The vacuum is easy to assemble right out the box. I had to charge it for 6 hours prior to using as instructed. The charger is stored away in its own compartment on the back of vacuum. I love how easy it is to handle, that it is cordless and it's not heavy. It does although lack some suction power. A fully charged battery doesn't last very long. The filter is easy to clean, just rinse with water and let it dry at least for 24 hours. It is hard to remove hair from the roller, unfortunately it is not removable that I could see or find. The detachable handheld vacuum is nice to have to clean corners. It doesn't take much storage space which is a must for me. Its packaging is appealing. Overall it's a nice vacuum for small clean ups.
