Yes, and I've got two hoses* for mine, so it can suck and blow at the same time!
Actually, that used to be really useful when I cleaned out my parents old Ideal Standard boiler. Soot is really nasty stuff to suck up, because it's sticky, and the particle size is way too small to be trapped (often only a few hundred atoms). I found the best way was to use a bag full of carpet dust (the carpet fibres trap much of the soot by sticking). The bag paper will only trap the large clumps, with much of the soot passing straight through as it's orders of magnitude smaller than the paper bag pores. (Soot particles are small enough to go into the surface of many solid materials, which is why it stains so readily.) This is where a 2nd 'blow' tube comes in handy. You connect it up to the bottom, and dangle the end out of a window. Then you haven't got the really fine soot particles being blown into the air in the house. If you use the vacuum for long enough, the fine sticky soot will eventially clog the bag pores, and this can cause the bag to burst. The only time this happened, I had the blow hose out of the window, and the thud sound as the bag burst was accompanied by a thick black cloud billowing from the hose end. That would have been a disaster indoors. Glad to say we haven't had any appliances which collect soot like that for a decade now.
- The hose split at the end and someone bought a new one, and then I repaired the old one.
