Summary: Worse vacuum ever. This vacuum is junk, it overheats often and yes I keep the filter clean. The dirt clogs the tiny holes in one of the parts and it needs cleaned too often, but if you don't then it won't run. Plus cleaning everything is very messy with dirt getting everywhere.
Summary: I love the suction of this machine. Was surprised that Panasonic made vacuums and have been pleasantly surprised. The compartment for debris is easy to empty and the power cord is nice and long;. The only reason for not giving it five stars is that I wish the attachment cord was longer.
