Metabo’s new cordless vacuum cleaner

Metabo’s new cordless vacuum cleaner offers versatility, power and convenience.

A clean working environment is indispensable for health protection, and a powerful vacuum cleaner for professionals in the wood or building trade is, therefore, essential. With the new cordless vacuum cleaner from Metabo, tradesmen now have a unit that allows them to work without a cable getting in the way, and still not have to compromise on suction power.

“Thanks to a powerful brushless motor, you will not notice any difference to standard mains-powered vacuum cleaners,” declares Metabo product manager, Sebastian Koch. “The cordless ASR 36-18 BL 25 M SC is classified as dust class M and provides first-rate suction power. It holds back 99.9 per cent of the dust generated, which means that professionals who are exposed to the likes of quartz dust, for example, are ideally protected.”

A clean solution

The new machine can be operated with two 18V battery packs, or one 36V battery pack, and has three different levels to which the suction power can be regulated, depending on the application. Continues Koch: “For example, if the professional uses a cordless orbital sander that generates less dust, he can reduce the suction power accordingly, and increase the battery pack runtime in the process. In this way, he can work longer and make full use of the battery pack`s energy. A particularly large amount of fine dust is generated when sanding wood or plaster filler, for instance. The filter of the vacuum cleaner gets clogged with dust during longer applications. We also have a solution for this: the semi-automatic filter cleaning. The technology is already in use in mains-powered vacuum cleaners, now we have developed it further for cordless vacuum cleaners. The filter cleans itself automatically during breaks, whilst cleaning can also be started manually by operating a switch.”

Extraction with automatic start/stop

The “CordlessControl” system takes over the automatic start and stop of the vacuum cleaner. Thanks to an intelligent transmitter-receiver system, the cordless tool is connected wirelessly with the vacuum cleaner. The receiver is installed directly in the vacuum cleaner and attached to the suction hose. A vibration sensor in the transmitter then detects when the machine is switched on or off. If the vibration in the machine is not strong enough, the transmitter can be attached directly to the device using the multi tape included. “If the user starts operating his cordless tool, the vacuum cleaner will automatically start in parallel and, thanks to this innovative solution, the operator is very well protected from dust”, explains Koch.

For manual cleaning, it is just a matter of pressing the remote-control button on the transmitter, which is positioned directly in the front on the sleeve. This is particularly practical for classic floor cleaning applications, where professionals will often switch the vacuum cleaner on and off by hand.


Cross-manufacturer compatibility

Another great advantage of the CordlessControl system is the flexibility in combining cordless tools of all manufacturers with this cordless vacuum cleaner. This makes the system an optimal addition to the cross-manufacturer battery pack system CAS (Cordless Alliance System). Within this alliance, more than 160 machines and devices from 17 manufacturers are compatible and can be combined at random with one battery pack.
