I had no difficulty navigating the stairs and I found that I could work the carpet nicely.
Back in the day I ran that vacuum hard 6 nights a week for years with no issues.
We hope you found these Panasonic vacuum cleaner reviews helpful.
My old kenmore had a manual carpet height adjustment.
The last difference was the old kenmore had an access cover that allows you to open and remove any larger debris that didn't quite make it to the bag.
Such a great design - simple where it should be - like changing the bag, or pulling out the hose.
