Query: Don't waiste your money. It's badly designed

Like most user complains after a period of use, it's start kicking dirt around instead vacuuming. The unit develop a poor suction even with all the filter cleaned after each use.On the hard floor, the air pressure created by the brush unit is much stronger than the vacuum unit. The excess air will blow the lint and dirt away from the vacuum machine instead of collecting it.You might be better of using a broom.
