Every major robot vacuum brand sold in Singapore runs its own official web store, and we checked all six again on 10 November 2026, including what each cart actually charges. 11.11 is the story: Roborock's sale runs 10 to 15 November and puts the Qrevo S Pro at $629.90, Dreame's Mega Sale runs 9 to 12 November with cart vouchers, and Narwal now takes $500 off the Freo Z10 Ultra at checkout. Not every 11.11 price is lower than October's, and this comparison shows which ones are: what each store charges today, what is actually in stock, and which strikethroughs to ignore.
We re-checked all six official Singapore robot vacuum stores on 10 November 2026, cart prices included, as 11.11 pricing went live.
> Quick view: eufy Omni C28 $599 with its code, still the cheapest roller mop · Roborock Q7 TF+ $299.90, the cheapest self-emptying robot · Roborock Qrevo S Pro $629.90 in its 11.11 sale to 15 Nov · Narwal Freo Z10 Ultra $1,099 net. The catch: Dreame's 11.11 cart prices are not all lower than October's.
Dreame's homepage banner dates its 11.11 Mega Sale 9 to 12 November, "up to 40%" with online-exclusive vouchers and free gifts.THE DEAL: every in-stock robot picks up an automatic November voucher in the cart (DREAMENOV10OFF to DREAMENOV65OFF), with nothing to type. The X60 Ultra Extreme goes from $1,914 to $1,849, the X60 Ultra from $1,664 to $1,599, the Matrix10 Ultra to $1,524, the Aqua10 Ultra Roller to $1,534 and the back-in-stock X50 Pro Master to $1,634, each $65 off. The X50 Ultra is $1,199 ($50 off), the Aqua10 Roller AE $914 ($35 off), the D30 Ultra CE $657 and the D20 Ultra $517 ($22 off), and the F20 $369 ($10 off). Flagship carts also add free gifts, with a V11 Pro cordless vacuum in the X60 Ultra Extreme's.FINE PRINT: several tiles went up before the vouchers, so the Aqua10 Roller AE, X60 Ultra Extreme and F20 now cost more in the cart than in October ($899, $1,799 and $319 then). The Matrix10 Ultra ($210 less) and X50 Ultra are the real 11.11 cuts.STOCK CHECK: the X60 Master Extreme ($2,109), X50 Pro Ultra, Aqua10 Roller ($1,299), Aqua10 Pro Track ($1,364) and L10s Ultra HEAT ($999) are out of stock, and the dockless D20 has left the store.BEST FOR: buyers who want a specific feature at a specific price. Dreame's usual prices are still the most believable of the six.

ECOVACS sells in Singapore through ecovacstineco.com.sg, its official local store.WHAT CHANGED: the DEEBOT T30C Prime Omni, its cheapest robot with a self-washing station, dropped $50 to $549 (U.P. $2,399).THE DEAL: the T90 Pro Omni still shows $1,199 on its tile, and an automatic "[T90 PRO OMNI] $100 OFF" discount takes it to $1,099 in the cart. No other ECOVACS robot gets a cart discount. 11.11: a homepage Spend & Win banner runs 1 to 17 November with a minimum spend of $900 and no registration, so a T90 Pro Omni or X12S OmniCyclone order qualifies, while the $899 T80 and T50S models fall $1 short. It is a prize draw, not a discount.PRICES NOW: T80 Max Omni $899 (U.P. $3,999) and T80 Omni $899, both roller mops, T50S Pro Omni $899, X12S OmniCyclone $1,549, T30C Max Omni $749, N30 $349 and N30 Plus $419.STOCK CHECK: the X12 Pro Omni ($1,349) and DEEBOT Mini 2 ($499) are out of stock.FINE PRINT: the T30C Max Omni is still listed twice, at $749 against a "$2,599" usual price and, under a COMEX26 label, at $779 against "$2,399". Same machine, two usual prices, so take the $749 one.BEST FOR: anyone who wants to price-check before buying. ECOVACS is carried by Courts, Gain City, Harvey Norman and FairPrice locally, so ignore the left-hand numbers and compare the selling price across sellers.

