I am very disappointed in this item. The lack of suction, is mind blowing. It feels cheap, the attachments are cheap. The power switch is located where the handle is, so the device will keep turning off and on during operation.  I would highly recommend not buying this item.  Oh yes, and one last frustration, the   instructions are in  'engrish'! 
 Unbelievable! It's going back asap.
