Big Brutes are big, tough industrial vacuum cleaners.

They're designed and manufactured by Michael Williams Engineering Ltd, near Cambridge, England, and have been helping British businesses clean up for decades.

Big Brutes are sold in England, throughout Europe, Australia and New Zealand.

Big Mike is the name for Big Brute in Canada.

Big Mikes are specially designed for Canadian businesses and their power supplies.

Big Mikes are made in England to the same rigorous standards as the Big Brutes.

Our History


Michael Williams founded his company.

The prime aims of the company was to develop a new and reliable way to establish the level of materials in silos and holding tanks, based on an existing design and patent held by the company.

This association with flowing materials of all sorts led onto other associated problems such as dust control and the need to clean up in production plants.

We started to design and manufacture fans and filter systems based on individual customers' requirements. This led to a sound in-house manufacturing base and a solid understanding of airflows, filters and waste handling.


Soon we were being asked to design a mobile fan with filter to attack the problem of site cleaning.

We looked around for a range of vacuum cleaners to supply this potential market. It very soon became clear to us that the vacuum cleaner range on the market was aimed at mass markets of hotels and small businesses.

So, with our in-house skills of airflow, design and manufacturing that we'd built up, we decided to bring out our own vacuum cleaning machine specifically for bigger industries.

We made our first prototype after some brainstorming sessions.

I'll never forget the first trial run. I attached 50ft. of hose with a 2.5 inch diameter to the inlet and switched it on. We were astounded at the performance of this machine. In minutes, it had cleaned the ancient muck and growing weeds - everything - within a 100ft diameter around the machine without even having to move it, all powered from a normal electrical wall outlet.”

Next day I was invited to take the prototype to two waiting customers, one a potato storage and processing company, and the other a potato retail supply company.

I came home with two orders.

We were on our way. I still have that prototype and it's still working in our factory.

1986 onwards

Our company philosophy is to listen to what the customer wants to achieve and to meet their requirements.

With our in house design and manufacturing ability we were soon increasing the Big Brute range to cover many industrial requirements into the fully customer tried and tested Big Brutes that are available today.


Today, Big Brutes are working world-wide in many industries ranging from warehousing and steel works to nuclear plants production processes and construction sites.

All our videos show the Big Brutes in action but the Big Mikes do the same jobs. Big Brutes have always been fitted with American-manufactured motors and the same applies to the Big Mikes.

So the history of Big Mike is the history of Big Brute and that goes back over 30 years over many parts of the word in many diverse industries.
