CLEANING PATTERNS
For regular carpet cleaning use an overlapping arc pattern three times over the same
area (two passes with solution and one pass for drying). When cleaning carpets, first
clean in circular pattern, then use the overlapping arc pattern to dry the area.
Dirtiest areas may require two or more cleaning passes. Using either pattern
shown in Figure 4-4, you should develop a comfortable rhythm. To obtain
maximum performance from your RX20, move it slowly and deliberately with
a 50% overlap, giving it time to clean and extract. A steady pace rather than a
frenzied one will increase efficiency and production, and decrease fatigue.
The following cautions should be observed while cleaning:
1. DO NOT operate your RX20 over metal floor moldings. Damage to both the
molding and the cleaning head will result.
2. DO NOT operate your RX20 on hardwood floors.
3. DO NOT operate your RX20 over loose or unraveled carpet seams. The
cleaning head may catch and cause further damage.
4. DO NOT operate your RX20 on concrete floors unless a hard-surface brush is
installed. It will develop sharp edges on the extraction heads that will damage
carpet fibers.
5. DO NOT clean over the edge of a loose carpet. Instead, clean only up to the
edge. Damage may occur if the extraction heads catch the loose carpet.
