Notes

All models 240V 50/60HZ
SEPARATE CIRCUIT RECOMMENDED

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. (Dual line max 30 ft if venting.)

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.
