There are a couple of design flaws. One is the fold out cleaning nozzle. It is very difficult to turn around and lock into place. And you can't leave it locked in place because then it won't fit on the charger. When I try to unflip the nozzle the whole thing comes apart and spills all the dirl I just vacuumed up. Basically it works but getting it set up to use is a pain. If you are like me when you grab your hand held vacuum you are in a hurry to clean up a mess so it's not fun to have to struggle with it first. You don't have to flip out the nozzle to use but it really helps to get detailed cleaning in crevices and to not have to bend down so far. I haven't had it long enough to tell how long it holds a charge or how well it really picks up. It seems to pick up ok but I haven't cleaned the car - a true test.
We've been DIY renovating and I knew I needed a hand-vac. I've had mixed experiences with them, but this one seemed pretty strong and appropriate for our wood and tile floors. It's quite powerful and the battery lasts a decent amount of time- enough for the quick messes you usually would use hand vacs for, certainly, and I've used it to clean every space between freshly-laid mosaic tile in the bathroom before grouting, which was probably a 7-10 minute process. The battery lasted for the whole process and it picked up all the little bits and pieces down between the tiles with the assistance of the skinny nozzle attachment. I also like how the attachments are attached at all times- you just flip a switch or press a button and they're ready to go. My only slight issue with this device is that the 'release' button for emptying is very close to the 'on' button- no mishaps yet, but there have been some close calls!
I bought this for light clean-up around the house and the car. Suction isn't that great, and the battery charge barely made it through vacuuming one car. Does a good job with dirt piles after sweeping the tile and hard-wood...not enough oomph for dust or dirt on carpet.
This is a good little vacuum if you have hard substances that you need to get up. It does not work well with pet hair. There is a filter inside that is impossible to get completely clean and grosses me out eveytime I have to knock all the pet hair off of it. I would have preferred a bagless handheld without a filter.
