Cleaning points
Two ways to pick up dirt.
The Ultra Max is a piped system, so it takes both. An inlet valve is where the hose plugs in. A VacPort takes the place of a dust pan — open its door and the vacuum starts, then sweep the dirt straight into it and it travels down the pipe to the dust bag. No hose, no bending down.
The complete install kit, the A-950-X, is $65.96 and includes the LED VacPort, trim plate, elbow, coupling, sweep tee, 3 ft of hose, wire and nuts.

Consumables
The Y09 bag is the one that seals.
The Ultra Max takes the Y09-5 — five bags and one motor filter. No other bag fits it: the Y08, Y10 and Y11 look similar but will not seal in an Ultra Max.
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 tools with your coach? That is normal. Plenty of RV builders fit the vacuum at the factory but leave the hose and tool kit out, because the kit is sold separately. Nothing is wrong with your system — you just need the kit. Any 32 mm kit fits.
Ultra Max questions
Common questions
Which dust bag fits the Ultra Max (RMD)?
The Y09-5. It is the Y09 bag in a pack of five with a motor filter. The other RoadVac bags look similar but will not seal in this unit, so check the model number on the collar before you order.
How do I order an Ultra Max?
Call 772.463.1400 or email [email protected]. It is built to order, so tell us the coach and whether you need the complete system or a replacement unit only, and we will come back with a price and a lead time.
Can I put a VacPort on the Ultra Max?
Yes. It is a piped system, so it takes the VacPort range in LED and non-LED, plus inlet valves.
What tool kit fits the Ultra Max?
Any 32 mm kit, which is all of ours. The TK108-B, TK108-TB and TK108-TBM all fit, as do the individual hoses, wands and tools.
