I have tried a lot of other vacuums and I always had the same problem with them. My pets shed a lot so there's a lot of hair and all of these other vacuums just get clogged up all of the time. But not the Shark Stratos. It sucks it all up without getting clogged up in the tubes. Installation of the vacuum was easy. I didn't feel like I was trying to defuse a nuclear weapon just to simply put the vacuum together. The lift away is amazing for getting under furniture and appliances. The only things I wish I could change about this product wish I could extend the wand to reach higher places and I wish the attachments for those hose would attach to the hose. Most of the time I'm not sure if I have the attachments in there right and hope it doesn't just fall out while cleaning
