Ryobi RS290G 5 in. Random Orbit Sander: problems, parts and running costs

Checked: 2026-10-20

Summary

The RS290G is a corded 5-inch random orbit sander with a 2.6-Amp motor, 12,500 orbits per minute, a hook-and-loop pad, a dust bag in the box and a three-year warranty, sold direct by Ryobi for $69.00. Its recurring complaints are design limits rather than defects: no variable speed, only fair stock removal and dust collection on its own, a dust bag that fills fast, and no official replacement-parts channel for the model. Running cost is sandpaper discs plus the occasional backer pad, with no battery or subscription, and it is a good buy at or below about $65 for someone who sands occasionally.

Common problems and fixes

Dust collection is only fair, and the bag fills quickly — in the Fine Woodworking test of 11 five-inch random orbit sanders the Ryobi was rated fair on both stock removal and dust collection, and the on-board bag fills fast enough to interrupt a long session. Fix: attach a shop vacuum; every sander in that test, this one included, “worked significantly better when connected to the vacuum” and removed stock more aggressively with a hose on. Empty the bag often if you work without one. [4][5]
The rear can tip when a vacuum hose is attached — the fine dust-port scoop that leaves room to grip the sander at the waist is also where a hose can catch, so the back of the tool can tip when you rotate it a lot. Fix: rotate the sander slowly and keep it flat, or sand in shorter sessions without a hose. [4]
Power loss and a wobbling base — one owner reported that the sander “worked for about 3 months and then it started to lose power when sanding”, with a base wobbling so badly the tool could not be used; the owner also missed the return window. Only that single failure report could be read, so no failure rate can be estimated, and no switch, motor, bearing or cord failure has been reported for this model. Fix: return a failing sander inside the three-year warranty period and keep the receipt. [1][9]
No official replacement parts and no manual — Ryobi’s own replacement-parts store returns zero products for RS290 and RS290G, and no manual PDF for the model could be located, so there is no visible route to a replacement motor, switch, dust bag or backer pad even though Ryobi sells the pad and the paper as accessories. Third-party parts sites do carry RS290 and RS290G in their compatibility data. Fix: buy consumables from Ryobi direct and treat a dead motor as a write-off. [1][7][10]
The 12,500 orbits per minute figure is a free-running number — Ryobi states it without a no-load qualifier, and no independent measurement of this sander’s orbit speed, noise or stop time was published, so it cannot be used to judge grit removal. Fix: none; judge the tool on the grits you actually use. [1][4]
No recall covers this model — the Ryobi recall-notices page lists a recall only for the S651D 1/4 sheet sander sold 2005–2010 and nothing for RS290 or RS290G, so buying used carries no recall risk. [8]

Parts and consumables

5" Backer Pad for Orbital Sanders (A21BP01) — $16.97 at ryobitools.com, October 2026; replace when the hook-and-loop face stops gripping discs. No replacement interval is published, and the pad is not listed in Ryobi’s replacement-parts store, only on the product page. [1][7]
7 PC. 5" Random Orbit Sander Sand Paper (A21701) — $6.47 at ryobitools.com, October 2026; the main consumable, a seven-piece assortment of 5-inch hook-and-loop discs and the only paper the manufacturer sells for this machine. Replace discs as they wear through; no usage rate is published. [1]
No battery, charger or platform — the RS290G is a 120 V corded tool, so there is nothing platform-specific to buy, nothing to age in a drawer, and no battery cost over the life of the machine. [1][3]

Yearly running cost

Spending is consumables only: 5-inch hook-and-loop discs, with the manufacturer’s seven-piece assortment at $6.47 (ryobitools.com, October 2026), plus an occasional 5-inch backer pad at $16.97 (ryobitools.com, October 2026). The tool is corded, so there is no battery or charger to replace and the electrical cost is trivial. No owner-reported annual spend and no disc consumption rate were captured, so a per-year dollar figure cannot be computed from the sources; the more you sand, the more discs you burn through. [1][4]

When it is a good buy

Ryobi sold the RS290G for $69.00 direct from ryobitools.com in October 2026; Fine Woodworking’s test priced it at $65.00 in 2018, and Family Handyman recommended it at about $60 in 2022. No big-box street price could be read, because Home Depot, Lowe’s and Acme Tools blocked access, so treat the $69.00 direct price as the reference point. [1][3][4]

Thresholds from the same research:

At or below about $65 — good value; the independent testing supports a positive verdict at that level.
$66–$75 — fair to good, which is where the $69.00 direct price sits.
$76–$90 — weak, because against that money a buyer can step up to variable-speed machines.
Above $90 — poor value for this model. [1][4][5][6]

Named alternatives:

Makita BO5041 — $129 in the Pro Tool Reviews roundup, variable-speed with published vibration data; the better choice when speed control and low vibration matter more than price. [6]
Festool Rotex FEQ-Plus — $549.00 in the same test, where it was named Best Overall; the better choice when professional dust collection and stock removal justify a large jump in price. [4]
