Roborock Qrevo S Pro: problems, parts and running costs
Checked: 2026-10-06
Summary
The Qrevo S Pro is a strong mopper and a weak vacuum on carpet with hair: Vacuum Wars measured 43% pet-hair pickup (82% category average), 62% hair tangling (26% average) and 5-of-24 obstacle avoidance (16 average) [2]. Running costs are dust bags every ~65 days, mop pads, washable filters and optional cleaning solution; a UK dust-bag pack of six cost £31.99 at the time of T3’s review [3]. At $429.99 from Roborock US it is a good buy for hard-floor homes without heavy shedding pets; above roughly $500 the case weakens fast [1][2].
Common problems and fixes
- Pet hair on carpet — Vacuum Wars measured 43% pickup of flattened 2.5-inch pet hair versus an 82% category average; their FAQ answer to “is it good for pet hair” is “No” [2]. No fix; hardware limitation. Not covered by warranty as a defect.
- Hair tangling on the brush — 62% of 7-inch hair wrapped onto the brush versus a 26% average, despite the “Anti-Tangle Side Brush” marketing [1][2]. Clean the brush regularly; no warranty fix.
- Weak obstacle avoidance — 5 of 24 obstacles avoided versus a 16 average; T3 saw the robot push toys and socks lodge in the roller [2][3]. Pre-clean floors before runs; no fix.
- Loud dock emptying — T3 measured 70 dB at the dock, enough to drown out a TV; VacuWiz owners report it is audible from another room [3][9]. Schedule emptying for empty-house hours.
- Large dry debris pushed around — T3’s reviewer found multigrain cereal swept in circles rather than picked up [3]. No fix; pick up large debris before runs.
- Light mopping — mopping wets rather than scrubs; dried-on wet food residue needed manual scrubbing [3]. No fix; pre-treat stubborn stains.
- Long-pile and fringed rugs stall the robot — VacuWiz owner reports say these rugs can stall or tangle the robot [9]. Set them as no-go zones and clean by hand.
- Small onboard dustbin — 330 mL versus a 377 mL category average; heavy-pet homes may fill it mid-cycle [2]. Empty more often or rely on dock self-emptying.
Parts and consumables
- Dust bag — replaced about every 65 days; one pre-installed at delivery. T3 priced a UK pack of six at £31.99 (June 2026) [3]. Roborock US sells replacement dust bags [1].
- Mop pads / mop cloths — recurring replacement item; Roborock US sells 4-packs for the Qrevo line [1].
- Washable filters — Roborock US sells a 2-pack for the Qrevo S / Qrevo MaxV / Qrevo Pro / Qrevo Plus family [1].
- Floor cleaning solution — optional; Roborock US lists a 480 ml bottle at $18.99 [1].
Yearly running cost
Dust bags: about every 65 days, so roughly 5–6 per year; T3 priced a UK pack of six at £31.99 (June 2026) [3]. Mop pads and filters: replacement intervals not stated in the sources; Roborock US sells multi-packs but no US price was read [1]. Floor cleaning solution: $18.99 per 480 ml bottle as needed [1]. Electricity for dock charging and the 167°F mop-wash cycle: not quantified in the sources. US dust-bag price was not read.
When it is a good buy
$429.99 at Roborock US (checked October 2026) is defensible for a mostly hard-floor home without heavy shedding pets [1][2]. Above roughly $500 the value weakens because the weaknesses are hardware, not firmware [2]. At the $699.99 list price it is not competitive [2]. Alternatives: the Dreame L40s Ultra measured better at vacuuming (92% carpet deep clean, 91% pet-hair pickup, 0% tangling) and slightly worse at mopping (38.5 vs 39.4) — the better choice for carpet-and-pet homes [2]. The SwitchBot Mini K10+ Pro is T3’s budget alternative at the same ~$429.99 price point but is physically smaller [3].
