We bought our dyson dco7 second hand off ebay about a year ago now and so far have had no problems with it. We payed just £30 for ours which I think is an absolute bargain for one of these Hoovers as they are great.
They have incredible suction power (far better than any other brand of Hoover i've had) and have a HEPA filter which is perfect for people with allergies. Strange as it sounds this vaccum always seems to leave my rooms smelling fresh everytime I use it, I can only guess this is something to do with the filter also.
This Hoover is great at picking up pet hair and is suitable to use on all floor surfaces which is one of the main reason we bought ours, it saves switching from hoovering one room to sweeping the next. It also comes with a really long lead which saves you switching plug sockets every 5 minutes. Another thing I find really handy is the length of the hoover pole, it means you can hoover the whole stairs in one go instead of stopping halfway and having to carry the hoover up with you to do the next.
Kept hearing about how great Dysons were so with 2 failed hoovers and cat hair and now dog hair and muddy paw prints to contend with I thought I'd invest in one! And again I've sung its praises to everyone! I don't think I will ever now get another make! The suction is incredible and I am easily pleased as I find it fascinating to see all the rubbish it sucks up so I like the clear holding canister! My previous hoover had a specific pet hair turbo tool which was rubbish and minute so took forever to cover a whole floor. This one does not need extra tools, the main roller and the power of the suction is enough to get up cat hair in one push. The canistor is easy to remove and emty. The telescopic hose and attachments are handy and again very easy to use. The lead is long enough not to have to keep unplugging and moving to another socket every room. I have been a little worried at the power a couple of times as I can see my carpet being pulled up and you do have to be very careful about moving things and curtains out of the way as it will try to take up anything in its path. Absolutely superb though at removing pet hair and dried mud! And keeping these cream carpets looking good inbetween washing!
