Sanitaire S645A Vacuum Cleaner Introduction

If you are looking for a powerful and very durable upright vacuum cleaner at an economical price, the Sanitaire S645A Professional upright may be the one for you. For many years Sanitaire has had an excellent track record of consistently producing commercial quality products which perform well and seem to last forever. The Sanitaire S645A Professional continues their tradition of excellence with its outstanding cleaning effectiveness, incorporating an efficient motor with extra-large suction producing fan and very durable revolving brush roll.

Heavy Duty Construction

The Sanitaire S645A is a commercial quality upright which is designed for heavy duty home cleaning. Its base plate and complete handle are made from durable chrome plated steel. Even the handle release pedal and latching mechanism are made of hardened steel for extra long life. Eureka is an industry leader, having successfully used Lexan for manufacturing their upright bases, fans, and other parts requiring high impact resistance since the mid 1960s. Lexan is General Electric's registered trademark for a particular type of polycarbonate resin. It is an extremely tough and strong synthetic plastic with the ability to maintain its shape and size even under great stresses over a wide range of temperatures. This makes it ideal for the main base of the Sanitaire S645A. It is light weight but extremely tough, being able to flex and handle high impacts without breaking.

Efficient 7.0 Amp Motor

Large amounts of air flow and rigorous carpet agitation powered by its 7.0 amp. (840 watts) high performance motor combine in the Sanitaire S645A Professional upright to deep-clean all types of carpeted floors. Featuring lifetime lubricated ball bearings and well constructed motor parts it will perform dependably for many years. When it comes to cleaning carpeted floors, this upright will out perform most uprights, even those with higher amperage ratings.

Efficient and Durable Suction Fan

The sturdy, well designed suction fan in the Sanitaire S645A is one of the most efficient in the industry. The fan's extra large diameter and tall blades are designed to handle large volumes of air efficiently. This special fan, combined with the extra large air passages and extra large paper bag, produces an extremely high amount of air flow through the system for very effective cleaning. Being made with Lexan, it is extremely tough with the ability to maintain its shape and size even under great stresses over a wide range of temperatures. Its ability to flex with impact enables its blades to take direct hits from large debris with minimal risk of breaking.

Heavy Duty Brush Roll

The chromed steel brush roll, named the "Vibra Groomer II", has successfully been used for years. The brush strips are replaceable, reducing the cost of replacing the complete brush roll. The brush roll revolves on two sealed precision ball bearings which are protected by metal end caps for longer maintenance free operation. Except for the brush strips, the complete brush roll assembly is metal and should last the entire life of this heavy duty vacuum cleaner. For reduced vibration and extended life, its metal end caps are mounted in rubber when the roll is inserted into the Lexan base.

Center Mounted, Funnel Shaped Air Intake

The center mounted air intake behind the brush roll flares out to the edges of the cleaning nozzle as it approaches the brush roll. This wide funnel shaped opening causes the air flow to be distributed quite evenly across the entire cleaning width for more efficient and uniform cleaning. This also creates a flat dirt collection area immediately behind the brush roll so dirt and grit are gathered and whisk away by the air flow before they can bounce back out of the nozzle. This substantially reduces the scatter effect which many uprights experience when picking up grit and small stones.

Triple Filtered Bag System

The Sanitaire S645A comes equipped with a filtered outer bag which is designed for use with extra large paper bags for greatly increased filtering efficiency. You can choose from two types of paper bags to use in the Sanitaire S645A, depending on your filtration needs. Their economical standard paper bag is designed for those who do not need the micron capabilities of Eureka's Premium paper bags. Their Premium paper bags have a filtration efficiency of 99.9% down to 1 micron in size, making them capable of filtering out over 99% of pollens, 98% of selected bacteria and 95% of all yeast and fungi that would normally be put back into your home's air after vacuuming with standard dust bags. Premium bags have the ability to filter out 10 times more of sub-micron size particles than ordinary vacuum cleaner bags. This filtration is accomplished with minimal loss of air flow.

Far Reaching 30' Power Cord

The extra-long 30' power cord enables you to clean large areas without breaking your pace to change to a different electrical outlet. Its kinkless vinyl cover and the quick release top cord hook enable you to wrap in on the handle and remove it again with greater ease.

Extra Wide Heavy Duty Wheels

The Sanitaire S645A has extra wide wheels which will roll easily over your carpeted floors while enabling this upright to be easily pivoted for excellent maneuverability around your furniture. Being made with tough vinyl using a reinforcing ribs design, they will perform without breaking for many years to come. All wheels are mounted on steel axles for reduced friction and extended life. The extra wide rear wheel base adds to the stability of this commercial quality upright.

Convenient Height Adjustment

Easily adjust the Sanitaire S645A to match the exact height of your carpets with the front mounted six position height adjustment knob. This enables you to set it exactly as need for optimum cleaning and ease of use.

Outstanding Warranties

Sanitaire provides three years of peace of mind, knowing that you will not have the expense of a repair which is covered by their Three Year Limited Warranty. In addition to this, their new Five Year Limited Motor Warranty provides two additional years of peace of mind, knowing that you will not have the expense of a motor repair which is covered by this warranty. This also reflects their confidence in this machine's excellent quality.
