This Vacuum Cleaner Floats…

This may be out of copyright now, but it's no new idea. The Spoutnik-like Hoover Constellation 822, class of '54, floated on an air cushion too, and was an excellent machine. Other models (see the link above) followed. An aunt, "antique dealer" (sic) used to sell these second hand, and to demonstrate had one wired backwards, so that it would stick to the ceiling - until one day it brought the house down!

They used this principle to build hovercraft for Mythbusters. If I could get my little Roomba to float around that would be great; a little floating robot vacuum would be to geektacular.

How well does your Roomba work? We need a vacuum and I'm thinking of going hi-tech. Most of the floors in my house are hard wood, with a few area rugs.

It works really well. We have a mini-dachshund and he would get under the sofa and other small places and come out covered in dust bunnies. Getting the Roomba helped with not having to move the sofa ever week to vacuum. It handles rugs better than I expected, it takes care of all but our shag carpeting. It's dust bin does fill up quickly though, you have to dump it out every room and recharge it. One or two rooms a day is the best that you can do.
Over all I give it a 4 out of 5 stars =)

Is the Roomba bite-proof? One of my pups likes to show our old-fashioned vacuum who's boss. :)

Don't know. It is Frisbee shaped. Our runs for the hills whenever it comes out.

Get a bigger dog or a lower couch! :-)

Not traiding in my little Doxi for anything =)
Cute factor 5.

And I wouldn't trade my doxy, either, not even for a dachsy . . .

A hovering lawnmower introduced in the '60s. It was electric powered. A friend who had one told me that while they were very easy to push, you tended to get sore muscles in your torso because all of the turning was done from your waist, unlike conventional wheeled mowers which you tilt and pivot on their rear wheels.

Flymo is still in business (although apparently not in the U.S.) and still makes a hovering lawnmower.
