Frequently asked questions
How much floor can it clean per hour?
About 18,170 sq ft per hour in real use (TASKI practical figure). The theoretical maximum is 24,219 sq ft per hour.
How long does the battery last?
2 to 4 hours, based on battery type and mode (TASKI figure).
Gel or lithium: which battery should I choose?
Gel costs less and is maintenance free. Lithium costs more, but it charges faster, you can top it up at any break, and it lasts more charge cycles. If you clean in one long shift and charge overnight, gel is usually enough. If you clean in several shifts, choose lithium.
What is the difference between the 5 kits?
Battery type (gel, lithium 50Ah or 100Ah) and charging. BMS kits have an on-board charger (13A or 25A). The standard kits use an external charger.
How much does it weigh?
About 423 lb ready to use with gel batteries (TASKI figure).
How does it ship?
Machines this size ship by freight on a pallet. Tell us if you need a liftgate or inside delivery when you order. Call 877-449-0447 for a freight quote to your zip code.
