New Tornado Tempest Cordless 26" Carpet Sweeper Vac (Battery and Charger not included)
Our Take (from the SES Sales Team)
“The Tempest is a cordless wide-area carpet sweeper for big carpeted spaces where an upright is too slow and a cord is a hazard: hotel ballrooms, convention space, airport gate areas, office floors and school hallways. With the side brush, it cleans a 26 in path, and Tornado rates it at 19,375 sq ft per hour. It runs on the same 36 V, 7.5 Ah lithium-ion battery as the Tornado Strike upright and Zephyr backpack, rated at up to 60 minutes, and there is a spot on board to carry a second battery so the operator can swap and keep going. Brush pressure adjusts with a dial and LED indicator to suit the carpet, and a hard floor mode handles the transitions. The 5 gal dust bin lifts out, and the pre-filter cleans itself every five minutes so suction does not fade halfway through a big room. At 56 dBA it is quiet enough for daytime cleaning around guests and staff. Keep in mind that the battery and charger are sold separately, so add at least one of each to the order.”

How long does it run?
Tornado rates the Tempest at up to 60 minutes per battery. A second battery can ride on board so the operator can swap and keep going.
Does it work on hard floors?
Yes. It has a carpet mode and a hard floor mode, though it is designed mainly for wide-area carpet.
Can I use my Strike or Zephyr batteries?
Yes. The Tempest uses the same Tornado Cordless 36 V battery and charger as the Strike upright and the Zephyr backpack.
