Reviewers repeatedly praised the S2’s suction and airflow for strong pickup, sustained power, and confidence on debris-heavy cleaning, though not every carpet result matched the raw suction rating.
Pros: Cyclone performance, Suction and Airflow
Cons: Ongoing ownership costs (bags, filters
Vacuum suction and airflow were praised as superb or extremely effective in positive reviews, with carpet limitations showing up elsewhere.
Pros: Tool-change simplicity, Versatility
Cons: Value-for-money, Support and Reliability
Reviewers consistently praised raw suction and debris pickup on carpets and hard floors, with strong real-world cleaning results despite some measured pressure/battery tradeoffs.
Pros: Hair Pickup — Carpets, Large debris handling
Cons: Stuck resistance, Dirty water sensor
Suction and airflow are among the strongest attributes, with reviewers repeatedly praising powerful pickup despite a few real-world misses.
Pros: Sanitizing performance, Odor control
Cons: Fresh Liquid Pickup Speed, Ongoing ownership costs (bags
Suction was widely praised for everyday debris, dust, and hair, though one lab-style review warned that high advertised pascals did not translate into class-leading deep carpet results.
Pros: Hair-removal channel issues, Hair‑Wrap / Tangle Resistance
Cons: Accessories and Tools, Stair Cleaning
Reviewers generally found suction strong for everyday debris and smooth floors, with above-average airflow and praise for crumbs, pet hair and hard-floor pickup; carpet deep cleaning was treated more cautiously.
Pros: Versatility, Floor shine after cleaning
Cons: Odor control, Stuck resistance
Reviewers split between PCMag's suction stress-test concerns and several reviewers praising strong dog-hair, debris, and one-pass pickup.
Pros: Stuck resistance, Assembly and Setup
Cons: Clogging and debris prevention, Suitability for small spaces
Reviewers generally found real-world pickup strong, especially on hard floors and carpets, though one lab review measured unimpressive bench airflow and suction.
Pros: Maneuverability and Handling, Versatility
Cons: Under-Furniture Pickup, Low-profile design
Suction earned strong praise on hard floors and some carpets, but several tests found it less convincing for deep carpet dust and behind key rivals.
Pros: Fresh Liquid Pickup Speed, Ongoing ownership costs (bags
Cons: Filtration / Dust Containment, Under-Furniture Pickup
Reviewers treated the lack of suction as a clear limitation for solid messes, deep cleaning, and spotless results, with one reviewer saying the machine lacked power.
Pros: Noise level, Under-Furniture Pickup
Cons: Tool-change simplicity, Crevice / Groove Pickup (Hard Floors)
