Just FYI, currently the best vacumm cleaner in the market is come from Dyson, UK company, manufactured in Senai, Johor. However the price is not affordable to most of the ppl in Malaysia.

Some said bagless will need to clean the filter occasionally to avoid suction loss, basically this is due to poor separation they designed in the machine. Cyclone is the Dyson patented technology 20 years ago that basically patent expired nowadays so everyone is able to copy and use the name now. Unfortunately some can't master the separation technology correctly and causing some degree of debris bypass the bin and stick to the pre-filter hence suction loss. I have a Dyson cylinder vacumm cleaner that used for clean my new house after renovation, sucks all the concretes, wire stray, left over cement dust and alot of fine dust without clogging and lose suction even the bin is full.
