Bin and filtration

3 of 6 differ

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. A dock bag that the maker calls the dust bin goes in the dock dust capacity.

FilteriPublished filter type or grade, such as "HEPA".

HEPA4Maker spec sheet (PDF)media3.bsh-group.com/Documents/28042962_BBS932GUC_Spec_Sheet.pdfRead 14 October 2026HEPA Filtration: Yes. Footnote says the HEPA filters keep more than 99.99 percent of dust from being released, tested to ASTM F3150 and IEC 62885-4:2020/A1:2023. The sheet names no particle size, so no capture claim is stored. The brush pick-up claim of over 99.9 percent is a different claim.

H12-grade HEPA1Maker product pageultenic.com/products/ultenic-u20-cordless-vacuumRead 15 October 2026Box list names 2 x H12-grade HEPA filters.

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

Particle capture (claimed)iShare of particles the maker says the vacuum captures, such as 99.99, at the particle size in the next row. Keep the test standard in the source note, such as ASTM F1977 or ASTM F3150. Compare only values with the same particle size. A claim with no particle size is left out.

Battery and run time

6 of 8 differ

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

18V2Maker product pagebosch-home.com/us/en/product/vacuum-cleaners/cordless-vacuum-cleaners/unlimited/unlimited9/BBS932GUCRead 14 October 2026Page lists Voltage 18.0 V.

29.6V2Owner's manualcdn.shopify.com/s/files/1/0362/1804/4549/files/U20_EN.pdfRead 15 October 2026Printed page 4 specification: working voltage 29.6V. This is the nominal pack voltage of 8 cells at 3.7 V.

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.

3,000mAh2Maker product pagebosch-home.com/us/en/product/vacuum-cleaners/cordless-vacuum-cleaners/unlimited/unlimited9/BBS932GUCRead 14 October 2026Page lists Battery capacity 3.00 Ah, which is 3000 mAh. The spec sheet says 1 battery (1x 3 Ah).

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.

Removable batteryiThe user can remove and swap the battery without tools, such as a click-in battery. Service replacement does not qualify.

Yes2Maker product pagebosch-home.com/us/en/product/vacuum-cleaners/cordless-vacuum-cleaners/unlimited/unlimited9/BBS932GUCRead 14 October 2026Page lists an exchangeable battery pack.6Owner's manualmedia3.bsh-group.com/Documents/8001366453_A.pdfRead 14 October 2026Section 4.6 and the battery list name genuine PBA 18V 3.0Ah and 4.0Ah packs that insert and remove.

11Maker product pageultenic.com/products/ultenic-u20-cordless-vacuumRead 15 October 2026Box list says 1 x battery.

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.
