The Drainvac Generation 2 2×520 AW is a dual-motor powerhouse delivering ultra-high suction in a compact, soundproofed unit — built for homes up to 790 m² (8,500 ft²) with a large 41L canister and muffler included.
Best for: Large homes requiring maximum suction power with the convenience of a high-capacity, low-maintenance system.
Two independent motors combine to deliver exceptional cleaning performance across large floor areas. The soundproofed casing and included muffler keep operation quiet, while the semi-transparent 41L canister lets you monitor debris levels at a glance. A permanent SMS filter provides long-lasting filtration without replacement.
⚠️ Safety note: Never vacuum flammable or gaseous material. Not compatible with Activac 3® filter. See user manual for full details.
⚠️ Maintenance note: Use of a dust bag and cage filter is mandatory — improper usage will void the warranty. Replace the dust bag when full. The cage filter can be hand-washed when the bag is changed — allow to dry completely before reinserting. Do not put in the dryer.

Frequently Asked Questions
Is a dust bag required?
Yes — a dust bag and cage filter are both mandatory. Operating without them voids the warranty. Replace the bag when full and hand-wash the cage filter at the same time. Do not put the filter in the dryer.
Can I use an Activac 3® filter with this unit?
No — this model is not compatible with the Activac 3® filter. See the user manual for compatible accessories.
What does outside exhaust vent mean?
Instead of recirculating exhaust air back into the room, the unit vents it outside the home entirely — eliminating any risk of fine dust or motor residue re-entering your living space.
How does the dual-motor system compare to a single-motor unit?
Two motors working together deliver significantly higher water lift (170 in vs 138 in on the single-motor 800 AW model), making this better suited for homes with longer duct runs or multiple floors.
