Find the Sandia 74-4003 On Vacdepot!
Product Specifications
Our HAUS HEPA series backpacks give the homeowner the same performance and durability given to the commercial backpack user with an added touch of convenience and flexibility. The XP-3 Whisper HAUS HEPA adds certain efficiencies that are lacking in full commercial models when used in the home. Unlike other backpack brands, our commercial and residential models both get the same high performance motor and are built of the same quality materials.
The XP-3 Whisper Raven HAUS HEPA 74-4003 is a customized model of backpack brought together by the vacuum professionals at Vacdepot. Starting with the base XP-3 Whisper Raven backpack from Sandia, Vacdepot packs this residential version with our own custom tool set and accessories from the world's best manufacturers. We know the tools and attachments that work well for commercial cleaning of restaurants and warehouses are not so wonderful when you try to use them in the living room. Our goal was to find attachments more suited to use in the home or small office that are easy to use, well designed and also match the performance and style of the XP-3 Whisper backpack.
The result of years in design and production: The Sandia XP-3 Whisper Raven 6 Quart backpack vacuums. Technologically advanced vacuums with the durability you expect from industrial cleaning products. Committed to continually innovate better products with new designs and better performance, the Vacdepot Special Edition Raven Backpack vacuums' designs make good sense, and good value for demanding cleaning applications. The maneuverability and strong suction of the XP-3 Whisper Raven makes for remarkably efficient use of your vacuuming time, letting you move freely from one surface to another and one room to another using the same machine and changing only the tool (which stores on the harness) to complete your task. With a Raven Backpack vacuum you can eliminate bulky canister vacuums, heavy uprights that cause strain, and dry brooms which create airborne dust that must be cleaned again. The XP-3 Whisper Raven 6 does this at a lower noise level than any other in it's class, lessening wear on the operator and lessening the time required to clean. The XP-3 Whisper Raven 6 HAUS HEPA model 74-4003 is a high filtration, high performance model with straight suction tool set for cleaning in residential and light commercial applications by most any sized operator. The lightweight, low noise design is great in busy homes or offices of large or small design. The tools included with the XP-3 Whisper HAUS HEPA are well suited to cleaning above floors, hard floors and some areas of low pile carpeting, smaller area rugs or throw rugs. The XP-3 Whisper Raven 6 is also available in other configurations from Vacdepot.com including the full commercial WERK Series with rugged over-sized commercial attachments, NON-HEPA filtration WERK and HAUS models, and our new TURBO series with dedicated carpet-cleaning tool. Our best selling backpack vacuum is also our most versatile with many models available to suit your specific cleaning needs.

Some custom components of the Vacdepot models are sourced from the world's best manufacturers including Soteco attachments from Italy, Wessel-Werk attachments from Germany and Woods Electric, provider of the Cold Flex© power cable from the USA and Asia. Quality assurance is part of every machine built by Sandia Plastics, and your satisfaction is guaranteed with each purchase from Vacdepot.
Sandia is the only backpack manufacturer to use the double fan motor in a backpack, making the XP-3 Whisper 6 a quiet lightweight backpack that works better in sound sensitive areas, including the home, than other brands and styles of vacuums.
The 115923 Ametek motor is not only one of the best performers in its class, it is also one of the strongest built styles Ametek makes. The 115923 is an all metal motor with a cast aluminum base plate and commutator end frame. Both ends of the armature have sealed 8mm ball bearings and the twin precision aluminum impellers are crowned with steel covers for protection and stability. The same motor is also used in expensive consumer vacuums that retail for over a thousand dollars and is respected in the industry as a top performer.
In a vacuum cleaner, particularly those that must pull the debris through a hose or tube, it is a combination of CFM and Suction that does the cleaning, and AirWatts is a measure that can be helpful in finding a powerful vacuum cleaner motor. Another important measure of a vacuum motor is its normal operating speed. A vacuum motor's RPM is strongly tied to its longevity. As with any motor that you would like to last longer, slower is better. The XP-3 Whisper double fan system allows the motor to get more work done with fewer rotations per minute. Aside from the increased motor life are also less heat generation and lower noise, both great for vacuum and user alike.
If that was all Sandia did to increase the airflow of their vacuum it would be a great machine: comparable to, or better than, any other backpack vacuum on the market. However - Sandia's commitment to the single most important aspect of a vacuum's performance goes far beyond a high performance motor, it is at the very core of the Raven's design.
