I bought a Shark mains vacuum some time ago, liked it, bought another.... now between home and work we have 2 mains powered and 2 cordless.
One of the cordless wasn't sucking and on inspection the hose in the base where the articulation goes on had split. So I pulled it apart, although not before buying tamperproof star keys (I had star keys but it seems manufacturers have gone to an added length to piss people off). Having got the part off and satisfied I could get it back together I went on their website looking for spares. It's obvious where this is going, they don't sell a hose but you can buy a whole new base. I emailed them and after a week of back and forth they confirmed that they do not supply parts, just whole new bases. Looking at the reviews on their site you can see many disgruntled people put out by having to buy a whole new base for the sake of a roller/pipe/belt etc.
I'm sure i'll find a suitable piece of hose and fettle it but this isn't really on, is it?
As for the ebay rant, One of the four vacs had a burnt out motor so I bought a whole new one 'reconditioned' on ebay, i'd never used the base and it was still in bubble wrap. I fished it out yesterday with the plan of robbing the bit of hose from it and lo, it was in worse nick than the one I wanted to replace but had a crock load of silicone sealant pasted onto it. Which I managed to easily remove with my fingers.
Therefore the hose appears to be a weak point in the design, but they don't facilitate changing it. So Shark are off my Christmas card list and I must thoroughly check ebay reconditioned stuff in future, I have learned many times now that stuff on ebay is on there because it is s**te.
