Thank you all for your replies.

I looked at the Oreck, but too pricey for me.

Does the Roomba REALLY work?

We have tile/wood in common areas and carpet in the bedrooms.

Works like crazy to pick up dirt/particles, but you still have to steam clean or mop tile and wood to clean.:)

The weight of vacuum cleaners is a major problem for me. I have an upright Eureka with attachments for serious vacuuming, but when I don't feel like hoisting it around, I have a Eureka bagless stick-type that I run around. It has a setting on it that enables you to run it over furniture too. It's much lighter weight and easier to handle though I do have to clean out the dustcup.

The Roomba ROCKS! it does a great job

The SCUBA also ROCKS as it washes the kitchen floor, bathroom floors, or other SEALED hardwood floors. no more sweeping, vacuuming or mopping! Whoo!

Now that I have all wood/tiled floors, I gave my roomba to my DD and am thinking of getting a MINT cleaner. Does anyone have one of these? It's cheaper (about 179.00 @ amazon) and you can use the swiffer cloths.
