This vacuum cleaner must be in Superman's cape! I was very impressed with the job the SC899F did on my carpet. I have deep pile carpets in my house. Once a month my cleaner vacuums with a Sanitaire Commercial Vac and the carpets look and feel like new. I bought the SC899F for my own use because I always want a new and fresh carpet to clean. My Sanitaire came with a shaker bag, I know it won't fit me so I bought a regular cloth bag to use the F/G type bags with the machine. I wanted to test the Sanitaire's deep cleaning ability, so I used my 2008 Baggless Pet Vac (new air filter/belt) on the carpet in my house. I then placed the bag in the SC899F and vacuumed the same area. We learned the hard way to put the bag in the right direction because when I opened the Sanitaire cloth bag, there was dust everywhere. Still, I was very excited to see the dust because I knew this SC899F was picking up a lot of what my Pet Vac left behind. Needless to say, I duly put the bag back and started vacuuming the rest of my house. The suction power of this vacuum is insane, I can see the vacuum picking up the carpet and doing its job. It was easy for me to maneuver and clean along the baseboard, I didn't miss the wand. Being commercial I can understand that this vacuum cleaner doesn't have a light but who cares, you can vacuum in the dark with this thing and it can still do its job. .Great vacuum cleaner/great price/great carpet
