Heavy Duty Central Vacuum System Attachment Kit CV78PRO CV78PRO-PT Universal (corded) Connect Hose
This model of the CV78PRO series is the Pigtail or Universal Connect hose style, sub model -PT. Our Universal Connect Professional attachment group includes a new lightweight crush-proof hose with a regular connection cuff that includes a 7 foot cord attachment (called a "Pig-Tail") built into the hose cuff that plugs into a standard electrical outlet somewhere nearby the CV inlet to provide electricity to the premium power brush.

This type of connection fits most wall valves on the market today where power for electric attachments is not supplied directly by the CV wall plate. Our universal Pigtail hose is designed to work with all standard wall plates, even some of those that were installed years ago and those that may not have originally included a powered attachment group. If you are unsure which hose and attachment kit you need for your current system, or which type you should install for a new system then please read our article linked below titled CENTRAL VACUUM HOSES AND INLETS EXPLAINED Premium Central 
Vacuum Attachment Group CV78PRO

Standard connection is generally the preferred inlet valve type for retrofitting installations (new install, existing home). This type of installation does not require that you also run 120V wiring to each valve, only a low-voltage signal wire that is used in all CVS installations. To use the Central Vacuum System with standard connection valve and pigtail hose you need only plug in your hose to the wall.

When you need to supply electricity to the powered brush for cleaning carpets just plug in the cord that is connected to the hose wall cuff to an electrical outlet somewhere nearby. The pigtail cord on the hose is 7 feet long, and can easily stretch across a hallway if needed. The CV78PRO series is also available in model CV78PRO-DC (see link at bottom of this page) with a direct connection wall end. If you are not sure which style you need, just give us a call or send an email.

The Heavy Duty Commercial Powered Brush
When vacuuming with a powered brush one premise holds true: Faster is Better. Unlike its domestic competitors the European manufactured Lindhaus commercial power brush uses a geared belt drive and independent brush motor to drive their brush at over 5,000 RPM.

Heavy Duty Central Vacuum System Attachment Kit CV78PRO That is nearly twice as fast as most power brushes. The unique brush roll is driven at this speed consistently during cleaning, allowing our nozzle to surpass all conventional flat belt drive products. The Lindhaus PB14 PRO is a true Commercial Powered Brush with a widepath nozzle, a full width of 380mm and a cleaning path of 14 inches.

The Lindhaus PB14-PRO nozzle is made for heavy duty and critical cleaning applications. The PB14-PRO is not offered by those distributors whom offer only systems for cleaning residential or light duty applications due to it's over engineering and higher price than most standard power nozzles. The standard duty Lindhaus PB power brushes are great nozzles for residential applications, but differ a great deal in design from the PB14-PRO. The PB14-PRO is a derivative of an industrial vacuum, the Lindhaus RX series, and includes many advanced features for high usage applications.

Heavy Duty Central Vacuum System Attachment Kit CV78PRO The Lindhaus PB-PRO power nozzle uses the geared drive system for unsurpassed performance. Geared belt drive systems offer unsurpassed cleaning performance for carpeted floors. If geared belt drive is so superior to flat belts, why does not every vacuum use a geared belt? This is a great question, and the answer is that the ability to drive a brush at 5,000 RPM is a complicated and costly procedure.

First, you must balance the rotating brush to such a high degree that special equipment is required to do so. If improperly balanced or unbalanced quality brush were used it would become damaged by the additional stress placed upon it rotating at such a high speed. Other parts must also be able to work within these tolerances, such as the bristles, bearings, pulleys and belt.

Heavy Duty Central Vacuum System Attachment Kit CV78PRO Most all domestic vacuum nozzles use a single flat or round belt. This low-tech approach is cheap to manufacture, and adds more consumables to the vacuum nozzle and requires service. When using a conventional vacuum nozzle, the moment the brush roller touches the flooring slippage occurs. After 10 to 15 hours of use the heat and wear on the belt has weakened it enough that belt slippage becomes noticeable. A weak belt can result in a loss of up to 50% of the rotational speed.

Remember again faster is better. The geared belt drive also provides an additional benefit that is not found in most flat belt nozzles; excellent edge cleaning on both side of the brush. Thanks to the narrow width of the geared belt the bristles at the end of the brush are closer to the edge than regular power nozzles.

Heavy Duty Central Vacuum System Attachment Kit CV78PRO The geared belt of the PB-PRO (shown above colored red) is synthetic, made of neoprene and is fiberglass reinforced. Rubber is not needed because the belt does not stretch into place or require tension to spin the roller. The PB-PRO belt does not stretch out and does not require replacement like standard flat belts and is warranted for 3 years, and will last much, much longer. The bearings are sealed true commercial precision bearings, not the usual throw away bearings as used in most other domestic vacuums.