MOVA runs its own Singapore store at mova.sg, and its homepage now links an 11.11 Super Sale collection.THE DEAL: automatic vouchers still come off in the cart with no code to enter. The S70 Roller drops from $779 to $752, and the cart adds a free 1-year extended warranty MOVA values at $149 plus two more free items. That keeps it the cheapest roller mop here after eufy's Omni C28: 28,000 Pa suction, an 80°C self-cleaning roller, a 5L clean-water tank and a 90mm body.PRICES NOW: the V70 Ultra Complete (pictured) and the Z70 Ultra Roller are both $1,399 (U.P. $1,799), or $1,329 after a $70 voucher, and each cart adds the extended warranty and a 1.5-year accessory pack free, plus an Aero C hair dryer with the V70. The E40 Ultra is back in stock at $549, or $534 in the cart.STOCK CHECK: the V50 Ultra Complete ($1,099) and Z50 Ultra ($1,099) are sold out, so four robots can be ordered. MOVA publishes no end date, and its announcement bar still reads "October Home Upgrade Sale".FINE PRINT: the S70 Roller's discount is quoted against a $2,299 usual price, well outside the rest of MOVA's own pricing, which is why it shows as 66% off.BEST FOR: a roller mop on a budget, with a longer warranty thrown in.
11.11 Super Sale with automatic cart vouchers, no end date (checked 10 Nov 2026): S70 Roller $779 → $752 + free 1-year extended warranty (worth $149) · V70 Ultra Complete $1,399 → $1,329 · Z70 Ultra Roller $1,399 → $1,329, each with the warranty and a 1.5-year accessory pack free · E40 Ultra $549 → $534, back in stock.

Narwal's Singapore store at sg.narwal.com raised its one cart discount for 11.11.THE DEAL: the Freo Z10 Ultra is listed at $1,599 and its product title now reads "Get $500 OFF at Checkout". We added it to a cart on 10 November and a "Z10 Ultra-500" discount came off, landing it at $1,099, $100 less than on 26 October. The Auto Water Kit version is $1,398 after the same deduction.WHAT ELSE MOVED: the Flow dropped $200 to $1,499 (Auto-Water $1,699).PRICES NOW: Freo 20 $1,899, Freo 20 Edge Track $1,399, Flow 2 $1,999 (accessories bundle $2,229) and Freo X10 Pro $799 (Autowater Kit $1,098), still Narwal's cheapest new docked machine. The Z10 ($999) is still sold out. A Flow 2 (Compact Station) listing now shows $2,499 against "$6,999", but it would not go into a cart on 10 November.SAMPLE SALE: four grades, described as 100% functional with slight cosmetic imperfections, all with the 2-year warranty: an X10 Pro at $449 (9.5/10), a Z10 at $499 (9.5/10), a Z10 Ultra at $699 (9.9/10) and a Flow at $899 (9.9/10). The $599 Z10 Ultra grade has sold out.FINE PRINT: disregard the strikethroughs. $5,399 on the Freo Z10 Ultra, $6,999 on the Flow 2 and $6,299 on the Freo 20 are not prices anyone in Singapore has paid. Narwal backs its robots with a 2-year local warranty (accessories excluded) from its office at 1 Irving Place, #06-09, The Commerze@Irving.BEST FOR: mop hygiene above everything, for the self-washing base and the mop-lifting on carpet.
Freo Z10 Ultra $1,599 with $500 off applied at checkout, $1,099 net (cart-tested 10 Nov 2026; was $400 off). Flow $1,499 (was $1,699) · Freo 20 $1,899 · Freo 20 Edge Track $1,399 · Flow 2 $1,999 · Freo X10 Pro $799. Z10 ($999) sold out.

