Ultra-fast Gravel Vacuum

Those of you with aquariums hopefully know what a gravel vacuum is. A rigid tube with a piece of flexible tubing attached, that one starts a siphon in, then sucks up the gravel. The gravel gets pulled to the top of the tube, the old food and poop go out the top into a bucket, and the gravel falls back to the bottom. However, it's very hard to get around all the ornaments and such. It takes a long time, especially when you have fish biting your arm. The Ultra-fast gravel vacuum would be a rectangular box, that comes in different sizes and shapes to match the bottom of your aquarium. It would have a grid inside, that one pushes deep into the gravel after removing everything in the way for its cleaning. The vacuum would be about 5 inches tall, to give the gravel some space to float up. The tube would have a larger diameter than present gravel vacuums already have, and the siphon would be started and stopped by an inline squeeze pump with valve. It would also have scrubby things on the sides that scrub off the algae, to save you another step.
