Query: Not good enough

We had the old swiffer and it worked pretty good, it would pick up virtually anything from the floor.This new on is not at all like that. It's not strong enough.If you have dust or vey light dirt on the floor, you have to pass through very slowly so it can pick it up, and sometimes it doesn't even do that consistently.Another step backwards is the on/off switch. It used to be in the handle, so with only one hand you could do the whole thing.Now is is down where the engine is, so you need to hold it with one hand and turn it on with the other. It's a minor thing, but when you can compare with the old one which was really good, then you see the difference.The concept is very good, wireless and very light, but I think they went back a step with this new model.
