Karcher Professional Vacuum Cleaner Review

This Karcher NT 40/1 Tact TE M professional M Class vacuum is a thoroughly good machine that does three jobs for me well, first, it’s a really good vacuum for cleaning in general.

From construction dust that includes sand, sawdust, small masonry fragments missed by the broom to fine dust from flat surfaces, second it is a really capable dust extraction unit.

I connect the Karcher professional vacuum to various power tools from circular saws to electric planers the hose is nice and long and the machine itself is stable and on good castors so it moves freely as you work.

The third use is its wet vacuuming function this is particularly useful for plumbing jobs and site spillages, and it is simple to remove the dust bag to ready it for water etc.

The machine is M class and this is something we have to have to comply with building site regulations. The controllability of the vacuum is done by either selecting automatic or dialling the variable speed control and adjusting for different diameter hoses or attachments.

This vacuum its robustness and uses justifies the purchase price, it is a one-stop solution for construction professionals and cleaning contractors alike.

One final mention is the useful elasticated toggles that enable the hose to be stowed away around the top of the unit and then the metal tubes with the floor tool is located neatly over the rear wheels. Looking forward to spotless workspaces!

Thanks to the new fully automated filter cleaning system, our 40/1 Tact Te M wet and dry vacuum cleaner sucks up quantities of fine dust never before achieved whilst simultaneously guaranteeing filtration efficiency of 99.9%.

The device uses sensor-controlled electronics to provide optimum filter cleaning at all times and therefore maintain consistently high suction power.

Together with the large, robust 40-litre container with metal castors the device can not only handle very large quantities of hazardous fine dusts in dust class M, but also coarse dirt and liquids.

The NT 40/1 Tact Te M features a power outlet with auto-start feature as well as a full antistatic system including conductive accessories. It is therefore ideal for direct suction on power tools which produce large quantities of fine dust.

Dust that has already been deposited on the floor or on machines is safely removed using the newly developed accessory kit comprising a 4 m suction hose, stainless steel tubes and a wide floor nozzle. All accessories are stored securely on the device thanks to clever storage solutions.
