Bests & Worsts Reviews from Amazon

First and foremost - I am guessing that some of the positive reviews are not for this model, from "robots", people who have received this item "free" or people who literally use this vacuum for less than 1 minute of work each time. It is virtually impossible to get any accurate, detailed specs on this unit anywhere including the manufacturer's website - there are no specs at all on either the capacity of the battery, the run time under full load or actual suction power of this unit. It is beyond bizarre and the only clue offered is the AW rating of 16 which is generally meaningless if not in context with battery capacity and run-time. I had to search high and low to come up with some comparisons and then shockingly a mid-range, handheld Dyson has an AW of 100 while this machine has an AW of 16. A mid-range, handheld Dyson runs on full load for 20 minutes at 100 AW, this machine runs for less than 2 minutes at 16 AW (my own approximation as best as I can make it out after a 24hr charge cycle) and that's if you're very thrifty with turning it on and off throughout your work. Another point of reference, a Hoover Air 20V goes 25 minutes at full load and 50 minutes with extended battery drawing approx. 20v. Also, there is no pre-filter in this unit, and the filter inside is a less than well made, thin and easily wearable, cloth/blended materials filter which means it will start falling apart quickly and you will quickly need extra filters especially if you're picking up pet hair that has a tendency to get tangled. This B&D is a "busted dustbuster" - a high discharge device (draws 10.8 v) with a low capacity battery (2 cell of unknown capacity) which equals very, very short usage - and - a "drip" charger that makes for an extremely long charging time. It's a piece of junk with no light indicator (or any indicator) as to whether it is charging and when it has completed. I am very frustrated for having purchased and then returned it, and I am equally disappointed that this manufacturer has gone to such low standards on what use to be a fairly reliable brand.
