Query: This is a waste of money

I bought the littermaid in the belief that it would save time and effort dealing with the less pleasant aspects of having a cat. Nothing could be further from the truth.1) The machine itself is incredibly noisy.2) Cat waste often gets stuck to the rake.3) The lid of the waste recepticle falls from its holder and then the waste is occasionally dumped on top of the lid causing a huge mess.4) The rake does not pick up ALL of the waste no matter what grade of litter you use.5) The machine itself is tempramental and quite often will run backwards and forwards (great if you're trying to sleep) if it scoops the litter into a corner and can't get past it.Save yourself money and just get a decent normal litter tray. It's less hassle, less cleaning and less messy.
