  • CH520 is rated 4.4 out of 5 by 5.
    Rated 2 out of 5 by from OK but not as good as the old model This hose replaces a 14 year old Nutone one that finally cracked. It is very flexible, to the point where it can occasionally "kink" when bending. We purchased another hose (non-Nutone) at the same time and it has the same construction weakness. Caution - if you want to use the Nutone hose with a power rug cleaner (CT700), you have to order the correct handle (CT170).

    Rated 5 out of 5 by from great product The Current carrying hose is a great product and works perfectly. Just one thing to know is when ordering this product, be sure to order the model that works with your central vacuum inlets and the wand. I found that it wasn't made very clear when ordering.

    Rated 5 out of 5 by from Super Company A vast improvement over the 20 year old hose it is replacing. Great product and company supplying it.

    Rated 5 out of 5 by from Excellent replacement for M & S This unit was a virtually perfect replacement for my 25 year old M & S hose. The end that plugs into the wall was identical. The nozzle end fits my existing wands perfectly though it is slightly re-styled. (Note, some people might have to drill a new catch hole in their wand depending on the style.) For people looking for hose replacement for M & S systems, this item is the best one I have found.

    Rated 5 out of 5 by from Pleased as punch! My new hose is so much easier to use than the older model. I love that it is much lighter and the handle is so "user friendly"!

  • Loose electrical connection

    I posted this question under CH515 but then realized that the hose I have is CH520 (not CH515) - and I have CT700 power brush. The electrical connection is failing due to arcing because of play in the latch. There are no loose parts and both components are otherwise working fine. Is there a way to fix this? My unit is our of warranty.

    Of course I am using the CT175 wand. Why would you assume that I was not using a wand? The power brush came with it. It is the only one that fits it. The problem is electrical connection between the wand and the hose. There is play between the two. Please do not avoid answering the real problem. How can I fix it? Is the replacement any better?

    my old system has a current carrying hose if I purchase the CH hose how do I attach the new hose to my vacuum I think the model number on my current s

    If the CH515 is not correct what hose do I need to purchase
    Asked by: need help
    Thank you for your question on the central vacuum system hoses. If you presently have a current carrying hose that has a six foot pigtail on the wall end of the hose that plugs into an electrical outlet, the new hose would be the CH515. Please contact the Technical Service Department at 888-336-6151 for further assistance.

    If I purchase a CT700 power brush with the CT175 retractable hose, will my discontinured CH520 hose work with those?

    Asked by: B
    Thank you for your question. You can use the CT700 with your CH520, but you will need to use the CT170 wand. The CT175 is not compatible with the CH520.

    I wanted a 20FT A/C Powered Cord so I can use my brush head attachment. I can not locate any hose this length. Where can I find one?

    What is involved to shorten a 32' hose to a 25' hose with A/C power cord?
    Asked by: C. Leise
    Thank you for your question on the CH520 central vacuum hose. The CH520 hose is 30 feet long and cannot be shortened. We do not have a shorter hose and have no way to modify one.

    Loose electrical connection - contd.

    I am using the wand - I have is CH520 hose. I use it with CT700 power brush and CT170 wand. The electrical connection between the hose and wand is failing due to arcing because of play in the latch between the two. This play was always there but over time it has damaged the electrical prongs due to arcing. There are no loose parts. Is there a way to fix this? My unit is our of warranty.

    Thank you for your question on the model CH520 central cleaning system hose, CT700 electric power head and CT170 wand. These three parts work together and they should fit together tightly, without play. There are no repair parts for the wand. If there is play between the wand and hose, and the wand is the problem, it would need to be replaced. Please contact the Technical Service Department at 888-336-6151 for further assistance.
