Before anything, let me apologize for the quality of the photos on here, they were taken with my cell phone in low light with no flash, tried to edit them to make them a bit better for you, the viewer.
This phase should be the simple part of this project, though the entire project isn't very difficult. A friend had a carpet cleaner they didn't want and were planning on filling a bit more of a land fill with. With summer on the way and already planning on building a small hydroponic system for some small starts I asked if I could gut it before they got rid of it.
Old carpet cleaner
Philips head screw driver
Maybe a hammer
Plastic sheet or work area you're not afraid of nasty old water spilling on.
Step 1: Tear Down.
Most vacuums/carpet cleaners for home use are pretty simple to dismantle. The screws which hold them together are fairly simple to spot, and if you can't figure out what it keeping a couple pieces together just look for a black hole that may have been covered by the last part of the housing removed, most likely there is a screw down in it.
