Roborock Q7 L5
The most complete package under $400: LiDAR mapping, 8,000Pa suction with dual anti-tangle brushes, and electronic mopping backed by the best app in the class. If you buy one robot and stop researching, buy this one.
- LiDAR mapping + top-tier app
- 8,000Pa suction
- Anti-tangle brushes for pet hair
Dreame D20 Plus
A vacuum-first combo that mops genuinely well, with LiDAR navigation and a large dustbin. Hard-floor-dominant homes get the most from it — the mopping system is tuned for tile, laminate and wood.
- LiDAR navigation
- Excellent hard-floor mopping
- Large dustbin
Tikom G8000 Max
The cheapest credible combo here. App control is basic and navigation is simpler than the LiDAR pair, but it handles paw prints and spills in small flats without complaint — the right first robot.
- Lowest price of the four
- Handles pet messes
- Great for small apartments
iRobot Roomba 115X Combo
iRobot's budget combo trades raw specs for simplicity: a friendly app, dependable spares availability and cleaning that just works. A good pick for first-timers and smaller homes.
- Simplest app experience
- Easy spares and support
- Dependable daily cleaning
How to choose
Spend first on navigation. LiDAR mapping (the Roborock and Dreame here) builds a real floor plan, cleans in straight lines and respects no-go zones; camera-and-gyro bots wander and re-clean the same corner. Next, check the mop: vibrating or pressurised pads lift dried spills, while a static pad mostly redistributes dust. Pet homes should prioritise anti-tangle brushes and a big dustbin over headline suction numbers.

Frequently asked questions
Can a robot vacuum mop replace a real mop?
For weekly maintenance, yes — the electronic mops here handle paw prints, spills and dried drips. Deep grout cleaning still wants a human and a bucket every month or two.
How often do I need to empty the dustbin?
Most budget combos hold two to four days of debris for an average flat. If you have shedding pets, empty after every run or step up to a self-empty dock model.
Do robot vacuums work on dark carpets?
Most cliff sensors can mistake very dark carpet for a drop-off. Check the app for a carpet-boost and sensor-override setting before buying for a dark-floored home.
