That 30 d cleans like no other
I got a riccar 30d after having had a Miele upright for many years. Every time I use it I wish I had the old one back. Haven’t had prolux before so I guess maybe this isn’t helpful but next time I’ll be looking at Sebo. Unless Miele gets back into uprights.
If you want a really good canister vacuum and if price isn’t an issue, I’d recommend the Miele C3 Cat and Dog or a similar model with an electric power nozzle. I’d also either recommend the Sebo E3 or D4 with power nozzle. Both machines are very well built and will last you years if taken care of. I would absolutely NOT listen to the person who recommended the Rainbow vacuum and I personally would never recommend a water filter vacuum; with that much carpet and two cats you’ll be straight up cleaning mud out the vacuum every time you use it. If you want an upright, I’d recommend the Sebo Felix or Riccar R30D Tandem Air.
Many corded vacuums have headlights on their carpet powerheads but most do not have headlights on the hard floor/parquet brushes. The plush carpet needs a vacuum with physical carpet height adjustment and suction control helps too. I highly recommend trying these vacuums in person to see if they meet your needs. Miele C3 Marin has headlights on the SEB236 powerhead. It's a very good vacuum for carpets and hard floors and it's very quiet. Downsides are the standard tools are small so they fit in a compartment and the bags can leak if you don't reseat them every time you open the bag door. Riccar has several upright vacuums with headlights. The Riccar R25 Deluxe, R25 Premium Pet, R27 Deluxe, R27 Premium Pet have headlights, the Premium Pet models add dirt sensor lights that turn on when it detects dirt. The Tandem Air Upright Deluxe and Premium Pet also have headlights and dirt sensor lights on the Premium Pet. Riccar makes complicated vacuums that perform well but they are not as durable/reliable as Miele or Sebo. Prolux QX90 canister vacuum has headlights on its carpet powerhead. Prolux is not as expensive as Miele and Sebo but they are a step down in quality and reliability. I think they are still better than Kenmore canister vacuums and the many budget vacuums. There are also stick on led lights that you can attach to any vacuum that does not have headlights. While I like headlights that work on all surfaces, I would rather choose the vacuum that best meets my needs and I like overall the best. What do you think?
Riccar makes the best uprights with a huge selection. R40/r30 great for carpets and hardfloor, long hose, superior filtration to sebo. R27 great for hardfloor and very good on carpet. Long hose, again superior filtration to sebo.
They’re high end as well. I have a Tandem Air Upright, amazing machine! Every bit as good as Miele, Sebo, Lindenhaus.
Check out a Riccar Tandem Air Upright, amazing with carpet!
I’d go to a flooring store and see what their recommendations are. I have a Riccar Tandem Air that will deep clean your carpet. If you use the wrong vacuum you can and will void your warranty, it’s a crappy industry secret
