The MC â€“ V9644 canister Panasonic vacuum cleaner is one good looking appliance that has the “Positive Drive Brush System”. This feature will tell you if the floor is clean or not. Â In this way you will be quicker at cleaning because you will know where to begin and where to stop. Also, this vacuum has a triple micron filtering system which helps to keep dust out of the air. The full bag indicator is also great, plus the four position height adjustment and a headlight. On the handle you will find a switch to turn the power-head on and off and this is very convenient. Some people also complain that the suction is appalling but you can decide that for yourself.
