22-Inch vs 15-Inch Scrubber Specs
Cleaning Width
The Purilitzs T381 offers a 22-inch cleaning width with a 33-inch squeegee. This wider footprint allows you to cover more ground in a single pass. The Dapper Supply model provides a 15-inch cleaning width paired with a 17-inch squeegee. A narrower width improves maneuverability in tight aisles and small rooms. You should choose the wider unit for large open warehouses or big retail floors where speed matters most. The smaller unit is better for narrow corridors, offices, or compact spaces where turning radius is critical. Your facility layout dictates which width serves you best.
Tank Capacity
Tank size determines how long you can clean before refilling or emptying. The Purilitzs T381 features a massive 15.9-gallon solution tank and an 18.5-gallon recovery tank. This large capacity minimizes interruptions during extended cleaning sessions in big commercial spaces. In contrast, the Dapper Supply scrubber has a 1.2-gallon solution tank and a 1.5-gallon recovery tank. While sufficient for smaller areas, you will need to refill and empty it much more frequently. If you are cleaning a large warehouse, the Purilitzs capacity is a significant advantage. For quick cleanups in small offices, the Dapper Supply size is adequate.
Runtime
Battery runtime affects how much floor you can cover in one charge. The Purilitzs T381 delivers 3 to 5 hours of runtime on a full charge. This long duration supports continuous cleaning for large facilities without frequent stops. The Dapper Supply unit provides up to 90 minutes of runtime. While 90 minutes is sufficient for smaller spaces, it limits the area you can clean in one go. You should select the Purilitzs T381 if your cleaning routes are long or cover extensive square footage. The Dapper Supply runtime is suitable for smaller, contained areas.
Weight and Portability
Weight impacts how easy the machine is to move and store. The Purilitzs T381 weighs 299 pounds. Its substantial weight provides stability during scrubbing but makes it difficult to transport or store in tight spaces. The Dapper Supply scrubber weighs only 22 pounds. This lightweight design allows you to carry it easily, move it between floors, or store it in small closets. If you need to maneuver the machine frequently or store it in a compact area, the Dapper Supply is far more practical. The Purilitzs is better suited for permanent or semi-permanent placement in large spaces.
Motor Power
Motor power influences scrubbing intensity and suction strength. The Purilitzs T381 uses dual 550W motors for both brushing and suction. This high power ensures strong water recovery and effective cleaning of heavily soiled floors. The Dapper Supply model features a 70W suction motor. While adequate for light dirt in clean environments, it lacks the raw power for tough grime. You should choose the Purilitzs T381 for industrial settings or floors with significant dirt buildup. The Dapper Supply motor is sufficient for maintaining cleanliness in offices or retail stores with light traffic.
Which Floor Scrubber Fits Your Space
Large warehouse operator needing high coverage
The Purilitzs T381 offers a 22-inch cleaning width and a 33-inch squeegee for wide-area efficiency. Its 18.5-gallon recovery tank and 15.9-gallon solution tank reduce refill stops during long shifts. Dual 550W motors provide strong suction and brush power. With 3 to 5 hours of runtime, it handles large commercial floors like warehouses and factories without interruption.
Small office manager prioritizing portability
The Dapper Supply scrubber weighs only 22 pounds, making it easy to move through narrow aisles and tight spaces. Its 15-inch cleaning width fits smaller commercial areas like offices and retail stores. The compact design includes a 1.2-gallon solution tank and 1.5-gallon recovery tank. At just 65 dB, it operates quietly for daytime cleaning without disrupting staff.
User with limited storage capacity
Space is at a premium? The Dapper Supply unit measures 17 inches wide and 17 inches long. This small footprint allows for easy storage in closets or under counters. In contrast, the Purilitzs T381 is significantly larger at 34 inches wide and 43 inches long. If your facility has tight storage constraints, the compact dimensions of the 15-inch model are a practical advantage.
