Amazing

Amazing (most probably) because of the technique I used to clean a carpet which was very dirty (traffic area, no pets).

Here's the technique:

1. Use very hot water.

2. Clean the dirty spots using 'Folex Instant Carpet Spot Remover' = http://www.folexcompany.com/

3. Push the Bissell -with the trigger on- to dispense the cleaning solution by covering 4 feet in about 4 seconds.

4. Now, with the trigger off, take 30 to 40 seconds to pull the machine back by jiggling the handle in a zigzagging motion. (Moving the handle 12 inches from left to right will cause the brushes to scrub the carpet area with an amplitude of about 2 inches from side to side).

5. Repeat until clean.

Results: The first 3 runs saw the water turning from ink black to dark gray. A few more runs (with spot cleaning on my knees) and the carpet became like new.

Conclusion: This week I'm gonna return the machine to exchange it for a real contender: one with rotating brushes. That should save me from jiggling the vacuum around.
