Well...this was a great idea poorly executed when the iRobot corporation decided to involve China in the manufacturing. Everyone here in America is quite familiar with the "crap" that China floods our country with. Well this item is no different! I have bought this "overpriced" piece of plastic crap for my wife, for Chistmas in 2007. Every month I was calling and having this and that replaced. Finally...because of the tedious cleaning that was necessary to keep this running, I quit using it.
Over the 2009 Christmas holidays I decided to get it out and use it. It did not clean one room before I started hearing this "clunk" "clunk" sound and removing the dust bin, I could see that the brushes were not turning. Yet another cleaning head has failed! You know...after spending $400 for something...that money should insure the buyer that the item purchased is not a cheap piece of crap that will break down continually until the manufacturer decides not to help you fix it any longer!
A year warranty? Not good enough! If you believe in what you make..and you know the term of "intended" usage, then give a warranty that reflects that! This cleaning head should have metal hardware and gears and not the plastic crap made famous by the Chinese hoard. Americans are willing to pay extra for quality. But until more Americans "wake up" and stop buying Chinese crap...this trend will continue until the economic collapse of this country.
This is great for pet hair! I can't believe what a difference it's made in our house. I have two long-haired dogs and we used to just throw up our hands and let the lint and dust and hair take over. Now I run the Roomba a couple times a week in each room, and it's amazing how much cleaner the whole house looks. At first the dogs barked whenever they saw it running, but now they give it a sniff and then leave it alone. It's so nice to be able to just push a button, leave, and come back to a clean floor.
