I have owned this vacuum for about 8 months now and it is the worst one. I love Shark products and have had other vacuums. It has horrible suction and do not recommended if you have pets. You have to pick up the vacuum and put it over the fur before it will try to pick it up.  It tends to just spin the fur in the head and then spits it out when you switch from hardwood to carpet. You also have to run it on the stronger suction setting which lasts about 15 minutes so its impossible to get a standard house done.
