What is the suction power in mmHg?

you can suck the blood to the top of your skin or soft sucken. it can be set either way. it works very good and cleans your skin. i use at least one time a week but i like to use twice..love the way my skin feels.

You have to connect one of the hoses to the plug on the left with the filter, chose the appropriate size instrument for the area you are treating, set the power to the setting recommended on the instruction sheet. The suction happens when you place the instrument against your skin. I hope this answered your question

No, I have not noticed any reduction in suction power. I am very pleased with this product as well as the savings. Y

It has very powerful suction. The different stages of filtration refers to the pressure that the unit sucks. There are different heads for different levels of abrasion. I am happy with my purchase.

Bonnie - 1/3 hp. It will hold 28 to 30in Hg in smaller sealed systems, such as automotive AC. Note that vacuum in this unit is constant and increases up to about 30in Hg. The equivalent in PSIa (a = absolute) for 30in Hg is roughly 15 PSIa. Note also that you will require a vacuum gauge to monitor vacuum; not a pressure gauge. Hope that helps.

The Hoover GUV I purchased is a 10 amp model. It has all the power I need and have been very happy with this product. Hope this helps.

I don't know for sure but it does have a lot of suction. You might want to try contacting Bissell and asking them.

The amount of pressure used in the vacuum process is measured in inches of mercury and is between 18-22, or 609.5475468-745.0025572 millibars.

I live in Hawaii and my home is about 10 feet above sea level I could pull 28.0"- 28.5 +" hg. I ran the pump for one hour, 29.921" Hg is (absolute vacuum) so this pump is not that far off from absolute. Keep in mind atmospheric pressure and 'your' altitude affects vacuum pump performance

There is no rating as far as max hg of mercury or anything. But ive used to pull a vacuum on a few systems and havent had any problems with it. Been able to get to 500 microns

I personally would never buy another one. I returned same day I got it. Used it on very low pile carpet and was very hard to push across the carpet. As far as suction I am not sure because I wasn't going to have a vacuum I had to fight.

Does not require a power head.Suction is so much stronger than our previous unit.

The connection on the head has a bend where it swivels, so I swivel it to the side so my hose will lay parallel with the floor to vacuum under beds. This vacuum has a lot of suction power.

I use a Shop Vac to provide the suction. On both the inlet side and the suction side, I use a 1 1/2" x 1 1/2" rubber coupling with appropriate hose clamps. Works just fine.

B.Keller, did the battery upgrade increase the power of the suction or how long the batteries last?

Great Question :) As you see when you read the reviews enough power wont be a problem with this vacuum. It has an Amazon 107 CFM (even with the HEPA filter installed). It has more power than even most central vacuums. As a side note when you see a company giving its power rating in "HP" it usually means that they are hiding the power rating. HP ratings mean nothing and all standard ratings on vacuum cleaners should be done in CFM. Hope that helps :) Thanks Dustin GreatVacs (seller)

I have not noticed any difference in suction, but I'll pay closer attention next time I vacuum to see if there is! (I'm guessing it's a minimal difference, if any, if I haven't noticed it!)

Sorry I cannot provide an answer to that question. You might want to call a vaccum repair service with that question.