eufy, which now trades as Anker eufy, reset its product-page codes on 30 October, and every one is smaller than before.WHAT CHANGED: the Robot Vacuum Omni C28 is $699, and WS24C28SG now takes $100 off instead of $124, so $599, up $24. The page still adds a free replacement kit eufy values at $99 (side brushes, filters, dust bags, a roller brush and two roller mops). It is still the cheapest roller mop in this article, with 15,000 Pa suction and a 5-in-1 station that empties, washes, hot-air dries and refills itself.PRICES NOW: the Omni C20 is $499 → $417 (WS24C20SG), and its station also empties, washes, dries and refills, which keeps it the cheapest all-in-one station here. Only Roborock's Q7 TF+ at $299.90 empties itself for less, and its dock does not wash a mop. The flagship Robot Vacuum S2, with 30,000 Pa and a roller mop, is $1,599 → $1,399 (WS24WS2PSG).STOCK CHECK: the Omni E28 ($999 with WS24E28SG) and E25 ($753 with WS24E25SG) both show as unavailable, so you cannot order them.FINE PRINT: every code sits in a COPY box on the product page rather than applying by itself, so take it with you to the cart. The pages say "Hurry! Offer Ends Soon!" without a date, and the codes carry no end date.BEST FOR: the cheapest roller mop (C28), the tightest budget for a full station (C20), or a flagship roller mop for the price of Roborock's Saros 20 Flow Complete (S2).
On-page codes reset 30 Oct, checked 10 Nov 2026: Omni C28 $699 → $599 with WS24C28SG, plus a free replacement kit (worth $99), the cheapest roller mop here · Omni C20 $499 → $417 with WS24C20SG, the cheapest all-in-one station · Robot Vacuum S2 $1,599 → $1,399 with WS24WS2PSG · Omni E28 ($999 with WS24E28SG) and E25 ($753 with WS24E25SG) OUT OF STOCK.

Robot vacuum listings in Singapore have a strikethrough problem, and it makes the discount badges useless as a comparison tool.
You do not need an outside source to prove it. ECOVACS still lists the same DEEBOT T30C Max Omni twice on its official Singapore store: at $749 against "$2,599", and under a COMEX26 label at $779 against "$2,399". One store cannot hold two usual prices for one machine, so at least one of them is invented. Its X12S OmniCyclone sells at $1,549 against "$5,299". Narwal does the same thing harder: the Freo Z10 Ultra at $1,599 against "$5,399", the Flow 2 at $1,999 against "$6,999" and the Freo 20 at $1,899 against "$6,299".
Now compare that with Dreame, whose in-stock tiles read $379 to $1,914 against usual prices of $449 to $2,699, and Roborock, whose Saros 20 is $1,199.90 against $2,099.90. Those are gaps a retailer can actually defend.
The consequence is simple but easy to get wrong: a 77%-off badge and a 30%-off badge tell you nothing about which machine is cheaper. Put the selling prices side by side and ignore everything to the left of them. Better still, put the cart prices side by side, because four of the six now take money off only after you click Add to cart.
Five routes cost less than the entry price on the front page, and none of them is advertised there.
On the number you actually pay rather than the discount badge, the pick on 10 November 2026 is still eufy's Omni C28, at $599 with its code WS24C28SG plus a free replacement kit eufy values at $99. It is the cheapest roller mop here with a station that empties, washes, dries and refills itself. Next comes MOVA's S70 Roller at $752 after its automatic cart voucher, then ECOVACS' T80 Max Omni and T80 Omni at $899 each. Roborock's 11.11 sale, which runs to 15 November, changed the middle of the market: the Qrevo S Pro is $629.90 and the Qrevo Edge 2 Flow roller mop $959.90. Higher up, Narwal's Freo Z10 Ultra works out at $1,099 after its $500 checkout discount, and Roborock's Saros 20 is $1,199.90 in the same sale. On a tight budget, eufy's Omni C20 at $417 is the cheapest full station, and Roborock's Q7 TF+ at $299.90 is the cheapest robot that empties its own bin, though its dock does not wash a mop.
