SeaVac Mini
Model CS-8
One cutout, one outlet. The simplest install on the water. Self-contained: the inlet is built into the face of the unit. Plug it into a cabin outlet and it is ready.
- One cutout and a 6 ft cord into a nearby outlet — the whole install
- Hose plugs straight into the face of the unit
- Takes the Y10 single-opening bag
Best for: Small cabins, V-berths and weekenders where there is no room for a pipe run. Takes the Y10-5 dust bag.

Shown as it ships: the SeaVac Mini is InterVac’s model CS-8, and the power unit carries the RoadVac name on its front panel. Same unit, same bag, same parts.

A VacPort will not work with the SeaVac Mini. The inlet is built into the face of the unit, so there is no pipe run for a second cleaning point to join. Inlet valves, couplings, fittings and installation hose do not apply either. If you want a VacPort, the model you want is the SeaVac Mini Pro.

Consumables
The Y10 bag is the one that seals.
The SeaVac Mini takes the Y10-5 — five bags and one motor filter. Change the motor filter after every fifth bag, which is why one ships in every pack. Non-genuine bags and filters void the vacuum warranty.
No hose or tools aboard? That is normal. Plenty of boats get the vacuum fitted without the hose and tool kit, because the kit is sold separately. Nothing is wrong with the system — any 32 mm kit fits. Tool kits from $125.05.
SeaVac Mini questions
Common questions
Which dust bag fits the SeaVac Mini?
The Y10-5. It is the Y10 bag in a pack of five with a motor filter. The other SeaVac bags look similar but will not seal in this unit, so check the model number on the collar before you order.
Can the SeaVac Mini pick up water?
No. It is a dry vacuum for cabin use only. Never use it on water, bilge water, wet sand or anything damp, and mount the power unit in a dry compartment.
Can I put a VacPort on the SeaVac Mini?
No. The inlet is built into the unit and there is no pipe run to connect a VacPort to. The SeaVac Mini Pro takes VacPorts.
What tool kit fits the SeaVac Mini?
Any 32 mm kit — every kit InterVac sells. The TK108-B, TK108-TB and TK108-TBM all fit, as do the individual hoses, wands and tools.
Why does my SeaVac Mini say RoadVac on the front?
The SeaVac Mini is InterVac’s model CS-8, the same power unit InterVac sells for RVs under the RoadVac name. It ships with that front panel. The bag, filters and parts are identical.
