Practical Motorhome reviews the Philips FC6091/01
This model powered through the flour and sugar and was one of the best at cleaning up the corn flakes. After a while it got clogged, but it just needed a bit of a poke to clear it. To empty it, simply pop off the front section by pressing a small button at the top, then pull out the filter. The front nozzle can be removed for a more-thorough clean. The unit also has a HEPA anti-allergy filter that traps fine particles, so it is good for allergy sufferers. Price, performance and ease of use make this a winner.
