Alpha-F / Vacuum Cleaner


Alpha-F is a F-shaped handy vacuum cleaner using cyclone-modular engine. The cleaner is composed of a main body and a modular engine. The vacuum cleaner market has the trend of launching new products every 2-3 years with subtly altered design and slightly refined performance. However, consumers can't afford it whenever the new product is released. As Alpha-F has two engines: a main engine built in the main body and a modular engine which is detachable, consumers don’t need to buy new cleaner that is just released. Alpha-F has the advantage of letting users to use the cleaner as new by simply combining the new modular engine to the main body.
