RYOBI P411: problems, parts and running costs
Checked: 2026-10-20
Summary
The P411 is discontinued on RYOBI’s site, and the only owner evidence is five reviews on that page: one unit stopped starting after 10+ years and one bundled battery would not hold a charge. Sandpaper is the recurring cost, at $6.47 for a seven-piece set. It is a reasonable buy only if you already own 18V ONE+ batteries and pay clearly less than the supported PCL406B.
Common problems and fixes
- Unit stops starting after long use — one owner of a 10+ year-old sander reports it “used to start up for me with a little spin of the sand paper head and now, nothing”; that is a single report, not a failure rate, and a tool that old is outside the 3-year warranty. [1]
- Bundled battery will not hold a charge — one owner bought a bundle special and reports the included 2 Ah battery would not hold a charge and had to be returned; batteries carry a 3-year warranty. [1]
- Discontinued with no add-to-cart — RYOBI marks the P411 Discontinued and shows no way to buy it, though the page still carries a $44.97 reference price; availability of P411-specific spares is unconfirmed. [1]
- Listing may ship a different generation — “40% Reduced Vibration” and “Hook & Loop Sanding Pad” are wording from the newer PCL406B, not the P411 page, so check the model number printed on the tool. [1][2]
Parts and consumables
- 7-piece 5-inch hook-and-loop sandpaper set (A21701) — $6.47 at RYOBI, October 2026; 80/120/220 grit with pre-cut dust holes, replaced as discs wear. [3]
- 5-inch backer pad (A21BP01) — $16.97 at RYOBI, October 2026; a replacement pad for 5-inch random orbit sanders. [4]
Yearly running cost
The recurring cost is sandpaper: a seven-piece set is $6.47 at RYOBI (October 2026), so a few discs a month keeps the yearly spend to a small fraction of the tool price. A battery is the biggest single outlay for someone without 18V ONE+ gear — RYOBI lists a 4 Ah 2-pack at $149.00 (October 2026) — but that is a one-time purchase. No dust-bag or filter cost is documented for this model, so no firm yearly figure can be given beyond sandpaper.
When it is a good buy
- At the $44.97 reference price RYOBI still publishes for the tool-only P411 (RYOBI, October 2026), it is a cheap entry to 5-inch random orbit sanding for anyone already on the 18V ONE+ platform.
- Above roughly $90 it stops making sense: the brushless HP version of the same format is listed at $129.00 (RYOBI, October 2026). [5]
- RYOBI PCL406B — the current 5-inch random orbit sander at $59.97 tool-only (RYOBI, October 2026); the better choice when you want an in-production model with the same 10,000 OPM and 3-year warranty. [2]
- RYOBI PCL406K1 — $124.00 with battery and charger (RYOBI, October 2026); the better choice if you own no 18V ONE+ batteries. [1]
- RYOBI PBLSD01B — $129.00 brushless HP sander (RYOBI, October 2026); the better choice if you want a brushless motor. [5]
