For even cheaper options, head to TechRadar's best budget robot vacuum guide. If you're in the UK, our favorite budget model is the outstanding Xiaomi X20+.

Impressing with its pick-up on all tests, large crumbs, finer dirt and even pet hair posed no problems. It also consistently self-emptied its dust canister fully into the docking station.

You want a robot vacuum as a maintenance cleaner in between cleaning sessions with a full-size vacuum. Robot models fit easily under most beds and furniture to clean the spots you likely skip.

What sets this robot vacuum apart from the rest of the iRobot range is its ‘Dirt Detective’ feature, which means it automatically cleans the dirtiest rooms first and learns your cleaning habits, so it can make personalised suggestions to improve your routine.

These small-scale vacuums are ideal for cleaning up spilt food and keeping on top of dust in between more thorough cleans.

Given robot vacuums are best at keeping on top of mess rather than deep cleans, we don't see this as a big issue though. Plus, its mopping was excellent.

It’s heavier as a result, but it wowed our testers who said it didn’t smear any ketchup beyond the already stained area when cleaning – something rarely seen in the lab. Its vacuuming was also methodical and effective, lifting an average of 83 per cent of dust and dirt across the different test room floors.

All vacuums are tested exactly the same way for more accurate performance comparisons, and our tests are based on the ASTM International industry standard test methods.

Why have one vacuum cleaner when you can have three? Meet Eufy’s E20 model, which combines a robot, stick and handheld vacuum into one neat docking station so you can seamlessly switch between the three depending on the cleaning task at hand.

All the robot vacuums in this ranking have been rigorously tested, either by one of the TechRadar Homes team or an experienced reviewer. Meet some of the expert reviewers who tested the robovacs that feature in this guide.

It’s slower than a standard vacuum, taking 31 minutes on average to clean a whole room. But testers liked how it notifies you of areas it couldn’t reach — it sends pictures of obstacles through to the app, so you know to tackle them manually later. It also responded reliably to voice control, making it a good all-rounder.

Robot vacuums and mops are some of the most advanced appliances we test here at Top 3 Automatic Vacuum Cleaners the Good Housekeeping Institute, so we have high expectations, but even we’re still sometimes surprised by the innovations.

The benefit of the dinky size is that this bot can reach places bigger bots can't, and on test we found it navigated confidently around furniture legs and into tight spaces.

Navigation is excellent and this bot can also be relied upon to identify and avoid obstacles as required, meaning you can leave it to do its own thing without having to worry about it getting stuck or trying to suction up something it shouldn't. On test we also found it was great at hosting itself over tall thresholds.
