Robot vacuums get sold on the sticker price. A $1,999 flagship on special at $1,199 feels like a win, and it might be. But the machine keeps asking for money after it comes home. Brushes wear, filters clog, dust bags fill and mop pads go grey. And the dock quietly draws power 24 hours a day on a 240V circuit that never sleeps. If you are weighing up those ongoing commitments before buying, compare stick vacuums versus robot vacuums to see which appliance best suits your home.
Here is what those ongoing costs actually look like in an Australian home, and where you can trim them without shortening the life of the machine.
Consumables Are the Real Cost, Not Electricity
Most owners assume power is the big ongoing expense. It is not. Replacement parts are.
Typical manufacturer replacement intervals, taken from the user manuals rather than from testing:
- Side brush: every 3–6 months
- Main roller brush: every 6–12 months
- Washable filter: rinse monthly, replace every 3–6 months
- Mop pads or rollers: every 3–6 months
- Auto-empty dust bags: every 30–60 days for an average household, faster with pets or long hair
- Dock cleaning solution: one bottle every 2–4 months if you use it
Prices vary by brand, model and retailer, so the annual cost depends on your model. As a reference point, at the time of writing Roborock's official Australian store listed a three-pack of dust bags at $39.90, side brushes at $39.99 and a filter at $54.90. Replace parts like those on the manual's intervals and a self-emptying model can easily run to well over $100 a year in consumables. A basic vacuum-only robot with no dock, bags or mop pads to feed costs noticeably less. Check your brand's Australian store for your model's parts. Homes with a shedding dog go through bags and filters faster.
That is the number worth carrying into the shop. Over five years, consumables can quietly total a second robot vacuum.
The All-in-One Docks Cost More to Feed
The more the dock does, the more it consumes. A station that self-empties, washes the mop pads, refills the water tank and hot-air dries the pads has more wear items than a plain charging base. Those include dust bags, a cleaning-solution reservoir, dock filters, and mop pads that live a hard life in a wet tray.
Ecovacs' X2 Omni line is the clearest example of this trade-off: an unusually capable dock, and an unusually long consumables list to match.
Ecovacs Deebot X2 Omni Square Robot Vacuum
Best for: Larger Australian homes with a mix of hard floors and rugs where the owner wants a self-emptying, self-washing robot vacuum and mop that reaches into corners
What we like
- Square body that Ecovacs says cleans to within about 5 mm of the edge, for better corner coverage
- OMNI station auto-empties the dust bin, refills water, washes the mop pads with hot water and dries them with hot air, per Ecovacs Australia
- Ecovacs quotes 8000 Pa suction and a 15 mm mop lift for rugs and carpet
- Slim 9.5 cm robot height, which Ecovacs says lets it get under sofas and beds
- Ecovacs Australia lists a 2.5-year warranty
Worth knowing
- Ecovacs Australia's online store showed it as sold out when we checked, with a newer model suggested instead
- Station uses dust bags, an ongoing consumable to buy
- Home Assistant's Ecovacs integration is cloud-based by default and does not list the X2 by name
- Ecovacs' own pages disagree on the mop-wash water temperature and battery runtime
Proprietary detergent is where opinions split. Manufacturers specify their own low-foam solution because a normal floor cleaner can foam inside the dock's pump and sensors. Using something else may not damage the machine, but read your model's manual and warranty terms before you switch. The ACCC notes that consumer guarantees are separate from, and sit underneath, any manufacturer's warranty, so if a claim is knocked back, check the ACCC's guidance rather than taking the refusal as final. If the dock cleaning fluid is the part that annoys you, an alternative is to skip detergent entirely and run plain water, which most docks allow.
The Dreame L10s Ultra sits in the same all-in-one category. Its consumables — dust bags, mop pads, side brush, filter — are widely stocked through Amazon AU and eBay AU, which does keep replacement pricing competitive.
Dreame L10s Ultra Robot Vacuum and Mop
Best for: Mostly hard-floor homes wanting a camera-navigated robot that empties itself and washes and dries its own mops, and happy to use the Dreamehome app
What we like
- Dreame lists a base station that empties the dustbin, washes the mops, dries them with hot air, refills water and adds cleaning solution
- Dreame quotes up to 5,300Pa of suction and up to 60 days of hands-free cleaning from the 3L dust bag
- Navigation uses an RGB camera and 3D structured light, according to Dreame
- Works with Alexa, Google Assistant and Siri, per Dreame's product page
- Dust bags and an accessory kit are still listed on Dreame Australia's own store
Worth knowing
- The dock is large; Dreame gives its dimensions as 423 × 340 × 568 mm
- Navigation relies on an onboard RGB camera, which some households may not want roaming the home
- No longer shown in Dreame Australia's current robot vacuum line-up, and Dreame's direct warranty only covers purchases made from dreame.com.au
- The robot carries an 80mL onboard water tank, so it relies on the dock for refills during larger mopping runs
Electricity: Small, But Standby Draw Does the Damage
The cleaning run itself is cheap. A typical robot battery holds roughly 60–80Wh — a common Roborock pack, for example, is 14.4V and 5,200mAh, or about 75Wh — so a full charge with losses is around 0.1kWh. Clean daily for a year and that is under 40kWh, though your figure depends on the model, floor area and how often it runs.
