Re: Internal flex suction hose is leaking
The hose where it hooks to the motor unit usually splits there, if this what you are talking about, then you can replace the hose asm. Part #
H-90001336 You can go to http://vacuumsuperstore.com/ and order it thru them, or call a local service shop.

If you turn the suction valve to tools and block the hose you should have no air coming out of the filter. If you do it may be a bad diverter valve. Another possibility is a leak in the system. You can also do the same thing with the hose inside the rug nozzle. If they were both sealed off that would confirm an internal leak.such as a motor gasket failure.
This issue you've described with your DC41 sounds unusual, as the changeover valve will divert suction to the cleaner head automatically when you recline the machine into the vacuuming position. If it's not doing this, it's possible you have a blockage somewhere in the cleaner head, internal hose or changeover valve.
Check the flex hose between the power head and body of the vacuum. If it's cracked, which is likely, there will be a substantial loss of suction at the brush area.
To remove, simply lay the prolux on it's side, pull out the end connected to the power head, then unscrew the end connected to the tank. Turn in a clockwise motion to do so.
To install new hose, screw into the tank in a counter-clockwise direction. When firmly in place, gently push other end into the power head. Manipulate it so it is all the way in.
The filter may be relatively clean, but if there's a lot of fined dust in your area the pores of the filter will fill and clog fairly quickly. Try replacing the filter and see what happens. If you don't have a spare, consider purchasing one for use while the other is drying out. Then alternate.
A leaky hose could also cause a loss of suction, as could a broke or cracked flex tube (the short piece in the power head).
I assume you've checked for blockages and that there's a useful length of bristles on the brush roll. Turn the machine over, and just behind the brush you will see a short length of clear plastic tubing with spiral reinforcing. That tube often splits, so there's an air leak and consequent loss of suction at the brush. A split may not be immediately obvious - to get the tube off, pull it off from the motor end and then unscrew it at the brush end. As a temporary measure you can cover a split with tape, but the tube undergoes so much flexing that tape is rarely effective for very long. A new hose (it's called the internal hose) is not expensive and is the only permanent solution.
If the internal hose is not split, post a reply here and we'll see what else we can think of. Good luck!
Most common cause of this problem is a damaged flex. Damage may not be visible externally, but after a lot of bending and pulling the wire inside the flex can break. This usually happens close to the plug, so examine it very carefully for signs of damage (if there has actually been a short circuit, there may be a tiny hole blown in the outer insulation). Unfortunately there is no easy way to locate an internal break without special testing equipment. You can try just cutting off the old plug with about 6 inches of flex, and then fitting a new plug - if that doesn't work you may need professional help. Good luck!
Most likely is a break in the electric flex. This can be internal, and completely invisible from the outside. Alternatively, the cable may be visibly damaged so check it carefully. Internal damage usually occurs at the extremities of the flex, where it leaves the plug or where it enters the machine, it's hard to detect without suitable testing equipment, although simply moving the flex around (with power switched on) will sometimes locate the problem. Depending on your wish or ability to deal with this yourself, there are several solutions. Of course, if the fault is at the plug end, the old plug can be cut off and a new one fitted. If the fault is at the machine end, the handle can be re-wired but the usual solution is to fit a new handle (complete with flex). This is more expensive in material terms but works out cheaper than a re-wire when labour costs are added (there's no labour in fitting a new handle, but re-wiring a handle takes time). If this doesn't help, please post a further comment, indicating how confident you feel about taking the machine apart, and we'll consider other options. Good luck!
Hi there SmartAlec from NelsonVacuums.com.au here. If your only going to use it once you can remove the washable filter it is likely choking the suction off and is in need of replacement. If this improves the suction you can purchase a replacement dyson filter here. Hope this helps. Happy Vacuuming :)
remove the filter from the dirt cup and try again,if you have suction the the filter is clogged.the other is the intake hose that goes into the top of the base where the clear tube is.disconnect the hose from the base tube and take a coat hanger and bend the end into a hook.open the litte flapper door and stick the hanger down in the tube and see if you can pull out a clog of dirt.last but not least,disconnect the top hose completelyfrom the vacuum and see if you can blow through it.if you can't then the flex top hose is clogged.open the little flapper door on the top of the base and turn on the vacuum,if the intake hose isn't clogged then you should have suction.that will tell you that the broblem is in the flex hose or the filter
most of those systems are plumbed with PVC, but some do use flex throughout the home...
If yours is PVC, visit your nutone dealer and get a new outlet/elbow.
Trim the old elbow off with a drywall saw or other small saw (if you have a sawsall, that is fine) and glue the new one in
if it is flex tubing, it's easier; the elbow threads on. just be sure to hold the tubing so it doesn't drop down,
