Common Questions and Answers

This section will provide answers to common questions about ultrasonic blind cleaning. 

Question:  "How fast can a Zenith ultrasonic blind cleaning system clean a venetian blind?"

Answer:  Our top-of-the-line COMET blind cleaner can clean, rinse,  and dry a typical venetian blind in 3 minutes or less, ready to re-hang, without ever opening, depending on how contaminated the blind is.  Our less costly BASIC ultrasonic blind cleaner can perform the same task in 5 minutes or less, but may require that the blind be opened somewhat.  The COMET, with Zenith's patented CROSSFIRE Ultrasonic System (US patents 5,865,199 and 6,019,852), can do this with the blind closed, a feature not possible on ANY competitive system.  This saves enormous amounts of time when actually cleaning blinds.  Some older 2" steel blinds can weigh several pounds, and are very difficult to open and close unless a support rack is purchased.  Why bother?  Clean the blind closed in a Zenith blind cleaning system.

Question:  "How does CROSSFIRE allow you to clean a blind in a closed position?"

Answer:  High frequency ultrasonics have the capability to produce cleaning action that is so precision that it can actually be produced between blind slats.  In fact, the 80kHz ultrasonic system included in CROSSFIRE can clean holes the size of a HUMAN HAIR!!!  As a result, it is rather easy for our systems to clean between stacked blind slats when a blind is closed.  The cleaning action is also VERY evenly distributed, leading to a very even cleaning result.   Competitive systems can not offer this feature for 1 very good reason:  Zenith has 2 patents on the CROSSFIRE system.

Question:  "How much ultrasonic power is included in Zenith blind cleaning systems?"

Answer:  This depends on the model selected.  The COMET includes 3600 watts of CROSSFIRE Multiple Frequency Ultrasonics in our 76" model, while the BASIC includes 1600 watts of power.  When comparing systems, always compare the wattage.  This is the amount of power that will be available for cleaning purposes.  Larger blind cleaning systems include even more power.

Beware of competitors which do not advertise the ultrasonic power in their cleaning systems.  It is VERY difficult for the average person to determine the ultrasonic power of a system once purchased.

Question:  "Why do Zenith ultrasonic blind cleaners cost  THOUSANDS less than other brands?"

Answer:  If you have shopped around for a blind cleaner, and have not yet received a Zenith pricelist, you are in for a BIG surprize!!  Zenith systems cost THOUSANDS LESS than competitive brands.  This is possible because Zenith is actually the manufacturer of the system rather than being an assembler of components purchased from several locations.  Most sellers of blind cleaners purchase tanks, ultrasonic components, and other items, then assemble the parts to make the complete blind cleaning system.  Zenith is perhaps the only seller of blind cleaning equipment which actually manufactures ALL of the components.  This provides several advantages.  Firstly, since there is no middleman, systems cost less and include more.  And, since we manufacture all of the parts, replacement parts are available in 24 hours.  We invite anyone to visit the Zenith manufacturing facility near New York City to view our manufacturing operation, and obtain an education on the ultrasonic cleaning process.

Zenith can even provide you with just the ultrasonic components should you wish to manufacture your own blind cleaning system.

Question:  "Why do Zenith ultrasonic cleaners all include a fluid heating system?

When you wash dishes, do you use heated water, or cold water?  Hot water dissolves the dirt and grime much faster, while also making the cleaning fluid more active, yielding much faster and more thorough cleaning results.

Question:  "What else can I clean in a Zenith blind cleaner?"

Answer:  Virtually any window covering that can be submerged into a liquid without damage can typically be ultrasonically cleaned.  This includes fabric and plastic vertical blinds, duettes, honeycombs, woven woods, and others.  If you intend to clean larger object for fire restoration work, our COMET blind cleaner includes removable ultrasonic components which will allow you to remove the ultrasonic packs from the cleaning tank and place them into a larger tank to clean objects which can not fit into the blind cleaning tank.  Other common items which can be ultrasonically cleaned include light diffusion panels, air conditioning louvers, and others.  The ultrasonic system used in our line of blind cleaning equipment is the same as that used on our industrial ultrasonic cleaners.  Therefore, virtually anything that can be submerged can be ultrasonically cleaned.

Question:  "Does Zenith include marketing advice with its blind cleaners?

Answer:  Yes, we do.  Zenith provides several publications which are directly related to marketing service oriented businesses.  On top of that, our System Guide includes advice which has been gathered after over 28 years of experience with blind cleaning.  Advice about who to approach, what businesses to approach, how to sell once you get through the door, pricing your services, how to market, and other important information is included.  With the information that Zenith Ultrasonics provides, one can easily start a new  mini blind cleaning business without any prior experience.

Question:  "How can I tell if a blind cleaning service will be successful in my area?"

