Roborock P20 Ultra

Manufacturer: Roborock

The Roborock P20 Ultra is a feature-rich robot vacuum cleaner that handles both vacuuming and mopping in a single unit. Designed for largely hands-off operation, it supports full home mapping, scheduled cleaning runs, and automatic dust emptying through its docking station, which can go up to an estimated 56 days between manual interventions. It connects to Wi-Fi and is compatible with both Google Assistant and Amazon Alexa for voice control.

On the technical side, the P20 Ultra delivers 22,000 Pa of suction power across four cleaning modes and is rated for all floor types. Its 5,200 mAh battery supports up to 180 minutes of runtime per charge, with a full recharge taking approximately 2.5 hours. The unit weighs 3,800 g and measures 353 mm wide by 79.8 mm tall. It includes a HEPA filter, an allergy filter, washable filters, and an electrostatic filtration system. The mop system features automatic mop raising, cleaning, and drying, while additional sensors handle obstacle detection, anti-fall protection, and carpet detection. The dustbin holds 0.77 litres and the unit uses bags, with a full-bag indicator included.

Pros
  • With 22,000 Pa of suction and four cleaning modes, it handles both vacuuming and mopping across all floor types in a single unit
  • The self-emptying docking station can go up to an estimated 56 days between manual interventions, reducing routine maintenance significantly
  • A 5,200 mAh battery delivers up to 180 minutes of runtime per charge, allowing it to cover larger areas without interruption
  • Automatic mop raising, cleaning, and drying means the mopping system largely manages itself without user input
  • Comprehensive navigation features including mapping, route mapping, no-go zones, virtual barriers, and obstacle detection give users precise control over cleaning behavior
  • Both a HEPA filter and an allergy filter are included, along with an electrostatic filtration system and washable filters for thorough air filtration
Cons
  • At 64.5 dB, the operating noise level is noticeable and may be disruptive in quieter environments
  • The unit does not include a dirt sensor, so it cannot automatically detect and focus on heavily soiled areas
  • There is no physical remote control included, limiting control options to the smartphone app
  • The battery is not removable, which restricts options if battery capacity degrades over time
  • The warranty period covers only one year, which is relatively short for a device of this complexity
Who is this for?

This robot vacuum is well suited to users who want a largely hands-off cleaning routine, particularly those managing larger homes where up to 180 minutes of runtime and an estimated 56-day emptying interval reduce the need for frequent intervention. Households with mixed flooring will benefit from its ability to clean all floor types, automatically adjust its height, and raise the mop pad when transitioning surfaces. Those with allergy concerns will appreciate the combination of a HEPA filter, allergy filter, and electrostatic filtration system, which together provide thorough air filtration during operation. Users comfortable with app-based control will find the mapping, scheduling, no-go zones, and virtual barrier features give them precise oversight of the cleaning process.

Who is this NOT for?

Users who prefer simple, physical controls may find this unit limiting, as it lacks a dedicated remote control and relies entirely on smartphone-based management. Those in noise-sensitive environments — such as households with young children napping or people working from home — may find the 64.5 dB operating volume disruptive during cleaning cycles. The non-removable battery also makes this a less practical choice for users who expect to keep a device long-term and want the option to replace the battery independently as capacity degrades over time. Additionally, the absence of a dirt sensor means the unit cannot automatically prioritise heavily soiled spots, which may be a drawback for those dealing with high-traffic or frequently dirtied areas that require targeted attention.
