I had a chance to have a good go with the DC41 Animal as my friend wanted me to restore it. This is what I thought of it;
The vacuum has an awful wand mechanism. There is no handle that gets in the way. Yes that is good, but it is not really comfortable to hold whilst in use.
The DC41 Animal has more flexible plastic, but there seems to be a design flaw where the left side of their so called "ball" has a pin joint which snaps off. This needs to be sorted out.
To clear out a blockage, the only things you can do are remove the cleaner head, take off the hose & wand and also the cyclone just to check the uptake pipe and flip the small clear window up. The hose is inside the casing so I wouldn't recommend vacuuming up things like pine needles or else it would be a pain in the rear just to unclog the vacuum.
The bristles have pretty much the same stiffness as a non clutched Dyson brushroll.
The suction is not very impressive as it has less than a DC04 which is a much better vacuum and retailed nearly a half as the DC41!
The DC25 is a much better vacuum in terms or sturdiness, performance, and noise levels.
Anecdote- I would go for the DC25 over the DC41 as I want a reliable machine which cleans good, one I can rely on and also is a much more better designed machine. If I have a blockage for example, atleast I don't have to use a screw driver and do half of a machine tear down just to access the internal hose! What if it rips?
