Koblenz P-820 vs P-1800 Specs
Motor and Speed
Both machines use a 4.2 amp motor, providing equal power for demanding cleaning tasks. However, the Koblenz P-820 BA specifies a brush speed of 1100 RPM with three adjustable settings. This allows you to switch between low speed for gentle polishing and high speed for deep carpet shampooing. The P-1800 lists its 4.2 amp motor but does not disclose its RPM or speed options. If you need variable speed control for different surfaces, the P-820 BA offers more precise adjustments for your specific cleaning needs.
Handle Height
Ergonomics matter when scrubbing floors for extended periods. The Koblenz P-820 BA features a handle height of 25.5 inches, which is a compact size suitable for lower ceilings or smaller storage spaces. In contrast, the Koblenz P-1800 has a significantly taller handle at 44 inches. This taller design is better for users who prefer to stand upright while working, reducing back strain. If you are tall or want to avoid bending over, the P-1800 provides a more comfortable working posture for daily use.
Included Accessories
The P-820 BA arrives ready to work with a comprehensive kit. It includes shampoo brushes, scrubbing brushes, polishing pads, and lambswool buffing pads, plus bottles of carpet shampoo, fabric shampoo, and heavy-duty neutral cleaner. The P-1800 includes two sets of scrubbing brushes and two pairs of polishing pads but does not list any cleaning solutions. If you want to start cleaning immediately without buying extra supplies, the P-820 BA offers a more complete out-of-the-box experience with essential chemicals included.
Weight and Maneuverability
The P-1800 weighs 14 pounds, a specification clearly listed in its data. The weight of the P-820 BA is not provided in the available data. The P-1800 also features twin brushes that rotate in opposite directions, designed for easier handling and reduced torque kickback. This counter-rotating system can make the machine feel more stable on hard floors. Without weight data for the P-820, the P-1800 has a clear advantage in terms of documented maneuverability features and known mass for transport.
Physical Dimensions
Both units have a 12-inch cleaning width, covering the same floor area per pass. However, their overall footprints differ. The P-820 BA is shorter, measuring 11.4 inches in length and 25.5 inches in height, making it easier to store in tight closets. The P-1800 is longer at 13 inches and much taller at 44 inches. If you have limited storage space or need a more compact machine for vertical storage, the P-820 BA is the more space-efficient choice due to its smaller overall dimensions.
Choose your Koblenz carpet cleaner
You want adjustable speeds for different tasks
The P-820 BA offers three speed settings on its 4.2 amp motor. You can switch between low for gentle polishing, medium for scrubbing, and high for deep shampooing. This flexibility lets you tailor the 1100 RPM brush speed to specific floor types, from delicate hardwood to heavy carpet, without needing multiple machines.
You prefer a taller handle for standing use
The P-1800 features a 44-inch height, allowing you to clean while standing upright. This design reduces bending and strain on your back. The twin brushes rotate in opposite directions for easy handling. Its 12-inch cleaning path covers ground efficiently, making it a practical choice for large areas where comfort matters.
You need included cleaning solutions and pads
The P-820 BA kit includes carpet shampoo, fabric shampoo, and heavy-duty neutral cleaner. It also comes with shampoo brushes, scrubbing brushes, polishing pads, and lambswool buffing pads. You can start shampooing, scrubbing, polishing, and buffing immediately. This all-in-one approach saves trips to the store and ensures you have the right tools for every surface.
You want a lighter machine for storage
The P-1800 weighs 14 pounds, making it manageable for storage and transport. Its white and black color scheme is simple and clean. The 4.2 amp motor provides sufficient power for routine maintenance. If you prioritize a compact footprint and straightforward operation over adjustable speeds, this model offers a reliable, no-frills solution for your cleaning needs.
