I've never owned a cordless vacuum before and wasn't quite sure what to expect. Once took the components out of the box (there are 3 pieces that click together. The base, the body, the handle) and the cord, it was very easy to assemble. Instructions say for optimal use, let charge for up to 6 hours. When I plugged it in, I see a charging indicator by the power button. It's easy to see in a not too blinding blue hue and let's you know how long til a recharge is needed. After the charging was complete, I started to use it on my carpets and throw rugs. It's so light weight that it didn't pull up the throw rugs either! The vacuum glided and maneuvered smoothly and made a nice transition to carpet. Mind you, I had vacuumed previously 2 days before and yet this little guy picked up a lot of dirt and pet hair left behind. If you're looking for a simple, no frills, lightweight yet heavy duty pick up vacuum, this one's for you!
