I have always had Electrolux products and loved them.This one is disappointing. First I used the power head with the detangling button. In other words when hair builds up on the brush it takes the hair off. Well, it didn’t work. I had to cut the  hair off the roll. The 800 was powerful, but not as powerful as I thought it would be. The hard floor power head worked well, but again, not as I expected. I ended up returning it. It’s a shame because, again, I love Electrolux products.
