Best robot vacuum and mop 2026: seven compared on what the mop does, whether it lifts on rugs and who washes it

Three questions, and all three are answered by looking at the listing and the maker's spec sheet. The answer is the mopping level you're buying, with what it does, what it doesn't do and what happens to the rug in the living room.

A robot mops in one of these five ways, and all five are sold with the same word. The ladder is only about the mop: the map of the house is a separate axis, and a robot with laser navigation can still be at level 1.

One, a damp cloth dragged along. Two, a pad that vibrates, which adds the scrubbing a dragged cloth lacks. Three, two spinning pads, the motion of a mop. Four, those pads and a dock that washes them with water from its tank. Five, that dock washing with hot water or drying with heat, which is what stops a stored pad from smelling.

The UK's consumer association is blunt about it in the open part of its buying advice. Robot mopping 'sounds fantastic', and then: 'In reality, we found ourselves doing even more cleaning.' Which? set each robot it assesses against jam and honey, and 'Even those with self-cleaning docks couldn't clear the grime.' It only recommends using a robot to mop light spills and stains, and it calls these machines 'maintenance tools rather than total replacements for a manual vacuum'.

That sets the ceiling, and the five levels explain what happens below it. A dried, sticky spill still calls for a mop and bucket. What the levels change is how much of the everyday light mopping the robot takes off you, and how much handling the pad needs afterwards. At level 1 the cloth wets and spreads what it finds; at level 3 two spinning pads work on marks instead of only wetting them; from level 4 you stop rinsing the pad by hand; and at level 5 hot water and heat drying deal with kitchen grease and with the smell of a pad stored damp.

A robot that mops and doesn't lift its pad goes over the rug with the wet cloth on. Four of the 39 Amazon Spain listings that promise to mop declare that lift; the other 35 say nothing, and in this category what isn't declared should be taken as not included. iRobot is the one maker in this selection that publishes the height: 10 mm, for its Roomba Plus 415.

There are two ways round it, and both work: a no-go zone for the rug in the app, which is only possible if the robot builds a map, or taking the mop off every time you want it to vacuum the whole house. The first is convenient and the second costs nothing, but it's worth knowing which one applies to you before you pay, because a gyroscopic robot can't do the first. If you ask us, with rugs at home the lift is the first line to look for on a spec sheet, before the dock: only 4 of the 39 listings declare it.

In the PDSA's PAW Report 2025, 30% of UK adults have a dog and 24% a cat, 11.1 million dogs and 10.5 million cats, so this is the common case rather than a niche. Three things decide it, and only one is the suction figure. The pascals belong to the vacuum half: they're what pulls hair out of a rug, and they say nothing about the mop. The second is who empties the bin: Which? notes that most newer models 'have self-emptying docks, which suck debris into a larger bag so you only have to empty it every month or two'. The third is the mop, because a dragged cloth wets a muddy paw print and spreads it, and a pad stored damp is where the smell starts: that's what the heat drying of level 5 is for.

We'd put a self-emptying dock ahead of a bigger suction figure if hair is the problem, because it turns emptying the bin into a job for every month or two, in Which?'s words, and no pascal figure does that. Eleven of the 39 listings in our count declare one.

The vacuum half is sold with a figure, the pascals. The mopping half isn't sold with any, and it's the half that brings a reader to this search, so we counted the whole catalogue in the category to see what can be known before paying.

There's a second reason the pascal figure doesn't settle anything. The ecodesign rules for vacuum cleaners, Regulation (EU) No 666/2013 in the version kept in UK law, cover mains-operated vacuums and 'shall not apply to' 'wet, wet and dry, battery operated, robot, industrial, or central vacuum cleaners'. No rule makes one robot maker measure its suction the same way as the next, let alone its mop.

The plug. Under the Plugs and Sockets etc. (Safety) Regulations 1994, nobody may supply a domestic appliance like this in the UK unless it is 'correctly fitted with a standard plug', a BS 1363 plug with a BS 1362 fuse, or with an approved conversion plug that encloses a non-UK plug and 'can only be removed by the use of a tool'. The dock is the part that plugs in, so check that the listing says UK plug before you pay, especially for a model sold across Europe.

Your 30 days and your six months. Under the Consumer Rights Act 2015 you have a short-term right to reject faulty goods that runs to 'the end of 30 days' after delivery (section 22), and a fault that shows up within six months of delivery is taken to have been there on the day it arrived, unless it's shown otherwise (section 19). A robot that loses its map or a dock that stops washing in the first weeks falls squarely here.

The app. Maps, no-go zones and schedules live in the maker's app, so the app is part of what you buy. On 14 December 2025 iRobot announced an agreement for Picea to acquire it 'through a court-supervised process', a pre-packaged chapter 11 it expected to complete by February 2026, and said it would keep operating 'with no anticipated disruption to its app functionality, customer programs, global partners, supply chain relationships, or ongoing product support'.

The consumables. A self-emptying dock uses bags; a washing dock also needs clean water in and dirty water out, and the top level adds filters and bags. The Roomba Plus 516's listing declares 90 days of dock autonomy before you have to touch the bag. Before choosing a dock, check that its bags, filters and pads are sold in the UK.
