What makes the 350 a “soot Vacuum”?

Chimney sweeping applications have some unique requirements that are not seen in many other sectors, this compact machine has been designed to meet those requirements. 

• Storage For Hose & Cable - When working in peoples homes it is important to keep carpets and furniture clean, it is, therefore, more important than ever to have somewhere to store the cable of the machine and hose neatly. The handle offers a neat and secure way to store both the hose and cable, preventing them from falling on furnishings and leaving black sooty marks.
• Compact Size - When cleaning in the home there is not always a lot of space, the compact size of this machine means that access is not an issue. Durable Construction - The machine is designed to take the bumps and knocks associated with being transported in a van whilst travelling from site to site several times a day. It is all steel in construction and therefore very hard wearing.
• H13 Filtration - Prevents the hazardous, carcinogenic dust generated by sweeping being inhaled by the operator. The vacuum is supplied with a certificate stating that it is H13 rated. 
• Comprehensive Accessory Kit - Designed for detailed cleaning and general extraction of dust from a fireplace whilst cleaning. 
• Removable Trolley - When access is really very tight the vacuum can be disconnected from the trolley making the vacuum lighter and more practical in a compact, confined placed. The wheels of the trolley also mean it can be wheeled to and from properties with ease.

What other Accessories are available for this Chimney Sweep Vacuum?

There are many optional accessories, but we find the floor tool kit to be one of the most useful accessory additions. This floor toolset makes cleaning larger areas of flooring very easy and quick. It is more suited to those who are cleaning commercial or industrial boilers or furnaces.
