Rated poweriElectrical power of the vacuum as the maker publishes it, called motor power, rated power or wattage. It is not suction power in air watts.

Dustbin capacityiCapacity of the bin on the vacuum. Makers state the gross volume or the volume up to the max line. When both are given, the max-line volume is stored and the gross volume goes in the source note. A compaction claim, such as "holds three times more", is not stored.

Sealed filtrationiThe maker states that the whole machine is sealed, so all air passes the filter before it leaves.

Yes10Measurementvacuumwars.com/is-the-shark-powerdetect-clean-and-empty-any-goodRead 15 October 2026Review says the PowerDetect incorporates the complete-seal filtration technology, which passed the Vacuum Wars fog evaluation.

Battery and run time

Battery voltageiNominal pack voltage, such as 25.2 V. A full-charge voltage, such as 29.4 V for seven cells, is not nominal.

Battery capacityiPublished pack capacity at the nominal battery voltage. A cell count times a cell capacity, such as "8 x 3,200mAh", is not a pack capacity. The cell capacity is the pack capacity only when all cells are in series. That holds when the pack voltage divided by the cell count is one lithium-ion cell voltage, 3.6 or 3.7 V, such as 8 x 2,200mAh at 29.6 V. The source note shows the check. When the maker gives a rated and a nominal capacity, the one that matches its stated Wh at the pack voltage is stored.

3,750mAh1Maker product pagesharkninja.com/shark-powerdetect-cordless-stick-vacuum/IP1251.htmlRead 15 October 2026Spec list says amperage 3.75 amps, which is read as 3.75 Ah on the 21.6 V pack.

2,200mAh2Owner's manualcdn.shopify.com/s/files/1/0362/1804/4549/files/U20_EN.pdfRead 15 October 2026The manual states no capacity. The maker pages list a battery of 2200mAh*8, which are eight 2200 mAh cells. Eight cells at 3.7 V make the 29.6 V pack only in series, so the pack is 2200 mAh, about 65 Wh. A 36V 0.5A charger fills 65 Wh in about 4 hours, as the manual says. No maker document states the 2200 mAh pack figure.

Run time (claimed)iOne row per maker run time claim on one battery. Power level puts the maker's mode on a common scale. Lowest is the weakest setting, such as Eco or Min. Highest is the strongest, such as Boost, Max or Jet. Middle covers every setting between them. Claims that add a second battery are not stored. A handheld configuration without a motorized head counts as non-motorized tool. On hard floor with the main head counts as motorized floor head. Leave the tool out when the maker says neither or its own pages disagree, and name them in the source note. A machine with one power setting uses highest. When the maker gives a range, such as 20 to 25 min, the top of the range is stored and the range goes in the source note. A boost button or trigger counts as a setting, so a machine with one setting and a boost has a lowest and a highest row. A wet cleaning mode, such as Dyson Wet or Samsung WET, is not a power level, so it is not stored.
