I have cleaned it with a parts grabber (looks like a little spider in the end of a flexible shaft) and it sort of works...however, I would like to know how to take it out of the unit so I can really clean it out.
I guess I am looking for a way to do this without breaking the little tabs, etc...
Is there a book for this unit that would show the teardown/rebuild procedure?

If your suction is ok for normal cleaning and bad for just the hand tools then you have a blockage in the flexible hose or the "u pipe" at the bottom of the flexible hose. Un-clip the u pipe and check it for blockage. Un-clip the hose from the vacuum and you should be able to look through it when letting it hang straight down.
Hi, Barry. W/D here. I have just experienced this problem, and here's how to fix it.
Remove the canister from the cyclone separator. One sign of clogging is debris on the filter located under the canister. If debris is present on the filter, clean it with soap and water, then dry thoroughly while you proceed to the next step.
Looking up into the cyclones from the bottom, you will see the holes that correspond to each cyclone. I use a flexible grabber that is used to retrieve nuts and bolts. (It has a spring and thumb driven end that allows small jaws to open when the thumb end is pushed, and the jaws close when the pressure on the thumb drive is released). Pass the jaws end up into the hole(s), one at a time, opening the jaws as you clear the opening. Insert the grabber fully, and then release the jaws. Retract the grabber, and remove the debris captured by this method. Repeat as necessary. These grabbers are easily found at most hardware stores, and are inexpensive.
Compressed air may aid in removing debris, or at least move it around to where it may be more easily grabbed.
Lastly, you can disassemble the cyclone chambers to inspect and clean. The canister has three molded in lugs located internally behind the canister gasket. You will have to remove the gasket and carefully separate the halves. Use a sharpie and make match lines on your pieces as you separate them from here on in, to make reassembly easier. Once separated, you will have access to the screws that hold the cyclone assembly to it's base. You'll need a #20 torx bit to remove these. Once removed, remove any debris and clean all parts prior to reassembly.
This should have you thoroughly cleaned. One other thing....dump the canister frequently; if you wait until you are at the full mark, you have probably gone too far.
Have you tried cleaning the hose from the vacuum end, the end that feeds the sweepings into the cannister/bag? Might be something close to that end of the hose.
Also, one reason for a hose not to work is the possibility of a cut or broken hose or a loose connection.
The closer an opening like this might be to the vacuum end of the hose, the less suction the unit will have through the hose as it will pull air through the hole/break easier than through the full length of the hose.
If you are confident there are no blockages, look underneath, where the brush is, and you will see a short length of reinforced clear plastic hose. This often develops a split which results in loss of suction. You can pull the hose off at the motor end and then unscrew it from the brush end to examine it thoroughly. If you find a split, it's best not to try and tape it up (except as a very temporary measure) - a new one is not expensive.
The first step towards improving the suction is to clean the circular HEPA filter. The filter also houses a circular sponge which should be rinsed and dried before putting it back. Check the HEPA filter to see if it needs replacement -- will look muddy! Another quick check is to remove the HEPA filter, run the vacuum cleaner momentarily in upright position to check if suction is restored at the hose end.
After doing this if suction is still poor or non existent, you should detach the transparent canister - a bit tricky since the release rod for the flap has to be aligned when you want to reassemble the unit. Once the canister is removed, you should check and clean the center tube/shaft for any clogged dust (use a wire coat hanger if needed to pry out the dust). This tube gets clogged if the vacuum cleaner was used to pick up damp/wet spills etc.
Hi there smartalec from NelsonVacuums.com.au here. Basically there is a colour coded (yellow if your vacuum is the one pictured) big button on the front of the machine where the pole joins the rest of the body just above the yellow part that is on top of the clear bin. Push this in and lift the handle up. Keep sliding the handle up until it make a click sound then press the little button at the end of the flexible hose which will now be at the bottom of the rod. The rod will now come completely off. You can put the cleaning tools in the end of the flexible hose and be cleaning in no time.
Happy vacuuming! :)
Hi there, SmartAlec from NelsonVacuums.com.au . I have fixed hundreds of Dyson DC07 vacuum cleaners over the last few years and i would say there are 2 possible causes for the loss of suction. 1st is that the filter looks clean but is actually worn anyway. The way to tell is remove the washable filter from your vacuum cleaner. Take out the foam insert this seems to last longer that the other part. Hold up the plastic cage to the light and look at the white part (well it used to be white anyway) you should be able to see light through it. If you cant see through it you need to replace it. Here is a link to that filter for purchase . To verify this is the problem just run the vacuum without the filter in you should see an improvement - note do not actually **** up material the filter is there for a good reason. 2nd problem is that you have a blockage in your radix assembly. If you take off the whole dirt bin and feel the suction on the upright part where the chamber joins the vacuum (basically bypassing the radix) if there is good suction here you will either need to replace the cyclone top or dismantle and clean it. (it is very difficult to clean as it doesn't completely dissassemble) Hope this helps - If you want more help send me a message HAPPY VACUUMING ! :)
Is there suction at the end of the hose, if not then the blockage is in the hose, unhook the hose and dig out the debris, if hose isn't blocked, then clean out the filters, if they get clogged, then air can;t flow thru them and you won't have suction. If you have suction at the end of the hose, then it is clogged down in the nozzle asm. there is an inlet by the brush roll and it comes up to where the hose plugs into. Clean the clog out.
