Which is better for pet hair?

Both use the DuoClean Detect nozzle with two brushrolls and are rated for pets, so hair pickup is close. B adds LED lights that help you spot hair on dark floors, and its larger bin means fewer empties on a full-house pass.

Is the IP1251 worth the extra $45?

If you want LED lights, a 5-year warranty and a bigger dust cup, yes. If you mainly do quick daily cleans and want the lighter machine, A covers the same core cleaning tech for less.

Which is easier to carry upstairs?

A, at 7 lb versus 8.2 lb for B. The 1.2 lb gap is noticeable when you clean a full staircase or lift the vacuum overhead.

Do both run 70 minutes?

Yes, both are rated up to 70 minutes in ECO mode, measured at the hand vac. Expect much shorter runtime in Boost mode, where suction peaks.

Which has better filtration?

Both are HEPA-certified. B adds a washable foam pre-motor filter ahead of the HEPA post-motor filter, which can reduce how often you replace the HEPA element.

B carries a 5-year warranty with 2 years on parts; A's listing does not state a warranty. That makes B the safer long-term bet, though both share the same battery platform and charge in about 6 hours.