More than fifteen machines qualify on 10 November 2026, and the order is not what the discount badges suggest. eufy's Omni C28 is $599 with its code and is the only roller mop under $750. ECOVACS' T30C Prime Omni is now $549 and empties and washes itself, and Roborock's Qrevo S Pro is $629.90 in its 11.11 sale to 15 November. For a roller mop, MOVA's S70 Roller is $752 in the cart, followed by ECOVACS' T80 Max Omni and T80 Omni ($899 each), Dreame's Aqua10 Roller AE ($914 in the cart) and Roborock's Qrevo Edge 2 Flow ($959.90 to 15 November). Narwal's Freo X10 Pro is $799, Roborock's Qrevo 2 Pro is $799.90 (or $599.90 in its 10-minute flash sale at 7.50pm on 10 November) and its Qrevo Edge 2 is $859.90. Narwal's sample sale starts at $449 for a 9.5/10 X10 Pro with the full warranty. Below $500, eufy's Omni C20 at $417 is a full station, while Roborock's Q7 TF+ ($299.90) empties itself but leaves the mop to you. Leave out eufy's E28 and E25: both are out of stock.
Pick by what the machine has to do, because at these prices the brands overlap heavily. Roborock is the navigation and mapping choice, and its 11.11 sale to 15 November is the strongest of the six: the Qrevo S Pro is $629.90, the Saros 20 $1,199.90, and the Q7 TF+ at $299.90 is the cheapest self-emptying robot here. Dreame gives you the widest range and the most credible strikethroughs, and its 11.11 Mega Sale takes $10 to $65 off every in-stock robot in the cart until 12 November, from the F20 at $369 to the X60 Ultra Extreme at $1,849. Check the cart total, though, because some Dreame tiles rose before the vouchers. MOVA is Dreame's budget-focused sibling: its S70 Roller is $752 in the cart with a free 1-year warranty extension. Narwal is the one to consider if mop hygiene is the whole point, with the $500 checkout discount making the Freo Z10 Ultra $1,099. ECOVACS makes genuinely good hardware, now sells the T30C Prime Omni at $549, and is the only one of the six carried widely by Courts, Gain City, Harvey Norman and FairPrice, so it is the easiest to sanity-check. eufy is the value pick at both ends once you apply the codes on its pages: the Omni C28 at $599 and the Omni C20 at $417.
Because a strikethrough price on a Singapore web store is not a regulated figure, and three of these six brands are using numbers that no local buyer ever paid. The proof is on ECOVACS' own store, and it does not need an outside source: the DEEBOT T30C Max Omni is listed twice, at $749 against a "$2,599" usual price and, under a COMEX26 label, at $779 against "$2,399". One store cannot hold two usual prices for one machine, so at least one of them is invented. Narwal shows the Freo Z10 Ultra against $5,399, the Flow 2 against $6,999 and the Freo 20 against $6,299, on machines selling at $1,599, $1,999 and $1,899. MOVA's S70 Roller carries a $2,299 usual price that sits well outside the rest of MOVA's own pricing. By contrast, Dreame's usual prices ($449 to $2,699 on machines selling at $379 to $1,914) and Roborock's ($2,099.90 against $1,199.90 on the Saros 20) are within a range you could plausibly have paid. The practical rule: compare the selling prices of the machines you are choosing between, and treat every percentage badge as marketing.
For hard flooring, yes, and it is the one specification difference on this list worth paying for. Spinning pads carry the same cloth around the whole floor, so once the pad is dirty the machine is redistributing that dirt until the dock washes it. A roller mop is rinsed and scraped continuously against a clean-water feed as it turns, so what touches the floor stays closer to clean across a full run. It also reaches closer to skirting boards on most designs. As of 10 November the roller machines you can order here are eufy's Omni C28 ($599 with its code) and Robot Vacuum S2 ($1,399 with its code), MOVA's S70 Roller ($752 in the cart) and Z70 Ultra Roller ($1,329 in the cart), ECOVACS' T80 Max Omni and T80 Omni ($899 each), Dreame's Aqua10 Roller AE ($914 in the cart) and Aqua10 Ultra Roller ($1,534 in the cart), and Roborock's Qrevo Edge 2 Flow ($959.90 to 15 November) and Saros 20 Flow Complete ($1,399.90). Dreame's Aqua10 Roller and Aqua10 Pro Track, Roborock's Qrevo Curv 2 Flow and eufy's E28 and E25 are out of stock. If your home is mostly carpet or rugs, this matters far less, and you should prioritise mop-lifting height and suction instead.
