At the age of 93, I favor appliances that do the job they were designed for without any fuss or turmoil. I bought my first Zing some years back. When it appeared to stop working recently, I ordered a new one. I hated to abandon the old one and decided to check to see if the hose was blocked or if there was something amiss with the dust bag. Wonder of wonders, it works just fine! I can't use two Zings in my small condo but I have a grandson who can use one in his apartment in Brooklyn.