In a conventional cylindrical backpack vacuum when the bottom of the bag fills with dirt, the air begins to travel through the sides of the bag and down to the motor. As the bag grows in size filling with debris, it contacts the sides of the bag housing and top of the motor effectively "cutting off" the path of least resistance, and the air must once again travel through the dirt slower and slower as the bag fills up. Slower air through the motor means slower air through the tool and less pick up performance - all leading to more time cleaning. We have all experienced poor performance in vacuums due to full bags cutting off the suction. In a backpack vacuum this is made even more critical by the top-fill / motor under design. A full and sagging bag can dramatically cut off airflow as it seals off the motor from incoming air.
Adding to the high airflow efficiency the HEPA filter is dome shaped to prevent the bag from sealing against the motor as in regular flat filter machines allowing a more consistent airflow. This single design advantage alone allows Sandia to offer a 5 year motor warranty on all backpack vacuums because the motor runs cooler. Heat is not only the number one vacuum motor killer, it also makes the vacuum run louder and less efficiently making it uncomfortable to use. The HEPA Raven runs cooler, quieter and more efficiently than other brands of HEPA backpack vacuums with similar performance. If the tapered design is superior why are other backpacks cylindrical? The old round backpacks were the first design because they were easy to build, literally a piece of PVC tube with a motor glued in one end, a cap with hose on the other and a harness riveted into the middle of it. They were a simple design that was easy and cheap to manufacture. Sandia broke the trend of tubular backpack design with its unique hex shape and built in contoured backrest for both added performance and comfort.
Next they designed a special filter; a filter not for dirt, but for noise. The Dual Cell Noise Filter included on Sandia's backpacks features air control channels cut from open cell foam with large pore capacity to diffuse the exhausting air and sound from the high air-flow motor.
Just like a muffler on an automobile, the Dual Cell Noise Filter breaks the air into many streams, changing the direction of the airflow column and blocking the exhausting motor noise in the process. The Dual Cell Noise Filter press-fits into the bottom of the vacuum on top of the motor protection plate, which keeps the filter from entering the motor's spinning armature. It is easy to remove if needed, and can be rinsed in the sink with tap water if it should collect any fine particulate. Further fine tuning the vacuum to reduce noise, Sandia went about eliminating extra parts and pieces that can vibrate and make noise. An effort was also made to build the vacuum of noise insulating materials and to gasket parts of dissimilar materials so they cannot rub together.
Contoured to fit the natural curve of a human back, the molded backrest coupled with the quiet design makes the Whisper Raven comfortable to use even over long cleaning sessions. Flared and tilted at the hip, the Whisper Raven's backrest puts the weight on your larger leg muscles and not on your upper back. A built-in closed cell foam cushion keeps hard plastic plates off your back, and the open air space inside the backrest provides distance between you and the heat of the machine. Sandia also molded a carry handle in the top of the backrest that doubles as a cord hanger when the vacuum is not in use.
The left side of the waist strap has three elastic loops to hold the crevice tool, dusting brush and upholstery nozzle for quick conversion to above-the-floor cleaning. The Sandia backpack harness system has NO bolts to fall off, no spacers crack and break. Simplicity in this design not only makes for a more durable vacuum, but a more user friendly one too.
The lid of the Whisper Raven 6 features a plug-in straight cuff connection. The tapered connection provides a positive lock between the hose and vacuum, eliminating separation of the hose while you're cleaning. The Raven 6 lid is a quick connection 1/4 screw top that is easy to remove and simple to reinstall with oversize thread connectors and a single piece design that is lightweight and durable. With no latches to wear out the screw top design will last the life of the machine and provides a positive seal each time a new bag is installed. The hose is removable from the lid, making storage and transportation easier as well.
The inside of the Raven vacuum holds the 2-stage micro-lined bags, 2 layer cloth bag made from Kimberly Clarks© finest vacuum cloth and the dome-type HEPA filter. Together this quad-level filtration system is capable of filtering 97% of all particles down to 1 micron in size, adding the HEPA filter brings the filtration up to 99.97% at 0.3 microns, further reducing airborne allergens and eliminating the "after vacuum dusting" required with most other commercial vacuums. The HEPA Raven not only picks up the dirt well, it keeps it well too.
Controlling the XP-3 Whisper Raven is simple with a single power switch. The on/off switch is recessed into the lower flange of the backrest where it cannot be bumped off by accident and is still easy to reach when needed. The entire vacuum housing is composed of only 3 parts, all of which are made of rotationally molded polyethylene. This same material has served Igloo© cooler company well for years and works even better for Sandia, making the vacuum body lightweight and nearly indestructible. Built for heavy use, Sandia designed this vacuum to take tough service with little maintenance.
