Roborock Qrevo Edge 2: problems, parts and running costs

Checked: 2026-10-19

Summary

The Qrevo Edge 2’s recurring problems are physical and placement-related: thresholds over about 20 mm (0.8 in), obstacle avoidance below the category average, a 240 mL dustbin that can fill before docking, and occasional failure to return to the dock. Running costs are the consumables — dust bags, mop pads, side brushes, filter, main brush and cleaning solution; one owner’s three-month test went through roughly 6 bags, 5 pads, 3 brushes, 3 filters, 2 main brushes and 4 bottles per year and rated the annual cost tier low. At the official $1,099.99 (Roborock US, checked 2026-10) it is a strong buy at or below that price; above $1,250 the Saros line is the rational comparison.

Common problems and fixes

Thresholds over about 20 mm (0.8 in) — two hands-on tests put the practical limit there, and PCWorld’s unit failed on a real threshold even after registering it in the app; the chassis is rigid and has no Saros-style climbing feet. Fix: keep room transitions under about 20 mm or plan a ramp. [5][6]
Obstacle avoidance is below average — 14 of 24 objects avoided versus the 16/24 category average and the original Edge’s 16/24; keep floors clear of small objects the camera may miss. [5]
The 240 mL dustbin fills before docking in bulky-debris homes — below the 325 mL of the first generation and the 377 mL category average; run more frequent cleans. [5]
Heavy spills need about three passes — mopping is maintenance-grade, not spill remediation; expect repeated passes on dried spills. [7]
Occasionally gets hung up and does not return to the dock — one owner’s report; Roborock’s support attributes dock-not-found to starting elsewhere, manual moves or blocked paths, and most missed areas to a dirty right-side wall sensor. Fix: clean the wall sensor and keep at least 0.5 m clear on each side of the dock and 1.5 m in front. [7][4]
No automatic cleaning-solution dispensing — PCWorld lists it as a missing feature; if you want solution on the mops, add it to the tank manually. [6]
2.4 GHz Wi-Fi only — no 5 GHz and no WEP, so a 5 GHz-only or WEP network blocks setup; use a WPA or WPA2 network with a 2.4 GHz band. [4]
Battery endurance is below the predecessor — 1,208 sq ft per charge measured versus 1,369 for the original Edge; large or carpet-heavy floor plans will feel it most. [5]

Parts and consumables

Dust bags — $25.59 for a 6-pack at Roborock US (checked 2026-10); the bag is claimed to hold up to 65 days of debris, and one owner went through about 6 per year. [1][7]
Rotating mop cloths — $39.99 for a 4-pack (listed for Saros 20 and Qrevo Edge 2) at Roborock US (checked 2026-10); about 5 pads per year in the same test. [1][7]
Side brush — $15.99 for the Qrevo Edge Series at Roborock US (checked 2026-10); clean monthly, replace every 3–6 months, about 3 per year. [1][2][7]
Cleaning solution — $18.99 per 480 ml at Roborock US (checked 2026-10); about 4 bottles per year. [1][7]

Yearly running cost

Computed from one owner’s three-month real-home test cadence — 6 dust bags, 5 mop pads, 3 side brushes, 3 filters, 2 main brushes and 4 bottles of cleaning solution per year — priced against Roborock US list prices (checked 2026-10): dust bags $25.59 per 6-pack, rotating mop cloths $39.99 per 4-pack, side brushes $15.99 and cleaning solution $18.99 per 480 ml. Filter and main brush prices are not published in the sources, so a precise yearly total cannot be computed from the inputs; the same test rated the annual maintenance cost tier low. [1][2][7]

When it is a good buy

At or below $1,000 — strong buy for a pet home with low furniture; the official price was $1,099.99 against a $1,299.99 reference (Roborock US, checked 2026-10). [1][5]
$1,001–1,100 — the fair-value band; you pay for the dock, the cleaning scores and the slim body, accepting the threshold and obstacle-avoidance limits. [5][6]
$1,101–1,250 — MSRP territory; worth it only if the slim body and the mop dock are specifically needed. [5][6]
Above $1,250 — weak value for this exact model; flagship Saros models with climbing feet and 36,000 Pa suction (Saros 20 Sonic) are the rational comparison. [5][6]
