wd6p purchase early 2019 ...
Expensive bags ...
6 months later, the button/switch breaks ...
The suction is and has been mediocre at best compared to older models ...
The wheels are fine, but the vacuum falls apart at the slightest touch ...
The foot has been changed 3 times until today ...
The power cord has been replaced ...
The end of the hose where the handle goes broke ...
The motor ran out of carbon brushes, replaced with the motor's code
and not the vacuum's, where the price was much higher ...

After 3 years of use in construction work for apartment renovation:

Positives:
1. It is used without a bag. Officially. The corresponding Nilfisk and other brands DO NOT work without one, it is stated in the manual. I bought one and returned it.
2. For any urgent liquid absorption, there is no need to change the filter. Very important. With most other vacuums, in a situation where you quickly need the vacuum, it simply doesn't do the job.
3. The filter is relatively easy to remove, it cleans well, not perfectly.
3a. Very important: the filter has a self-cleaning button. When it gets clogged, you block the hose and press the button, the airflow reverses and the air blows the filter backwards/towards the bin, and it unclogs in 2 seconds.
4. It has many very useful attachments, such as the flexible short hose for handheld tools (although it is quite thin and can get clogged) and the elastic adapter for handheld tools.
5. It is relatively quiet.
6. It sucks quite well if the filter is properly cleaned.
7. It has bases for all its accessories.
8. It has a socket for automatic vacuum start with the tool's start.
9. It has a flat base on the top, to place electrical and other tools, like a convenient table.
10. It has a long enough main hose, and there is also an extra long and thick one for debris, maybe it should come with that one.
11. An extension hose is also available.
12. It doesn't seem to generate static electricity.
13. It has a variable suction power, from very low to maximum, with smooth transitions. The power also works with the tool socket.
14. All the attachments come on and off very easily, even with the most stubborn tools. This is not at all a given. A Nilifisk of similar value was truly an ergonomic disaster. To change the nozzle to a tool connection nozzle, using a screwdriver was not enough, it required breaking the plastic... I returned it the same day.

Negatives:
1. In blowing, it does almost nothing. It probably has some kind of ECO mechanism like turbo, which only works in suction to increase performance, but doesn't work in blowing. Almost useless. A 50 euro Einhell blows 3 times better (but it's not good for anything else).
2. It is quite heavy.
3. The filter, although placed high, gets clogged very quickly in chiseling or wall sanding tasks. It's as if the dust goes straight there before going into the bin. Of course, there is always the quick filter cleaning button that I described in point 3a of the advantages. Maybe with a modification of the inlet chute or a stocking at the filter inlet, the situation would be better. There is always the option of using a cloth bag, which is cut at the bottom, folded, and held with clips, thus making it a single-use, multiple-use bag.
4. The filter doesn't come out unless you remove the rigid hoses/accessories from the back where they are stored. A small but noticeable ergonomic flaw.
5. The upper base of the accessories easily catches the hose at its lower part when working at heights. Noticeable in electrical chiseling.
6. The detachable head does not include the hose inlet. Meaning, it cannot be used without the bin, which was often useful with previous vacuums.

It would receive fewer stars, but for its price, it is the best in relation to the competition then and maybe even now.

I used it for quite some time as a second vacuum cleaner for the basement and occasionally at home. Where the vacuum cleaner proved its worth was in a complete renovation of a relatively large 120 square meter apartment where almost everything was done, drilling, repairs to walls, sanding of frames, and anything else one can imagine. The ability to directly operate the appropriate tool on it and literally absorb the dust is worth every penny. It starts and stops automatically. I always used it with a bag as a good friend suggested. The fabric bag collects the very fine dust from the construction work that penetrates everywhere and greatly increases the motor's lifespan. For those who need an electric vacuum cleaner for their apartment, there are much better options. However, for those who do DIY projects and need a multi-purpose vacuum cleaner for all dirty jobs, then it is one of the best choices.

I use it in construction to connect various machines and so far everything is okay and more than enough

Today I bought it....at first glance it seems very good for the job I want it for....but the blower makes a bit more noise than the vacuum cleaner sucks....but when I try it out properly, I will let you know....I'll be back!

Low absorption, especially if you don't use a bag the filter will clog in a few minutes. Airplane noise. It's not suitable for the house because it doesn't have a carpet brush. It's not flexible. Generally, it's only good for storage-garage. The blower function, for which I bought it, doesn't do anything, it blows like a hairdryer.
