why is the suction lost

Depending on how long you have been using the machine the tube could be stopped up with dead skin cells, but I know I have read a lot of reviews where people had this problem sometimes within a 30 day period. If this is the case I encourage you to contact the company ASAP because I know some people were complaining that they were very upset because they would not make good on the product. Good luck.

Be sure to replace the filter after you use the Nu brilliance 3 or 4 times. I also wipe out the inside of the head with a damp q-tip.

Various posts stated that it was due to a missing rubber seal however! Mine was in place just like the day I purchased. My father who's an engineer said they use cheap parts that once heated a few too many times (via using the machine), they lose power and strength. There was suction but it went from functional to barely there at all In a matter of days. Do not waste your money!!

Sorry... 'don't know why your unit lost suction cause mine still works fine. Per all the other previous feedback left about this product concerning suction issues, perhaps it has to do with the little rubber band on the hand unit. I would check that first. Good luck!

Hi Jan. I would assume that, like every vacuum cleaner, something could be stuck (may be in the hose) preventing the water to be sucked up.

There might be an air block in your plumbing system.Consult a plumber a get it fixed to get good suction.

I am assuming when you say it is loosing power you mean it is loosing its suction. I have not had that issue and the vacuum bag needs changing only when full. That depends upon the type of dirt or dust yiou are picking up and its quantity.Look in the manual for the description of ther small bag indicator on the vacuum.

There is not enough air flow across the filter. If it can not go through the filter it creates a higher than normal pressure on the inside of the filter. This higher pressure is greater than the latch holding force and pops off. Our vacuum did this after washing the filters. There was still to much moisture on the elements stopping the air from passing through. I blew it out with my air compressor and it fixed the problem.

I have to ask, what are you doing with it currently where it doesn't have suction power? what do you have hooked up to it?

I'd love to be able to help u but I haven't used it yet. I would guess it maybe vacuum holding it on. Not to b funny but have u looked in the owners manual? It may have some helpful hints.

The suction is not as strong. For that reason I could not give it five stars.

I've had mine attached to my windshield for two months now; taking my phone in and out of it frequently. I've never had a problem with it losing suction.

If there is suction loss, it is minimal. I'm impresses with the way it retains 98% of the debris in the Dust Deputy.

If you have the "Automatic" button selected then that would happen. Otherwise press the "Auto" button again to put it in manual and then select the Plus/Minus suction controls to the setting you desire. Mine however only changes the suction power when I use the hose, when in "Auto", but never while using the brush bar. Really doesn't sound like you have a problem.

I haven't had any problem with mine losing suction. It has been on my dash since October and has not come loose. Sorry..

No, there is NO suction at all with this thing. It just kind of sits there like a rock. AHHHHHH LIKE A ROCK!!

The vaccuum really sucks all the air out. Squishing it won't do the full purpose

Mine fell a few times also. Make sure both surface and suction cup are super clean and dry. If that still doesn't work - maybe you're overloading it? I found that was my problem. It doesn't hold as much weight as I'd like.

Theresa, I'm going to assume that you mean that there is too little suction to operate the unit? A testing device comes with the cleaner. You insert it into the end of your hose (where the cleaner would connect) and it measures the amount of suction available to run the vacuum. Mine runs (slowly) and the gauge shows that there is barely enough vacuum to operate it. Although it does run slowly, it does cover the whole pool and keeps it spotless.If you have even less vacuum available probably none of the vacuum-side cleaners will work very well. There has to be water movement inside of the cleaner to move the internal components and that requires a minimum of vacuum. You may have a leakage problem?

I've just grasped it firmly right next to the joins and pulled gently but firmly. I didn't pull hard but did do light tugging. I also will gently twist it while pulling it apart as that helps break any suction that might be holding it tight.
