I purchased my Electrolux vacuum because I wanted a mini vacuum to do the stairs. Although perfectly happy with my big old Dyson for general room cleaning, it's heavy & not good at stairs. (It's nearly fallen on me when doing stairs "from above" & if it's left at the bottom, it fights me as I'm trying to stretch up to do the top steps.)
I read a lot of reviews before choosing the Electolux & I'm really pleased I settled on it. It has the most amazing suction which gets the job done in half the time. It IS a little noisy, but being a hand held, that might just be because you have it closer to your ears!! It's also not the lightest hand held, but it doesn't matter if the job gets done before your wrists get tired. It's very easy to operate & seems compact & sturdy (although I haven't dropped it yet, so only time will tell). You should empty the dust out after each use but it's an easy job, although after tipping out the bulk, I recommend using a rubber glove to "stroke" away the fine dust, rather then bashing the chamber in the bin, as that just sends dust back into the air. The rubber glove takes the dust off a treat without undue mess.
Any little bits that the vacuum can't reach in the crevice of the steps, are easily picked up by the integral hose, which also has an amazing suck & an extra crevice tool hidden in the base.
My only reservation is the cord storage. It wraps around the end of the vacuum but it's a shame that there isn't anything to stop it unravelling.
