Smart cleaning is not one purchase decision: a robot built for mopping floors solves a different problem than one for vacuuming, cat litter, or windows. The clearest way to choose is to start with the chore, then weigh the level of automation, control options, condition, and the $251.05 spread across these four options.
Quick take
- Choose the Lefant T1 for a mopping-focused robot with a self-cleaning base, hot-air drying, and voice-assistant compatibility.
- Choose the iRobot Roomba Plus 4020 Combo when you want cordless vacuuming and mopping in one robot, with smart mapping, room-by-room navigation, and auto mop washing.
- Choose the PETKIT PuraMAX 2 for automatic cat-litter cleaning with Wi-Fi and PETKIT app control.
- Choose the TOSIMA W5 when windows are the specific cleaning task and a corded electric robot suits the job.

- Cat-litter maintenance: The PETKIT PuraMAX 2 is purpose-built as a self-cleaning litter box, with Wi-Fi connection and PETKIT app control.
- Window cleaning: The TOSIMA W5 is identified for windows and uses a corded electric configuration.
Product notes
T1 Smart Self-Cleaning Robot Mop with Lidar, 5L Tank, Alexa Compatible
The Lefant T1 makes sense for a mopping routine that benefits from dock-based care. Its title highlights Lidar and Alexa compatibility, while its compatible-device list includes Amazon Echo, Google Home, smartphones, tablets, and voice assistants. After mopping, the robot returns to the dock for mop-cloth cleaning and hot-air drying. At USD 132.09, it occupies the middle of the price range while concentrating on mopping and self-cleaning base functions. The main constraint is its battery setup: batteries are included, but batteries are also required as part of the configuration.
Smart Cleaning Robot iRobot Roomba Plus 4020 Combo Robot Vacuum Mop w/ Auto wash
Pick the iRobot Roomba Plus 4020 Combo when a cordless robot needs to handle both vacuuming and mopping. It has a stated 120-minute runtime and 2-hour charge time, plus smart mapping, room-by-room navigation, LiDAR navigation, app control, auto-docking, and auto mop washing. An AutoWash Dock, line cord or power cord, extra AutoEmpty bag, and extra dual spinning mop pads are included. At USD 299.95, it has the highest listed price in this comparison. That price position is the central tradeoff for its combined vacuum-mop format and included dock accessories.
PETKIT PuraMAX 2 Automatic Smart Cat Litter Box Self-Cleaning Cat Litter Box
For cat-litter maintenance, the PETKIT PuraMAX 2 is the specialized choice among these four. It is a self-cleaning litter box with the xSecure System, Wi-Fi connectivity, PETKIT app control, and a 2.4 GHz Wi-Fi connection. At USD 244.99, it sits below the iRobot Roomba Plus 4020 Combo while addressing an entirely different household task. Its limitation is important to match to your setup: the unit is in Very Good - Refurbished condition and is the PuraMax version without the Air Purifier Odor Removal Spray.
TOSIMA W5 Window Cleaning Robot, Black, Corded Electric Smart Cleaning Device
The TOSIMA W5 fits a household where windows are the priority rather than floor or litter maintenance. It is a black, corded electric robot identified for windows, with a capacity of less than 1 gallon. At USD 48.90, it is the lowest-priced option in the group and is aimed at a narrowly defined cleaning job. The tradeoff is condition: it is used, and it should be deep cleaned before use. It is described as complete with accessories, making it a focused option for someone specifically seeking a window-cleaning device.
Final recommendation by use case
Choose the Lefant T1 for mopping with a self-cleaning, hot-air-drying base and broad voice-assistant compatibility. Select the iRobot Roomba Plus 4020 Combo when you want a cordless vacuum-mop with smart mapping and auto mop washing. For an automated cat-litter routine, the PETKIT PuraMAX 2 is the direct fit, keeping its refurbished condition and no-spray configuration in mind. If the task is windows, the TOSIMA W5 is the purpose-specific, corded option.
