well, I discovered that the filter compartment I epoxied up had a small hole in it so the pump couldn't create the vacuum needed to suck the water through the heater and out at the bottom. After another bead of epoxy (I used the 5 minute stuff this time) I plugged her in and she worked like a charm.
