[Solved] Amica VM3043 Vacuum Cleaner: Loss of Suction Power After Few Uses - Filter Replacement Ineffective

Hello. I bought an Amica VM3043 vacuum cleaner, my friend also bought it at the same time. After the purchase, the vacuum cleaner vacuumed very well, had power, easily lifted the carpet. After a few uses, the vacuum cleaner has no power. Cleaned filters, blew everything out with compressed air, nothing. A friend had the same thing, the vacuum cleaner went to the service - they said that the filters needed to be replaced (although after a few vacuuming they were not bad), after replacing the same. Has anyone had the same problem? Everything checked several times and the vacuum cleaner has no power. There are many similar comments on the internet, I don't know if there is anything else I can do?

same after replacement.

So there is no thrust right away, or again after a few vacuumings?
Turn on the vacuum cleaner without a filter and evaluate the draft. If the draft without the filter is good, then the filter is clogged again and unless it is washable, it cannot be restored to newness by blowing it out.

I checked it, without the filter it's even worse

Well, if possible, run it without the dust container at all. Evaluate engine speed and work and wind. Maybe something in the container is clogged. After that, it will only find the engine. Although it is probably unlikely - maybe the turbine making the thrust is not tightened and slips on the rotor.

Checked again, without a filter, the vacuum cleaner does not pull at all. The container is pulled out, the engine is running, the speed control works, I put my hand on it very weakly, I feel that it is pulling. I can buy a new filter, only if after a few uses the filter would have to be replaced (PLN 50 to spend every 2 months is probably not an agreement, a vacuum cleaner costs PLN 200). Regards

Filter fault. These are the charms of bagless vacuum cleaners that I am not a fan of.
Clogged crevices. I do not know if you can soak this filter with water, but I once laboriously cleaned the slots under a stream of water in another vacuum cleaner. I dried it and the suction came back.

Wait a minute, if a vacuum cleaner without filters still has low suction power, then something is wrong with the turbine / motor. I assume we're blowing off the warranty, which is kind of fictitious anyway from what you're writing. Therefore, I would look inside and check, first of all, whether the turbine is permanently mounted on the motor axis and whether the seal between the turbine and the housing adheres well, whether the rubber / foam or whatever is there has not spilled. And that all housing seals are in contact with each other. I had a case years ago that Zelmer Wodnik lost the tightness between the tank and the cover and the effect was as above. Parameters such as vacuum pressure and air flow should also be distinguished.

On the epa12 filter there is a seal that connects the tightness of the container and the vacuum cleaner. Removing the filter causes air to be sucked in from the sides and therefore the suction is weaker. Let the author confirm or take a few photos of the filter from both sides..

That's exactly how it is.

I understood that you have two filters. Since a vacuum cleaner without a filter (without a frame) does not work, I suggest sacrificing one filter and punching a paper insert in it so that it does not resist the air. If it still won't pull, then the only thing left to check is the engine. Since the vacuum cleaner is under warranty, and the possibility of self-repair of the engine is small, I suggest not to disassemble the housing hastily.

This vacuum cleaner?

Yes, the vacuum cleaner. Out of curiosity, I downloaded the user manual, an excerpt from it is included below. An interesting fact: the manufacturer provides an interval for replacing the outlet filter (every 6 months) and only cleaning the inlet filter (very strange). According to the instructions, I rinsed the intake filter twice in warm water (previously only with compressed air). After drying it and putting it in the vacuum cleaner, it finally came back to life and pulls like crazy . The exhaust filter has been blown (it is like new). Unfortunately, the construction of the vacuum cleaner is very weak, because such an inlet filter will have to be cleaned every 2/3 of use, and replaced once in a while. The container gets clogged very quickly, after the second vacuuming you have to clean it. But for a vacuum cleaner for PLN 200, I do not require "miracles". Regards

Filter to replace, close.
