We have a new vacuum cleaner. It is a Simplicity and it was purchased at Stark's Vacuums in Beaverton, with the help of Ben, our friendly sales person.
I'd like to say thank you to all of you who have provided input on this decision.
We reviewed the consumer reports testing results and were deciding between the Kenmore Intelliclean (about $250 on sale) and Eureka Boss (about $140 at Costco). On my way to Sears to check out the Kenmore, I decided to stop at Starks, the local vacuum dealer, and see what they had to offer. Ben immediately directed us towards the Simplicity lines.
For $350 we have a reliable machine with a 7 year warranty and the first 3 annual tune-ups included. I expect it to outlast the warranty.... but nice to know that it will at least be around for that long... and it's light enough that Noah can push it.
