Best Industrial Vacuum Cleaners: Comparing Bosch vs Starmix L 1425 for Renovation & Dust Cleanup

Hello.
A general renovation in the house is being prepared, starting with the replacement of all windows. I want to buy an industrial vacuum cleaner. The application includes gypsum dust, cement dust, shavings, small pebbles, etc. I have no idea at what price to look for it to be equipment for years for my own use but so that the service does not eat me. I was thinking about the blue Bosch for about PLN 750, but a friend praised the twice as expensive Starmix.
Does anyone have experience with the model STARMIX Industrial vacuum cleaner L 1425? Do you have any other suggestions?

About 4-5 years there I bought for one general renovation some Chinese with the designation BY781. I did not expect miracles, however, the vacuum cleaner surprised me incredibly. Withstood the entire renovation, from cleaning after minor demolition, through working with a plaster sander and a hand circular saw for wood, and at the very end it was used for thorough post-renovation cleaning and cleaning the fireplace. I took it later to the company because at home such a mare does not work. Currently, it is the beloved vacuum cleaner of our cleaner and is used, among others, for cleaning company cars. He also went to work for a client a couple of times. I was surprised by the work culture (it is quite quiet), the suction power, and now, in retrospect, durability.
Regarding Bosch, I have heard the opinion of finishing companies twice that as a vacuum cleaner for plaster dust, it is no different from the competition. The filter tapping system can be inserted between fairy tales. It helps for a while after turning the vacuum cleaner back on, but due to the size of the particles and the density of this dust, there is no effective method of filter regeneration. Only regular change of bags and cleaning of the filter with compressed air.
I also had the misfortune of using the Sparky vacuum cleaner. It was loud, weak, the bearings went to hell three times over the course of several years, and the plastic from which the body and accessories were made was exceptionally fragile.

I can't find your vacuum cleaner model (finds suction tubes). Do you remember how much it cost. At the beginning, I was also thinking about the market Graphite for PLN 450. I don't even have a chance to test it now because I know what time it is now. The price is 1/4 Starmix so I'm wondering if it's worth bothering with it?

I bought it for some pennies in Poland. I don't remember how much it cost but I think it was around $150. Graphite was bought by my friend who deals with renovations. As quickly as he bought, so quickly returned. The bearings failed after a few weeks.

I will follow the topic, because a general renovation is also coming soon and after the experience of one renovation, I want to be smarter and buy a vacuum cleaner that will reduce inhalation of dust.
Amateur renovation, for use with a plaster grinder, so necessarily with a shaker, easy to use and with generally available cheap consumables. The budget does not allow me to buy professional equipment with an automatic shaker, and I will use it more often for my home workshop than for repairs. I looked around a bit in the price range I have: up to PLN 700 - PLN 800 (I allow up to PLN 1000 if it is very advisable) and I found the following options:
Modeco MN-94-153
MAKITA VC2512L
Metabo ASA 25L
Nilfisk MULTI II 30T EU
Nilfisk Multi II 22 INOX
Bosch GAS 12-25 EN
Karcher NT 22/1
karcher WD5
DEDRA DED6603

Would anyone be kind enough to advise or suggest what to choose from the list above or maybe know something better in good money. I'm just looking for new hardware.

Take a look around how much the accessories/filters for the models you find cost. Because operating costs can be high. On the north.pl website you will find, in addition to consumables, available spare parts and their prices. Compare the suction power (vacuum) and air flow of each model. For dust or chip extraction, flow is important; high vacuum is useful when vacuuming large and heavy or wet dirt.

@marekwroc What model of vacuum cleaner did you finally decide on?
