PowerMAX Canisters
PowerMAX canister models were introduced in 1993
as replacements for Spectrums, which they resemble
in appearance.
ALL PowerMAX canisters have power nozzles.
Nozzle motors are turned on (rug) and off (bare) at the
hose grip.
Power nozzles packed with PowerMAX models are all
the style shown at the left with two brush brush roll,
headlight and belt check window,
All nozzles used with the PowerMAX have a belt check
window on the top.
On all models (on/off on unit or hose) the hose must be
plugged into the P.T.O. receptacle of the cleaner
before the canister will operate.
Variable speed motors are in some PowerMAX models.
Motor speed can be varied on the unit on some models
and on the hose on others. See drawings.
ALL POWERMAX models:
• Use Type "S", 7 quart, micro filtration T/A bags (std
"S" bags will work)
• Have reusable secondary filters in the bag cavity to
catch any fine dirt which may get past the T/A bag,
These filters can be washed in warm water.
• Have washable micro filters to clean exhaust air
even more before it is returned to the room. See
drawing.
• Have 25' cords on a cord reel
• Have covered tool storage on the cleaner
• Include a 4 piece tool set
• Have "check bag" indicators
4/93
• Have bag lid hinges designed to break away if the
lid is opened too far
