Today I used it for the first time and collected the amount of ash from a day from the energy fireplace (a considerable amount of ash and charcoal). Very satisfactory suction, it didn't get stuck anywhere. So far, very satisfied. Karcher guarantee…

Very powerful vacuum, easy to empty when full and very good filter, no pollutants escape into the room.

very good vacuum cleaner pulls the ash from the fireplace quickly, powerfully and quietly compared to another one I had that sounded like an f 16. be careful read the instructions very well I have cleaned the fireplace four times and I haven't shaken the filter yet and the vacuum pulls like nothing is wrong.

The vacuum cleaner has a lot of power and is of good quality. I read the negative comments, but they all have to do with maintenance, like all tools. If you use it with a clogged filter, it will burn out. Its weight is proportional to the quality of the materials. Simply remove and shake the filter after each use and it's good to go. If there is no outdoor space for use, it may be a problem due to dust. It's worth it though.

For the trash. Within 3 years, the motor burned out twice. It brings dust into the space when you clean. Stay away

Powerful vacuum cleaner, reliable product, top-notch KARHERR, especially in cleaning systems. However, when you use it continuously (we're talking about daily use for over 2 years), it has serious issues. The main issue is the cleaning process of the filters. It is very tiring and after 2-3 uses, it needs cleaning. The flexible filter is difficult to clean and takes time. Also, the placement of the metal canister inside the body of the vacuum cleaner is very problematic. If you don't pay attention, it easily gets blocked. Issues can arise for no reason because of this thing. Also, the replacement parts are very expensive compared to the initial price. In other words, it is very good but not value for money

What you pay, you get.. I use it in a pellet fireplace, for four months now... The main advantage is that it doesn't leave dust during use, as the brooms I used before caused a big dust problem when using them. It is the only broom that has self-cleaning of its filter, (pay attention to the instructions for use), as well as the fact that the filter can be washed and reused. Excellent quality materials... Very good suction if you do the proper self-cleaning after use.. I don't rate it with excellent because I have been using it for four months now..

It is a bit heavy and difficult to clean the filter, it does not leave small particles in the environment. Plus, it has a long cable.

Simply amazing, as long as we know how to use it... It is good to read the instructions as they clearly explain how to use it correctly, since it is one of the few that automatically cleans the filter.

It is not what I expected, it sucks small amounts of ash, however after a few uses it gets clogged and doesn't suck anything. I wonder why it has such a large bin since the amount you can collect is small. In order to do the job, you have to constantly wash the filter.

Very powerful vacuum cleaner, collects ashes perfectly from a pellet stove and doesn't leave any odors or dust in the area.

Very powerful vacuum cleaner. It works perfectly for 1 year now on pellet fireplace. Easy cleaning. Absolutely satisfied.

Good absorption without dust passing into the room. Moderate noise. Very satisfied for the price of 85 €. The expensive filter is a disadvantage.

I have a fireplace and I have been using it since the beginning of winter for about four months. With the slightest bit of debris, it gets clogged and needs to be opened and cleaned. I got tired and in the end I gave up on it and clean it in the traditional way

Excellent vacuum cleaner, very powerful. When the suction power decreases, simply shake the filter inside your fireplace, hitting it lightly somewhere. No need for anything else.

The bin seals very well without letting any ash pass into your space.
Generally, the vacuum cleaner does not emit anything while sucking up ash, unlike other lower quality ones.
It has a high absorption power, which, however, decreases significantly after a few cleanings.
But with the washing of the filter, the absorption power returns to satisfactory levels.
The filter cleaning mechanism is convenient, but almost useless, since when the filter collects a lot of ash, the situation can only be corrected by washing.
Overall, I am completely satisfied so far.

I clean the pellet stove. I have been using it for 1-2 months now. It is not so powerful, but it works well for ash. The filter needs to be cleaned relatively often, otherwise you can feel that it doesn't pull as much. Very good quality.

On 22-12-20, I want to clarify that it has a button on top that I probably wasn't using correctly. While it is working, you press a button on top and it rotates the air onto the filter and cleans it. So, almost every 10-12 cleanings of the stove, I clean the filter now.

I highly recommend it.

UPDATE
I have been using it for 2 years now during the winter for cleaning the pellet stove. It still works great even now. KARCHER quality.

Sturdy construction with no ash smells, also useful is the button for cleaning the filter. It doesn't clog and sucks up even small pieces of charcoal without any problem

Very good and user-friendly. Karcher could also provide an additional "nozzle" so that it can be used as a regular emergency vacuum cleaner.

!!!The second time I collected the ash, it got clogged, no matter how much I cleaned or did, it never drew ash again!!!! Pure scam!! Plus, the latch broke where it fastens and it doesn't fasten anymore!!

The vacuum cleaner may be expensive compared to others, but it does not require regular cleaning, does not clog, and the 600 watts are too much for the ash I collect. It is made of solid materials and does not have fake plastics