Answer:  Individual success will largely be determined by the number of people that are within your marketing area, or area where you are willing to travel to.  If you are in a highly rural area, where the next house is 2 miles away, do not consider blind cleaning.  A good guideline for the number of people required to support a blind cleaning business would be approximately 60,000 people.  This is based on studies which were originally performed independently back in 1976.  Not much work will be required to pay for the equipment.  Most blind cleaning firms charge an average of $10.00 per blind.  Each blind will cost you only pennies to clean.  As a result, a house with only 10 blinds cleaned once a week will produce enough revenue to pay for the blind cleaning equipment.  Anything more than that is pure profit.

Question:  "Are Zenith blind cleaning systems portable?"

Answer:  This depends on the size of the equipment purchase.  Our 76 inch systems have been designed to be portable, and will allow for on-site blind cleaning operations, where the equipment is left at the customer's facility for the duration of the contract.  This is even more profitable since you use the customer's electricity, water, and other utilities to do your job. 

Question:  "Can ultrasonic blind cleaning systems damage blinds?"

Answer:  If the blinds are very old, and the paint has been "oxidized" by the sun, damage is possible if you do not inspect and test the blinds prior to cleaning.  Zenith provides you with a method that allows you to test whether or not a venetian blind, or other window covering, is subject to damage. 

Question:  "What sets Zenith blind cleaning systems apart from competitive blind cleaners?"

Answer:  The Zenith design has been based upon over 28 years of experience manufacturing such cleaning systems.  We have been manufacturing blind cleaners longer than anyone, and have designed these systems to include features and equipment not available on any other system.  Our patented CROSSFIRE Multiple Frequency Ultrasonic System allows the blind to be cleaned in a closed position.  Our COMET systems include BOTH spray AND submersion rinse methods, as well as a COMPLETE DRYING SYSTEM at no additional cost.  Our generators, and entire system, is manufactured using only 316L stainless steel, no painted objects are used in our tanks, framework, generators, or any other critical component.  Systems include more ultrasonic power as well.  And, best of all, ZENITH WILL NOT BE UNDERSOLD, and guarantees that we can beat the prices of any competitive blind cleaning system.  We truly hope that you compare our systems with others.

Question:  "Can Zenith blind cleaning systems be paid for with monthly payments?"

Answer:  Yes, Zenith does provide several leasing options, information that is included with our mailed catalog.  Your interest rate will depend on your credit rating.  A typical 76 inch COMET can be leased for under $400.00 per month.  At the end of the lease, the system is purchased for $1.00.  For more information, contact Zenith Ultrasonics.

Question:  "Why do Zenith COMET blind cleaners include 2 rinse methods?"

Answer:  To provide better cleaning results whenever possible.  Most competitive blind cleaners include only a tank filled with water into which the blind is dipped to rinse.  Unfortunately, each time a blind is transferred to the rinse tank, detergent is also moved into the tank.  After a few blinds, the rinsewater is completely contaminated with detergent, which leads to spots on the blinds when they dry, no matter what "rinse additive" you add.  You will need to change the water in the rinse tanks several times a day, a procedure which wastes time.  The BASIC blind cleaner will require these fluid changes, since this design does not include the fresh water rinse method unless added as an option. 

Zenith COMET systems include a fresh water rinse that uses fresh water to spray rinse the blinds.  This eliminates detergent spotting and eliminates the need to replace rinse water.  If a fresh water supply is not available, the standard submersion rinse method may be used.

Question:  "What if something breaks on the Zenith blind cleaning system?"

Answer:  You will never have to wait very long for parts, and parts are reasonably priced.  This is possible since Zenith is the actual manufacturer of the equipment, and keeps all parts in stock for immediate delivery.  And, our parts are realistically priced.  We have heard of switches costing $10.00 on a Zenith system being priced at over $75.00 on competitive systems.  When comparing systems, be sure to also compare the prices of replacement parts.  Our ultrasonic generators also power fewer ultrasonic transducers than any other system.  If one of our ultrasonic generators fails, you will lose only 4" of activity in your cleaning tank, allowing you to continue operations with no downtime.  This will become very important if you are in the middle of a large contract, and a component fails.  All components can be repaired by our customers using standard hand tools.

Question:  "Does Zenith provide training on how to repair blinds as well as clean them?"

Answer:  Yes, sources are provided which can provide parts and other materials for the repair of blinds.  In many cases, customers wishing to clean a number of blinds has a few which require repair.  This is especially true for schools and other similar institutions.

Question:  "How can I get more information on Zenith ultrasonic blind cleaners?"

Answer:  The catalog which is mailed to our potential customers includes an even larger question and answer section, pricing, options, and other information which was not included in this web site.  If you are interested in how ultrasonics actually work, visit our ABOUT ULTRASONICS page located on our industrial web site.  To receive our mailed catalog, click HERE to write a letter to Zenith where you can request information on our line of blind cleaners.

We hope that you have found this question and answer section informative, and look forward to hearing from you in the future.