For a typical 3- or 4-room HDB flat you are buying for floor type and dock placement, not for suction numbers or battery life. Almost any docked machine on this list will finish a flat that size on one charge, so the specifications the marketing leads with are the ones that matter least to you. Two things do matter. First, HDB flats are mostly tiles or vinyl rather than carpet, which is exactly the case where a roller mop beats spinning pads, so eufy's Omni C28 at $599 with its code, MOVA's S70 Roller at $752 in the cart and ECOVACS' T80 Max Omni at $899 are doing more for you than a pricier machine with pads. Second, the dock is the real constraint: it is a permanent piece of furniture that needs its own power point and clearance on both sides, and in a smaller flat the honest question is where it goes before which model you buy. Measure the spot first. If navigation in a cluttered flat is your worry, Roborock's Qrevo S Pro at $629.90 until 15 November gives you its navigation and a self-washing dock. For a room, a rental or a second unit where you only want daily crumb patrol, Roborock's Q7 TF+ at $299.90 empties itself, and Dreame's F20, with no self-emptying station, is $369 in the cart.
As of 10 November 2026, two of the six publish an end date. Dreame's homepage banner dates its 11.11 Mega Sale 9 to 12 November, and Roborock's site dates its 11.11 sale 10 to 15 November, with a separate 10-minute flash sale from 7.50pm to 8pm on 10 November. ECOVACS' Spend & Win draw runs 1 to 17 November, though its $100 off the T90 Pro Omni has no date. MOVA's cart vouchers, Narwal's $500 checkout discount and eufy's codes (reset on 30 October) carry no end date, and eufy's product pages say "Hurry! Offer Ends Soon!" without one. Expect prices to move again once the dated sales close: after Roborock's 10.10 sale ended on 17 October, its prices came back above their pre-sale level within nine days.
Buy from whichever is cheaper on the day, but check the warranty path before you do, and remember that the best prices in this article only exist on the brands' own sites. eufy's codes are displayed on eufy's own product pages, Narwal's $500 is deducted in Narwal's own cart, Dreame's and MOVA's 11.11 vouchers and MOVA's free warranty extension only appear in their own carts, and Roborock's Certified Refurbished shelf, auction listings and 10-minute flash sale exist nowhere else. None of those is guaranteed to appear at a third-party retailer. ECOVACS is the exception worth shopping around on: it is carried by Courts, Gain City, Harvey Norman and FairPrice locally, so its official-store price is easy to sanity-check against four other sellers. Narwal states a 2-year local warranty on its robot vacuums, excluding accessories, serviced from its Singapore office. Wherever you buy, make sure the seller is an authorised local channel rather than a parallel importer, because dock parts, mop rollers and filters are the consumables you will need locally in a year's time.
For some brands, not all. Roborock's 11.11 prices on 10 November undercut its own 10.10 sale on the Saros 20 ($1,199.90 against $1,299.90) and the Qrevo Edge 2 Flow ($959.90 against $999.90), and the Saros 20 Sonic is $300 cheaper than two weeks ago. The Qrevo S Pro at $629.90 is $70 under late October but still $30 above its 10.10 price. Narwal's Freo Z10 Ultra is $100 cheaper than in October. Dreame is mixed: its 11.11 vouchers sit on tiles that went up first, so the Aqua10 Roller AE, X60 Ultra Extreme and F20 cost $15 to $50 more in the cart than they did in October, while the Matrix10 Ultra is $210 cheaper. eufy's codes shrank on 30 October, adding $24 to the Omni C28 and $124 to the Robot Vacuum S2. The practical rule is the same as at every sale: compare the cart total with the last price you saw, not with the strikethrough, and screenshot it on the day you decide, because prices also rebound after a sale ends, as Roborock's did after 10.10.
