Verdict

The Rowenta Compact Power RO3945EA is a corded, bagged canister vacuum cleaner featuring a 750W motor (reaching up to a 900W maximum) that provides efficient deep cleaning across carpets and hard floors. Main advantages include its ultra-compact, lightweight frame (under 4 kg), a highly protective 2-stage filtration system that captures 99.98% of dust, a generous 3-litre Hygiene+ dust bag capacity, and an 8.8-metre operating radius backed by a 6.2-metre power cord. However, reported drawbacks include a relatively high operating noise level of up to 75 dB(A) at maximum power and a limited main floor brush design that can sometimes push larger debris forward on hard surfaces instead of immediately vacuuming it up.
