I wanted to love this vacuum cleaner. It's lightweight, has a hose attachment, and is very powerful. But after the third use I started noticing the dirty smell of the vacuum cleaner. Mind you, my house is very clean, I have a new 2x8 mat that is 3 days old and I've only used it to vacuum the hair of a non-shedding cat in 2 rooms. After vacuuming, I smelled this dirty smell, and then I noticed that the air was coming from the side of the vacuum where the side filter is. You can feel the heat and see the dust on the furniture, which I only noticed the third time I vacuumed. Very disappointed. I would not buy this vacuum cleaner. My family and I sneezed for three days before realizing what it was.
