Drainvac Broan-Nutone 550
Score: 73/100
OVO Central Vacuum
Score: 72/100Rankings

The Drainvac AP5501 delivers 550 air-watts of suction with whisper-quiet 66 dB operation, making it suitable for homes up to 4,000 sq ft. Its 22-lb weight and reliance on disposable bags can be drawbacks for some users. Ideal for allergy sufferers who value quiet, powerful whole-house suction.

The OVO 630ST-25H offers 630 AirWatts of suction, hybrid filtration and a quiet 60 dB operation for homes up to 5,000 sq ft. Its limited inlet count, scarce review data and relatively heavy unit are notable drawbacks. Best suited for large households that value flexible filtration and low noise.
