Notes

The Power Unit should have a dedicated circuit.

All models 240V 50/60HZ
SEPARATE CIRCUIT RECOMMENDED

F700T2 and S900 can be open bag or TruSeal models.

Loss of CFM per 75 ft pipework = 2%
1 x sweep elbow ≡ 5 ft tubing
1 x 45 deg elbow ≡ 2.5 ft tubing

For using air power brushes on full pile carpets a machine with high water lift is required.

Using dust free disposable bags requires no outside venting and extends motor life. An exhaust run adds pressure to the motor. If desired to use an exhaust run the maximum length is 30 feet. Please note that if this is not a straight run each 90 degree sweep is the equivalent of 5ft of pipe. eg 20 ft of pipe and 2 x 90 degree runs is equivalent to 30 feet of pipe.

Even though your house size/installation needs only a small amount or pipework if you have a lifestyle that requires regular, prolonged heavy-duty cleaning (e.g. heavy traffic with pets, children, visitors etc.) then it is better to have a more powerful motor that is less stressed.

Factors other than Air Watts should be taken into consideration including: altitude, amount of hours of daily usage, complexity of pipe installation, length of furthest vacuum inlet, noise level desired, type and size of filtration, country of origin, construction materials, and budget. The square footage recommendations on this page are solely based upon the suction capabilities of the unit.
