I own two Hoover Carpet cleaners, one smaller and one that is larger. They work okay and I was happy with them.
Last fall, I went to a friend's home and she just cleaned her off white carpets. They were beautiful. They were never that great looking before. She had a Bissel Big Green carpet cleaner.
I was so impressed that I looked into them. They are expensive. I finally caved and bought one using points from a credit card which helped a lot.
When it came, I immediately cleaned my second floor hallway and master bedroom although the carpet wasn't dirty...or so I thought. Then I cleaned the carpet in my RV that I thought was spotless because my DH shampooed it already with the Hoover after our last trip. I couldn't believe the dirt that came up.
What a difference! I love that machine. I am thrilled with my purchase. That carpet cleaner is wonderful and makes even old carpets look like brand new. It was worth the money and more.
There is one downside. When full, the machine is very heavy. I would think the Bissel you posted is too. If you need to move to a different level in your home, you would need to remove the water tank and move it separately.
i noticed that Home Depot rents these machine out. People could try before they buy or just rent when needed and not have to worry about storing a large unit.
i saw the Hoover you are looking at on HSN this week in action. They probably have a ton of reviews on their site. The host, Adam said this was their best selling carpet cleaner.
