I've had this vacuum for about 8 months. The fro t wheels keep coming off and I have to pick up the pieces and use pliers to pop them back in. This started after the wheels weren't moving smoothly anymore on hardwood floors.  My other issue is that on low power it's practically useless and on the highest power the battery dies in a short time.  I have dogs and vacuum frequently. The pros are not having to manually dump the dust and first after each vacuum. It also looks really nice and tidy.
