Hoover S3765-040 WindTunnel Bagless Canister Vacuum Cleaner Rating



Avg. consumer rating = 69/100 

The Hoover S3765-040 uses Hoover’'s patented WindTunnel technology.   Hoover does not go into great detail about how the WindTunnel technology works other than to say their engineers went to great lengths to develop a system that lifts and traps dirt very efficiently without any scattering. Reviews and ratings on this vacuum seem to vary widely, from good on Walmart to below average on Amazon.

What are consumers reporting?

- HEPA filter
- Good suction
- Telescopic wand
- Quiet

- Difficult to change the filter
- Short power cord
- Dirt canister too small – lots of emptying

The Hoover S3765-040 is a bagless vacuum cleaner which means that it collects the dirt/dust/hair in a canister that can be emptied and put back in  - it doesn’t need to be replaced.  This approach is usually considered good as it can save money over the life of the vacuum cleaner (no need to buy bag after bag).  It also eliminates the need to find the “proper” bag for your specific vacuum cleaner – this can sometimes be a trial as there are many different bags for many different brands and models of vacuum cleaner.  However it should be noted that it is sometimes a messy affair to empty the dust containers of bagless machines.

The S3765-040 is what is known as a canister vacuum cleaner.  Hoover makes both upright and canister models (not to mention a host of other specialized vacuums).   Historically canister vacuums have been better for hard surfaces and tend to be quieter – although they tend to be slightly more expensive.  The upright models have tended to be better at cleaning carpets.  However, recently the distinction between the two types of vacuum cleaners has become more blurred as the vacuums attempt to bridge the gap between each other’s strengths and weaknesses.

The Hoover WindTunnel Bagless also uses a HEPA filter.  What is a HEPA filter?  Well this item shows up in many discussions of vacuum cleaners and you have probably already read about these filters many a time.  HEPA stands for High Efficiency Particulate Air and is a filter that removes 99.97% of all airborne particulates of 0.3 microns or larger that pass through it.  There are actually higher grade filters such as ULPA which stands for Ultra-Low Penetration Air and is a filter that removes 99.99% of particles 0.12 microns or larger.  Although I have not run into any domestic vacuum cleaners using this level of filtration.  When considering a HEPA vacuum cleaner it is important that the unit passes ALL intake air through the HEPA filter prior to exhausting it – otherwise particulate matter is bypassing the filter and being introduced back into the surrounding environment.  HEPA filtration is particularly popular with allergy sufferers.
According to Hoover the vacuum cleaner includes the following attachments:
- six foot hose
- telescopic wands
- deluxe floor brush
- crevice tool
- powered hand tool
- filter cleaning brush
- dusting brush
- furniture nozzle

Other features include a reasonably powerful 12 amp motor and a headlight for illuminating areas that are dark or dim.   It also has a 25 foot power cord (that we feel is a little short) and is touted as Ultra-Quiet by Hoover (consumers seem to feel this is indeed the case).  It also has foot pedal cord rewind and uses Hoover's patented Windtunnel technology which, according to Hoover engineers, is a system that lifts and traps dirt very efficiently (using three distinct air channels) without any scattering. The canister itself weighs about 13 lbs but the vacuum in its entirety (with hose, nozzle, etc) weighs significantly more.


Pricing for the Hoover S3765-040 range greatly from as low as 165 USD to as high as 240 USD.  The vacuum comes with a one year warranty.
