This is the worst vaccum i have ever had. First of all, the top filter needs cleaning after almost every use. Secondly, dust chokes the dust tunnel every now and then, needs cleaning. Now the roller has stopped spinning , on examining it, i found, the plastic edges had melted, causing a tilt and now it gets stuck reducing the suction and fumes because of friction between belt and pulley.I use it not more than once a month and this is what i have had to put up with since the beginning.I won't suggest anyone to buy this product.
