Detailed Test Results

Like other Eufy's, the 35C seemed to clean in a random pattern even though it claims to use different modes to optimize cleaning. This vac was not as calculated in its movements as some of the other models. We noticed that it scattered debris with its two side brushes but eventually picked it up after passing over it at least a second time. With a very slim profile height of under 3 inches, it was low enough to get under our test furniture with some room to spare.It has a spiral combo bristle/rubber blade brushroll that is easily removed to clean. Most of the test hair was caught in the brushroll and wasn't as easy to remove but wasn't as difficult to remove as other models. It took a few tugs to get the hair out of the bristles. The large track type wheels with suspension easily climbed over our .5 inch thresholds. It's suction wasn't as good as come models as it struggled to pick up fine dust from our carpets. This vac did not get caught up in rug tassels or electrical cords and navigated over dark carpets. This model has more buttons on its conrol panel than the Eufy 15C: you can use spot mode, or send it to charge without the remote or the app. Features: auto, quick, edge, spot and manual cleaning cycles. Suction: standard and max. Boost IQ - automatically switches between standard and max suction based on the floor type. App: EufyHome version 2.4.1: allows you to schedule cleaning and is compatible with Amazon Alexa and Google Assistant. Battery: Li-ion (14.4V,2600mAH,37.44wH). Includes: Two extra side brushes, extra filters, and a cleaning brush for the brushroll, magnetic strips, adhesive tape, remote, docking station and wire ties to organize cords. It has a 1 year limited warranty.

About

Carpet: A high score means the vacuum effectively removes surface debris and embedded dust from medium-pile carpet. A top-scoring model picks up more debris from carpet per run.

Bare floors: A high score means the vacuum effectively removes surface debris like sand from smooth hard floors. A top-scoring model picks up more debris from non-carpeted flooring per run.

Navigation: A composite score that includes combined coverage over multiple runs, clearance under furniture and obstacle and entrapment avoidance.
