My 4th Von Haus vacuum cleaner, to use in a 4 storey town house and a small cottage. I have hard floors and sisal. They all work still, unlike my previous (v. expensivee) cordless vacuums. which stopped charging after 2years. I prefer the two long handle versions of the 4 that I have.

Pros: Suction very good on the hard floors. The long lead and largish dust bin, means I don't have to replug or empty the bin before getting around the whole floor. It's lightweight and the handle disconnects at the push of a button, so vacuuming my many steps is easy. Great value for money. 
Cons: it's noisy, gets very hot in use (comes with a warning that it may cut out) and the crevice tool is fiddly to use.
