If the suction has decreased, clean/replace the filters and check for obstructions in the pipes. If you still have no luck call the 0800 customer service number. That's what my bro tells people when they say suction has decreased as the customer service people will walk you through getting to the reason, they have vacuums in front of them to walk you through the process apparently.If I'm hoovering I tend to grab the Dyson, although I think ours is due a bit of an overhaul, as it doesn't seem to pick up very well these days - I remember the day we got it from Comet and were amazed at the amount of dust and cat hair it dragged out of the carpet.

Yeah they are terrible if used with any sort of really fine dust, like the kind created by building work. The foam filter is really good at filtering out very fine dust with it being a hepa filter, but this means it clogs in seconds if sucking up a lot of fine dust.


but seriously it makes my Dyson look like a toy,you can see the carpet lifting up from the floor, it will pick up half the crap,that your Dyson wouldn't beable to, but then again,its the Rolls Royce of vacuums and costs it. Must also say they weigh an absolute ton.
