I know what you mean, Keith. Some "co-owner" brands don't do themselves any favours - by not listing spare parts on the websites as well as user manual links does not do that brand any favours; Electrolux, Zanussi and AEG UK need a kick up the behind - their online website customer email facility doesn't work, there is very little floorcare info that is up to date and some of their sites have poor spelling. Recently when enquiring about the drive belts for the Zanussi Airspeed upright I bought for my aunt, I had to send an email to
[email protected] to get a decent response - and Zanussi's current 2013 range can be seen on Amazon UK. Zanussi UK site shows zilch.
As consumers we are made to sit up and beg for good products to come along and when they do, they're not backed with consumables to begin with, but yet again made to sit and beg for brands to bring parts to the fore. But consumers and buyers/owners are learning this slowly over time and a few are now beginning to realise that by buying cheap supermarket exclusives and brands "you've never heard of," means buying spares etc is much harder, anyway.
No wonder buyers are confused and fed up - when large brands like Hoover and Electrolux fail to make spares available, the cheap alternatives are supermarket brands that force you to keep visiting that store or buying online etc to keep the vacuum cleaner going.
It is the market forces however that Tesco will go to sell whatever brand is selling the best of as well as what is available at the time. Tesco also sold those Wertheim cylinder vacs with power nozzle floor heads and top-of-the-line Miele vac which now has been whittled down to the S2, S5, S6 and S7 range despite advertising an S8 "with monster suction," but no models have yet been added to the site..
Tesco also sold SEBO vacuums but they have none listed at the moment. I'd say that its the market forces on what the average customer can presently afford as well as what appears to be popular at Tesco - no surprise to see Dyson's range on sale with practically every variant available.
