Frequently asked questions
How much floor can it clean per hour? In real use, about 19,980 sq ft per hour for the DD55 and 23,600 sq ft per hour for the DD65 (TASKI practical figures). Theoretical maximums are 26,641 and 31,484.
DD55 or DD65? The DD55 cleans a 22 in. path and the DD65 a 26 in. path. Choose the DD65 for wide open areas and the DD55 for areas with more turns and doorways.
Which pads fit? Two 11 in. pads on the DD55 and two 13 in. pads on the DD65. See the parts lists on this page.
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.
How much does it weigh? About 425 to 432 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.
