The secret of better suction: Hypercone[tm] Air Flow System

RY4000 uses patented HyperCone[tm]technology to ensure optimum suction and performance even when the bag is full.

Patented innovation to give you a great
day every day with RY-4000

A transparent dome lid allows the user to easily see when they need to empty the cleaner. The Back Pack can hold up to 6.4 quarts of dirt and debris! Less emptying means greater efficiency.

Patented Hypercone™ technology provides these benefits:
- maximum suction at all times, so you never have to retrace your steps
- consistently high air flow resulting in longer motor life, less wear on electrical components, and reduced service requirements
- high airflow filter also helps the unit stay cooler, thus reducing heat on the back of the user

The Back Pack Vac also comes equipped with a filtration system that traps 95% @ 0.3microns of dust and allergens. That means greater relief for allergy sufferers. Add conversion kit for additional Hepa filtration.

The Royal Back Pack Vac is tough and durable. It has a polypropylene frame, which allows for a longer, cleaner life. It can also handle extended daily use and the wear and tear that comes along with it. A 50-foot power cord with rubberized cord restraint, that helps prevent cord pullouts, allows for continuous powerful cleaning and to top it off it doesn't blow paper off desks!
