SCVACUUMGUY
I have to wonder........Those pics you posted........I'll bet the reason the inside looks like that is the fact that people using them don't change the water when vacuuming.......They let it turn to MUD.
If someone buys a Rainbow and uses it from day one and changed the water before it gets to the point of even getting close to becoming thick, I'll bet the inside doesn't look like that...But most people won't do this. They fill it once, vacuum the entire house and when they are done they have a basin full of mud and a rainbow full of dirt.
I remember growing up and my Grandma had a Rainbow in the 80s.....When we would vacuum her house, we didn't change the water often at all......I remember taking the basin outside and dumping it in a ditch...........Rainbow doesn't mention the fact that the water needs to be changed often.
I guess they don't want to harm potential sales by saying this.....To me now, it's just common sense......
I would also think that would smell, having that dirt inside the machine trapped like that, right?
Mine still has that clean Rainbow smell.
I hate the power head on the Rainbow though.........And will AGREE they are way overpriced.
But I think if used correctly, one will not have the issues