The Whisper Raven 6 hose has a vinyl connector that friction fits into the tapered cap. Our HAUS series hose is 5 foot in length, a perfect fit for backpack users of any size. The hose material is a durable smooth bore with a soft outer threaded design with rounded edges that do not scratch or pinch while you're wearing the vacuum. The hose tool end, or Bent Control Tube, has a threaded swivel cuff that keeps your tools from getting tangled while you clean. The bent control tube is 15" in length, made from durable chromed steel, has a standard friction fit that is easy to use and a three position suction regulator. All above the floor cleaning tools can be used directly on the bent control tube or at the end of the telescopic extension wand. The friction fit makes for quick mount & dismount with no latches or pins to break.
The new telescopic wand is color matched black with the other tools in the kit and adjust fully from 22 inches to 39 inches in 1 inch increments. The latching mechanism is a positive ratchet giving a firmer lock into the desired height allowing the tool to be resized on the fly for the user. The latching system is internally sealed from the dirt control tube for perfect air-flow with no catches and the hose end features nylon collar for quick and easy connections. Imagine cleaning stairs with a compressed wand that does not require you to hold your arm up to vacuum - less fatigue and much safer. Cleaning overhead is also easier due to the lower weight, comparable to plastic with 10 times the strength.
The cleaning face has been shaped for the way people clean, with a five inch cleaning depth and a 1.5 inch protected opening. The elongated service end of the tool has nearly twice the cleaning area of standard dusting brushes, letting the user do more work in a single pass. The top of the Ultimate Dust Brush is also tapered and the bristles are swept forward letting you clean into corners and reach areas inaccessible to other tools, and the suction opening is tapered so suction is evenly distributed the whole length of the tool.
Our unique crevice tool is 13" (330mm) long with flat profile and slots for those "hard-to-reach" corners and crevices where dust and debris can hide. Slots provide additional airflow along the cleaning surface underneath furniture and cabinets. Made of textured ABS plastic the crevice tool is strong enough to take abuse but also just a bit flexible to keep it from breaking. All the above the floor cleaning tools can store directly on the backpack's harness in elastic loops to keep them close at hand.
We look once again to Wessel-Werk for the Whisper's amazing combination floor tool. The RD294 is adjustable, built for use on all textile and hard floor coverings and has a cleaning width of 11.5 inches. Using this tool will allow you to clean carpets, rugs and throw rugs of any type and all hard floors - utilizing the high suction of the vacuum that is evenly applied to the floor by the unique design of the tool. A large centered opening allows for maximum airflow through the tool directly to the surface. This suction is carried to the edges with deep "V" shaped grooves, ensuring constant airflow for any texture of soft flooring. There are also two independent liter pickers on the cleaning surface to help capture threads or lint that may be stuck in the carpet.
The great design of the tool makes it easy to use. Wessel has also engineered many labor saving features into the tool as well. At the center of design for the RD294 is the large centered roller wheel. This soft texture wheel is important to both functions of the tool: making it easy to glide on hard floors - using its convex shape to track straight, and keeping the brush from "digging in".
The RD294 not only looks beautiful (we have seen many floor tools in our time, this one IS beautiful!), but is also built strong. The outer housing is durable polypropylene with a textured surface that won't mar your walls and cabinets. The base plate is nickel plated steel with recessed screw heads that will not damage floors.
Unlike conventional upright or canister vacuums, Sandia backpack vacuums use external power cord extensions for providing electricity from a standard 120V wall outlet to the vacuum. Each vacuum comes equipped with a 12-inch pigtail cord attached at the base with a compression style flexible cord nut. The short cord adds to the mobility when moving the vacuum from one job site to another but more importantly promotes reliability of the main vacuum by making a common problem of all vacuums external.
The Cold Flex© compound power cord also adds to the usability of the XP-3 Whisper backpack with excellent flexibility, 30% - 50% more flexible than standard vinyl compound orange cords, and superior abrasion resistance. The Cold Flex power cable is ready to clean when you are and remains flexible in any weather. In freezing weather the cord will not crack in down to -58°, and will not deform in temperatures up to 140°. The Cold Flex outer cover is SJTW rated, designed to meet OSHA specification, UL, C-UL and CSA listed and features excellent abrasion resistance for extended usage without wear. The Cold Flex cord is blue in color which more closely matches the equipment colors and also does not show dirt as easily. Both plug ends of the Cold Flex are solid and molded directly into the cord jacket for excellent durability.
