You know, this machine has a lot of potential. It has a better extendable brush design than its red predecessor(s), a nifty fold-down nozzle, and an easier-to-clean filter/dirt bowl design. But it often ran out of power quickly. My pet peave with manufacturers of cordless hand vacs is that they continue to use Ni-Cd and now I guess Ni-mH battery packs. Lithium, though more expensive, would be a much more efficient and effective power source. Mine had Ni-Cd, and they run out of power quicker and have a much shorter lifespan than any other. At Christmas I went to use the vacuum and noticed the red charging lamp won't even come on - 4 years old (out of warranty) and deader than a doornail. I don't know whether it's the battery pack or the charger unit, but either way it will cost as much to replace either than to buy a whole new unit. I will have to see what Batterys + wants for a new pack, but in the past they were about $17 for a 3-pack assembly; this vacuum uses 13, not 3, in its pack. It's likely to be cost-prohibitive. And a couple of years ago it refused to stay on its wall mount, so I used epoxy to reinforce the miniscule plastic bumps on the mount to which the vacuum was supposed to catch and hang onto. That was one of the most wimpy, useless designs I've ever encountered. The vacuum body easily fell off the wall mount/charging unit, crashing onto our bathroom countertop; the charger/mount had to be flat on the counter top for the vacuum to properly engage the little, springy plastic retainer tabs at the top of the mount; hanging it on the wall as intended just wasn't safe. Miniscule bumps on the end of each of two tabs was all that hangs onto the entire hefty vacuum - ridiculous. And proper fixation between vacuum and mount is required for good contact with the proximal springy metal charging contacts. One tab had broken off, so in the process of reattaching it with epoxy, I beefed them up and micro-formatted their edges so they would neither snap off nor let go of the vacuum quite so readily. It's almost sad. Some engineer designed the basic machine pretty well, but the charging/storage side of it sucks (no pun intended).
