I received the sweeper last night, charged it overnight and used it this morning. The charge lasted long enough to sweep my entire apartment (a small one-bedroom) and the dry cloth and filter were very dusty and dirty. The filter even had some small scraps of paper and a small plastic piece of a broken toy. So, I am very pleased. The suction is good, the charge is sufficient for me and it picks up a lot of dust and hair and dirt.
