Mosmatic TYR Fixed Duct Cleaners
The Mosmatic TYR is a fixed duct cleaner — a rotary arm built to spin inside ductwork and tight cylindrical spaces a flat-surface cleaner can't reach. CheapPartz carries it in two fixed diameters: the 20-inch 81.476 (SKU 6852) at $523.88 and the 24-inch 81.486 (SKU 6853) at $504.71, both rated to 4,000 PSI (prices at the time these pages were consolidated; live prices are on the variant cards below).
“Fixed” is the operative word. Unlike an adjustable surface cleaner, the TYR's diameter is set — you pick the size that matches the ductwork you clean. The 20" 81.476 suits smaller ducts and tighter runs; the 24" 81.486 covers larger duct interiors with a wider spinning path per pass. Both spin the same way inside the duct and carry the same 4,000 PSI rating, so the only real decision is diameter versus your duct size.
These are niche tools for duct-cleaning work — HVAC contractors, industrial maintenance crews, anyone running a pressure washer down a duct run. Confirm the diameter against the ductwork you'll be cleaning and the PSI rating against your machine before ordering.

Which Variant Should You Choose?
81.476 MOSMATIC TYR 20" FIXED DUCT CLEANER 4000PSI
Choose the 20" 81.476 for smaller ductwork and tighter runs where a 24" arm won't fit or can't spin freely.
81.486 MOSMATIC TYR 24" FIXED DUCT CLEANER 4000PSI
Choose the 24" 81.486 for larger duct interiors — a wider spinning path per pass in big duct runs.
Fitment
Match the fixed diameter to the ductwork you'll be cleaning, and confirm the 4,000 PSI rating against your pressure washer — don't run a machine rated above 4,000 PSI into either TYR.
Frequently Asked Questions
What's the difference between the 81.476 and the 81.486?
Only the diameter — 20" versus 24". Same 4,000 PSI rating, same fixed-duct-cleaner design.
Can I use the TYR as a regular surface cleaner?
It's built to spin inside ductwork and tight spaces a flat-surface cleaner can't reach — it's a duct tool, not a driveway tool.
How do I pick the size?
Match the fixed diameter to the ductwork you'll be cleaning. The size is set — there's no adjustment.
