I have a 5 year old Lindhaus bagger. I tell you the lack of cleaning up is nice.
Ran into my first Bissel Powerforce today. It was on a move out, I was using my Ninga and never had my Lindhaus on board. Custy had a few items left at house including the Powerforce. Took me 20 minutes to clean the thing up. It had blockages in the hose, power head, and filters, whole machine was covered in dust.
Unit cleaned up like a gem and sucked like a banshee (I think banshees suck?).
