eufy Robovac 25C

If you're looking for a hassle-free way of keeping your floors clean but want to spend as little as possible, the eufy Robovac 25C is among the best cheap robot vacuums we've tested. Despite its very low price point, this budget-friendly robot vacuum delivers superb performance on bare, even surfaces like hardwood or tile. Its companion app is pretty sparse in terms of features but is pretty easy to use, and there's little lag when issuing a command with your phone

It also really struggles with sucking up debris on carpeted floors. While it does have the manufacturer's 'BoostIQ' feature, which is supposed to allow the vacuum to automatically adjust its suction power on different surfaces, it doesn't work as consistently on this vacuum compared to some other eufy models.
