This is the worse vacuum I have ever owned.   I have sent it in to be repaired, and only used it 4 times.   I received it back and used it for 3 seconds and it stopped.   Looked in checked the inside and found that LG had not worked on my vacuum because the obstructions inside the vacuum had not been removed.   I cleaned the vacuum of obstruction turned on and vacuumed for approximately 30 seconds it sounded alarm for obstruction, looked inside nothing.   This product is frustrating, can not handle pet hair, does not operate more than 30 seconds, and your service department is dependable to fix the problem