The less obvious costs:
- Dock standby. A dock sitting idle at, say, 2–4W runs 8,760 hours a year. Call it 17–35kWh annually — often more than the cleaning itself.
- Self-empty bursts. Very high wattage, very short duration. Negligible over a year.
- Hot-air mop drying. This is the sleeper. Two to three hours of warm-air drying after every mop cycle adds up, and hot-water washing docks add a heating element on top.
Electricity rates vary by state, retailer and tariff, so use the rate on your own bill — or compare plans on Energy Made Easy (NSW, Qld, SA, Tas and ACT) or Victorian Energy Compare. Then multiply: a plain robot using roughly 55–75kWh a year across cleaning and dock standby costs that many kWh times your rate (at 30c/kWh, for example, 60kWh is $18). A full mopping-and-drying station will cost more, because its drying and water-heating cycles add consumption that varies a lot between models.
If you would rather know than guess, put a metering smart plug between the dock and the wall and read the actual consumption over a fortnight. It is the only way to get a figure for your home, your floor area and your cleaning schedule.
TP-Link Tapo P110 Smart Plug with Energy Monitoring
Best for: Renters and households wanting to see what individual plug-in appliances draw, using Alexa, Google Assistant or SmartThings without buying a hub
What we like
- TP-Link lists an Australian plug rated 220-240V with a 10A, 2300W maximum load, carrying RCM and SAA certifications
- Real-time energy monitoring in the Tapo app, with bill estimates based on single or time-of-use electricity rates, according to TP-Link
- No hub required, per TP-Link's setup instructions
- TP-Link says it adds overload protection and can switch off when draw passes a threshold you set
- Two-year TP-Link Australia warranty for smart power products bought from an authorised retailer
Worth knowing
- 2.4GHz Wi-Fi only, according to TP-Link's specifications
- The standard P110's Australian page does not list Matter or Apple Home support; that is the separate P110M
- Energy figures are estimates from the app; TP-Link publishes no accuracy figure on its Australian product page
One caution: check the plug's rated load against the dock's peak draw before you rely on it. Self-empty stations pull hard for a few seconds. TP-Link's Australian specifications list the Tapo P110, a plug that meters energy use, at a maximum load of 10A / 2300W. TP-Link also recommends keeping ongoing loads at 80% or less of the rated maximum. So read the dock's rating label too rather than assuming. Basic on/off plugs such as the Tapo P100 do not measure energy, so they cannot give you this figure. Never daisy-chain a dock through a travel adaptor or an unrated extension lead.
Batteries, Repairs and the Three-Year Cliff
Lithium batteries in robot vacuums are usually rated for several hundred charge cycles. Clean daily and you may see noticeably shorter runtime somewhere in the two-to-four-year window. Replacement pack prices vary by brand and by whether you buy genuine or compatible. At the time of writing, one Australian retailer listed a genuine Roborock 5,200mAh pack at $139.95. Check the brand's Australian store or an authorised retailer. On most models it is a few screws under the base plate rather than a service job.
Beyond the battery, the common failures are wheel motors, the brush motor, dock pumps and LiDAR turrets. Out-of-warranty repair pricing in Australia is inconsistent and often approaches the cost of a new mid-range unit.
Worth knowing: the ACCC says the consumer guarantee of acceptable quality usually still applies after a warranty expires. That is not the same as a guaranteed free repair, and outcomes depend on the circumstances. Read the ACCC's guidance on consumer guarantees and contact the business that sold you the vacuum before making a claim.
Where Generic Parts Make Sense, and Where They Do Not
Third-party consumables from eBay AU and Amazon AU are often a third of the genuine price. Some are fine. Some are not.
Usually safe to buy generic: side brushes, mop pads, dust bags. These are simple mechanical parts, and a poor one is obvious immediately.
Be more careful: filters and main brushes. A filter that does not seal properly lets fine dust bypass into the motor housing, which is a slow, invisible way to shorten the life of the machine. A cheap main brush with the wrong bristle stiffness cleans worse and can rub the floor plate.
Buy genuine: batteries. Cell quality and protection circuitry are not things you want to gamble on in a device that charges unattended.
A Realistic Five-Year Budget
Add it up for a mid-range all-in-one model, using your own numbers:
- Consumables: the brand's current Australian prices for bags, filters, brushes and mop pads, at the manual's replacement intervals
- Power: your metered kWh multiplied by your tariff
- One battery replacement across five years, if runtime drops
- Detergent, if used
Over five years the total depends on the model, your home and the prices you pay, but for a docked model the ongoing spend can add up to a meaningful share of the purchase price.
None of that makes robot vacuums bad value. It does mean the price of a three-pack of dust bags and a set of mop pads is a fair thing to check. Do it when you are comparing two models, before you tap the card. It also means a cheaper machine with widely stocked, non-proprietary consumables can end up costing less than a discounted flagship.
