This cordless vacuum cleaners is head and shoulders above the competition. Just the basic concept of switching on rather than having to continually hold down the control is a game changer. Add the incredible light which sees the tiniest bits of sand or dust which escape the eye. A quiet operation with larger head covers way more ground with less effort. Granted it is a bit heavy at 4kg but not an issue when you consider its brilliant performance. Love the extra battery which allows proper cleaning of our large two storey, 4 bedroom, study, separate formal and informal living areas plus large games room, home. Only negative as others have noted is having to empty the dust container a couple of times each long use. Not a huge problem and is easy enough to do. Love this German made quality vacuum cleaner - makes an otherwise tedious task almost a pleasure! Well worth the money.