The 74-4003 XP-3 Whisper Raven 6 HAUS HEPA is premium backpack model for residential cleaning with enhanced filtration. This model, as are all models in the HAUS series, is centered on providing the right tools for residential cleaning applications and the special tasks that home vacuums are often asked to perform. Our many years experience in backpack vacuum sales at Vacdepot has led us to couple the excellent Sandia XP-3 Whisper suction body with the best tools and attachments for the home user. All of the XP-3's components are matched with one another, and the entire unit is matched with the job it is to do in the home. Who should not use a back pack style vacuum cleaner? Back pack vacuums are best suited to cleaning applications where it will be operated in a continuous block of use. The exceptional mobility of back pack vacuums with over 100' of cleaning reach is most efficiently used when all vacuuming is done at once. If your cleaning application or method requires you to frequently stop to perform other task, then return to vacuuming off and on during a cleaning session then the action of mounting and dismounting the back pack will negate the efficiency gain of cleaning with a back pack vacuum. Also, those whom must clean in tight and restrictive spaces may sometimes have trouble using backpack vacuums. And despite their low weight, users with back problems should not use a back pack vacuum. In some cases use a HIPVAC such as the Sandia HIPSTER may work in applications where the full size XP-3 back pack can not.

This model of XP-3 gives you HEPA filtration and special quiet design to provide the ultimate in user comfort for cleaning in the home. The XP-3 Whisper Raven is a pleasure to use not only because it is quieter, but also because it cleans better. A real alternative to bulky canisters and heavy uprights, the XP-3 Whisper Raven 6 HEPA Backpack with HAUS Series tool kit provides superior cleaning, and excellent maneuverability in a very durable design.
The Sandia XP-3 Whisper Raven 6 is everything we have come to expect from the modern backpack vacuum: Strong, Durable and Easy to use. Sandia's backpacks also offer advanced features to make vacuuming floors and above floors faster and cleaner. All Sandia backpack suction bodies are designed, tested and built with pride in the USA by Sandia Plastics of Huntington Beach, California. Other components including the Micro-Filter bags and Micron cloth bag are also made in the USA.
What sets this model of Sandia Raven apart from others is the XP-3 Whisper 2 stage low RPM motor for the lowest sound levels and lower heat generation. Sandia uses model 115923 double fan motor from Ametek-Lamb, the world's largest manufacturer of series motors for portable vacuums.
The dual fan Ametek-Lamb 115923 suction motor used in the Vacdepot XP-3 Whisper series from Sandia creates the most powerful backpacks available even though pricing remains comparable to standard backpack series. Vacdepot has chosen to offer only the XP-3 Whisper motors in our 6 and 10 quart backpacks because of their superior performance and longevity.
Air watts is the combined measure of motor performance factors including Cubic Feet /Minute Airflow, and Sealed Suction. A vacuum motor's CFM (Air Flow) is the rated volume of air the motor can move in cubic feet each minute. The Sealed Suction is the measure of lifting or suctioning strength the motor can produce and is represented in "inches of lift" by measuring the height a motor can lift a column of water in a testing tube.
Far from the disposable and import motors used in so many other models, the 115923 motor is made in the USA, is designed for years of trouble free use and includes an outstanding 5 year warranty from Sandia. Maintenance of the XP-3's motor is simple and can be performed by non-technical personnel.
All vacuums perform at their best when they are new and the bag is empty, the true test of performance comes as the bag begins to fill with debris. As the bag fills and increases in size, air tries to find its way through or around the debris to get at the vacuum (negative pressure) created by the motor. The fastest way for the air to move and give the best performance for cleaning is through the filter media - the point of least resistance.
Adding to the vacuum user's comfort while cleaning is important when you change from a traditional upright to backpack vacuums, and the noise level of a machine that is used in such close proximity to your body is important. Reducing the noise pollution of backpack vacuums was a top design goal with the Whisper 6, a tough task considering that Sandia backpacks are already some of the quietest vacuums in the industry. Sandia started the noise reduction process with unique waffle foam wrap in the motor cavity of the XP-3 Whisper Raven that added over 70 inches of sound deadening insulation to the vacuum. The foam wrapping both isolates the noise and vibration of the motor from the vacuum cavity and also helps to reduce exhaust noise from the motor.
The harness is made of durable nylon with overstuffed cushioned pads at the shoulders and waist. With a large degree of range the backpack fits most any sized person, and adjusting the harness is easy with a four-point strap pull. The upper padded shoulder straps have a quick release one-hand tension system with sternum strap and the waist strap has only a single buckle.
The Sandia XP-3 Harness was updated in early 2004 with new over-stuffed shoulder pads for extra comfort, new style grommet rings to prevent wear and a sternum strap with buckle for the shoulder straps. The new sternum strap keeps the shoulder straps from separating and sliding off. It is particularly helpful when your cleaning task requires you to bend into positions, climb up ladders or crawl while wearing the back pack.
