How to choose a self-emptying dock
- Bag or bagless. Bagged docks seal the dust away and you throw the whole bag out, which CHOICE notes could help if you have a dust allergy. Bagless cyclone docks (Ecovacs N20 Plus, X11 OmniCyclone) save on bags, but you still tip out a bin and clean the cyclone; techAU found dust trapped behind a rubber ring in the X11's canister.
- Budget for bags. Current Australian prices: Tapo $37 for five at JB Hi-Fi, Roborock $39.90 for three, Dreame $39.95 for three. At one bag every seven weeks or so, that's roughly $50–$100 a year. Check a brand sells bags locally before you buy.
- Claimed intervals are best cases. Brands quote 45 to 100 days between emptying. Pet hair, carpet and daily runs fill bags faster, and the robot's own bin is often small (180–400 mL), so it may empty mid-clean.
- Emptying is loud but short. Published or measured figures run from 72 dB (Qrevo C Pro) to 80 dB (X11 OmniCyclone). Most apps let you set quiet hours so the dock doesn't fire up at night.
- Measure the spot. CHOICE says self-emptying towers can be around 30–55 cm high. Docks that also wash mops are much bigger; the Dreame X50 Ultra's is 59 cm tall.

How we researched this
We shortlisted self-emptying robot vacuums sold by Australian retailers on 30 September 2026 and compared the docks: bag or bagless, capacity, claimed time between emptying, size and published noise, plus the price and availability of replacement bags in Australia. Robot specs come from manufacturers; performance notes come from the independent reviews linked with each pick. Prices were checked at Amazon AU and brand stores; some big-retailer pages didn't show prices to us. We haven't tested these robots ourselves.

Yes, briefly. Published and measured figures run from 72 to 80 dB for the few seconds the dock is emptying.
