I'd suggest the Bissell SpotBot, it's a bit less hands-on and works quite nicely.
Yes, I would recommend it very much. I have one and use it all the time, never had a problem with is and it works very well!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
