Bests & Worsts Reviews from Amazon

So I've actually owned two of these. My teenagers are in charge of cleaning the floors in my home and requested a hand vacuum for the stairs. I picked this one after looking at a few features and it seemed fine. With the first one the beater bar quit working around 4 months in. I figured, anything I give to teenagers, I have to expect they will break. Tossed it and ordered a new one. The second arrived and I was using it to cleanup a sofa; it had never been used for anything else. Beater bar stops working on it. At that point I break out my tools and pull it apart. Man was I shocked at what I found inside. A small 12v AC/DC brushless motor with no cooling and no gearing runs the beaterbar. If you aren't an engineer, tiny toy $10 race cars have motors like this. It was attached to the beater bar with a small plastic wheel and a rubber belt. The plastic wheel is NOT keyed to the motor and the motor drive shaft can freely spin inside the wheel if anything should cause it to stop spinning (like something binding the beater bar). This would cause friction, and the low grade plastic used to make the wheel heats up and melt. At that point it no longer holds friction and thus doesn't spin the beater bar. So what caused my beater bar to bind? Hair... not a lot of hair. When I removed it, it was maybe a ball the size of a nickle. At that point the bar spun again but I was curious and took a business card and ran the brushes against it. The business card was able to halt the beater bar. To be clear the motor wasn't able to bend a cardboard business card. It has NO torque at all. I considered that the small plastic wheel driving the belt had been bored out and the motor may be spinning. I could fix it with glue maybe. But then again as I said the motor was crap to begin with so even if I did that it would likely just bind the motor and burn it up. It's not vented at all so in the right (admittedly rare) conditions could cause a fire if I did that. Not worth it. Long story short, the guts of this thing consist of toy parts and bad design. It WILL fail inside of 6 months if used as little as 15 minute sessions once a week.
