    Overall Review

    Nutone CV850 is best-suited with regards to lighter commercial applications or bigger homes. Homes having areas up to 12000 sq. ft. can do well with CV850. It has been provided with 2 three-stage motors. As such, more power gets packed in compact package.

    The other interesting feature is inclusion of a big, eight-gallon capacity ‘dirt-receptable’ bag. The system, on the whole, consists of 2 mufflers, system status indicator light, and sound insulation.

    Materials used for construction are such that one need not worry about its maintenance at least for the next 9-10 years. The finest feature of CV850 is that the user need not be a technocrat to operate it. Just glancing through instruction manual would make all the difference. This manual has been penned down keeping the forte of common man in mind. The language used is plain and lucid.
