Parwaz,
Not in my experience. The DC04 I purchased in 2002, required a 2 or 3 new hoses, 1 new handle, a whole new duct assy (main body) because it cracked and wouldn't keep the handle in (same thing happened to my DC24 - I must be heavy handed LOL). I changed the duct assembly myself on the DC04 but not the DC24. A new upholstery tool, but the one that replaced the older one was made of Polyproplene instead of ABS so the softer nature allowed it to withstand more.
The latest Dysons, even though I do not like the look and feel of the plastic used, may well be more durable as they appear softer, such as the handle at the top of the DC40, DC41 for example. Not trying to defend Dyson here, but I've not seen broken DC40's DC41s or DC50 in the shop, but used to see broken DC01's, 03's and 04's in the shops years ago.
My favourite Dyson was the DC03 and DC04 models. I very much like my DC24, but it hasn't proven to be very durable for me.