The bearings are matched by the manufacturer for the speed and load of the application. The bearing holders are also unique and are made from cast aluminum. Most power nozzles use plastic end caps to hold the brush which mount into a plastic base. The problem is that most times the end of the roller will become tangled in threads, hair and carpet fibers which become heated by friction then melt the end of the roller and the base of the nozzle.

Heavy Duty Central Vacuum System Attachment Kit CV78PRO The PB-PRO end caps are made from cast aluminum and use o-rings to seal dirt, dust and threads away from the bearings which prevent damage to the brush roll and base structure. To reduce noise and vibration large rubber caps cover the brush bearings so the transfer of power from motor to brush is smooth and quiet.

The bristles on the brush roller of the PB-PRO are also commercial quality. The bristles are rated at 600 hours of use before failure. That's 6 - 10 times the life expectancy of domestic brushes. Considering that the brush roll is the only wear item of the PB-PRO you can see the low cost of maintenance for the PB-PRO. Other quality Power Brush features include convergent bristles, which means two rows of brushes are always touching the floor at one time, pulling everything to the center. The funnel shaped, center mounted brush nozzle intake with a geared belt is also unique to the PB-PRO Nozzle.

Heavy Duty Central Vacuum System Attachment Kit CV78PRO The PB-PRO uses an electronic logic circuit that monitors the brush speed, constantly checking thousands of times per second for a possible overload. On most domestic vacuums this is not required, the brush simply does not spin fast enough, nor is there any direct drive on a flat belt system. This same logic circuit also alerts you via LED lights on the power nozzle when the brush is set too low. No more guessing if the vacuum is adjusted correctly, no more wondering if it is time to replace the belt.

How many times have you inadvertently vacuumed up a throw rug or article of clothing? In a normal vacuum, you at least break a belt, and possibly burn out the motor. With the logic circuit in the PB-PRO, the brush stops and signals the user with a red light. This allows you to unplug the machine and remove the object from the nozzle before damage can be done. Plugging the power brush back in automatically resets the circuit and you're ready to clean again.

Heavy Duty Central Vacuum System Attachment Kit CV78PRO The nozzle connector of the PB-PRO is a double swivel that articulates both up and down, and side to side for complete control. The button locking connector fits a standard 32mm button lock wand for a positive locking connection and uses a release pedal to recline the nozzle into a cleaning position. The front and belt side of the nozzle are wrapped with a non-marring furniture guard to prevent damaging walls and baseboards and the boltless edge cleaning side features baseboard rollers. Only found on the PB-PRO the baseboard rollers are made from nylon and are vertically mounted in a metal housing. When cleaning against a wall or cabinet the rollers help the nozzle to glide down the wall providing excellent edge cleaning without snagging or marring.

Heavy Duty Central Vacuum System Attachment Kit CV78PRO All four wheels of the PB-PRO are covered with a soft vinyl tire which protects the floor and provides excellent tracking on floors of all types. All four wheels are mounted on metal axels that provide for extended usage and wear resistance over the more common plastic wheel mounts. The PB-PRO cleaning shoe (opening for the brush) was also redesigned from the domestic nozzles and is covered with stainless steel plates and carpet protectors. The stainless steel plates prevent damage to the bottom of the nozzle that is common with high or rough usage. Standard power brushes use plastic bottom plates that can become damaged when banged into heavy furniture or dragged over door thresholds.

Heavy Duty Central Vacuum System Attachment Kit CV78PRO Another feature exclusive to the PB-PRO is the side entry brush roller. In other power brushes the complete nozzle must be disassembled to remove the brush roller from the housing for service or replacement. The PB-PRO's unique side entry roller housing features a removable door that slides off the nozzle and allows you to remove the roller from the nozzle without the use of any tools and without taking apart the nozzle base. This exclusive feature allows cleaning crews to service the PB-PRO in the field, on the job without having to return to a service center for cleaning or maintenance.

Heavy Duty Central Vacuum System Attachment Kit CV78PRO Yet another feature exclusive to the PB-PRO is the filter door with removable and washable foam filter. The filter is mounted on the back of the nozzle housing and protects the brush motor by filtering the air that is pulled into the nozzle for cooling.

Internal features of the PB-PRO include a cushioned motor mount for less noise and vibration, solid state circuit board, steel wear plates in the pivoting nozzle connector and a micro switch that automatically shuts down the power brush when the handle is locked in the upright position. Despite it's impressive feature set using the PB-PRO is simple for anyone.

You need only connect the PB-PRO to the cleaning wand and plug it in. The carpet height adjustment is designed to clean 90% of carpet types set in the middle of its range and will require no further adjustment. Heavy Duty Central Vacuum System Attachment Kit CV78PRO The brush indicators will monitor the nozzle while in use with a green light and alert you to any problems with a red light. The PB-PRO is designed for high usage and built to take the rough use of service work. Perfectly suited to cleaning large offices or commercial buildings, restaurants and other areas with large carpeted floor spaces. The PB-PRO is equally well suited to cleaning the average home and will perform reliably for many years.
