Alex - respectfully I have been buying off auction sites and second hand sites well before you were born. Ebay came to the UK in 1999, which would have put you as being 5 years old.
"Second hand does not really constitute for being used a few times."
Oh yes, it does. You forget there is something called "in context" where auction sites are concerned.
Not all second hand vacuums or appliances have been chucked around a home and abused. Maybe the ones you've bought have. The majority of mine haven't but then I've often checked the listing throughly online as well as communicated heavily with the seller before considering.
Let me give you a classic example. From collecting vacuums and buying from previous online sites like PRELOVED.COM before Gumtree ever existed, I used to collect a few Moulinex vacuums when I started out.. hardly any bags existed for most of the models unless I shopped purely at Argos or online.
When spare machines came onto EBay, they were hardly abused, and not all that dirty to the point it had me retching.
Very little to do other than to clean off the external bodies, maybe repair a broken pedal on a Wessel Werk style floor tool and at worst, declogging a vacuum whose bag had burst and rescuing and bringing back the motor to a newer, cleaner state.
Emma, yes there is a difference to being fully restored and second hand. It is never easy buying anything off an auction site, let alone "sold as seen" style with Argos.
But there is also something called "refurbished," too. That term in my opinion has become badly abused and used.
On EBAY UK in the last couple of years a lot of sellers are jumping on the "refurbished" title where fitting a new filter does NOT constitute as being completely "refurbished."
The proper term of it means "making new" and where if the body of a vacuum or its external part may not affect performance, it will not be changed. Everything else is usually changed to maintain the original model's performance.
Bagintheback - sadly second hand vacuums means you get any condition. I've often seen great listings for SEBO and Miele vacs but then wondered why the listing information is suspect. You take your chances, but at least EBAY&PPal have buyer support; even if that POLICY alone can also be abused.