The Whisper Raven 6 HAUS HEPA model includes a unique 1.25" (32MM) straight suction tool set for cleaning hard surfaces from ceiling to floor. A vacuum's tools are one of its more important but often overlooked aspects. It is here that the vacuum meets the dirt and the Whisper Raven 6 Haus includes the best tools available to take heavy use and last for years.
The Haus series of tools are both smaller in diameter and lighter overall weight than the commercial Werk series tool kit, and much more user friendly for use in the home. Our wide body tool set maintains high airflow to complement the Whisper Raven's motor. The 15" bent control tube has a swivel connector that comes installed in the Whisper's hose cuff providing 360° flexibility and easy removal for storage or transport. The bent control tube allows the use of straight suction wands instead of the bulky "S" shaped commercial wands, giving you better control while cleaning without the hassle of a large cumbersome wand-set. Taking the bend out of the wands and putting it into the grip makes the commercial style backpack usable in the home environment.
NEW! Aluminum Telescopic Wand
Our Haus Series three piece above-the-floor tool set also includes some of the most durable and unique tools on the market. The dusting brush used on the Whisper Haus is made by Wessel-Werk and is one of the most popular aftermarket tools on the Vacdepot website. Named the Ultimate Dusting Brush, this one tool has addressed many deficiencies of regular dusting brushes.
There are 68 individual tufts mounted in a double offset row to the chassis with raised connectors to hold the bristles securely to the tool. The soft bristles are longer to flex as the tool passes over the object being cleaned, using stored tension in the bending bristle to knock dust particles off the surface and into the air stream. Spacing between the tuft mounts allows for easy cleaning of the tool itself. Removing threads or hair caught in the bristles is simple to do and keeps your tool working with optimum performance. The poly bristles and heavy duty housing are also water washable and it fits easily in the top rack of your dishwasher.
The deluxe vinyl upholstery tool is 6" (152mm) wide with scalloped insert and grooming brush. The shoe design insures continuous air-flow without the need for a suction reducer, eliminating "seal off". The brush strip gently engages upholstery to lift debris and groom surfaces.
The soft outer cover will not mar light colored furniture or scratch soft surfaces.
Using the tool on hard floors requires you only to move the toe operated switch, releasing the hard floor engaging bristles. The polypropylene bristles are strong enough to clean any hard floor surface from tile, wood, linoleum and down to concrete. The bristles are packed tight to give the tool a firm base and are even wrapped on the side of the tool, not just front and back. The bristles on this brush are scallop cut with slots on the brush surface to let dirt into the air path of the vacuum, not knocked along front of the brush like a broom.
And for use on carpet it transfers your forward motion directly to the floor so you do not have to fight the resistance from the bottom plate to the surface. The RD294 also has a full swivel, triple action joint, making this tool the most flexible available and ensuring optimum contact with the floor from any angle. Finally the top mounted toe switch is large and textured with grips that make it easy to use.
Another Vacdepot exclusive and new for 2005, all Sandia HAUS and TURBO backpack vacuums (only when purchased from Vacdepot.com) will include the Woods Cold Flex 16 gauge, 3 wire, 50 foot power cord.
With an external extension cord, any damage to the cord can be solved by simply unplugging the extension cord and using a new one. Gone are the days of having to lug your vacuum into the repair shop so they can dismantle the unit and install a new cord. Gone also are the days of waiting for the repair shop to replace the cord and the high price of new cords.
The Cold Flex power cord, just like every other part of the Sandia XP-3 Whisper Raven 6 HAUS HEPA backpack from Vacdepot is designed for performance and convenience. Whether you use the XP-3 to clean your home, small office or you carry the vacuum from home to home for maid services, you will find our system powerful, reliable and you will realize an exceptional return on your investment.
Vacdepot also offers the HAUS series for light duty or special application commercial work or residential usage. The HAUS series also includes derivative models, TURBO for cleaning areas of carpeting in the home and soon the POWER series equipped with electric brush. Special order 400Hz models are also available for cleaning cruise ships and aircraft with special power requirements. Along with the many advantages of using a backpack vacuum in your business or home, like faster and more effective cleaning, the Sandia XP-3 Whisper Raven 6 adds many unique features not found in other products. Backpacks have gone from a cleaning concept to an indispensable tool in the cleaning arsenal, and the Sandia Whisper Raven expands on the advantage of user and machine as one with a vacuum that provides maximum value, minimum noise.
